A slider Fig. 1, for a "rib and groove" type fastener has divergent walls and a spacing element 4 and is made of elastically-deformable plastics material so that it can be fitted to the fastener strips by movement perpendicular thereto. In a process for fitting the slider to a bag Fig. 7, the slider strips 1, 1' pass from electrodes 14, 14', where a folded plastics sheet is welded to the strips over a spacing element 15 provided with guide elements 16, 16' which may act intermittently as clamps, and through clamping and guiding parts 17, 17', the slider 2 being located on the fastener by movement perpendicular thereto. The strips may pass continuously or be periodically stopped for attachment of the slider and welding of the transverse sides of the bag. |
