Bridle roll diameters are identical for all five entry and five exit rolls: 1,050 mm (41.339") (Polyurethane jacketed) The separate Anti-Coil Break Roll stand has a work roll diameter of 130 mm (5.119") with two backup rolls of 180 mm (7.087") diameter and a separately actuated hold-down roll with 406 mm (15.984") diameter.

With a common DC buss, the energy produced by a regenerating drive, ie: entry bridle drives during line run can be used to power the exit bridle drives thereby significantly reducing the incoming power requirement from the three phase supply. Drive regeneration is used during an Emergency Stop to quickly stop the strip so snubber resistors are supplied to dissipate the excess energy. One AC Drive isolation transformer is included for the new AC Drives. Entry Five Roll Tension Bridle Unit: Tension Rolls: Snubber Rolls: Diameter: 10" Surface: Polyurethane
