ABSTRACT:
A cut-to-size saw mechanism having a dual, programable control system is provided for large sheet material, as plywood, hardboard, chipboard, fiberboard, and other large panels to be divided into small pieces by sawing. Sheet sizes in the range of 5 .times. 18' can be cut with a main strip or strips and a side, residual strip, with the residual having a maximum width up to a predetermined amount, such as 2'. Where desired, cutting patterns necessitate two asymmetrical patterns, the saw mechanism can be programmed to trim all 4 edges of a panel, divide the panel into main and residual longitudinal strips and cut the main strip or strips in one pattern length and the residual strip in another selected pattern length. All sawing is done while the panels or strips thereof are held by hold-down rolls, thereby assuring precision sawing. All sawing of the entire panel is programmed by thumb switches from a control panel and the same program may be repeated on subsequent panels until the programming is changed.
