Abstract
A method for producing an adhesive fastening element made of plastic includes a support part (10) from which project a plurality of stem parts (12). A head part (14) is arranged at each stem part opposing the support part (10) and the head parts (14) are formed without the use of molding tools due to the surface tension of the used plastic material. Consequently, no need exists for a specific molding tool for forming the head parts.
Claims18
A method for producing an adhesive fastener, comprising the steps of:
- molding stem parts on a support part in a mold with a molding tool extending between the support part and ends of the stem parts remote from the support part;
- forming a head part on each of the ends of the stem parts remote from the support part free of molding tools as a result of surface tension of plastic material used to form each head part;
- and
- removing the molding tool from the mold and after molding of the stem parts in a mold removal process.
1 more element
A molding device for producing an adhesive fastener, comprising:
- a first mold tool having a mold cavity therein;
- and
- a second mold tool placed within said cavity with a support part for the adhesive fastener located between a bottom of the mold cavity and the second mold part, with stem parts of the adhesive fastener extending from the support part through the second mold tool, and with head parts on ends of the stem parts remote from the support part formed by surface tension of plastic material forming the head parts, and second mold tool being a film.
