Abstract
Abstract A belt idler pulley support arm (32) is mounted on a support wall by a pivot structure (48) whose position is determined by three individually adjustable mounting members (71, 72, 73). The mounting members (71, 72, 73) for the pivot structure (48) are accessible for adjustment from the side of the pivot structure remote from the support wall (46) and adjustments may be made while the belt (36) is running thereby allowing a very accurate alignment of the idler pulley (31) with the belt (36).
