Description
LAMINATED PANEL AND PROCESS
CROSS-REFERENCE TO RELATED APPLICATIONS
The present patent application claims priority on United States Provisional Patent Application No. 60/587,516, filed on July 14, 2004, and on United States Provisional -Patent Application No. 60/605,138, filed on August 30, 2,004.
TECHNICAL FIELD
The present invention generally relates to a lamination process and, more particularly but not exclusively, to a process for laminating various layers into a laminated panel, for subsequent use of the laminated panel as a component of a boot quarter, for sporting goods or the like.
BACKGROUND ART
Laminated panels are found in a plurality of products. Laminated panels typically consist of a plurality of 'layers, each layer being part of the laminated panels for given properties. Therefore, laminated panels are used as an alternative to well known materials, such as leather and polymers (e.g., vinyl), in the fabrication of goods.
The layers constitut,ing laminated panels are chosen for various properties that will suit the subsequent use of the product. For instance, layers having properties such as resilience, impermeability, strength, shock absorption, softness, are combined to be laminated into panels that will have selected characteristics.
The lamination processes typically involve a continuous feed of the layers into ,presses, and therefore involve expensive equipment. Moreover, effects such as embossing are desired on some panels, and this involves further equipment, for instance to synchronize embossing dies with the feed of material in the lamination process.
It would thus be desirable to simplify the lamination process and to lessen 'the cost of equipment involved in the process, for instance when embossing is required in the laminated panels.
SUMMARY OF INVENTION
Therefore, it is a feature of the present invention to provide a novel method for laminating panels.
It is a still further feature of the present invention to provide a novel laminated panel.
Therefore, in accordance with the present invention,. there is provided a laminated panel comprising: a fusible layer having an upper surface;
and a mesh layer having an encapsulated portion enclosed in the fusible layer so as to be below the upper surface of the fusible layer and an embossed portion protruding from the upper surface of the fusible layer.
Further in accordance with the present invention, there is provided a method of forming a laminated panel with at least a fusible layer and a mesh layer, comprising the steps of: i) heating the fusible layer to fuse a portion of the fusible layer; and ii) pressing only a selected portion of the mesh layer against the fusible layer to provide for the formation of an embossed pattern on the resulting laminated panel.

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to the drawings and, more particularly, to Fig. 1, a lamination process in accordance with a preferred embodiment is generally shown at 10. The process 10 is used to fus,e layers of material (hereinafter product layers) to form a laminated panel, using process layers to facilitate the process and obtain effects, such as embossing, in the laminated panel.
Referring to Fig. 2, a typical assembly of the product and process layers that will be used as a batch in the process 10 is generally shown at 20. The assembly 20 has a pair of antiadhesive sheets 21 between which a remainder of the layers are sandwiched. The antiadhesive sheets 21 are typically fiberglass sheets with both surfaces having an anti-adhesive coating, such as a PTFE coating' (i.e., polytetrafluorethylene). The antiadhesive sheets 21 are process layers, in that they will not be part of the laminated panel.
As shown in Figs. 2 and 4, an embossing die 22 is adjacent to one of the antiadhesive sheets 21. The embossing die 22 may be a flat panel made of a material having a relatively high thermal conductivity. Shapes 22' are defined in the panel and these shapes will outline the embossing in the laminated panel that will be produced by the process 10, as will be described hereinafter. Although a single layer of the embossing die 22 is shown in Fig. 1, it is contemplated to provide.
another embossing die 22 adjacent to the other antiadhesive sheet 21 so as to create embossing on both surfaces of the laminated panel that will be produced by the process 10. In such a case, guiding templates are typically used to ensure that the embossing dies 22 are aligned with respect to one another.
For instance, the embossing die 22 typically consists of aluminum (aluminum plate between 1/16" and 1/2" thickness, as a function of the desired embossing), in which shapes have been defined using laser or abrasive jet cutting,.techniques. Other materials, such as metals and high thermal conductivity materials, can also be used to constitute the embossing die 22. A
coating . may be applied on the embossing die 22, to reduce adherence of the product layers 23 to the embossing die 22. The embossing die 22 is also part of the process layers, as it will not be part of the laminated panel.
As shown in Fig. 2, product layers 23 are positioned between one of the antiadhesive sheets 21 and the embossing die 22. The product layers 23 will be fused so as to become the laminated panel, with process layers (i.e., the antiadhesive sheets 21 and the embossing die 22) being removed following the embossing process 10 (Fig. 1).
another embossing die 22 adjacent to the other antiadhesive sheet 21 so as to create embossing on both surfaces of the laminated panel that will be produced by the process 10. In such a case, guiding templates are typically used to ensure that the embossing dies 22 are aligned with respect to one another.

