Abstract
Abstract A letoff truck having wheels for rolling the truck to and from a bias cutter feeder is releasably connected to the feeder for movement of the truck with the feeder during angular adjustment of the feeder for a desired bias angle setting. The truck is also mounted for transverse movement relative to the feeder to compensate for deviations in the position of the edge of the goods conveyed from the letoff truck to the feeder. Adjustment of the feeder angle about a pivot axis to provide the desired bias angle setting is provided by a powered sprocket mounted on the feeder and positioned between idler sprockets. The sprockets are engageable with a chain member extending between the ends of a transverse track on which one end of the feeder is supported by rollers. When the desired feeder position is obtained the feeder may be positively locked in that position.
