New Reversible Surface Winder from Macro

After 30 years of building winders, Macro Engineering & Technology Inc. introduced the latest addition to its family of surface winders, the AUTOMAX-SBG Reversible Surface Winder

Reversible Surface WindersUnlike traditional gap surface winders that can only wind film in one direction, the AUTOMAX-SBG features a reversible winding mode, which allows the processor to choose whether to wind jumbo rolls with the film’s treated side in or with the treated side out.  The switch between winding directions is uncomplicated; the operator simply needs to thread the film in the opposite direction around the drum and select the appropriate winding direction on the touch screen.  The winder also features straight edge cutovers that are done without fold-over to produce rolls with flat, wrinkle-free film completely to the core.  This allows the converter to utilize the entire roll and save costs from scrap.  Other advantages of the AUTOMAX-SBG are the gap winding mode, programmable tension controls, fully automatic roll transfers, and an integrated shaft hoist that returns the shaft to the loading position without heavy lifting by the operator.  The winder can handle rolls up to 1.5 m (4.9 ft) in diameter and film thickness from 15 to 400 microns (0.6 to 16 mil).  Winding shafts are available in 76 mm (3 inch) and 152 mm (6 inch) sizes.  It will wind materials up to 3 m (9.8 ft) wide at speeds up to 200 m/min (656 ft/min). 

As with other Macro winders, the AUTOMAX-SBG features excellent tension control, simplified operation and requires minimal maintenance.
