Abstract (en)

[origin: WO2004082938A1] The invention relates to a method for the separation of composites bodies, comprising at least one inner layer or a core of foam and an outer layer, at least partly covering the foam layer or the foam core, made from a textile material, plastic, synthetic leather or leather. According to the invention, a simple separation of the composite bodies, as selective as possible can be achieved, whereby a fluid is applied in the transition region between the inner layer or the core and the outer layer or outer sleeve. The composite body is then subjected to a microwave or ultrasound treatment.
