Definitions

  • the invention relates to a device for winding and cross-cutting a running material web, which is wound on a drivable and brakable winding tube until a certain winding diameter is reached, wherein a contact roller presses the material web against the winding tube by means of a swivel arm, and before an unwound one , is transferred over part of its circumference wrapped by the material web subsequent winding tube in the winding position, a cutting member cuts the material web between the wound and the still unwound winding tube perpendicular to the direction of travel.
  • the material web can be, for example, a paper web, a film web or a plastic web provided with a magnetic coating.
  • the task is to separate the material web wound on a winding tube with a separating knife after reaching a certain winding diameter and to wind the new material web beginning that has arisen onto an empty winding tube while the full package is removed and replaced by an empty winding tube.
  • the almost completely wound winding tube leaves its winding position.
  • a new sleeve to be wound takes its place.
  • the running web is cut between the new and wound winding tube and lies against the new tube, whereupon the process just mentioned begins again.
  • the finished winding runs out in order to be removed. It has been shown that the outermost winding layer package in particular often shifts or is axially displaceable relative to the rest of the winding, particularly in the case of smooth material webs and at high machine speeds from the range of 300 m / min. This telescoping of the winding, that is to say deviations from the winding with the same edge, can damage parts of the winding through deformations.
  • a device of the generic type mentioned at the outset is known from GB-A 2 126 564.
  • a contact roller on the winding roll to be wound up, in order to squeeze air out between the layers and to prevent the web layers from being blown out to the side.
  • a winding device is known in which a driven pressure roller abuts the winding in order to overcome the inertia of the winding roller during the winding process. After the full winding diameter has been reached, this pressure roller is pivoted away from the winding and swiveled onto a winding core to be rewound in order to fix the new start of the web on the core there after the web has been separated.
  • the invention had for its object to achieve a stabilization of the winding pattern when braking the full winding reel to a standstill, the run-out time of the reel should also be reduced in order to achieve a quick reel change in a turret winder.
  • a material web (2) coming from a coating device (not shown) runs over deflection rollers (1, 3, 4) to the winding and cross-cutting device.
  • a contact roller (5) places the material web (2) on the winding (6).
  • a second contact roller (7) which is rotatably mounted on an arm (17), stabilizes the winding.
  • An identical one Device, namely contact roller (12) and arm (16) is provided in an analogous manner for the fully wound winding core (11).
  • the entire device (18) is turned so that the sketched state is reached. Then the material web between the empty winding tube (6) and the deflecting roller (8) is separated by a cross cutting device (15), and the newly created web start is simultaneously applied to the winding tube (6). Then the full roll wound on the winding tube (11) is braked on the outside diameter by the braked contact roller (12) to a standstill. The contact roller remains pressed against the reel for a selected period of time until it is pivoted against an empty winding tube in order to change the filled reel. The winder remains in this position until the winding core (6) is almost filled and the turning process described begins again.
  • each of the winding tubes is designed to be drivable and brakable and that the contact rollers (7, 12) which are present in addition to the usual contact roller, as in the already mentioned EP-A-0 503 363, can be braked.
  • the contact roller (12) acting on the full winding is braked with a braking torque which is suitable for preventing the winding from telescoping.
  • the size of the braking torque to be selected depends on the moment of inertia of the winding and the torque always acting on the winding tube, which results from the bearing friction of the tube bearing, the friction in the drive motor and the transmission gear.
  • an approximately 70 cm wide plastic web consisting of 15 ⁇ m thick polyethylene terephthalate, which was provided with a 3 ⁇ m thick magnetic coating, was used at a speed of 500 m / min. wound up.
  • the above-mentioned web which had a length of 10,000 m, could be brought to a standstill within 5 seconds without the outermost winding layers being blurred.
  • the winding behavior was excellent, the web also showed on the outer layers after the deduction. There are no scratches or damage to the glue point or the end and beginning of the web.
