ABSTRACT:
The present invention is directed to an apparatus for the production of foam cushions having textile covers by inserting a textile cover into a mold cavity having gates which project into the mold cavity, initially preforming the textile cover by applying a vacuum through holes in the mold cavity such that the textile cover conforms to the contour on both sides of the gates, clamping the textile cover against the gates, further positioning the textile cover such that it conforms to the contours of both the gates and the mold cavity, releasing the clamps and introducing a foam-forming reaction mixture into the mold cavity. The present invention is also directed to a form tool having gates, means for applying a vacuum through holes in the mold cavity in gates and clamping means for clamping the mold cover to the gates.
