<p>A machine for the automatic preparation of proportions of different caoutchouc blocks for filler mixtures in rubber manufacture has conveyor lines for the different kinds of caoutchouc block, each including a measuring conveyor and a block-weighing conveyor. A movable band saw cuts off portions of the blocks projecting from the measuring conveyors whilst the latter are stationary, and a storage unit disposed downstream of the conveyor lines stores excess portions of blocks severed in one measuring to deliver them to a collector conveyor during a successive cycle, under control of a processor which memorises the required weights of the different kinds of caoutchouc and controls the conveyors, the cutting unit and the storage unit in dependence upon the stored data and data sent to it by the blockweighing conveyors to give the required proportions.</p> |
