The different sizes of the two drive rolls can be accomplished by at least three methods. In the first method, one of the two rolls includes a first wedge shaped collar fixed to the shaft and a second wedge shaped collar that is adjustable axially along the shaft. The wedges of the first and second collar form a groove therebetween. A collet is located over grooves of the collars. As the second collar is moved toward the first collar the collet expands.

In the second method, an o-
