Abstract

A method of rolling a membrane sheeting having a preapplied seam tape is disclosed. In order to provide a uniform diameter of the formed roll, filler strips are placed along the field portion of the membrane sheeting parallel to the seam tape. This is then rolled up to form a uniformly thick roll of membrane sheeting.

Claims

1. A method of rolling membrane sheeting having a preapplied seam tape along one edge comprising placing at least one filler strip on said sheeting parallel to said seam tape and rolling said sheet whereby said seam tape forms a first edge of a formed roll and the filler strip is rolled simultaneously with said sheeting.

2. The method claimed in claim 1 wherein a plurality of filler strips are placed on said sheeting parallel to said seam tape.

3. The method claimed in claim 2 whereby said filler strips have a thickness equal to the thickness of said seam tape.

4. The method claimed in claim 2 wherein one of said filler strips is positioned along a second edge of said sheeting.

5. A roll of membrane sheeting having a first edge and a field portion, a seam tape along said first edge, a plurality of filler strips in said field portion and along a second edge of said membrane sheeting, said filler strips positioned parallel to said first edge.
