Heavy duty rewind shafts with optional centre supports. Driven layon rolls add tension to the centre wind tension for excellent winding of larger diameters. The overhead web path keeps the web clean and visible and leaves space below for handling systems to unload the larger diameter rolls. The ALPHATWIN HR is normally supplied with unload trolleys with integrated scissor lifts to quickly move finished rewind rolls to the side of the machine. The open layout is optimised with fully integrated automatic knife setting and laser core loading for fast job changes.
