  • Patent number: 3945285
    Abstract: An upright rectangular frame has a roller conveyor in its lower horizontal member, carries hydraulically operated clamps on its upright members, and movably supports a carrier for a tilting circular saw on its upper horizontal member. A panel of plywood and the like can be cut horizontally into two sections while the lower edge of the lower section rests on the roller conveyor and the upper section is clamped to the frame. The lower section may then be shifted horizontally on the roller conveyor in the original plane of the panel and further divided into parts by vertical saw cuts, whereupon the upper panel section is lowered to the roller conveyor, and the procedure is repeated until the panel is entirely divided into portions of desired size.
