ABSTRACT:
Method for treating bands of heated non-vulcanized rubber for handling upon removal from a rolling mill which includes the formation of a web of material, and the severing of the web along lines parallel to the web axis to form processing strips. The web is initially formed having a width substantially equal to an integral multiple of process strips, and thereafter the web is partially slit longitudinally along a substantial portion only of the length to provide a plurality of strips, each of the strips being coupled together across a transverse header arranged integral with each of the strips for facilitating handling. The technique is particularly adapted for treatment of the heated non-vulcanized rubber prior to the passing of the material through a cooling tunnel preparatory to storage.
