<p>Filled bags (14) delivered from a vertical form fill and seal machine (12) are received in holders (18, 218) for conveyance to and through a further processing station (C) in which at least one sealing, cutting, gluing, folding or similar operation is carried out on the bags while in the holders. The holders may comprise sleeve-like elements (15) movable on an endless horizontal path (16, 216). The holders may slide on a stationary support surface (22, 222) and may be independently movable by means of pushers (54) or connected to a horizontal endless chain conveyor (219). In the processing station (C) successive bags may be subjected to a compressing, resealing and trimming operation to allow each bag to be formed with a block top.</p> |
