Definitions

  • the invention relates to an arrangement for winding a material web, in particular Reifencordgewebebahn, with a sleeve-like, can be displaced by a shaft coupling to him winding body, on which the material web is wound, and based on a clamping force holding mechanism to an edge of the wound web to Start the winding on the bobbin to hold, and application of this arrangement.
  • Such arrangements are used, for example, when producing textile fabrics used to reinforce rubber products such as tires, conveyor belts or hoses and, in the course of their manufacturing process, being pulled from a roll, treated and then rewound with such an arrangement.
  • An example of such a method is the so-called dipping in the production of tire cord fabric, in which the textile reinforcing material is coated with an adhesion-promoting latex layer. This happens at the of the Roll withdrawn material before rewinding.
  • the textile fabric is wetted by a dip or by spraying with a latex suspension, for example, the resorcinol-formaldehyde-latex dip, dried and subjected to a thermo-fixing, and after rewinding the heat-set Reifencordgewebes still subject to a measure to prevent aging processes For example, by wrapping in a light, air and water-impermeable film.
  • a latex suspension for example, the resorcinol-formaldehyde-latex dip
  • a winding body are used for winding tire cord fabrics metal cores, coated with a paper sheath metal cores or cores having a central rectangular opening into which a mating rectangular shaft or adapter is used in positive engagement, which is rotatably driven and the winding body in rotation added.

  • the invention has for its object to further improve an arrangement of the type mentioned in particular with regard to Traumwickelteil and variability.
  • the winding body can be operated for setting the clamping force effected by means of the shaft coupling.
  • the shaft coupling can synergistically take on an additional function.
  • the arrangement is preferred for winding material webs in the form of textile fabrics, in particular textile reinforcing materials such as e.g. Tire cord fabrics are designed, which are suitable for reinforcing rubber products.

