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.

Abstract: An improved closed chamber baler includes a hopper into which is fed waste paper or other compressible materials to be baled. The material to be baled is forced into a bale chamber by means of a piston operated ram. Means are provided for sequentially guiding a strapping wire about the outside periphery of the compressed material at a plurality of vertically spaced intervals along the compressed material. The strapping wire is tensioned and then twisted or knotted together to form a continuous strap about the compressed material, thereby forming a bale. When the bale has been completely strapped, the compression ram is retracted and an output gate is opened. The bale is then ejected from the bale chamber by an automatic bale ejector. While the invention is disclosed in connection with baling waste paper, the closed chamber baler is capable of other uses, e.g.
