BMW 2 Dual Pivot - Black Magic Series

The BMW 2 Dual Pivot is engineered for stretch film applications of 4.3 and 4.8 meters (14 and 16 ft.). This machine series is a cost effective solution incorporating a single turret assembly compared to other machines which utilize two separate turret assemblies. The winding system is a modular design incorporating the roll changer, turret, PLC, and indexing servo controller into one package providing easy installation and stable operation at high line speed. The dual pivoting shaft design allows for manual roll removal or optional automatic roll removal and re-coring on the 4.3 meter (14 ft.) configuration allowing for 50- second cycle times on hand wrap applications. Both configurations can be mounted on linear slides allowing the winder to side shift for slit lane width changes.
