Patent ID: 8096552

Claim:
An apparatus, comprising: a belt support system for partially wrapping a continuous belt on a belt drive roller, the belt support system comprising: a first belt support roller at an upstream side of the belt drive roller; and a second belt support roller at a downstream side of the belt drive roller, wherein the first and second belt support rollers are configured to wrap the belt partially on the belt drive roller directly between the first and second belt support rollers; a first frame member and a second frame member pivotably connected to the first frame member, the first belt support roller rotatable mounted on the second frame member at a first location and the second belt support roller rotatably mounted on the first and second frame members at a common second location, the common second location forming a pivot axis for pivoting the second frame member relative to the first frame member, and a system for moving the first belt support roller from a first location relative to the belt drive roller to a second different location, based upon a predetermined load of the belt on the first belt support roller, to thereby reduce an amount of wrap of the belt on the belt drive roller and reduce a length of the belt proximate to the belt drive roller between the first and second belt support rollers.
