When unwinding some low-tack and adhesive rolls the material being unwound can remain stuck to the parent roll longer than is helpful to the overall process. This can lead to a running web either gaining too much tension or temporarily losing tension. This problem is solved by including a peel-off roller near the unwind/master roll, which will hold the unwinding web of material at a constant and acute angle to ensure that correct tension is maintained. A peel-off roller sometimes works in conjunction with a nip roller, which is used to isolate tension between two points on a web path.
