An apparatus for rotationally driving two closely spaced shafts comprises a driven gear on each shaft and two drive apparatus for driving each of the driven gears. The shafts are constrained to rotate at the same speed by interengaging teeth of the driven gears or by an idler gear. Four indpendent motors are used to drive the shafts. If the shafts are not parallel, the driven gears may be conical. Alternatively, the driven gears may be cylindrical, and each shaft may have thereon a conical gear, the conical gears being sized and positioned to mesh.


An apparatus for rotationally driving two closely spaced extrusion shafts at the same speed and in opposite directions, comprising: a driven gear fixedly mounted on each respective shaft; two respective drive gears engaged with the driven gears for directly driving each said respective driven gear; a separate drive means for driving each respective drive gear; each said respective drive means including a motor means; and synchronizing means, secured on each respective shaft, for constraining each of said two closely spaced shafts to rotate at the same sp...
