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.

Dependent claims

A process for the production of a foam-backed cushion portion comprising a cover enclosing the cushion portion all around, the cushion portion having a front side and a rear side, wherein a cover portion for providing said cover of a generally sock-like configuration having a first open end and a closed oppositely disposed second end is arranged over a generally blade-like mold portion such that a cover portion surface, which forms an outside surface of the cover, is turned over inwardly so that said surface of the cover portion is toward the mold portion, wherein a foam backing is then applied to the cover portion by foaming on a first side of the mold portion to provide a first side of the cushion portion, and a foam backing is applied to the cover portion by foaming on a second side of the mold portion which is in an opposite relationship to said first side thereof to provide a second side of the cushion portion, and wherein thereupon the cover portion with its foam backings is removed from the mold portion and turned inside out such that the foam backings provide a foam core in the interior of the cover portion.
