  • the Drive pulley 27 runs parallel to side pane 4 of the first support body 3 and lies against this (Fig. 1).
  • the folding jaw cylinder 1 has the side windows 4, 11 and the drive pulley 27 each have a cutout 28, 29, 31 on.
  • a Working cylinder 32 e.g. B. a double acting Cylinder-piston unit 32, 33 arranged.
  • the Working cylinder 32 is by means of one on its housing 35 attached bracket 40 and a screw 72 with the side window 11 connected.
  • the free end of the Piston rod 34 is via a screw 73 with the Side window 4 connected.
  • the cylinder-piston unit 32, 33 is expedient designed as a membrane cylinder. That is, the piston is 33 e.g. B. disc-shaped and has on it Periphery an annular membrane 36.
  • the Diaphragm 36 is with its outer circumference on the housing 35 of the Cylinder 32 set. This can e.g. B. by Clamp between two housing parts. Consequently is between a first chamber 37 of the cylinder 32nd and a second chamber 38 of the cylinder 32 a gas and liquid-tight separation achieved.
  • a piston stroke this cylinder 32 is only a few millimeters (Fig. 2).
  • the first chamber 37 is with a pressure medium, for. B. a liquid 43, e.g. B. hydraulic oil filled.
  • the Chamber 37 is an outlet 39 and a Line 41 with a known, for. B. on a support 9th of the second
  • Support body 8 attached energy storage, z. B. Hydraulic accumulator 42 connected.
  • the hydraulic accumulator 42 has liquid 43 on the line-near side and in one stretchable or compressible gas sack 44 on. This gas can consist of air or nitrogen.
  • the second chamber 38 of the cylinder 32 filled with gas 44 is connected to a compressed air source (not shown) via an outlet connection 47 and a line 48.
  • the line 48 initially runs inside the shaft 2.
  • a known rotary inlet 49 located at the shaft end connects to a line 51 which leads to the compressed air source (FIG. 1).
  • a synchronizing device 52 is located in a recess 53, 54, 56 of the disks 4, 11, 27. The synchronizing device 52 is located approximately diametrically opposite the cylinder-piston unit 32, 33 and can be arranged on the drive disk.
  • the synchronization device 52 consists of a synchronizing coupling gear.
  • the drive pulley 27 is fixed to one end of its recess 56 L-shaped bearing block 57 connected.
  • the bearing block 57 is fork-shaped on its shorter leg.
  • In the fork 58 is guided by a two-armed lever 59, which is mounted centrally on a bearing pin 61.
  • the bearing pin 61 passes through the fork 58 in a radial direction Direction to side window 4; 11.

  • the operation of the jaw cylinder is like described below. While feeding one Paper web in a rotary printing press or in one associated folder turns Jaw cylinder 1 with a low speed, d. H. in slow speed. Since no products yet Inclusion in the jaws 7; 13 are present causes the in the second chamber 38 of the Cylinder-piston unit 32, 33 supplied compressed air that the liquid in the first chamber 37 the line 41 and the throttling direction acting throttle check valve 46 slowly into the Hydraulic accumulator 42 flows. The air pressure is approx. 3 to 6 bar and is higher than that in the first chamber 37 acting pressure. Also, instead of using compressed air acted chamber 38, the counterforce by means of a Spring are generated. As a result, the two move Support body 3, 8 and thus the jaw parts 7, 13 opposed to each other until a preset Gap with a minimal width, e.g. B. of 0.1 mm as Basic setting is reached.
  • a preset Gap with a minimal width, e.g. B. of 0.1 mm as Basic setting is
  • This gap can be made by means of a stop can be preset.
  • the stop is z. B. from a bearing block 74 fastened to the side window 4, which receives a lockable screw 76. On The end of the screw 76 interacts with the side window 11 together (Fig. 4).
  • the liquid is without the throttling effect of the throttle check valve 46 quickly from the Hydraulic accumulator 42 to the first chamber 37 of the Cylinder-piston unit 32, 33 deducted.
  • the piston 33 moves in the direction the second chamber 38 filled with compressed air as long as until the cam roller 17 the highest point of the Control curve has reached 18 and the Close the jaw parts 7, 13 again.
  • the liquid in the first chamber 37 strives, again, about the throttling direction of action of the Throttle check valve 46 in the hydraulic accumulator 42 to expire.
  • the first chamber 37 of the working cylinder 32, 33 is So acted on with a pressure medium, the Supply and discharge of the pressure medium with different Quantities per unit of time take place (the supply takes place with greater speed than the removal).
  • the speed of delivery is a multiple, d. H. at least twice the speed of discharge.
  • the folding flaps 7, 13 set to this thickness.
  • the synchronizing device 52 ensures even setting of the jaw gap in both directions.
  • the working cylinder 32 can also between one Support body and a movable relative to this Jaw part or between an actuator, e.g. B. the cam roller 17, and the associated jaw part be arranged.
