Abstract Apparatus for cutting veneer strip comprises an infeed conveyor which determines the speed of the strip, a removal conveyor, and a cutter between the conveyors. The removal conveyor is driven at a higher speed that the infeed conveyor, and a control mechanism is arranged above the removal conveyor to sense the speed of material moving along the removal conveyor. If material is travelling along the removal conveyor at the speed of the infeed conveyor, that is if the material on the removal conveyor is still connected to the strip, the control mechanism actuates the cutter. If the material is travelling at the speed of the removal conveyor, that is if the material has been previously cut from the strip, the cutter device is not actuated. The control mechanism is in the form of photocells which sense the leading edge of the material, and a timer actuated by the photocells.
In apparatus for cutting strip materal, a material infeed conveyor, cutter means downstream of the infeed conveyor, a removal conveyor downstream of the cutter means, the removal conveyor being drivable at a higher speed than the infeed conveyor, and control means operative to selectively actuate the cutter means, the cutter means also being actuable independently of the control means, said control means comprising first and second sensor means spaced aLong the path of movement of the removal conveyor and operative to sense material moving along the removal conveyor, and timer means responsive to the sensor means to determine the speed of movement of the material moving along the removal conveyor such that the cutter means is actuated if the said speed is less than a predetermined speed.
