A zipper segment (34) for transverse direction application to a bag film web (38) in which the profiles (14,16) are of unequal lengths and joined together at their ends. As a result, the shorter profile (16) is placed in tension. During bag formation the longer profile (14) is initially attached to the bag film web (38) and the shorter side (16) is attached only by the engagement of the profile interlocking members and end seals (26). The shorter side (16), which is not directly attached to the web (38), nonetheless remains close to the web (38) as a result of the tension imparted on the short side (16) by the longer side (14). <IMAGE> |
