Methods of processing uncured rubber and like raw materials, and article therefor

Abstract

Abstract The processing of uncured rubber or like raw material, which is normally produced, stored and shipped in sheet form but which is to be subjected to a continuous and uniform strip feeding into an extruder, mill or like treating apparatus, is disclosed. For this purpose, there is provided in a sheet of such material a plurality of slits extending across the sheet and spaced from each other longitudinally of the sheet, the slits in an alternating sequence starting at the opposite side edges of the sheet and each terminating short of the respective other side edge of the sheet. When one end portion of the slit sheet is introduced into the bite of the apparatus, the sheet is subjected to a pulling force and separates along the slits into a continuous zig-zag strip. Apparatus for slitting the sheet in the indicated manner is also disclosed. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
