Claim:
A system comprising: a sheet of unvulcanized elastomeric material; and, a liner having a first end, a second end, a width, a length and a longitudinal centerline, the liner comprising: (a) a first portion extending from the first end of the liner to a first transition region in the liner, the first transition region being between the first end and the second end of the liner, the first portion having a length; and, (b) a second portion extending from the first transition region in the liner to the second end of the liner, the first portion of the liner being made of a first material and the second portion of the liner being made of a second material, the second portion having a length, wherein the first portion length is less than the second portion length, wherein the sheet of unvulcanized elastomeric material sticks to the first portion of the liner at a first propensity for sticking, and the sheet of unvulcanized elastomeric material sticks to the second portion of the liner at a second propensity for sticking, the second propensity for sticking being greater than the first propensity for sticking.
