Abstract
A method for producing an adhesive closing element having a plurality of hook elements formed as a single piece with a support. The hook elements are rod-shaped and have enlargements at their ends. A thermoplastic synthetic material is fed into the gap between two moveable tools in a plastic or liquid state. The tools are driven such that a support is formed in the gap and displaced in a direction of conveyance. The hook elements are formed by forming elements acting on the gap. The hook elements are formed on both sides of tile support by the forming elements that are active on both sides of the gap.
Claims16
A method for producing an adhesive closing element having a plurality of hook elements configured unitarily as one piece on a support and having the hook elements being rods with end enlargements, comprising the steps of:
- feeding thermoplastic synthetic resin in a plastic or fluid state into a gap between movable tools;
- driving the tools to form the support in the gap and to convey the support in one direction;
- forming the hook elements on both sides of the support by forming elements operating on both sides of the gap, the forming elements including first and second screens with first and second hollow spaces, respectively, passing entirely therethrough, the second screen being arranged on an interior of the first screen;
- and
- hardening the thermoplastic synthetic resin at least partially in the hollow spaces of the screens.
