Patent ID: 6840878

Claim:
A tensioning assembly for providing releasable tensioning to a processing belt associated with a wheel assembly of a processing machine, the idler assembly comprising: a fluid distributor adapted to be releasably coupled to a coolant system of the processing machine; the coolant system operative to selectively provide coolant to said fluid distributor; an idler arm pivotally attached at a first end thereof to said fluid distributor; an idler coupled for rotation to a second end of said idler arm; an actuator operatively coupled to said idler arm; and a fluid conduit in fluid communication between said fluid distributor and said actuator; said actuator having a first mode of operation wherein said idler provides an untensioned state to the processing belt, said first mode of operation corresponding to absence of coolant being provided to said actuator from said fluid distributor via said fluid conduit, and having a second mode of operation wherein said idler provides a tensioned state to the processing belt, said second mode of operation corresponding to provision of coolant to said actuator from said fluid distributor via said fluid conduit whereby said actuator causes said idler arm to pivot moving said idler against the processing belt.
