This winder features an integrated automatic core and roll handling system and capabilities for producing six-up rolls on a 25-second cycle time, roll change to roll change. Based on upstream capabilities and 80 percent line uptime, the BMW S4 can produce up to 2,700 roll sets.

The BMW S4 is designed as a four spindle surface/center winder with center core shaft supports. This arrangement in conjunction with continuous, dual-surface-driven lay-on rolls enables production of "flat-tail" film rolls. Flat-tail rolls are wound from the top side of the web (the side against the chill roll) into the roll to produce inline-slit films that are virtually scrap-free from the core to the last wrap for both hand and machine wrap stretch films.
