Definitions

  • the present invention relates to a plastic material and a method for making the same.
  • the plastic material is particularly a cellular plastic, for example, a closed- cell plastic, from which various paddings, impact absorbers, or flotation materials and similar are made.
  • the present invention is intended to improve both the product and its method of manufacture.
  • a product is achieved, which is less sweaty than before, with perforations that can be easily cleaned by means of the method according to the invention.
  • Figure 2 shows the same material in a state in which the cut-away inner parts of the holes are being removed.
  • Figures 1 and 2 are self-explanatory. Annular cuts, the interiors 2 of which form cylindrical pieces that must be removed to form a hole, are stamped or otherwise made in a sheet-like material 1. Of course, the shape of the piece to be removed can be some other than that of the circular hole shown. According to the invention, removal is assisted by making a cut 3 on at least one side of hole 2 being formed, though if desired a cut can be made on both sides of the hole.
  • Figure 2 shows how cut 3 is opened by spreading material 1 to the sides, providing free space for the cutaway interior 2 of the hole, which can be easily removed by shaking or, for example, using compressed air.
  • interior 2 may drop out with no mechanical assistance at all.
  • its electrical properties may make it cling to the edge of spread cut 3, from which it can be easily detached by, for instance, using compressed air.
  • the hole to be formed can in principle be any shape whatever. If it is wished to use the method to form decorative holes, it will work quite as well as for round holes. Cuts 3 may be on either or both sides of the holes and may run in a direction other than the longitudinal direction of the piece of material. In they run transversely, stret- ching must take place longitudinally. Slanting cuts 3 will function in the said manner without difficulty.
  • a product manufactured according to the invention is suitable for any use, in which, for example, it comes in contact with or close to the skin, when its sweatiness will become an important factor. Breathability can be improved by using slits in addition to perforations.

Abstract

L'invention concerne une matière pouvant servir de matériau (1) pare-chocs, chauffant, de flottabilité, de garnissage ou analogue, constituée d'une substance de base en plastique, en particulier en plastique alvéolaire, dotée de trous permettant de réduire son ressuage ou destinés à d'autres fins. Selon l'invention, les trous (2) présentent au moins une entaille (3) qui permet d'étaler le trou/l'entaille. L'intérieur (2) des trous, qui a été découpé mais qui est resté en place, peut être aisément détaché par étalement du matériau, la partie découpée tombant alors d'elle-même, ou par une opération mécanique appropriée, par exemple par soufflage à l'air comprimé.
