Definitions

  • the invention relates to a device for transfer a threading strip of a material web, in particular paper or cardboard web, according to Claim 1, a device for transfer a threading strip of a material web, in particular paper or cardboard web, according to claim 14 and a method for transferring a Threading strip of a material web according to claim 16th
  • Devices of the type mentioned here are in Machines for the production and / or processing of a Material web used and are used for transfer a threading strip separated from the material web from a takeover area along a free train to a transfer area. This The process is also called threading the threading strip referred to in the web path. This happens often at full machine speed, which can be up to 2000 m / min and above. In a web production and / or processing machine free trains cannot always be found avoid, for example after a duo centri press or after the dryer section.
  • a transfer device is known from DE 23 65 438 B2 for a dryer section of a paper machine emerged, the dryer section several drying cylinders and guide rolls over which the material web together with you the material web supporting dry felt is meandering.
  • a threading strip of the material web in the dryer section is a transfer belt provided that from a rest position outside of the web travel path transverse to the machine direction in the web path is moved in, the threading strip between the dry felt and the transfer belt is held clamped. Because the transfer belt only in cooperation with the dry felt can be used are the possible uses the transfer device to the areas of Machine limited in which the web of material during normal operation of dry felt or the like is supported. In the areas of the machine, in which the web of material in a free Train is guided, so without the support of a belt for example from one cylinder to the next runs, the known transfer device not be used.
  • a transfer device is known from WO 99/41451 A1 with two transfer belts, between which the threading strip is arranged. So that between the transfer belts and the threading strip no slip occurs, one has the conveyor belts have tooth-shaped elevations, into corresponding openings in the other transfer belt intervention. This will make the one in between arranged threading strips quasi perforated.
  • the disadvantage here is that the strength properties the threading strip is reduced so that the threading strip can tear off and a transfer process is started repeatedly must become.
  • the transfer belts are outside the path of the web via specially designed guide rollers led, that means the threading strip led out of the side of the web path must be what the risk of demolition further increased.
  • the transfer device a complex structure.
  • Another goal is a method for transferring the threading strip specify that has a high level of functional reliability.
  • a transfer device proposed with the features of claim 1. It is used to transfer a threading strip a material web, for example one Paper, cardboard or textile web in the area of a free web train from a takeover area to one Transfer area.
  • free train understood a section of the track, in which the web of material during normal operation the web manufacturing and / or processing machine not from tape, felt, or the like is led, but runs without support.
  • the transfer device has first and second Conveyor belts run along the free Rail train relocatable and guided against each other are, the threading strip between the Conveyor belts are held clamped.
  • the transfer belts are using a tape transfer device Can be moved across the web direction such that they come from an outside that means rest position offset to the side of the path into and out of the web path are. Because of this configuration the transfer device can be used universally, both in the area of a free train as well as in the areas of the machine in which too one or more tapes, felts or the like for Support of the material web are provided. Advantageous is also that in normal machine operation, if the transfer device is not is needed, the transfer belts outside the Web runway can be arranged so that they run the material web or web processing / production do not bother.
  • the transfer belts are passed over at least one disc, that on an end face of a roller, over which preferably the material web in normal operation of the Machine is guided, is freely rotatable. This can reduce the speed of the transfer belts regardless of the running speed of the Material web can be adjusted as to what maintenance of the transfer device advantageous is because the transfer belts are in progress Operation of the machine can be stopped.
  • the transfer belts are preferably during the production or processing of the material web, so if no threading strip is transferred must become silent.
  • the displacement path the transfer belts transversely to the web running direction essentially the same size as that Conveyor belt width.
  • Their width is preferably in a range from 20 mm to 600 mm.
  • the displacement path is therefore relatively small, so that the transfer belts very quickly from their parking position out into their transfer position within the web path are relocatable.
  • the flyover of the threading strip takes place here on Edge of the railway track.
  • Another one Embodiment is provided that the transfer belts to the middle of the path are relocatable.
  • the threading strip is at this embodiment from the middle of the material web cut out and roughly in the middle of the machine transferred. The advantage here that side air currents or pollution practically no influence on the threading strip transfer to have.
  • the transfer device are the transfer belts trained such that at least the Sides of the conveyor belts that are used during a Threading process lie against each other and between to whom the threading strip is held flat or at least essentially flat are. Because of this configuration, the Threading strips practically not deformed or damaged, but rather kept carefully, so that tearing off the strip is practically impossible can be.
  • the transfer belts can be made from virtually any any material can be made, the flexible Has properties. Preferably exist the transfer belts made of plastic, metal or Leather.
  • the choice of the material of the transfer belts can be done according to different criteria for example, according to the location of the transfer route. For example, a metal one Transfer belt more temperature resistant, however heavier than a plastic transfer belt, being wear of the rollers, about which the transfer belt is guided at plastic conveyor belt less is.
  • the transfer belts are preferably very thin executed and have a thickness that in a Range is from 0.2 mm to 4 mm.
  • Made of metal Conveyor belts preferably only have a thickness of about 0.2 mm around the Thermal resistance and the speed difference between the transfer belts in the Area in which this is, for example, via a roller or the like are kept small.
  • a low-thickness transfer belt also has the advantage of being practical when driving out no shear forces occur at the edge of the web.
  • the sides of the transfer belts, with the threading strip coming into contact can be smooth or have a certain roughness.
  • the frictional forces between the threading strips and the respective transfer belt be that when a critical Longitudinal tension of the threading strip, for example due to a speed difference between the threading strip and at least one the transfer belts can occur, some Slip is allowed.
  • the threading strip can so relative to the transfer belts move so that a strip tear due to high Shear forces can be safely avoided.
  • the transfer belts are preferably gas-permeable, for example, designed like a sieve, which has the advantage that a floating of the Threading strip when it is picked up or Introduction between the transfer belts on The beginning of the transfer line is prevented. Moreover the formation of air boundary layers is avoided. Hence the delivery or transfer this threading strip at the end of the transfer line to the subsequent part of the Machine by the possibility of rear ventilation, for example blowing through the transfer belts facilitated.
  • the transfer device is, for example, inside a coating device, a smoothing unit, a roller or for transferring a threading strip from a dryer section to one subsequent part of the machine is functionally reliable used.
  • a transfer device is also used to achieve the object with the features of claim 14 proposed. This is used to transfer a Threading a material web in the area of a free web train from a takeover area a transfer line to a transfer area and has to do this along the free web train relocatable transfer belt on which the Threading strips during the transfer process is applied. During the transfer, the threading strip in the area of the free web train so one-sided supported. With the help of a belt transfer device is the transfer belt across or in essentially back and forth across the web movable so that it is out of a rest position is movable into the web path. by virtue of guiding the threading strip through the transfer belt can be used on complex strip guiding systems, such as blowing air devices, to be dispensed with.
  • the transfer device is characterized by a high level of functional reliability out.
  • a method is also used to solve the problem Transfer of a threading strip with the characteristics of claim 16 proposed.
  • the one Material web separated threading strips is inside a machine for manufacturing and / or processing the material web in the area of a free Train from a takeover area to a transfer area transferred. For this, at least one along the free web train and transverse to the web running direction relocable transfer belt used, where the threading strip at least in the area the overpass stretch and supported becomes. It is envisaged that after a demolition of the Material web or when starting up the machine the transfer belt from a parking position moved into the web path and after the overpass is shifted back into the parking position. The process is characterized by a high level of functional reliability out. It is also advantageous that the Transfer of the threading strip at machine speed can be done what the machine efficiency improved.
  • a preferred embodiment are used for transfer of the threading strip at least two transfer belts inserted between which the threading strip be held non-positively.