  • the winding body has an axial length of at least 50 cm, more preferably at least 100 cm, in particular at least 150 cm.
  • the winding body has a topological structural property, as a result of which its effective diameter is elastically reversibly changeable.
  • effective diameter takes into account the fact that seen in cross section, the outer contour of the winding body in one or more of its ingestible states no longer necessarily correspond to the perfect mathematical circular shape, so that you use the effective circumference of the outer contour / ⁇ as an effective diameter can.
  • the topological structure property lies in the opening of the topology of a closed ring.
  • the sleeve-like body thus has at least partially material weakenings in the form of (radially extending) penetrations of the sleeve. It is preferably provided that the opening extends over the full axial length of the winding body. This leaves For example, achieve that the wound body is axially slit during or after it has received its basic shape. With radial, acting from the inside on the inner surface of the sleeve, outward forces, the sleeve can be bent elastically reversible within an elastic deformation range.
  • the gap width is preferably infinitely adjustable by means of the shaft coupling.
  • this gap width (on the outside of the sleeve) in the unloaded state of the wound body is less than 1 cm, preferably less than 6 mm, in particular less than 2 mm.
  • the winding body is preferably elastic due to its material / material combinations in a deformation region, in that the gap widens by the mechanism described above to preferably more than 6 mm, more preferably more than 9 mm, in particular more than 12 mm, up to a widening of preferably less than 30 mm, more preferably less than 25 mm, in particular less than 20 mm elastically, so that the basic shape reverts to the basic shape after the Aufbiegekraft has been canceled.
  • the bobbin is when coupling (or at its beginning and still of the production of the clamp) to the shaft in this basic form produced before.
  • a holding region of the holding mechanism lies at least partially against the walls of the opening.
  • the clamping of the material web edge takes place between the opening walls and one or more counterparts (s) of the arrangement inserted into the opening.
  • a counterpart in a simplest embodiment would be sufficient, for example, an elongated rod which is inserted from the outside into the gap, wherein the rod preferably has an outwardly tapering cross-section.
  • the inserted into the continuous gap bar by at least 50%, preferably at least 66% of the gap depth (corresponding to the sleeve wall thickness) penetrate, while its outer surface is preferably aligned with the sleeve outer surface. In numbers, this could preferably mean at least a depth of 1 cm.
  • shorter Rods are used, it is preferred that the length of a single rod should be at least 20% of the axial sleeve length.
  • At least one edging of the opening in its direction of extension deviates from an orthogonal to the winding body outer surface, in particular recedes inwards, preferably by more than 3 °, and preferably by less than 15 °, in particular by less than 12 °.
  • the gap shape is thus at least on one side trapezoidal, in particular a total of trapezoidal. This allows in conjunction with a preferred complementary shape of the mold formed counterpart / s a reliable clamping, over which a satisfactory winding is ensured.
  • the material of the wound body in particular multi-ply glued paper preferably more than 70%, in particular more than 90%, and in particular consists thereof.
  • the sleeves may consist predominantly of recycled paper, but also new paper can be used.
  • the adhesive for gluing the paper layers is a natural product, such as dextrin.
  • surface roughness (for application purposes) and color (for identification purposes) can be easily varied and they are printable.
  • the inventive clamping without adhesive also prevents sticking of paper to the tire cord fabric.
  • the radial wall thickness of the winding body is preferably at least 8 mm, more preferably at least 12 mm, in particular at least 15 mm.
  • the combination of the above material selection with this wall thickness is considered sufficient to wind web / sheet of the above weights.
  • the arrangement has an expansion clamping shaft for rotationally fixed coupling to the winding body.
  • pneumatically operated expansion clamping shafts are preferably used in a preferred pressure range between 4 and 10 bar.
  • mechanical expansion waves are conceivable.
  • clamping shafts can be used, in which a comprehensive uniform outer diameter increase occurs during their actuation.
  • the enlargement of the effective diameter by circumferentially spaced clamping bars of which preferably at least 6, in particular at least 8 are provided.
  • the diameter of the expansion clamping shaft in the unexpanded state is preferably in the range between 1 mm and 6 mm, in particular between 2 mm and 4 mm smaller than the inner diameter of the non-elastically stretched bobbin.
  • the length of the radial tensioning path is preferably at least 1%, more preferably at least 2%, in particular at least 3% of the diameter of the unexpanded expansion span shaft, with 5% or even already 4% being sufficient.
  • a drive unit can also be provided, preferably with a torque range between 200 Nm and 800 Nm, in particular 400 Nm to 650 Nm.
  • a clamping bar of the expansion clamping shaft in the rotationally fixed coupled state protrudes into the opening.
  • the structure of the winding body is matched to the dimension of the tensioning strip system that a secure clamping of the material web by means of the counterpart / the counterparts is still guaranteed. It is thus created a driving in the form of a lock against mutual torsions, so that there is no noticeable Abrief on the sleeve inside due to, for example, a slipping of the expansion tension shaft in the winding body.
  • the expansion tension shaft also offers an advantage in a producible frictional connection of the coupling, via which a high degree of round travel of the winding body can be realized.
  • the invention discloses at this point also independently and independently of the nature of the holding mechanism and the shape of the bobbin worth protecting an arrangement for winding a material web, in particular Reifencordgewebebahn with a sleeve-like winding body and an expansion clamping shaft for rotationally fixed coupling to the winding body, wherein the expansion clamping shaft is designed to be introduced into the winding body in an unexpanded state and to provide a rotationally fixed connection with the winding body in an expanded state.
  • a method for winding a material web, in particular of tire cord fabric in which a) an arrangement according to one of the preceding claims is provided, b) the winding body is placed on the expansion tension shaft, c) by expanding the expansion tension shaft the opening of the Winding body widens to a gap of a first circumferential extent, d) introduces the edge of the material web into the gap, and e) by relaxing the expansion tensioning shaft reduces the gap to a second circumferential extent and thereby clamps the material web.
  • step d) in particular that the insertion of the web takes place in the form of a U-loop, within which the or the counterparts are also introduced into the gap.
  • the introduction of the counterparts can be done by appropriate gap widening force-free and especially by hand, but it could also not done (completely) force-free under constitutionalhinzuddling.
  • a reliable winding succeeds with take-up speeds of preferably greater than 25 m / min, preferably greater than 40 m / min, in particular greater than 55 m / min, but also greater than 70 m / min. Due to the high Aufwickellessnesszision enabled by the arrangement according to the invention, but winding can also take place at even higher speeds, namely 120 m / min, even up to or more than 140 m / min, even 160 m / min or higher, preferably not more than 200 m / min is used as take-up speed.
