Definitions

  • the invention relates to a wheel folder for a web-fed rotary printing press according to the preamble of patent claim 1.
  • Such wheel folder are known in various designs.
  • a 2/2-sized folding knife cylinder carries two rotating folding knives and also serves as a counter-cutting cylinder with two cutting bars and two sets of punctures for paper transport. It is cut with a 1/2 cutting cylinder, which carries a cutter bar and can also serve as a collecting cylinder using a puncture set.
  • the advantage of this widespread 2: 1 wheel folder is its robust, simple and economical construction. Disadvantages are the limitation to a maximum of 112 pages of collecting capacity and the performance limitation due to high centrifugal forces, which affect the collecting position when rotating on the double-speed, half-size cutting cylinder.
  • a 3 2-wheel fold is described, within which a 3/2 collecting cylinder designed as a hollow cylinder with three sets of punctures rotates an eccentrically offset folding knife carrier with two folding knives, the folding knife tips of which describe a three-pointed hypocycloid.
  • a 2/2 large cutting cylinder alternately cuts with two knives against three cutting bars which are supported by the hollow collecting cylinder.
  • 2-wheel rebate is the fact that the 2/2 cutting knife cylinder cuts against the hollow collecting cylinder, which for structural reasons is not very stable.
  • Another 3: 2-wheel rebate according to US-PS 31 44 249 works within the 3/2 hollow collecting cylinder with three rotating offset folding knives which are offset eccentrically. With this construction too, a 2/2 cutting cylinder cuts against a rotating, hollow 3/2 collecting cylinder, which also serves as a counter-cutting cylinder.
  • the cut is made independently of the hollow 5/2 collecting cylinder between two 4/2 solid cylinders.
  • One carries four knives, the other four counter-cutting bars and four puncture sets for further transport of the cut sheets onto the five puncture sets of the hollow collecting cylinder.
  • the invention has for its object to provide a gear folder for double and collective production of strong products at high running speeds, ie a cylinder ratio greater than 2: 1, in which the high cutting forces are absorbed by solid cylinders.
  • the advantages that can be achieved with the invention are, in particular, that the incoming strands in both double and collective production with the most uniform, i.e. not heavily pulsating paper feed can enter the folding cylinder group.
  • the geared folder can be designed with proven elements, if possible, in order to be used on high-speed standard newspaper presses with two plates (2/2).
  • the figure shows the folder according to the invention in a side view without a side frame.
  • the wheel folder according to the invention consists of a hollow 3/2 collecting cylinder 1 known per se with three controllable point sets, 2, 3, 4, which, however, lack the three paper cutting strips customary up to now.
  • an eccentrically offset folding knife carrier 6 rotates with two or three rotating folding knives 7, 8, 9, the tips of which describe three-pointed hypocycloids.
  • the hypocycloid tip emerging from the bottom of the 3/2 collecting cylinder sleeve 11 works with two folding rollers 12, 13 in such a way that a folding process takes place in the case of double production and with collecting pro Production only fold the folding knives 7, 8, 9 into the folding rollers every second copy that passes by.
  • the 3/2 collecting cylinder 1 is assigned a solid counter-cutting cylinder 14, preferably with two cutting bars 16, 17 and two controllable point sets 10, 15, and a massive cutting knife cylinder 18, preferably with two cutting blades 19, 20, is assigned to the far left is.
  • the 2/2 cutting cylinder is located on the right outside and turns counterclockwise. According to the invention, the 2/2 cutting knife cylinder 18 is on the left outside and rotates with the clock hand.
  • a further 2/2 solid cylinder which is not present in known 3: 2 wheel folding apparatuses, is arranged as a counter-cutting cylinder 14, so that the wheel folding apparatus according to the invention does not have two, but three, cylinders as previously.
  • the cut is made between two 2/2-sized solid cylinders 14, 18, ie no hollow cylinders, regardless of whether later double or collective production is used. However, this also means that the paper draw is even and not pulsating.
  • the 3: 2: 2 geared folder according to the invention thus also has similarly favorable properties as the 5: 4: 4 geared fold mentioned, but achieves this goal with significantly reduced costs and almost halved space requirements of the cylinder group.
  • the third production type "Double collected" is deliberately avoided, which is not used in standard newspaper presses with two plates.
  • Paper webs 5 are folded lengthwise via folding formers 21, 22 and the strands 23, 24 with drawing rollers 26, 27 and union rollers 28 are passed onto the counter-cutting cylinder 14 with two cutting strips 16, 17 and two sets of punctures 10, 15. To the left of this is the cutting knife cylinder 18 with two cutting knives 19, 20. About 180 ° after the cutting line, the counter-cutting cylinder 14 transfers the sheet to the punctures 2, 3, 4 of the 3/2-cylinder 1.
  • the eccentric knife carrier 6 runs eccentrically offset with two - or three - folding knives 7, 8, 9, the tips of which describe a three-pointed hypocycloid.
  • both upper tips of the hypocycloids remain within the 3/2 collecting cylinder 1, while the lower tip of the folding knife pushes the revolving sheets into the folding rollers 12, 13. If both folding knives work, each incoming pair of sheets is folded away (double production). Becomes a fold knife is shut down, only every second section is folded away, while the first section runs around the 3/2 collecting cylinder 1 a second time for the purpose of collecting. In contrast to other 3: 2 wheel folders, the collecting sheet does not run through the interface a second time. No shredding can occur because the collection process is not combined with the cutting process, but now takes place separately.
  • the cylinder ratio (number of fields) of cutting knife, counter-cutting cylinder with sheet guiding means (punctures) and collecting, folding knife cylinder can also be 2: 3: 3. The above written applies accordingly.
