Abstract
A method produces a shaped foam body, especially a foam padding unit for a vehicle seat. At least one adhesive closure with adhesive elements is housed in a recess of a foaming mold used for producing the shaped foam body and is covered with a covering element inhibiting foaming. The covering element is placed on the side opposite to the adhesive elements to extend from the recess over a predetermined width, and is maintained by a holding device, while being removably held against the parts of the foaming mold which surround the recess.
Claims11
A method for producing a foam body part having at least one adhesive closing part with adhering elements, comprising the steps of:
- arranging an adhesive closing part in a foaming mold for forming a foamed body part, the adhesive closing part having first and second opposite surfaces and having adhering elements extending from said first surface;
- protecting the adhering elements on the adhesive closing part against penetration of foam by arranging a foam-inhibiting covering on said second surface of the adhesive closing part to be remote from the adhering elements, the foam-inhibiting covering having a predetermined peripheral border width overlapping and extending beyond a surface area of the adhering elements;
- and
- bringing the foam-inhibiting covering into detachable contact with parts of the foaming mold by permanent magnets in parts of the foaming mold attracting a ferromagnetic coating with ferromagnetic substances admixed therein extending on the foam-inhibiting covering, the permanent magnets being placed laterally about a periphery of a portion of the foaming mold receiving the adhering elements of the adhesive closing part to cooperate with the peripheral border of the covering overlapping the surface area of the adhering elements.