Other materials, such as metals and high thermal conductivity materials, can also be used to constitute the embossing die 22. A
coating . may be applied on the embossing die 22, to reduce adherence of the product layers 23 to the embossing die 22. The embossing die 22 is also part of the process layers, as it will not be part of the laminated panel.
As shown in Fig. 2, product layers 23 are positioned between one of the antiadhesive sheets 21 and the embossing die 22. The product layers 23 will be fused so as to become the laminated panel, with process layers (i.e., the antiadhesive sheets 21 and the embossing die 22) being removed following the embossing process 10 (Fig. 1).
Referring concurrently to Figs. 1 and 3A, the process 10 has a first Step 11 of superposing the product and process layers into the assembly 20 (Fig. 3A), as described previously.
In Step 12, the product layers 23 are laminated. Step 12 involves positioning the product and process layers in a press 30. The press 30 is then closed on the assembly 20, as shown in Fig. 3B, to apply pressure and heat on the assembly 20, so as to create a fusing reaction between the various components of the product layers 23.
The temperature, pressure and cycle time settings of the press 30 are selected as a function of the, product layers 23 that will be fused into the laminated panel. As will be discussed below, press settings will be described with examples of product layers 23. Once the cycle is over, the assembly 20 is removed from the press 30. , The embossing die 22 will cause some embossing in the product layers 23, in that, the pressure applied to the product layers 23 will be lower where the shapes are defined in the embossing die 22. This will cause the product layer 23 to be thicker 'at the locations, resulting in some embossing in the \product layer 23.
This is illustrated in Fig. 5, in which embossed portions Al of the layer 23 are defined as a result of the process 10.
Referring concurrently to Figs. 1 and 3C, in Step 13, the assembly 20 may undergo a stabilization step in a press 31, in which a pressure is' applied onto the assembly 20, and in which the assembly 20 is cooled to ambient temperatures.
The stabilization step is performed to enable the product layers 23 of the assembly 20 to stabilize into their new fused conditions. As the product layers 23 include various types of materials, such as expanded polymer resins and bonding agents, the product layers 23 may be unstable at the exit of the press 30 in Step 12.
Therefore, Step 13 is provided to enable the product layers 23 of the assembly 20 to stabilize into shape as a whole, according to the desired aspect of the laminated product.
Once more, the temperature, pressure and cycle time settings of the press 31 are selected as a function ioV of the product layers 23 of the assembly 20.
The product layer 23 and the process layers assembly 20 may stay together between Steps 12 and 13.
Therefore, the assembly 20 may be carried as a whole from the press 30 to the press 31. The use of antiadhesive sheets 21 to conceal, a remainder of the assembly 20 facilitates the removal of the assembly from the hot press 30, and its handling toward the cooling press 31 (e.g., using the sheets 21 which overhang the product.layers 23 for grip). Moreover, the antiadhesive sheets 21 generally prevent product layer residues to gather on the plates of the presses 30 and 31, which residues would impede on the efficiency of the presses.
It is pointed out that the material and coating of the sheets should be selected so as not to affect the thermal conductivity of the assembly 20. The presence of the embossing die 22 throughout Steps 12 and 13 helps in producing well defined embossing in the laminated panel.
It is also contemplated to provide a single press, equipped with both a heating system and a cooling system, such that the Steps 12 and 13 take place one after the other in the same press, such that the assembly 20 stays assembled as in Step 11. This satisfies the process in that no alignment is required for the assembly 20 to be cooled after being heated, as is the case if the assembly 20 switches presses (e.g., Figs. 3B and 3C).
In Step 14, the laminated panel is extracted from the assembly 20. More specifically, the process layers, namely the' antiadhesive sheets 21 and the embossing die 22 are separated from the product layers 23. The fused product layers 23 define the laminated panel of the preferred embodiment. The process layers are then reusable for subsequent cycles of the process 10.
In Step 15, the laminated panel is cut in pieces, according to intended use of the laminated panel. For instance, boot quarters may be cut following the outline created by the embossing. Moreover, items such as eyelets, trademark logos and decorative materials may be added to the pieces of laminated panel.
It is contemplated to provide curved press surfaces and embossing die 22, so as to shape the product layers 23 with curvature.
It is pointed out that conveyors may be provided, as shown in Figs. 3A to 3C, whereby the displacement of the assembly 20 in the process 10 may be automated.
The product layers 23 may include various materials, according to the type of panel that is desired. As shown in Fig. 2, the product layers 23.
include an external layer 23A, core layers 23B and an internal layer 23C.
