Definitions

  • the invention relates to a device for the treatment of a web with a transport device having two transport strands which fix the edges of the web and transport the web, each transport strand is guided circumferentially on each inlet side and an outlet-side deflection, a winding device to the treated Web to wind up a winding and means for traversing the web.
  • Means for traversing the web are required in order to produce a uniform goods roll without a so-called "bowl". Burrs are caused by the fact that the edges of the web were formed by more stable selvedges or stabilized by glue application in knitwear. The winding then typically has a concave shape because the winding diameter is smaller in the middle of the web than at the edges.
  • a device for the transverse displacement of textile belts when winding on textile machines which has a transport device with two spreader chains, which fix the edges of the textile bands and transport the textile tape.
  • the textile belt In front of the deflection point of the spreader chains, the textile belt alternately comes into contact with one of two rotating disks whose eccentric part protrudes just above the level of the textile belt.
  • the one side edge of the textile tape is lifted from the spreader chain, causing a shift of the textile tape in one transverse direction.
  • the disc sinks below the level of the textile belt again and the disc under the other side edge is used, whereby a shift of the textile tape in the other transverse direction is effected.
  • the invention is therefore based on the object to improve the means for traversing the web and to allow a short path to the winding device.
  • the device according to the invention for the treatment of a material web consists essentially of a transport device which has two transport strands which fix the edges of the web and transport the web, wherein each transport strand is circumferentially guided over one inlet side and one outlet side deflection and a winding device to the to treat treated web to a winding. Furthermore, means for traversing the web are provided, which cause a reciprocating displacement of the two outlet-side deflection transversely to the transport direction of the web, wherein the reciprocating displacement of the two outlet-side deflection causes a corresponding reciprocal displacement of the edges of the web , so that the edges of the web on the winding come laterally offset from each other.
  • the traversing of the web takes place according to the invention thus already at a time at which the web edges are still fixed by the two transport strands. It can therefore be dispensed with between the take-off roller and the winding device previously provided traversing roller, so that the web reaches the shortest path for winding.
  • the means for oscillating the material web are preferably designed such that the distance between the two outlet-side deflection devices remains the same during the traversing.
  • the means for traversing the material web comprise at least one lifting device for displacing the two outlet-side deflection devices.
  • the lifting device or lifting devices can be formed for example by an eccentric and selectively driven electrically, pneumatically or hydraulically.
  • a control device is provided which is in communication with the transport device and / or the winding device in order to control the means for traversing the material web in dependence on the transport speed and / or the diameter of the winding.
  • each transport strand can be assigned its own drive or the two transport lines are driven by a common drive.
  • the two outlet-side deflection devices are housed in side posts and the means for traversing the web cause a reciprocating displacement of the side stand.
  • the in the Fig. 1 and Fig. 2 Device for the treatment of a web 1 shown essentially consists of a transport device 2, which has two transport strands 2a, 2b, which fix the edges 1a, 1b of the web and transport the web, a winding device 3, to wind the treated web to a winding 4 and means 5 for traversing the web.
  • the transport strands 2 a, 2 b are each guided circumferentially via an inlet-side and an outlet-side deflecting device 2 c, 2 d or 2 e, 2 f.
  • the two transport strands are formed circumferentially in a horizontal plane. In the context of the invention, however, the transport strands can also circulate in a vertical plane.
  • the means 5 for traversing the web 1 cause a reciprocating displacement of the two outlet-side deflection 2e, 2f transversely to the transport direction 6 of the web 1.
  • the two extreme positions of the displaced deflection devices are shown in solid or dashed lines.
  • the reciprocating displacement of the two outlet-side deflection causes a corresponding reciprocal displacement of the edges 1a and 1b of the web 1, so that the edges of the web on the winding 4 not superimposed, but laterally offset from each other come to rest and thereby Thickening of the coil in the edge region opposite the center can be avoided.
  • each deflection device 2e, 2f has an associated drive motor 2g or 2h.
  • both deflection devices are driven by a common motor.
  • the means 5 for traversing the web have at least one lifting device 5a in order to effect the displacement of the two deflection devices 2e, 2f.
  • each of the two outlet-side deflection devices 2e, 2f is each equipped with a separate lifting device, wherein a synchronous operation would be ensured.
  • a common lifting device is preferred, wherein the two outlet-side deflection devices 2e, 2f are interconnected via suitable guides and connecting elements for joint adjustment.
  • the means 5 for traversing the material web can in particular be driven electrically, pneumatically or hydraulically.
  • the lifting device itself may have, for example, an eccentric drive. Depending on the design, it may be advantageous if the stroke length and thus the displacement of the web 1 transverse to the transport direction, is adjustable.
  • a control device 8 is provided, which is in communication with the transport device 2, in particular the or the drive motors 2g, 2h and / or the winding device 3 to the means 5 for traversing the web 1 as a function of the transport speed and / or the diameter of Wickels 4 and / or to control the speed of the winding. If the winding 4 still has a small diameter, it requires a greater speed with which the material web is changed transversely to the transport direction, while a larger winding diameter requires a smaller traversing speed.
  • the traversing of the web takes place already in an area in which the web is still detected in the region of its edges by the transport device 2, so that the distance a between a take-off roll 9 and the winding device 3 is significantly reduced compared to conventional designs.
  • the formation of warping of the textile material web 1 can be largely avoided, in particular with knitwear equipment.
