ROTARY VENEER CLIPPER A B S T R A C T A rotary veneer clipper has a pair of cutting blades spaced 180° apart on a rotary clipper shaft for cutting cooperation with a roller anvil below and parallel to the clipper shaft and over which sheet material passes. The clipper shaft rotates intermittently on signal to cause one of its blades to clip the sheet. The clipper shaft is driven by a pair of pneumatic drive cylinders mounted one to each of two crank arms connected to a common drive shaft. The cylinders stroke once simultaneously to rotate the driven shaft alternately in opposite directions through 90° upon each successive clip signal. When the drive shaft rotates in one direction, a first gear train transmits power from the drive shaft through a fir one-way clutch to the clipper shaft to rotate one of the blades downwardly and through 180° to clip the sheet. When the drive shaft is rotated in the opposite direction, a second gear train transmits power from the drive shaft to the clipper shaft through a second one-way clutch to rotate the other clipper blade through 180° in the direction of sheet travel to clip the sheet. Locking means including a pneumatic locking cylinder limits clipper shaft rotation to exactly 180° upon each stroking of the drive cylinders to accurately index the cutting blades. An optional blade speed control feature is also provided.
