Definitions

  • the present invention relates to a device for cutting a web according to the The preamble of claim 1 and a method for cutting a web according to the Preamble of claim 12.
  • Web-fed rotary printing machines print on a continuous material web, e.g. a Paper web.
  • the continuous web is printed in a cutter in Signatures cut, which are then folded in a folder or on different types are arranged or collected.
  • the Signatures e.g. branched into two streams and also braked.
  • To the To reduce signature length often has to be the ratio of angular velocity be enlarged between the folder and the printing units of the printing press. Therefore, the speed of the signature after being cut off the web was increased, which adversely affects downstream transport functions effect.
  • Signatures therefore often have to be braked in a braking device, which but often damage the signatures, e.g. by making donkey ears or that Clog the folder because it cannot be transported from or to the braking device works.
  • the U.S. 5,740,900 describes a device for dividing a product stream into a current A and a current B.
  • the signatures are captured by grippers, where alternate grippers rotate to divide the product flow. A cutter is not explained.
  • the present invention provides an apparatus for cutting a web of material is moved in a web direction at a web speed.
  • the device has a large number of cutting elements which can be moved in a straight line in the web direction Cutting the web into signatures and a variety of gripper elements that match the Interact cutting elements.
  • the distance can used between the elements to set the signature length.
  • the speed of the web in the folder advantageously does not have to be changed to set the signature length.
  • Each gripper element can comprise a gripper that grips the signature and on Wish slows down.
  • Each cutting element can comprise a knife and each The gripper element can comprise a groove against which the knife can cut the web.
  • Each gripper element can also have a retractable, laterally, i.e. across to Transport direction, include extending pin.
  • the device can also be a Include brake disc that cooperates with the pin so that the gripper elements are supported and braked by the brake disc.
  • the device may include a drive mechanism that drives the cutting elements in Path direction moved.

  • the cutting elements preferably comprise a laterally movable knife with two Blade that cuts a strip of material between the individual signatures or separates.
  • This type of knife has an advantageous effect on the production of Printed products, because a knife with only one blade possible defects in the cut or cannot remove when printing, which results in color from a signature in the Border area of the next signature can appear.
  • the strip of material used in the Using a knife with two blades arises, these shortcomings can be more beneficial Eliminate wise.
  • the device can also be an air nozzle and / or Include suction device with which the strip of material from the groove into which the Strips after cutting, can be removed.
  • a large number of cutting elements are moved in a straight line in the signature cutting area, wherein the cutting elements move in the web direction.
  • "Movable in a straight line” means here that the elements at least in sections on a substantially straight extending path are movable, in contrast to circularly movable elements, such as it is the case with conventional cutting cylinders.
  • the web comes with the multitude of Cutting elements cut into a stream of signatures, extending the signature length changed, depending on the controllable distance between the cutting elements in the Signature cutting area.
  • the signatures are made from a variety of gripper elements gripped, the gripper elements interacting with the cutting elements.
  • the method can also include alternately branching the signatures, to get a first and a second stream of signatures.
  • the cutting elements can be moved at web speed in the signature cutting area.
  • the method further sees a braking of the signatures after leaving the Signature cutting area and an acceleration of the cutting elements before they enter the Signature cutting area before, provided that this is advantageous for cross cutting the web contributes.
  • the method preferably sees the cutting of a strip of material between each individual signature.
  • This cutting step can e.g. from a laterally rotatable Knives are executed, which can have two blades.
  • the strip can then e.g. be removed by means of a blower or suction device. By a streak between the signatures, the quality in the marginal areas of the Signatures are improved.

  • the trailing edge 28 of the preceding signature is additionally removed from the gripper 21b Cut line pushed away. In contrast to most other folders without Needles, the cut signatures must be accelerated with this procedure to create a space between the trailing edge of the preceding and the To create the leading edge of the subsequent signature.
