Abstract
The invention concerns a method to manufacture fastening assemblies (1) for bags, characterized in that, for each assembly (1), it comprises the steps of supplying interlocking profiles (11) provided with flanges (12) for attachment to a bag; mounting an actuating slider (13) on the profiles (11); forming two end stops (2) for the slider (13) in the profiles (11); forming two lumens (3) in the attachment flanges (12); each lumen (3) having a longitudinal extension (E/2); forming two lines of weakness (4) between each lumen (3) and an upper part (111) of the profiles (11). The invention also concerns a corresponding bag-forming method, a corresponding strip of assemblies, and corresponding bag.
