Definitions

  • the above invention relates to a role for a Drying device of a rotary printing machine.
  • drying facilities between the printing units provided from a number of parallel to each other arranged roles exist, which follow extend the printing cylinder of the printing unit upwards and run down at a turning point to the paper web to promote another printing unit.
  • Drying devices of the type described have the Task, from the paper web to the printing ink contained solvents immediately after the paint application remove and at the same time drying the applied Initiate printing ink.
  • the webs to be printed usually consist of a paper material that is strong is hygroscopic, it can be stated that the Sheets after being connected to the impression cylinder a significant amount of paint particles and
  • the object of the above invention is to address the disadvantages to avoid the state of the art and a novel Roll for the drying device in one Propose rotary press, with this new role the possibility is opened with certainty wrinkling in the longitudinal direction of the printed To face paper web.
  • this object is achieved by using a Roll resolved in the drying facility one Rotary printing press near a printing unit in Form of rollers arranged parallel to each other is provided is, with each roll a plurality of circumferentially has grooves provided at the same distance and these Grooves are arranged parallel to the longitudinal axis of the roller and be limited by protruding ribs.
  • each roll In the circumferential direction of each roll, a number of Grooves are formed which allow the running tape only partially lying on the protruding ribs. Since the ribs can limit free spaces in the form of grooves the paper web in when the roll overflows Extend the cross direction and any wrinkles eliminate the web and allow the paper web to settle in Smooth out cross direction.
  • drying facilities used in Agreement with the printing units e.g. one Rotary printing press are provided from a variety of parallel, rotating rollers 1 consist.
  • Drying devices are usually the ones described Kind equipped with rollers that have a smooth peripheral surface exhibit. While the web 2 is running along the Drying devices are formed in the known Establish unwanted wrinkles and wrinkles that result in Extend the longitudinal direction of the paper web.
  • the invention now proposes the peripheral surface (C) of the interrupt known role and at an equal distance to provide intended grooves, these grooves extend parallel to the longitudinal axis of the roll.
  • the grooves which consist of a recess, alternate from with elevations that form ribs 5.
  • the grooves 4 and the ribs 5 extend parallel to Axis X of roller 1 and are in the circumferential direction of roller 1 arranged.
  • the figure 2, the cylinder 1 in front view shows that the paper web 2 during the sequence in the direction of arrow (f) only rest on the ribs 5 of the roll.
  • the paper web 2 alternately overhangs Ribs 5 and free spaces 4 and can thus be in Move transverse direction as soon as one designated as groove 4 Free path of role 1 is overrun.
  • Imaginary extend from the axis X of the roll 1 Sector sectors that are schematically labeled S.
  • the angle ⁇ becomes dependent on the diameter of the roll 1 selected, the depth of the grooves 4 is dependent on Diameter of the roll.
