Verfahren zur Herstellung eines Produktes mit einer perforierten thermoplastischen Struktur und Perforierungseinrichtung zur Durchführung des Verfahrens

摘要

The perforated thermoplastic compound material comprises at least one first layer (8) and at least one second layer (9) which are joined to one another at least in parts, and are jointly perforated so that the first and second layers form the exterior and the interior of a three-dimensional structure. The material of the first layer has a lower melting point than the material of the second layer. An Independent claim is also included for the perforation apparatus for production of such a material. It comprises an additional roll (4) which is at least partially penetrated by the protrusions (5) of the perforation roll (2).
