Definitions

  • the invention relates to a device for longitudinal creasing of paper webs which can be transported by means of a traction device containing two pulling rollers, of which at least one is driven, in particular in a folder provided with a folding blade, to at least one driven, disc-shaped creasing knife and to be provided with folding products provided with at least one longitudinal fold a counter-holder cooperating with this.
  • a compensating coupling can be provided for coupling the bushing which receives the creasing knife to the associated shaft.
  • a coupling advantageously enables the shaft and shaft to be axially offset, so that the creasing knife for activating or passivating the creasing device can be subjected to a slight radial movement with respect to the associated shaft.
  • the holder assigned to the creasing knife can have a bearing housing which accommodates the bush, which is pivotably mounted on a slide which is preferably displaceably arranged on a support rod fixed to the frame and is adjustable by means of an adjusting device supported on the slide.
  • a bearing housing which accommodates the bush, which is pivotably mounted on a slide which is preferably displaceably arranged on a support rod fixed to the frame and is adjustable by means of an adjusting device supported on the slide.
  • the counter-holder assigned to the creasing knife can advantageously be designed as a split ring which is inserted into a circumferential groove of a pulling roller lying opposite the traction rollers of the shaft driving the creasing knife.
  • a split ring can be easily assembled and enables a claim independent of the associated pull roller right material selection.
  • a folding former is indicated at 1, over which the paper web 2 is guided.
  • the paper web leaving the former is provided with a first longitudinal fold and, in a manner known per se, is to be subdivided into sheet-shaped products in a folder downstream of the former 1, which is no longer shown here, which are first folded laterally and then again longitudinally folded.
  • a combined pulling and creasing device 3 is arranged downstream of the former 1, which ensures the web feed and with which the web is creased to mark the second longitudinal fold.
  • Two pull rollers are provided to accomplish the web feed, as can best be seen from FIG.
  • One of these traction rollers consists of a continuous shaft 4, which ver over its length with several traction rollers of the type indicated at 5 see is.
  • the shaft 4 is provided in the area of the machine side wall with a drive element, not shown here.
  • the other, with its circumference 7 against the traction rollers 5, is to be formed in the illustrated embodiment simply by a tube 6 which is freely rotatable in the machine side wall.
  • a disc-shaped creasing knife 8 is provided for creasing the paper web passed between the tension rollers 5 and the tube 6, which here cooperates with its associated peripheral edge with an associated, annular counter-holder 9.
  • the counterholder 9 expediently consists of a divided ring made of hardened steel, which is inserted into an associated circumferential groove of the tube 6.
  • the two ring halves are simply held together by countersunk screws 10.
  • the creasing knife 8 is fastened on a bushing 11 which is penetrated by the shaft 4.
  • the diameter of the sleeve bore is larger than the shaft diameter, so that there is sufficient radial play.
  • the drive of the bush 11 and thus of the creasing knife 8 is removed from the driven shaft 4 ' via a compensating coupling.
  • the bushing 11 is provided in the region of its flank-widened end face opposite the creasing knife 8 with a radial groove 12 into which an axially parallel pin 13 engages, which is received on a drive ring 14 which can be fixed on the shaft 4.
  • the drive ring 14 is fixed on the shaft 4 by a radial screw 15 which engages with a driving lug 16 in a recess 17 of the shaft 4.
  • the bushing 11 carrying the creasing knife 8 and penetrated by the shaft 4 is freely rotatable with its outer circumference stored on a holder supported on the machine frame.
  • this holder consists of a bearing housing 18 comprising the bush 11, which in turn is pivotally mounted on a slide 20 by means of a sleeve 19, which is received on an axially parallel ' supporting rod 21 fastened to the machine side frame.
  • the carriage 20 is formed in the embodiment shown simply as a sliding sleeve by means of which he s in the area between two adjacent draw rolls 5 is displaced, the entire holder and the associated-Rillmes- 8 back and forth.
  • a clamping ring 22 is provided to fix the slide 20 on the support rod 21 designed as a sliding guide, which can be tightened by means of a screw 23. To move the holder, therefore, only the screw 23 has to be loosened.
  • the counter holder 9 is located where the grooving should normally take place. However, it would also be conceivable to provide several counterholders distributed over the axial adjustment range of the creasing knife 8. In the exemplary embodiment shown, the creasing knife 8 should simply cooperate outside the counter-holder 9 with the circumference 7 of the pulling roller 5 opposite the pulling rollers 5 of the shaft 4, as indicated at 8a. The lateral displaceability of the creasing knife 8 ensures an exact axial adjustment in any case. To ensure easy tracking of the drive ring 14, the recess 17 of the shaft 4 assigned to the driving lug 16 is designed as a longitudinal groove. The drive ring 14 can therefore by tightening the Screw 15 can be set practically at any point on the shaft 4.
  • the creasing knife 8 can be turned on or off the circumference 7 of the opposite drawing roller or the associated counter-holder 9.
  • the bearing housing 18, which is pivotably mounted on the slide 20 by means of the sleeve 19, can be pivoted by means of an adjusting device with respect to the shaft 4 passing through the bushing 11.
  • the compensating clutch formed by the axial pin 13 engaging in the radial groove 12 allows the resulting axial displacement.
  • the adjusting device consists, as can best be seen from FIG.
  • a plunger 24 which is articulated on the bearing housing 18 and which passes through a sleeve 26 which is opposite the articulation and is supported on an arm 25 of the carriage 20 and is then attached by adjusting nuts 27 against the force of a between the Sleeve 26 and the bearing housing 18 arranged, here the plunger 24 surrounding spring 28 is supported.
  • the sleeve 26 engages. an external thread into a threaded bore of the arm 15 and can thus be adjusted to adjust the spring tension of the spring 28, which ensures the desired contact pressure between the creasing knife 8 and the associated counter-holder 9.
  • a clamping screw 29 is provided to block the sleeve 26.
  • creasing knife 8 Only one creasing knife 8 is shown in the figures. However, a plurality of creasing knives with an associated counter-holder can be provided between the two pulling rollers over the length of the shaft 4.
