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.
