Claims6
Apparatus for performing a manufacturing operation on a work piece comprising:
- a first roller rotatably mounted in a support means;
- a second roller rotatably mounted in a support means;
- means for imparting rotation to said first roller and said second roller, said means for imparting rotation to said first roller and said second roller including a first drive element for imparting rotation to said first roller, a second drive element for imparting rotation to said second roller and means for imparting rotation to said first and second drive elements, and wherein the axis of rotation of said second drive element is displaced from the axis of rotation of said second roller;
- means for connecting said second drive element to said second roller for transmitting rotation from said second drive element to said second roller;
- and
- means for mounting said second drive element such that the axis of rotation of said second drive element is displaceable along an arc the center of which is the axis of rotation of said first drive element, whereby displacement of the axis of rotation of said second drive element causes relative rotation of said second roller with respect to said first roller.
