ABSTRACT:
A process for making moldings with areas of marked final deformation from highly sensitive materials, such as tangled-fiber fleeces, in which the flat material is molded in the softened state between press molds. Prior to the actual molding process and independent of the desired molding of the final molding in a particular area and without any precompression of the material, the material is mechanically drawn between the corresponding press molds to such an extent that the resulting material flow roughly corresponds to the feed requirement for the final molding operation. The necessary auxiliary device comprises one or more push-rods with ram heads, which can be brought between the press molds when the press is in the open position and can be moved in the desired directions in the manner of an automated human fist.
