ABSTRACT:
Bars of soap, synthetic detergent or mixtures of them are stamped between dies. In contrast with conventional stamping machinery the relative velocity of the dies is made to decrease at a rate which is more than proportional to the decrease in distance between the dies. Preferably the decrease is at a rate which is proportional to the cube of the decrease in distance. The process leads to a reduction in the adherence of soap/detergent to the dies.
