Definitions

  • the film web 60 runs over a sensor roller 62, which is pivotably mounted in the device frame via link 64 and is biased into contact with the film web 60 by a spring (not shown).
  • the bearing pin of the link 64 located in FIG. 3 is connected in a rotationally locking manner to an angle transmitter 66, the output signal of which is thus proportional to the tensile stress in the film web 60.
  • the timing belts 108 and 110 run around rear and front deflection rollers 112, 114, which are supported by shafts 116, 118.
  • the shaft 116 runs freely, the shaft 118 is driven by a toothed belt 120, on which a central drive motor (not shown) of the machine works.
  • the gripping plates 216 are provided with a support 230 made of a material with a high coefficient of friction, e.g. made of sandpaper.
  • the hub 212 is connected to a shaft 232, which is also driven by the toothed belt 120. In this way, the grippers 208 are moved synchronously with the conveying speed of the bag web 10 and tear off bag web sections 28 (see FIG. 1), which comprise two bags, at regular intervals from the latter.
  • the position of the axis of the hub 212 is selected such that the upper sides of the gripping plates 214 lie essentially in the plane of the bag web 10 when torn off.
  • the grippers 208 transport the bag web sections 28 to a collecting drum 234, which carries pairs of mandrels 240 on flange-shaped end parts 236, 238 seen in axial top view.
  • Frame-fixed cam plates 242, 244 ensure that the grippers 208 are opened after the thickening of a bag web section 28.
  • the gripping plate 214 then runs past the stack which is in the process of being bent over, the side edge sections of the bag web sections 28 which have already opened.
  • a finished multiple bag block 32 also comes into a removal position, in which it is stripped from the mandrels 240 by a removal plate 262, which has a bent lower end, and tipped out of the machine.
  • the removal plate 262 is supported by levers 264 which are connected to a shaft 266.
  • a lever 268 is attached to the latter, the free end of which is articulated on the piston rod of a working cylinder 270.
  • the housing of the latter is hinged to the frame plate 42.
  • the pressure medium supply to the double-acting working cylinder 270 is controlled by the program control of the machine, adapted to the movement of the collecting drum 234.
