Category: Tension Control

Precise unwind tension control sometimes requires brakes with a wide torque range to meet the wide range of materials (tensions) and widths run on a line.  This is further complicated by the larger rolls (coils) to be unwound (uncoiled).  To put this in perspective, a roll with 72″ OD and 6″ core will require a 12:1 decrease in air pressure from start to core.  If…
