Definitions

  • the invention relates to a method for winding a moving material web, in particular a paper, cardboard, tissue or another fibrous web, in which the web is successively wound onto a plurality of winding cores to winding rollers, wherein the web over a peripheral region of, with a new Winding core or a winding roll a winding nip forming carrier drum is guided.
  • the invention also relates to capsules for carrying out the method.
  • Such winding and winding machines are used, for example, in paper or board making, the finished and running paper or board web without interrupting the manufacturing process, that is, without switching off the paper or board machine, successively to several hubs, which are also referred to as reels, to wind up bobbins.
  • hubs which are also referred to as reels
  • they can serve to wrap an already wound wound roll.
  • the full winding roll is moved away from the carrier drum at the resolution of the winding nip and in the formation of a free train in the web before the beginning of the transfer of the web and brought a new hub to the carrier drum in forming a new winding nip. It must be ensured that the new beginning of the material web resulting from the severing of the material web is fed to the new winding core, in order to subsequently form a new winding roll thereon.
  • the tail should be fixed on the full hub to avoid that it comes to shred and the wrapping of shreds in the new winding roll.
  • the use of double-sided adhesive tapes for fixing is known, for example, from European Patent EP 1 035 054 B1.
  • the object of the invention is therefore to make the fixation of the material web safer and easier.
  • this object is achieved in that at least one capsule containing an adhesive medium is introduced into the gap between the material web and the winding core or winding roll by means of a sheathing which encloses the adhesive medium and can be broken in the winding nip.
  • the supply of the adhesive medium in the form of capsules is much easier, since in this case neither the viscosity of the medium nor the pollution play a special role.
  • the casing of the capsules can be designed so that it already bursts when hitting the material web and / or the winding core.
  • the sheath after tearing the adhesive, preferably liquid medium free, so that the tail is fixed to the winding core or on the full winding roll.
  • the sheath should be formed of a flexible material, in particular of a plastic film.
  • the sheath consists of a biodegradable material, preferably paper or corn starch.
  • One way of introducing a capsule in the winding nip is the direct shooting of a point above the material web, wherein the acceleration is generated for example by means of compressed air or spring force.
  • the capsule into the gap between material web and winding core or winding roll so that the capsule reaches the winding nip on a ballistic trajectory.
  • a third possibility for introduction is the dropping of the capsule into the gap between material web and winding core or winding roll. Since only the weight force is used, the feeding point of the capsule must also be placed exactly above the point of use in the winding nip.
  • the feeding point of the capsule may be offset horizontally to the point of use when shooting or dropping.
  • delivery is generally easier when the capsule is introduced into the gap from a point above the web.
  • the capsules should be introduced into the gap in the middle area and / or at the side edges of the material web.
  • the introduction in the middle is generally used to attach the winding start on the winding core.
  • the introduction at the side edges is often important for attaching the tail to the full winding roll.
  • FIG. 1 shows a schematic side view of a winding machine during the main winding phase
  • Figure 2 is a schematic side view of a winding machine during Endwickelphase with open winding nip 4 to the full winding roll 3 and

  • the winding machine shown in Figure 1 is used for winding a moving material web 1, wherein the material web 1 is successively wound on a plurality of winding cores 2 to winding rollers 3.
  • the material web 1 may in particular be a fibrous web, such as a paper, board or tissue web, for example.
  • the winding machine comprises a carrier drum 5, also referred to as a pressure drum or support roller, which is either rigidly mounted or displaceable along a horizontal straight line 7 by means of a pressing device (not shown) and driven by a drive.
  • the carrier drum 5 may have a closed, rubberized, grooved and / or drilled surface in a known manner.
  • the various types of storage and movement for the carrier drum 5 are disclosed in particular in the German patent application DE 198 07 897 A1; its content is hereby made the subject of this description.
  • the material web 1 is led out either from a calender not shown here or from a likewise not shown here dryer section of a paper or board machine. It then wraps around first a spreading roller, not shown, then runs in the direction of arrow on the lateral surface of the carrier drum 5 and wraps around this lateral surface by a certain angle ("peripheral region") until it is detached by the wound roll to be formed.
  • a spreading roller not shown
  • the detachment of the material web 1 from the carrier drum 5 and the transfer to the winding roll 3 to be formed takes place in the so-called winding nip 4, which forms during the main winding phase between the carrier drum 5 and the winding roll 3 to be formed.
  • the winding roll 3 to be formed is guided by means of a not shown lifting or pressing device of a movable transport device in the direction indicated by the arrow 8 direction of movement.
  • the lifting device can be, for example, at least one spindle drive, which comprises a threaded spindle driven by a motor unit, or at least one actuator in the form of a linear drive or a hydraulic cylinder.
  • the transport device serves to hold and guide the winding core 2 resting on the rails 9 of the winding roll 3 to be formed.
  • a device for regulating the line force arising in the winding nip 4 during the main winding phase is disclosed, for example, in the already cited German Offenlegungsschrift DE 198 07 897 A1.

  • the Lucasabquetschwalze 10 is applied only when reaching a desired layer thickness by means of at least one not shown moving means to be formed to the winding roll 3.
  • the Lucasabquetsch can of course also be designed as a brush, a Foil, a roller arrangement or the like.
  • the squeegee roller 10 may be movable by generally known mechanisms both substantially linearly, preferably horizontally and / or vertically, as well as substantially along a contour of a circle segment.
  • Figure 2 shows a schematic side view of a winding machine with the Lucasabquetschwalze 10 during Endwickelphase.
  • the axis of rotation of the new winding core 2 thus lies substantially in a horizontal straight line 7 containing the axis of rotation of the carrying drum 5.
  • a loading device is provided which, at least during the separation of the material web 1 from a point 6, introduces several capsules containing an adhesive medium into the closing gap between the material web 1 and the new winding core 2 or the full winding roll 3.
  • the capsules have a, the adhesive medium enclosing sheath of paper or corn starch, which ruptures upon entry into the winding nip 4 and thus releases the adhesive medium.
  • the capsules may for example have the shape of spheres, cuboids, tetrahedrons.
  • the introduction of the capsules can be done in different ways.
  • the capsules are injected via a feeding device from a central point 6 approximately in the region of the web center directly into the closing gap between the material web 1 and the new winding core 2. This ensures that the new beginning of the material web 1 is transferred to the new winding core 2.
  • the capsules are accelerated by means of compressed air or spring force and directed to the web center and the side edges of the web 1.
  • the feeder must be positioned directly above the location where the adhesive is to be supplied. After separating the material web 1, the tail is so securely fixed to the full winding roll 6 via the adhesive medium, so that a ragged flight is avoided.
  • the new winding core 2 can be placed on the rails 9.
  • FIG. 5 furthermore shows the possibility of feeding capsules into the gap between the material web 1 and the new winding core 2 for the purpose of fixing the web start on the winding core 2 by injecting the capsules into this new winding gap 4.
  • the capsule can also be inserted according to Figure 4 in the closing gap between the web 1 and the full winding roll 3 and between the material web 1 and the new hub 2, for example, from a common feeder.
  • the capsules thus follow a ballistic trajectory.
  • the injection and insertion of the capsules can also be done from a point 6 side of the web 1 from.
