METHOD FOR PRODUCING AN ADHESIVE CLOSURE PART, METHOD FOR THE PRODUCTION OF A SHAPING ROLLER AND SHAPING ROLLER
First Claim
1. A method for producing an adhesion closure part with a carrier, a one-piece arrangement with projecting stems comprising hooking elements in a the area of the stems opposite the carrier, in whicha heated, thermoplastic material is supplied to a gap, which is formed by a shaping roller equipped with shaping cavities as well as a counter surface, particularly a pressure roller,the heated, thermoplastic material is inserted into the shaping cavities,the heated, thermoplastic material sets in the shaping cavities,the stems with the hooking elements are removed from the shaping cavities,the carrier with the stems and the hooking elements is continuously pulled off, andthe shaping roller comprises a porous material in the area of the shaping cavities, at least sectional, which ensures air permeability,whereinthe porous material represents a foamed material, sinter material, build-up welded and/or sprayed-on material.

Abstract
The invention relates to a method for producing an adhesive closure part (1) comprising a support (2), a single-pieced arrangement made of projecting stems with hooking elements (4), which are mounted in the region of the stems (3) opposite the support. According to the invention, a heated thermoplastic material is guided to a gap (5) which is formed between a shaping roller provided with shaping cavities (7), and a counter surface, in particular a pressure roller (8), the heated thermoplastic material is introduced into the shaping cavities (7), the heated thermoplastic material solidifying in said shaping cavities (7), the stems (3) with hooking elements (4) are removed from the shaping cavities (7), the support (2) with the stems (3) and the hooking elements (4) is extracted continuously and the shaping roller (6) is made of, at least in the region of the shaping cavities (7), a porous material which ensures air permeability, the porous material is expanded material, sinter material, soldered and/or injected material.
