Abstract
The invention relates to a method for producing a form-cut object made of foam. The invention is based on the aim of refining a known method for producing a form-cut object made of foam in that it also allows the precise creation of complex shaped form cuts in the foam. This aim is achieved by the method according to the invention in that the first preliminary version of the object in the region of a first form or contour cut is provided with a (second) form cut, which is superimposed on the first form or contour cut and extends down to larger depths than the first cut. Preferred application areas of the claimed method and the resultant objects made of foam are pillows, for example.
