ABSTRACT:
Bag strips, filled with dosed portions of the substance to be packages, are fed continuously into the machine and the bags are formed solely by folding operations and closed by staples. A series of manufacturing units are continuously circulated along a conveyance path from a initial station, at which a thread-tag strand is fed to the machine and the bag strips are fed to the machine, past stations in which the bags are folded, erected, provided with a top closure, flattened and removed after separation from the strip. Each unit includes a common supporting frame mounting thereon, for conjoint movement along the conveyance path, all the unit devices for folding, closing and separating the bag from the strip, and including raising arms, one of which has a pocket for receiving a tag, a fold plate movable transversely to the bag strip and associated, for forming the bag bottom, with clamping holders movable opposite thereto, a device for cutting a tag thread, folders for forming the V-shaped top closure of the bag, a device for further folding and finishing the top closure and a device for fastening the thread to the bag top. Operating and control means mounted outside the conveyance path at stationary locations control the operation of all of the devices mounted on each common supporting frame.
