ABSTRACT:
An apparatus for feeding flat, rigid material through a cutter comprising a continuous drive conveyor belt with a non-skid face, having one or more Guide ‘V’ belts bonded to its reverse side parallel to the direction of movement, which ‘V’ belts communicate with corresponding ‘V’ grooves in the power rollers and the rollers of the feed bed, another continuous drive conveyor belt on the out-put side of the cutter, the movement of both conveyors being synchronized by a timing/drive belt which transfers the motor drive to the inside rollers of the out-put and the input sides, and having from above regularly spaced hold-down rollers along the span of both conveyors to keep the rate of movement of the flat material through the cutter consistent. This apparatus has its preferred application in the lumber industry for trimming defects and/or wanes from wood boards, so that the boards maintain consistent position in the horizontal plane while traveling through the cutters.
