<p>A strip coiling machine is disclosed comprising a frame, a mandrel rotatably supported for receiving sheet metal to be coiled thereon, and pairs of rotatable wrapper rolls parallel to the mandrel and cooperable therewith to form the inital wraps of a coil of sheet metal on the mandrel. Each pair of wrapper rolls is supported by a carriage movable transversely of the mandrel axis, and the wrapper rolls each have opposite ends independently supported with respect to the corresponding carriage for adjustment of the position of the opposite ends of the wrapper roll relative to the mandrel. The adjustable support provides for aligning, or intentionally misaligning the mandrel and wrapper roll axes. The mechanism further includes apron members mounted on the carriage and pivotal relative to the mandrel for cooperation with the wrapper rolls and mandrel to form the initial wraps of a coil. The pivot axes of the aprons are adjustable relative to the corresponding carriage to provide for adjustment of the apron face relative to the outer surface of the mandrel.</p> |
