  • the device enables Removal of printed products in rows from the original Scale stream also pull apart and separate Forward side-to-side interlocking folded Printed products.
  • Such or similar devices are used at the exit of rotary printing presses, the printed products at a high speed of 40,000, for example Deliver pieces per hour.
  • the level at which the print products running over them are currently practically without a guide are to an uncontrollable relocation of the Print products, especially when the conveying speed, following the technical development, for example to 100,000 pieces per hour, or if the conveyor speed without corresponding readjustments is changed on the device in question.
  • the present invention is therefore based on the object to train a device according to the generic term so that an uncontrollable relocation of the fabrics in question, such as. Print products, even at high conveying speeds or changes in conveyor speed omitted.
  • a printed product from an incoming stream of flakes side pulling clamping band unit without piercing fork and Level is known from DE 32 12 350 A1, as well as two essentially Y symmetrical to a feeding one Conveyor device connecting such clamping belt units are known under the term "spreading band".
  • the device in question is only used for pulling apart staggered folded printed products, a controlled use of the respective clamping band unit unnecessary.
  • a fabric 4 such as e.g. Printed products
  • two to the central axis 10 of the conveyor 8 essentially symmetrically arranged clamping band units 12 and 14, which are essentially opposite the central axis 10 Take the same acute angle ⁇ or ⁇ .
  • the conveyors 8, 16, and 18 can essentially consist of endless conveyor belts, on which the fabrics 4 rest loosely.
  • FIG. 2 are details of each of the two clamping band units 12 and 14 can be seen together with the adjacent ends of conveyors 8 and 16 and 18 respectively
  • Clamping band unit 12 and 14 each contain an endless Upper clamping band 20 and an endless clamping lower band 22 with one Run 24 or 26, where between that of the relevant clamping band unit recorded fabric 4 in the shingled stream run through clamped.
  • the strand 26 of the lower clamping band 22 extends between a deflection roller 28 on the input side and an output-side deflection roller 30, the first of which fixed and the second for a purpose that will be seen later is longitudinally adjustable.
  • the deflection roller 30 After leaving the deflection roller 30 runs the clamping lower band 22 in succession by one compliant mounted tension roller 32, a drive roller 34 and a guide roller 36 before it reaches the deflection roller 28 on the input side.
  • the highest one is located Surface line of the deflection roller 28 essentially on the same Level as that of an end deflection roller 38 of the conveyor 8, whereby a step formation is avoided.
  • the upper clamping band 20 runs in succession over an input side Deflection roller 40, an exit-side deflection roller 42 - which, like the deflection roller 30, is longitudinally adjustable -, then a deflection roller 44, a drive roller 46, a deflection roller 48 and a tension pulley 50 before it is the input side Deflection roller 40 reached.
  • a deflection roller 44 is additional to the output-side deflection roller 42 also the input-side Deflection roller 40 in the running direction of the clamping band strands 24 and 26 relocatable, and the storage is accordingly the tension pulley 50 designed to be a relative to allow large stroke.
  • additional the deflection roller 44 are designed as a tension roller.
  • the input-side deflection roller is 40 of the upper clamping belt 20 with the conveying speed of the relevant clamping band unit 12 or 14, as by the Band dreams 24 and 26 is determined from their extended in Fig. 2 drawn position, in which it is the input side Deflection roller 28 of the lower clamping band 22 lies in the Position shown in dashed lines retractable, so one Takeover of surface images 4 from the conveyor device 8 prevention.
  • FIG. 1 The figure also shows in FIG. 1 in Appearance pinch rollers 56 over the end of the conveyor 8, which have the task of delivering the Hold down fabric 4 in the transfer area.
  • FIG. 3 12 and 14 The engagement of the two clamping band units is now based on FIG. 3 12 and 14 explained.
  • the scale stream 6 delivered by the conveyor device 8 recognize and on both sides the incoming ends of the clamping band units 12 and 14. More specifically, of these, those are about input-side deflection rollers 28 and 40 running sections the upper clamping band 20 and lower clamping band 22 shown. While the clamping band unit 12 is in the active state with advanced Deflection roller 40 is shown, the clamping band unit 14 with retracted deflection roller 40 in inactive State, being out of engagement with the sheets 4 remains. Accordingly, the foremost sheet 4 of the clamping band unit 12, captured at the left front corner, and deducted in the conveying direction of the clamping band unit 12.
  • the device 2 can be activated at the same time both clamping band units, 12 and 14, again serve, staggered folded printed products to separate from each other, with the one that emerges on the left Printed product from the clamping band unit 12, the right side protruding from the clamping band unit 14 detected and discharged becomes.
  • both clamping band units, 12 and 14 again serve, staggered folded printed products to separate from each other, with the one that emerges on the left Printed product from the clamping band unit 12, the right side protruding from the clamping band unit 14 detected and discharged becomes.
  • the device according to the invention 2 are just as versatile as the one at the beginning mentioned literature reference EP 0 578 614 A1.
  • angles ⁇ and ⁇ of the two are expediently Clamping band units 12 and 14 with respect to the central axis 10, and separately, adjustable, as well as the position the clamping band units 12 and 14 along the central axis 10 and above all, it should be adjustable across the board, optimal takeover of fabrics 4 depending on their format, their weight, their surface quality and the like.
