ABSTRACT:
A high speed hopper fed trim saw. The saw includes a first cutting station where a miter cut is made in a trim board and a second cutting station where a kerf cut is made in the same board. Boards are discharged one at a time from the hopper onto a stepped base member, and are moved one at a time from the hopper discharge area of the base member to the first cutting station by an indexing mechanism. After the first cut has been made in the first board to leave the hopper discharge area, the indexing mechanism advances the board to the second cutting station and simultaneously delivers a second board to the first cutting station from the hopper discharge area. Subsequent cycles of the machine simultaneously advance the leading board from the second cutting station to a collection area and the following board from the first cutting station to the second cutting station and the board following it from the hopper discharge area to the first cutting station and so on. The steps formed in the base member are provided to cause each board to fall a first time as it enters the first cutting station, and to fall a second time as it enters the second cutting station. At both stations, roller members control the fall to some extent and urge the board in a rearward direction into a corner defined by that station's step to hinder movement of the board during the cutting operation.