The external layer 23A will constitute one of the exposed layers of the laminated panel. Accordingly, the material constituting the external layer 23A will be chosen as a function of the intended use of the laminated panel. For instance, the external layer 23A
In Step 12, the product layers 23 are laminated. Step 12 involves positioning the product and process layers in a press 30. The press 30 is then closed on the assembly 20, as shown in Fig. 3B, to apply pressure and heat on the assembly 20, so as to create a fusing reaction between the various components of the product layers 23.
The temperature, pressure and cycle time settings of the press 30 are selected as a function of the, product layers 23 that will be fused into the laminated panel. As will be discussed below, press settings will be described with examples of product layers 23. Once the cycle is over, the assembly 20 is removed from the press 30. , The embossing die 22 will cause some embossing in the product layers 23, in that, the pressure applied to the product layers 23 will be lower where the shapes are defined in the embossing die 22. This will cause the product layer 23 to be thicker 'at the locations, resulting in some embossing in the \product layer 23.
This is illustrated in Fig. 5, in which embossed portions Al of the layer 23 are defined as a result of the process 10.
Referring concurrently to Figs. 1 and 3C, in Step 13, the assembly 20 may undergo a stabilization step in a press 31, in which a pressure is' applied onto the assembly 20, and in which the assembly 20 is cooled to ambient temperatures.
The stabilization step is performed to enable the product layers 23 of the assembly 20 to stabilize into their new fused conditions. As the product layers 23 include various types of materials, such as expanded polymer resins and bonding agents, the product layers 23 may be unstable at the exit of the press 30 in Step 12.
Therefore, Step 13 is provided to enable the product layers 23 of the assembly 20 to stabilize into shape as a whole, according to the desired aspect of the laminated product.
Once more, the temperature, pressure and cycle time settings of the press 31 are selected as a function ioV of the product layers 23 of the assembly 20.
The product layer 23 and the process layers assembly 20 may stay together between Steps 12 and 13.
Therefore, the assembly 20 may be carried as a whole from the press 30 to the press 31. The use of antiadhesive sheets 21 to conceal, a remainder of the assembly 20 facilitates the removal of the assembly from the hot press 30, and its handling toward the cooling press 31 (e.g., using the sheets 21 which overhang the product.layers 23 for grip). Moreover, the antiadhesive sheets 21 generally prevent product layer residues to gather on the plates of the presses 30 and 31, which residues would impede on the efficiency of the presses.
It is pointed out that the material and coating of the sheets should be selected so as not to affect the thermal conductivity of the assembly 20. The presence of the embossing die 22 throughout Steps 12 and 13 helps in producing well defined embossing in the laminated panel.
It is also contemplated to provide a single press, equipped with both a heating system and a cooling system, such that the Steps 12 and 13 take place one after the other in the same press, such that the assembly 20 stays assembled as in Step 11. This satisfies the process in that no alignment is required for the assembly 20 to be cooled after being heated, as is the case if the assembly 20 switches presses (e.g., Figs. 3B and 3C).
In Step 14, the laminated panel is extracted from the assembly 20. More specifically, the process layers, namely the' antiadhesive sheets 21 and the embossing die 22 are separated from the product layers 23. The fused product layers 23 define the laminated panel of the preferred embodiment. The process layers are then reusable for subsequent cycles of the process 10.
In Step 15, the laminated panel is cut in pieces, according to intended use of the laminated panel. For instance, boot quarters may be cut following the outline created by the embossing. Moreover, items such as eyelets, trademark logos and decorative materials may be added to the pieces of laminated panel.
It is contemplated to provide curved press surfaces and embossing die 22, so as to shape the product layers 23 with curvature.
It is pointed out that conveyors may be provided, as shown in Figs. 3A to 3C, whereby the displacement of the assembly 20 in the process 10 may be automated.
The product layers 23 may include various materials, according to the type of panel that is desired. As shown in Fig. 2, the product layers 23.
include an external layer 23A, core layers 23B and an internal layer 23C.
The external layer 23A will constitute one of the exposed layers of the laminated panel. Accordingly, the material constituting the external layer 23A will be chosen as a function of the intended use of the laminated panel. For instance, the external layer 23A
may consist of fabrics, such as polyester and/or nylon fabrics.
Alternatively, the external layer 23A may be a combination of layers. For instance, to enhance the embossing of the laminated panel, a combination of a mesh layer and a fusible polymeric layer [e.g., polypropylene or polyethylene base material or coating, such as a thermo-plastic olefin (TPO), SurlynTM 8940, with a thickness of 0.040"] is typically used with the lo process 10. In such a case, the mesh layer (e.g., nylon monofilament meshing, with color coating) will be enclosed in the fusible polymeric'layer in areas without embossing, while being exposed at embossing portions.
