Abstract
A process for the production of a foam-backed cushion portion with a cover covering same on all sides includes turning the cover inside out and applying the cover over a first mold portion of blade-like configuration with its outward surface over the first mold portion, arranged two second mold portions at respective sides of the first mold portion at a spacing therefrom, thereby forming at least one mold cavity between the first mold portion and the second mold portions. A reaction mixture is then introduced into the mold cavity to fill same with foam forming foam backing portions on the cover. The mold is then opened and the foam-backed cover is removed from the first mold portion and turned inside out to provide a foam-backed cushion portion, the cover which was disposed on the inward side of the foam material coming to lie on the outward side of the foam-backed cushion portion.
