In a web of envelope lengths rolled for storage, adhesives on the web are arranged to not overlap during storage. To prevent the areas of adhesive of the front surface on one turn from binding to the areas of adhesive on the back surface of an adjacent turn in the roll, the transverse lines of adhesion are formed of adhesive spots, and the adhesives on the front surface are contained in first longitudinal zones and the adhesives on the back surface are contained in second longitudinal zones separate from the adhesives on the front surface. This disposition may be a combined arrangement of adhesives which also prevents adhesion when the web assembly is folded in zigzag packet configuration for storage.
