Definitions

  • the present invention relates to a cutting device with variable section length for cutting a web strand in signatures of the desired length, especially in a folder of a web-fed rotary printing press, according to the preamble of Claim 1.
  • Web-fed rotary printing presses usually have a subordinate to the printing unit Folder.
  • the folder cuts and folds a paper web or web strand, to create a signature or sheet of a certain length.
  • Known folders with variable section lengths are usually in two categories assigned.
  • the first category changes the size or length of the signatures, by parts of the folder, e.g. the collecting cylinder, the knife cylinder or the The jaw cylinder can be replaced.
  • the disadvantage of this solution is that it is costly and time consuming as it takes considerable time to separate parts of the To replace the folder.
  • the Angular speed of the knife cylinder relative to the speed of the web strand increased and thereby accelerated the signature to the front edge of the signature in the to bring the desired position on a transfer cylinder.
  • the disadvantage of this technique lies in the difference between the speed of the knife cylinder and that of the web strand.
  • the peripheral speed of the knife cylinder must be the same or be higher than the speed of the web strand.
  • the Circumferential speed of the knife cylinder considerably higher than the speed of the web strand in order to achieve the shortest possible signature length Quality of the cut.
  • the speed of transport of the signatures after the cut corresponds to that of Circumferential speed of the knife cylinder. If the peripheral speed of the Knife cylinder is increased relative to the speed of the web strand, the Speed of the signatures also in relation to the speed of the Web strand to be increased. This requires the signatures to be new, higher Speed can be accelerated. This can be accelerated by the signatures cause the position of the signatures to change. This change in the position of the Signatures can affect the quality of the signatures as well as the performance of the cutting system and thus reduce the performance of the entire folder.
  • An adjustable folder for web-fed rotary printing presses is in GB 1,214,339 described.
  • the variable folder is equipped with a knife cylinder, which with cooperates with a transfer cylinder. Between the knife cylinder and the Transfer cylinder is formed a gap through which the web is passed.
  • the Transfer cylinder carries web sensing elements around its circumference, each a gripper for grasping the leading edge of a web emerging from the gap Folding knife that interacts with a folding flap in a third cylinder and one Include support surface with the associated knife of the knife cylinder cooperates.
  • the angular position of the gripper and the folding knife are at the Axis of rotation of the transfer cylinder in relation to the angular position of the support surface adjustable to change the sheet size.
  • DE 39 34 673 C2 describes an adjustable in the format length Cross cutting device for running webs.
  • a path runs between one Knife cylinder and an associated cylinder of the same diameter.
  • the Knife cylinder is equipped with cutting knives on its periphery.
  • the him assigned cylinder carries elastic cutting strips, which with the cutting knives Knife cylinders work together to cut the web.
  • the cutting knives and the Cutting bars are pivoted around swivel axes.
  • the swivel axes lie in the cylinders and are arranged parallel to the cylinder axes.
  • the cutting knives and the cutting bars are in the way pivots that they move against the direction of web travel.
  • a disadvantage of that in the DE 39 34 673 C2 described cross-cutting device adjustable in format length is that a more complicated swivel mechanism is needed because the Movement of the cutting knives and the cutting bars synchronously with each cutting process must run.
  • the transfer cylinder has a section that can be changed on its periphery Diameter, subsequently also adjustable or changeable diameter section called, on, wherein the adjustable diameter section with the transfer cylinder connected, or is arranged on this and in the direction of the cylinder central axis and is movable away from the cylinder center axis by the desired length of the Set signatures.
  • the cutting device according to the invention has the advantage that it is easy to open Different signature lengths can be set without parts of the cutting device need to be replaced.
  • the adjustable diameter section an adjustable roller, e.g. with a diameter in the range between 5 and 20 cm, that towards and away from the cylinder center axis is movable.
  • a lifting and lowering device e.g. one pneumatic cylinder, one Winch e.g. a linear winch and / or an eccentric winch, or a rack based lifting and lowering mechanism attached, by means of which the adjustable Diameter section towards the cylinder center axis to and from the cylinder center axis can be moved.
  • a lifting and lowering device e.g. one pneumatic cylinder, one Winch e.g. a linear winch and / or an eccentric winch, or a rack based lifting and lowering mechanism attached, by means of which the adjustable Diameter section towards the cylinder center axis to and from the cylinder center axis can be moved.
  • a gripper and a Folding knife on the periphery of the transfer cylinder at a predetermined distance of the cylinder center axis connected to the transfer cylinder, the adjustable Diameter section between the gripper and the folding knife is arranged. That has the advantage that the knife cylinder with respect to the transfer cylinder in one predetermined position can remain, even if the adjustable diameter section on the center of the transfer cylinder is moved to or away from it.
  • a is on the knife cylinder Cutting knife arranged, which with a on the periphery of the transfer cylinder arranged cutting bar interacts and the material web in signatures cuts when the knife cylinder and the transfer cylinder synchronously with each other rotate.
  • the Transfer cylinder a constant angular velocity, which gives the advantage that complicated control of the speed of rotation of the transfer cylinder is not necessary is.
  • the adjustable Diameter section each connected to a gripper and a cutting bar.
  • the gripper and the cutting bar are preferably together with the adjustable Diameter section movable towards and away from the cylinder central axis.
  • a folder of the invention with a variable section length comprises one Knife cylinder and a transfer cylinder, which is designed in such a way and with the knife cylinder cooperates that a web strand guided on it in signatures is cut to the desired length.
  • the transfer cylinder has one Cylinder center axis and a periphery and has an adjustable Diameter section on which is preferably on the periphery of the transfer cylinder is arranged.
  • the adjustable diameter section is preferably with the Transfer cylinder connected and is in the direction of the cylinder center axis to, or from this can be moved away in order to set a desired section length of the signatures.
