Upgraded Sheeting Winder for TPO, PVC and EPDM Roofing Membranes

 

 

 

Macro Engineering & Technology Inc. has upgraded its heavy sheet winder offering used primarily in the production of roofing membranes comprised of TPO, PVC and EPDM.

To increase production output the winder’s automatic roll transfer sequence has been shortened from 75 seconds to 50 seconds, allowing the extrusion line to operate 50 percent faster.  In addition, the winder can now accommodate finished rolls from 200 mm to 700 mm in diameter and up to 3.5 m wide.

The winder features straight cuts with accurate roll length and new roll starts by means of a tucking mechanism that eliminates the use of glue, tape or staples to fix the sheet onto the core. 

 

The winder is also equipped with a slitting station for creating multiple rolls and an accumulator that provides two minutes of contingency time during process changeovers, sample cuts and routine maintenance.  The finished rolls are taped with automatic taping heads before being unloaded with an automatic roll cart.  New cores are loaded on the winder automatically.

 

Macro built its first TPO winder in 2006 and has since installed several winders throughout North America.
