Method of rolling folded membrane sheeting with preapplied seam tape

Abstract

Membrane sheeting with preapplied seam tape is rolled up by applying the seam tape along a first edge and folding a second edge of the membrane on itself so that it merely abuts an inner edge of the seam tape but does not overlap the seam tape. This forms a folded sheet which has a uniform thickness across its entire width. This can then be rolled in the standard manner to form a roll which has a uniform diameter throughout.

We claim:  
     
         1 . A method of rolling a membrane sheet having a seam tape applied along one edge of said membrane sheeting comprising 
 folding a second edge of said membrane sheeting over upon itself to form a folded sheet wherein said second edge does not overlie any area of said membrane sheeting having seam tape adhered thereto, and    rolling said membrane sheeting.    
     
     
         2 . The method claimed in  claim 1  wherein said seam tape is on a first surface of said membrane sheeting and said second edge of said membrane sheeting is folded onto said first surface.  
     
     
         3 . The method claimed in  claim 1  wherein said seam tape is on a first surface of said membrane sheeting and said second edge of said membrane is folded onto a second surface of said membrane sheeting.  
     
     
         4 . The method claimed in  claim 1  wherein said membrane sheeting is EPDM.  
     
     
         5 . A roll of membrane sheeting having a first edge and a second edge, a seam tape adhered to said first edge wherein said second edge is folded toward said first edge and wherein said second edge does not overlie said seam tape.
