ABSTRACT:
A machine with an open upstanding frame has a central space within which a stack of tires are placed. A hydraulic ram mounted on top of the frame, when retracted, supports a press platen slidable on vertical frame posts above the stack and a knife platen spaced above the press platen. Four tire-slitting knives project downwardly from the knife platen in alignment with slots in the press platen. When the ram extends, the knife and press platens move downwardly until the press platen engages the stack. Thereafter continued extension of the ram causes compression springs between the platens to contract so that the knife platen continues downwardly until it engages the press platen and the knives pass through the slots of the press platen into cutting engagement with the stack. Thereafter the knife and press platens continue downwardly together simultaneously compressing and slitting the stack. When the stack is fully compressed and slit through, aligned radial slots in the press platen, in a stationary base plate supporting the stack and in a centering spool on the base plate enable tying of the compressed stack into a bale. Upon retraction of the ram, a knife-stripping mechanism enables withdrawal of the slitting knives from the bale before retraction of the press platen.
