초록 ▼

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.

A process for the production of a cushion element having a covering material enclosing same, by means of molding in a mold comprising first and second mold portions each having apertures for applying suction thereto, said mold having a mold-open position and a mold-closed position in which a mold cavity is provided to which suction can be applied through said apertures, said process comprising: (a) clamping said covering material with edge portions thereof between first and second clamping frames such that a space is defined within said covering material, with said edge portions thereof projecting beyond said mold cavity; (b) clamping said clamping frames between said mold portions, said mold portions cooperating with said clamping frames to define said closed mold cavity; (c) applying a reduced pressure to said mold portions to draw by suction said covering material into contact with the inside surfaces of said mold cavity; (d) introducing a foamable reaction mixture into said mold and into said space within said covering material through a feed opening which passes through at least one of said clamping frames, between said edge portions of said covering material; and (e) opening said mold portions and said clamping frames after reaction of said reaction mixture for release of said cushion element therefrom.
