Definitions

  • the invention relates to a winding machine for winding of, optionally longitudinally divided, webs, preferably of Paper webs with the features of the preamble of the claim 1.
  • the sealing of the upper gusset is only required at the ends, but here is the problem to cope with the available sealing surfaces are relatively small, which is a non-contact sealing that is as low as possible difficult.
  • the for the The sealing surfaces provided for the sealing task can only then be positioned when the one to be generated Has reached such a large diameter that the Sealing surfaces between the winding tube guide and one of the Carrier rollers can be pivoted through. This is because the considerable width for large winding diameters of the upper gusset space only from a relatively large winding diameter possible. It also requires swiveling the upper and lower part of the wind box, the division level to the narrowest point between the support rollers to put, which further increases the sealing problems.
  • the aim of the invention is to address the sealing problems to reduce with generic winding machines.
  • Another object of the invention is to relieve pressure of the roll to be produced from one to enable particularly small winding diameters and to improve the winding structure.
  • Another object of the invention is improvement the winding structure by combining carrier rollers with a flexible surface, especially with different ones Resilience of the roller surface and application to achieve the pressure relief principle (airlift principle).
  • Another object of the invention is threading the web to be wound between the support rollers in the winding position with generic winding machines automate.
  • a winding machine is used to achieve the desired goal proposed with the features of claim 1.
  • Fig. 1 there are two axially parallel support rollers TW1 and TW2 with a constant minimum gap G their radial lateral surfaces M1 and M2 rotatably mounted arranged. At least one of the support rollers can be driven.
  • the jacket M1, the first support roller TW1 in the web running direction is more elastically deformable than the jacket M2, which in Web direction of the second support roller TW2.
  • both carrier rollers have the same diameter and are themselves at the same level, but the diameters and height levels may also be different.
  • the first support roller has the larger diameter and the lower axis position. That of the two support rollers, whose from static and dynamic load when Resulting total load the larger of the coils is two support rollers, has that of both support rollers stronger elastically deformable jacket.
  • FIG. 4 the sealing position is solid and the pivoting position with dash-dotted lines Lines shown.
  • a piston / cylinder unit is used for swiveling 22.
  • Fig. 3 results (solid and dash-dotted position the sealing surfaces 14 and sealing plate 19), is thus a Adaptation to the maximum and minimum width of the manufactured Winding, on the end faces RE the sealing surfaces 14 concerns, enables.
  • the lower gusset area between the two support rollers TW1 and TW2 and the lower zone of the upper gusset area are arranged by a fixed, open top Wind box 16 sealed so that in cooperation between this, the two support rollers, the winding and the sealing surfaces 14 a pressure chamber DR is closed on all sides, which at the lower end of the wind box 16 over several Pipe sockets distributed along the width of the roller 25 can be acted upon with compressed air (airlift fluid). Of the Wind box 16 is supported by stationary supports 26.
  • the wind box 16 essentially consists of a base plate 27, which is pierced by the pipe socket 25, from a stationary, essentially circular arc Side wall 28, which leaves a minimal Sealing gap adapted to the shape of the second support roller TW2 and is rigidly attached to the wind box 16, as well as from a Side wall 11, which is essentially the entire maximum Web width of the roll to be produced extends and that about a pivot axis 11A, which is approximately parallel to extends the support roller axes, is pivotable.
  • This side wall 11 is wrapped around the web PB to be wound Carrier roller TW1 leaving a web passage gap free GP can be swiveled sealingly for the winding process (Fig.
  • the desirable stability of the sealing table 18 at the upper ends 17A of the end walls 17 of the wind box 16 is achieved by diagonal struts 31.
  • Baffles 12 extending across the machine width extend the formed by the pivotable side wall 11 Web passage gap GP with widening of the gap in the direction towards the incoming web PB.
  • Pressurized gas nozzles 13 facilitate threading the winding web and its application to the wrapped support roller TW1.
