ABSTRACT:
A method for forming rubber slugs of precisely determined masses. The method embodying the instant invention may be performed utilizing a machine characterized by a stripper unit which serves to extract a continuous, uniformly dimensioned strip of rubber from an endless sheet provided about a roller of a rubber mill, a platen roller, disposed adjacent to the rubber mill and driven at a substantially constant angular velocity, adapted to receive the strip in an adhering relationship for tensioning the extracted strip and a reciprocating knife for transversely severing the tensioned strip into slugs of predetermined lengths, whereby the mass of each of the resulting slugs is precisely determined.
