ABSTRACT:
A process for manufacturing reclosable bags (30) by forming a film (50) includes moving the film (50) and attaching to the film (50) sequentially and crosswise with reference to the direction of movement of the film (50), a fastener (1) including a first strip (2) supporting at least one reclosable profile (10) engaged with another reclosable profile (12) that is complementary thereto and supported by a second strip (4) or a part of the first strip (2), which will subsequently be attached to the film (50). Each strip (2, 4) includes at least one web (6, 8) extending substantially mostly sideways on one side of the profiles (12). The above arrangements make possible special fasteners (1) that include sliders (9), gasket membranes (26), fasteners inverted within the bag (30), peel seals (18, 20, 21) and hinged fasteners (1).
