Abstract
A method for producing a touch-and-close fastener part includes producing a base structure from a thread system having individual loops which are at least partially of a polyamide or polyester plastics material. At least a portion of the loops are cut to form two stem-like loop ends. The loop ends are heated at a predeterminable temperature and for a predeterminable heating time until a head shape is produced as a thickening at the respective loop end under the surface tension of the plastics material. The head shape is formed with a convex upper side which, at the point of a linear transition, merges into a concave interlocking surface which is seamlessly transferred into the adjoining stem-like loop end for an interlocking element.

A method for producing a touch-and-close fastener part, comprising at least the following steps:
- producing a base structure from a thread system comprising individual loops which consist at least partially of a polyamide or polyester plastics material;
- cutting at least a portion of the loops to form two stem-like loop ends;
- heating the loop ends at a predeterminable temperature and for a predeterminable heating time until a head shape is produced as a thickening at the respective loop end under the surface tension of the plastics material;
- and
- forming the head shape with a convex upper side which, at the point of a linear transition, merges into a concave interlocking surface which is seamlessly transferred into the adjoining stem-like loop end for an interlocking element.
