  • Strip cutter apparatus for rolled sheet formed of rubber
    Patent number: 4116096
    Abstract: A strip cutter apparatus for rolled sheet formed of rubber and elastomeric materials, comprising a transport device for the rolled sheet and a plurality of disc-shaped cutters arranged transversely with respect to the transport direction of the material. The cutters cut the rolled sheet into individual strips. A revolving brush is driven in the direction of transport and is provided after the cutters, viewed in the direction of travel of the rolled sheet. This revolving brush is arranged in such a manner that its bristles penetrate into the intermediate spaces between the cutters and displace away from the sides of the cutters any material which possibly has been raised by the cutters.

  • Method of slitting non-vulcanized rubber web upon removal from rolling mill
    Patent number: 3991151
    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.
