Abstract
In a process and apparatus for the production of a cushion element with a cover means enclosing same, at least one cover means is clamped with edge portions thereof between first and second clamping frames in such a way that the cover means defines a space therewithin. The clamping frames with the cover means clamped thereby are then held between first and second mold portions, with the cover means disposed in the mold cavity defined by the co-operation of the clamping frames and the mold portions. The cover means is drawn by suction against the mold cavity surface and a reaction mixture is then introduced into the space defined by the cover means within the mold cavity, through at least one feed opening. After reaction of the mixture the mold portions are separated and the cushion element with cover thereon from the mold. For the purposes of mechanically stiffening and reducing the weight of the cushion element, a member may be disposed within the cushion element, being positioned within the cover means in the mold cavity by means of a connecting member extending beyond the outside contour of the cushion element.
