Definitions

  • Textile fibers that are to be combed are usually fed to a combing machine as wadding in the form of wadding rolls.
  • a cotton tape is produced on a tape winding machine from several stretch tapes and then wound up. Before winding, the cotton is calendered to smooth its surfaces so that the cotton can subsequently be unwound from the winding on the combing machine without any problems.
  • Known tape winding machines contain two rotatable winding rollers which carry a cotton roll during winding and a roller calender arranged adjacent to one of the winding rollers.
  • An arrangement in which four calender rolls are arranged in a row approximately coaxial with one of the winding rolls has proven particularly useful.
  • the calender rolls are pressed against one another with a predetermined force. When pulling in the beginning of a new cotton tape, the force is released, which creates small gaps between the calender rolls.
  • the guide plate should be the beginning of a cotton tape around the bottom of the Kalan guide the roller around in the gap between this calender roller and the next calender roller while the calender rollers are allowed to rotate slowly.
  • the device with the guide plate does not work reliably. In particular, if the guide plate is dirty, it can easily clog between the guide plate and the calender roller.
  • the invention therefore has set itself the goal of providing a method with which the difficulties described can be avoided and the beginning of a cotton tape easily and safely around the inaccessible underside of one calender roll and through the gap between this calender roll and the next Calender roll can be passed.
  • the method according to the invention for drawing in a cotton tape between calender rolls on a tape winding machine is characterized in that a plate, of which at least one front section is curved in a shell-like manner around an axis, with a front edge in the gap between two adjacent ones of the calender rolls are inserted and moved around one of the two rolls into the gap between the latter and a third of the calender rolls and that an initial section of the cotton tape is placed on a flexible sheet and / or cloth sheet material attached to a rear edge of the plate and then the plate and the sheet are moved on until the sheet has passed through the second gap.
  • the invention also relates to an auxiliary device for carrying out the method according to the invention, which auxiliary device is characterized by a plate, of which at least one front section is curved in a shell-like manner around an axis, and a flexible sheet made of film and / or cloth attached to an edge of the plate .
  • Fig. 1 shows a cotton roll 1, which rests on two rotatable winding rollers 2 and 3.
  • a cotton tape 4 shown with a broken line runs through a roller calender before it runs to the cotton roll 1 and is wound thereon.
  • the calender consists of four calender rolls 5, 6, 7 and 8, which are arranged adjacent to the winding roll 2 in a row approximately coaxial to it. In operation, the calender rolls 5, 6, 7 and 8 are pressed against one another by a means, not shown, with a predetermined force.
  • the pressing force is released and the calender rolls 5, 6, 7 and 8 are slightly separated from each other, so that a small gap of, for example, about 3 mm width is created between every two adjacent calender rolls. It can be seen that it is then relatively easy to insert the beginning of the new cotton band from above between the rollers 5 and 6 between the rollers 7 and 8, while the rollers are allowed to rotate slowly. However, it is very difficult to ensure that the beginning of the cotton tape passes between the rollers 6 and 7 from below without aids.
  • auxiliary device shown in Fig. 2 used. This consists of a plate 11 with a front edge 12 and a rear edge 13 and a flexible sheet 14 fastened to the plate 11 at the rear edge 13 and made of film and / or cloth.
  • the plate 11 has a front section 15, which is curved in the shape of a shell around an axis A, and a rear section 16, which is less curved or preferably approximately flat.
  • the radius of curvature R of the front section 15 is approximately the same as or slightly larger than the radius of the calender rolls, in particular the calender roll 6.
  • the front section 15 extends, viewed from the axis A, over a winding ⁇ (in one to the axis A vertical plane measured) of more than 180 o , for example 190 to 230 o , preferably about 210 o .
  • the length d of the rear section 16 is approximately 20 to 70% of the radius of curvature R.
  • the rear section 16 could also be omitted, that is to say have a length of zero.
  • the plate 11 can suitably consist of plastic, for example of polyvinyl chloride with a thickness of about 1 to 2.5 mm.
  • the flexible sheet 14 consists of a film, e.g. Plastic film, and / or cloth.
  • the fabric 14 is, for example, a fabric that is coated on the underside with a plastic film and on the top is covered with protruding, inclined fine bristles or fibers or hooks, which are directed towards the edge 13 of the plate 11. Sheets of this type are known as textile brush covers.
  • the Plate 11 with the leading edge 12 first inserted manually from above between the rollers 5 and 6 and moved around the roller 6 until the leading edge 12 between the rollers 6 and 7 comes up again, as shown in FIG. 3.
  • the plate 11 is somewhat elastic, but in any case sufficiently stiff to ensure that the front edge 12 of the plate 11 inserted between the rollers 5 and 6 always reaches the gap between the rollers 6 and 7.
  • the fabric 14 fastened to the rear edge of the plate 11 is placed over the roller 5, and an initial section of the new cotton tape 4 is placed on the fabric.
  • the calender rollers 5, 6, 7, 8 are then rotated further until the plate 11 has been pushed out completely from the nip between the rollers 6 and 7 and also the fabric 14 with the initial section of the new cotton tape 4 has left this nip, as shown in Fig. 5. If the initial section of the cotton tape 4 detaches from the fabric 14 and falls onto the roller 6, then this does not bother.
  • the auxiliary device is now removed and the initial section of the cotton tape 4 is placed over the roller 7 and inserted between the rollers 7 and 8.
  • the calender rolls are no longer pressed against each other, so that there is again a small gap between the rolls 7 and 8.
  • the cotton tape 4 emerging downward from the gap between the rollers 7 and 8 then runs onto the circumference of the winding roller 2 (FIG. 1) and is taken by it to the cotton roll 1.
