PROCEDURE FOR THE MANUFACTURE OF FOAM PADS OF AT LEAST TWO FOAMY MATERIALS, ESPECIALLY FOAMY POLYURETHANE MATERIAL, FORMING DIFFERENT ELASTICITY OR HARDNESS, FLOWABLE, CORRESPONDING TO THE DIFFERENT REACTION MIXTURES

摘要

1. A process for the production of foam cushions from at least two flowable, different reaction mixtures forming foams, particularly polyurethane foams, of correspondingly different elasticity or hardness, a first reaction mixture and at least one other reaction mixture being introduced into a mold cavity where they are left to react out to form a cushion having zones of different elasticity of hardness before the cushion is demolded, characterized in that one of the two reaction mixtures is only introduced into the mold cavity when it has acquired a creamed, already viscous consistency and in that the second, non-creamed reaction mixture is introduced at the earliest at the same time.
