Japanese Patent JPS5466987
Kind Code:

Abstract:
A machine for cutting up lumps of crude rubber (synthetic or natural) and weighing out an accurate quantity to be fed to a mixer in accordance with a selected formula, comprising two band saws having special blades with teeth having no "set" and lying entirely within the plane of the blades; crude rubber blocks are fed to a first of two band saws on two conveyor belts which pass one to either side thereof, one of the two conveyors being laterally displaceable and able to convey one of the portions into which the block of crude rubber is cut by the first band saw to be cut by the second band saw, the lateral position to which this portion is conveyed determining the relative size and therefore weight of the two pieces into which this portion is cut; all the cut portions and pieces are fed to an output conveyor which feeds them selectively to a hopper under the control of an automatic weighing machine.