In addition to creating a visual effect, the mesh embossing will reinforce the laminated panel. On the other hand, the laminated panel remains relatively flexible, whereby it may be shaped/conformed into various products. One type of mesh layer that may be used in the process 10 is a 355D nylon 6 monofilament (diameter of 0.008"), with 800D nylon mono-ply.
The core layers 23B typically include reinforcement materials having a temperature reactive bonding agent, used to reinforce the fabrics and to bond the external layer 23A to other layers of the core layers 23B. The reinforcement materials typically consist of synthetic fiber base materials, such as a non-woven fabric made from a blend of synthetic fibers and impregnated with a filled styrene copolymer with EVA
hot melt adhesive. The bonding agent is preferably activated at a given temperature, such as an EVA glue (ethylene-vinyl-acetate).
A core material of the core layers 23B is typically present, and is fused to the external layers 23A by the reinforcement materials. The core material may be an expanded polymer, such as expanded polypropylene (EPP), expanded polyethylene (EPE), expanded polystyrene (EPS), or similar polymeric foams.
The density and thickness of such foams varies according to the type of laminated panel desired. Other types of core material include papers, cardboard, fabrics,, wood and the like. As an example, some laminated panels have a core of EPP having a density ranging between 2.5 and 5.5 lb/in3, with a thickness ranging between 0.188" and 0.280", for given applications. It is contemplated to use cores 'of other densities and/or thickness in accordance with the contemplated application of the laminated panel.
Another layer of reinforcement material may then be provided in the core layers 23B, to further, reinforce the laminated panel. It is pointed out that the reinforcement material may consist in predefined shapes that will cause an embossing effect in a surface of the laminated panel.
The internal layer 23C will constitute an exposed surface of the laminated panel. For instance, when the laminated panel is used as a boot quarter, this surface will constitute an interior of the boot.
Accordingly, it is contemplated to use a fabric, such as a polyester, as the internal layer 23C. A suitable,type of polyester that may be used as the internal layer 23C
is a 100% brushed polyester (e.g., 1.96 oz/yd2).
It is pointed out that similar materials, and additional layers, may be added to define various configurations of the laminated panel. For the above described materials, suitable fusing results have been obtained heating the press 30 (Fig. 3C) to about 170 C
(e.g., 172 C) with a 4 Psi pressure applied to the assembly 20, for a cycle of 120 seconds in the press 30, to compress a 0.40" of product layers 23 to below 0.37".
The stabilization of Step 13 subsequently took place for another cycle of 120 seconds at pressure of 4 Psi in the cooling press 31, to compress the 0.37" of product layers 23 into the laminated panel of 0.25" of thickness. The temperature of the plates of the press 31 were initially below 16 C, and generally maintained thereat throughout stabilization in Step 13.
As mentioned previously, the temperature, pressure and cycle time settings are dependent on the materials being used, the thickness of the product layers 23, and their capacity to keep their laminated shape following the process 10, and the thickness of the 1o process layers (e.g.; embossing die 22). ' The above values ate given for illustrative purposes. For instance,~ although the cycle time for the Steps 12 and 13 is the same in the above examples, these cycle time values are independent from one another, and it may be 15 that the stabilization cycle is longer to ensure the embossing keeps its shape.
Referring to Figs. 2 and 4, the thickness of the embossing die 22, in relation to the other factors of the lamination process 10, may have an effect on the 20 surface texture of the laminated panel. More specifically, a greater thickness of the embossing die 22 (e.g., 1/4" and more), will result in thicker air pockets between the press plates and the product layers 23. opposite the shapes 22'. As air acts has a thermal 25 insulator, heat from the press 31 is transferred to a portion of the layer 23A that is in contact with the material of the embossing die 22, whereas the shapes 21' encapsulate air such that the portion of layer 23A-opposite the shapes 21' is subjected to lower 30 temperatures and can thus react differently.
Therefore, the thickness of the embossing die 22' is factored in when specific surface texture is required, such as the embossing using a mesh that will be partially encapsulated in a fusible polymeric 35 material. Mesh will show opposite the shapes 21', whereas a lustered polymeric material will encapsulate the mesh opposite the material of the embossing die 22.
Amongst the various possible uses of the laminated panels are the sporting goods industry (quarters for sport shoes/boots, bobt quarters for skate boots, padding for various sports, such as shoulder pads, chest protectors, back pads, rib pads, thigh pads, helmet components, playing surfaces), the clothing industry (boot quarters, e.g., military boots), the furniture industry (cushions, seat backrests, wall partitions), the packing industry and the automotive industry (door inner shell, arm rests, decorative components).
It is within the ambit of the present ls invention to cover any obvious modifications of the embodiments described herein, provided such modifications fall within the scope of the appended claims.
