ABSTRACT:
A method and apparatus for stamping a blank of plastic material, such as a soap blank, into a shaped article, such as a soap bar. The apparatus and method uses a pair of mating die halves spaced apart from one another in order to receive the blank of plastic material. Thereafter, the blank of plastic material is stamped and shaped by closing the die halves so they are mating. The die halves are then opened so as to discharge the shaped article and receive a new blank of plastic material. The present invention contemplates placing an elastomeric septum across each die half between the blank and the die half so as to prevent plastic material from sticking to the die halves after stamping. It has been found that a septum made from latex works well.
