Abstract
Improvements in molds with multiple stamps intended for the manufacture in series of plastic objects during molding on a band of moldable material subjected to the effects of heat and pressure characterized by the fact that in order to reduce the effort that has to be applied on the dies to exert the mold pressure surface of the working face of at least one matrix is reduced by forming contracted surfaces on the work surface.
