Definitions
- the invention relates to a waterproof zipper with the features of the preamble of claim 1 and a method for producing such a zipper.
- Waterproof zippers consisting of two rows of teeth each connected to a zipper band, the rows of teeth being able to be brought into engagement and separated again by means of a slide, and the zippers in the region of the rows of teeth having a sealant which, when the zipper is closed, are in sealing contact with one another. are widely known.
- EP 0 210 632 B1 or DE 37 15 068 show watertight zippers, in which the zipper tape is guided around the teeth, so that the tapes of the two sides lie against one another in the closed state.
- the disadvantage of this design is that it is complex
- the object of the invention is therefore to provide a waterproof zipper which can be easily produced from inexpensive and common types of zipper.
- Another object of the invention is to demonstrate a method for producing such a zipper.
- the sealing means for sealing the closed zipper is an elastic rubber or between the individual teeth
- the plastic material advantageously consists of a thermoplastic elastomer.
- Polyurethane has proven to be particularly useful because of this
- materials such as polyurethane can be easily processed, for example by Attaching end pieces by welding or spraying. Zippers produced in this way can also be easily connected to articles of clothing or bags or coated with, for example, PVC or polyurethane, for example by welding.
- Zipper types can be used. Inexpensive (e.g. by the meter) zippers are advantageously used. It has proven to be particularly advantageous to use simple plastic spiral zippers, since these have good connectivity to the elastic, thermoplastic material and in particular to polyurethane and, secondly, they have inherent elasticity which is advantageous for the method according to the invention.
- the plastic from which the plastic spirals are made is a polytetrafluoroethylene (PTFE), since this is particularly wear-resistant and heat-resistant. Since it may be important for the method according to the invention that the teeth do not stick to the sealant, the repellent properties of the PTFE are also desirable.
- PTFE polytetrafluoroethylene
- this method according to the invention for producing a waterproof zipper consists of the following steps:
- the zipper is fed to a cooling section, with the zipper straps being pulled apart laterally with a force which defines the corresponding tooth tips presses against one another, but does not separate them, which displaces the plasticizing thermoplastic material at the tooth tips between the teeth and puts the zipper under tension, the thermoplastic material between and on both rows of teeth still remaining homogeneously connected,
- the zipper is fed to a braking station and then to a pull-off station, the zipper being passed between the stations over a wedge and being opened continuously, a knife being arranged on or in front of the wedge for severing the thermoplastic material,
- a zipper with zipper tapes is fed into an extruder in the closed state, opened there by a wedge, impregnated with liquefied thermoplastic material, coated and closed again,
- the zipper is fed to a cooling section, the zipper straps being pulled apart laterally with a force which presses the corresponding tooth tips internally against one another in a defined manner, but does not separate them, as a result of which the plasticizing thermoplastic material at the tooth tips is displaced between the teeth and the zipper underneath Preload is set, the thermoplastic material between the two rows of teeth remains homogeneously bonded,
- the zipper is fed to a braking station and then to a trigger station, the zipper is guided between the stations over a wedge and is continuously opened, a knife for severing the thermoplastic material being arranged on or in front of the wedge, - the finished waterproof zipper is closed again.
- a further method according to the invention for producing a waterproof zipper provides the steps:
- the zipper is fed to a vulcanization station, at the same time the
- Zipper bands are pulled apart laterally with a force that presses the corresponding tooth tips against one another in a defined manner, but does not separate them, whereby the rubber on the tooth tips is displaced between the teeth and the zipper is pretensioned, the vulcanized rubber between the two rows of teeth still being homogeneous remains connected, the zipper is fed to a braking station and then to a pull-off station, the zipper being passed between the stations over a wedge and being opened continuously, a knife being arranged on or in front of the wedge for severing the vulcanized rubber,
- the assembled (e.g. by the meter) zipper preferably a plastic spiral zipper
- the assembled (e.g. by the meter) zipper is initially on an unwinding station.
- the zipper tapes can be treated with an adhesive for the thermoplastic material and the tips of the teeth can be coated with a release agent. This preprocessing can be done both before the zipper is inserted into the unwinding station and immediately after
- Unwinding can be done.
- the plastic spirals can also be coated with the release agent before sewing with the zipper tape.
- the closed zipper is fed from the unwinding station to the nozzle of an extruder, the extruder impregnating and coating the zipper with liquefied thermoplastic material, preferably polyurethane.
- Plastic material that is simultaneously fed to a cooling station for example a water bath, is displaced or located at the tooth tips between the teeth not there if the zipper straps are already stretched across before coating.
- the cross tensioning device for pulling the zipper apart consists, for example, of two needle bands, each of which runs around two or more rollers.
- the needle tapes are guided and tensioned. They run almost parallel to each other at a defined angle. Here the opposing needles diverge continuously.
- the needle tapes can be driven or not driven.
- thermoplastic material solidifies in the cooling pool.
- plastic teeth of the two rows of teeth against each other also remain in
- the zipper is continuously fed first to a braking station and later to a pull-off station, whereby a longitudinal tension is achieved.
- a separating and cutting wedge is arranged between the braking and the triggering station, or a separating and a cutting station are arranged.
- the separating wedge opens the zipper continuously over a certain number of teeth, e.g. 1 to 8 teeth.
- the thermoplastic, elastic plastic material is pulled apart and can be separated from a knife which is arranged on or in front of the wedge, without the zipper teeth being damaged.
- the zipper tapes are made with the thermoplastic Plastic material coated and the solidified plastic material fills the area between the individual teeth.
- the zipper was closed again by means of a zipper slide and fed to a take-off station and finally to a winding station.
- the zipper can also be closed after the pull-off station.
- the closed zipper again has a transverse tension, since the interlocking rows of teeth press together the plastic material, which was not reduced by the cutting process.
- the zipper produced by the method according to the invention has so much thermoplastic, elastic plastic material between the individual teeth of its rows of teeth that it is firmly pressed together when the zipper is closed. Since the zipper tape is also covered with the thermoplastic material, a simply manufactured, particularly inexpensive, waterproof zipper is obtained.
