ABSTRACT:
A circular rotatably driven knife assembly for cutting strips including a carriage for supporting the cutting knife and drive means for the carriage and knife. The knife structure has particular utility for cutting strips of vulcanized rubber such as the tread material adapted to be bonded to the outside of a tire casing, the knife having abrasive grits bonded to its side walls adjacent its periphery to buff the ends of the strip simultaneously with the cutting operation to condition the ends cut off of the portion of the strip for splicing during the vulcanizing step after the severed end of the strip has been wrapped around the tire with the ends pressed into contact with each other.
