Rotary Patents (Class 53/253)
  • Patent number: 5199241
    Abstract: A can star drive for a fish-canning machine in which a turret 11 and can star 75 are separately driven, with the can star 75 being rotated through its 120.degree. advance in each cycle during half again as much time as it takes for the turret 11 to advance through its 120.degree. advance. The slower rate of rotation of the can star 75 reduces the exit velocity of the filled cans as they are discharged from the machine to avoid ejection of fish from filled cans. In addition, the can star 75 rotates through its 120.degree. continuously in a one-step advance, rather than through a two-step advance with an intermediate stop as in prior machines.

  • Patent number: 4947617
    Abstract: The performance of packaging machines for the production of hinge-lid cigarette packs is limited by complex folding operations. In particular, these packs have hitherto been conveyed through the packaging machine by intermittently moved conveying members (folding turrets), the necessary folding steps thereby being carried out. In order to increase the performance of a packaging machine of this type, folding turrets (35, 36) are driven continuously. During the continuous movement of folding turrets 35, 36, the necessary folding of pack blanks (12) are made, especially by means of co-rotating folding members assigned respectively to a pocket (47, 74) of the folding turrets. During the continuous run, partially finished hinge-lid packs (10) are transferred from one folding turret (35) to the following folding turret (36) which is designed in a similar way to the first folding turret (35) and which completes the folding of the pack blanks (12).

    Abstract: An apparatus is disclosed for making bags or sacks from a continuous tubular film of thermoplastic material. The continuous tubular film is moved intermittently in a downward direction to a welding device, a cutter below the welding device, and a turret-like rotary conveyor below the cutter. A bag length is received by grippers on the rotary conveyor before it is welded and cut. When thus received the bag length is welded and cut, and the conveyor indexed by one step to present succeeding grippers to the tube. The tube is then advanced another bag length so that the succeeding bag is received in the succeeding pair of grippers. The process is repeated with succeeding bags. The bags on the conveyor are successively delivered to a transfer station where the grippers are opened to release the bags.
