Abstract:
A laterally shiftable roller assembly comprising:a roller; roller journals supporting said roller for lateral shifting and for rotation about a roller axis of rotation; a drive mechanism useable to shift said roller laterally, said drive mechanism having a drive mechanism axis of rotation; a coupler extending between said roller and said drive mechanism, said coupler having a first end connected to said roller journal and having a second end connected to said drive mechanism offset from said drive mechanism axis of rotation wherein rotation of said drive mechanism causes said roller to shift laterally along said roller axis of rotation and further wherein a number of revolutions of said drive mechanisms and a number of revolutions of said roller can be changed in relation to each other; and means supporting said drive mechanism for pivotal movement with respect to said roller axis of rotation to shift said drive mechanism axis of rotation relative to said roller axis of rotation to vary an amount of said lateral shifting of said roller.
