A simple direct acting mechanism moves a circular rotatable disc cutter or two such cutters first to rollably engage a hard surface and then to traverse the surface to part the stock between a side-by-side pair of cords or wires. The cutter or cutters are blunt edged, as well as unheated and so avoid baring the cords or wires while parting the stock without the undesired effect of sharp or hot knives. The cutter or cutters are shiftable along the axis or axes to accommodate deviation of the cords with respect to the travel of the cutter. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
Apparatus for cutting tire making material having parallel closely spaced cords or wires embedded in uncured rubbery gum, the apparatus comprising frame means, ply stock support means in said frame means having an uninterrupted hard surface for supporting said ply stock, carrier means mounted on the frame means to extend transversely of said support means and mounted for movement toward and away from said support means in parallel relation thereto, carriage means mounted on the carrier means for movement transversely of the support means parallel thereto, swing arm means pivotally mounted on the carriage means to swing in a plane normal to said support means, a cutter shaft carried by the swing arm means, and a single disccutter having a blunt circular edge rollably engageable with said hard surface to part said gum between a side-by-side pair of said cords or wires, said cutter being mounted to rotate freely about the cutter shaft, said cutter being displaceable coaxially of the shaft in response to deviations of said pair of cords or wires relative to the direction of movement of the carriage.
