The invention relates to a method and an apparatus for manufacturing, filling and closing of reclosable plastic bags formed of a bag blank (4) provided with a closing member extending along the entire blank in the shape of two mutually fitting groove and rib profiles (13a, 13b). The bag blank is, before and behind a filling station (II), advanced forward hanging in the pressed together groove and rib profiles (13a, 13b). The bag blank is before the filling station (II) provided with transverse joints (29), which end a short distance form the longitudinal closing member and define separate bags. Each of the groove and rib profiles is during the passage of the filling station (II) hanging separately and guided by each an arcuate path away from each other and back towards each other such that, the groove and rib profiles are reclosed at the top of the filled bags at the same time as the transverse joints are completed to and across the groove and rib profiles and the bags are severed. |
