Duplex Slitter Rewinders – heavy duty

The ALPHATWIN HR duplex slitter rewinder for large diameter rewinding with both shafts set at low level for fast and safe unloading, typically used for labelstock or papers.

 

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.
