Definitions

  • the invention relates to a collecting cylinder for pin folder of rotary printing presses according to the preamble of claim 1.
  • Diameter-adjustable collecting cylinders are generally known in various designs. They are necessary for the paper tension control for collectors' products of different thicknesses.
  • Collection cylinders with circumferential elements extending from puncture carriers to puncture carriers are known both from DE-PS 16 11 330 and from CH-PS 417 646. However, the circumferential elements are not adjusted either with eccentric shafts in either one or the other.
  • peripheral elements are mounted in groups at their two ends on eccentric shafts, by means of which a radial adjustment of the peripheral elements is made possible. So that this adjustment is always carried out at the same time for each circumferential element group, each eccentric shaft has a pinion which is in engagement with a spur gear which is rotatably mounted centrally to the collecting cylinder (see also DE-PS 20 40 494). By changing the angular position of this spur gear relative to the collecting cylinder, the radial position of the peripheral segments and thus the active diameter of the collecting cylinder are inevitably changed.
  • Another disadvantage has the gear connection mentioned, which can be soiled by paper dust etc. if the same setting of the collecting cylinder diameter is maintained over a long period of time, so that it comes to a jam during a subsequent adjustment.
  • the invention has for its object to provide a collection cylinder avoiding the disadvantages listed.
  • the object is achieved according to the invention in that at least one eccentric shaft of each circumferential segment group is mounted in the collecting cylinder body so that it can be swung out radially.
  • the measures according to the invention make the inner parts of the collecting cylinder practically freely accessible. Another measure allows any circumferential element group to be swung out without having to release the actuator of their eccentric shafts.
  • each eccentric shaft 6 On one end of each eccentric shaft 6, an adjusting lever 10 is fixedly mounted, which is connected in an articulated manner to an adjusting disk 12 by means of a push rod 11.
  • the adjusting disc 12 is in turn centered on the collecting cylinder 1, e.g. mounted rotatably on the collecting cylinder axis 13 and either connected to a known mechanical remote adjustment (not shown) or, in the case of a simple version for manual adjustment, provided with a suitable fixing device.
  • each eccentric shaft 6 is provided, for example, with a hexagon 14 or the like, onto which a conventional turning tool can be attached.
