Abstract
A drive device for a two-shaft extruding machine whereby the directions of relative rotation of the two screw shafts of the machine can be rapidly changed without having to manually change a gear. The drive device includes a first shaft, a second shaft disposed coaxially with the first screw shaft and rotatable integrally therewith, a third shaft disposed coaxially with the intermediate shaft and rotatable integrally therewith, a first gear rotatable integrally with the first shaft, a second gear rotatable integrally with the second shaft and meshed with the first gear, a third gear rotatably supported on the third shaft and meshed with the first gear, and a fourth gear rotatable integrally with the second shaft and a fifth gear rotatably supported on the third shaft and meshed with the fourth gear. A claw clutch is provided for rotatably coupling a selected one of the third and fifth gear to the third shaft. An operating mechanism controls the operating position of the claw clutch from a point outside the drive device.
