Definitions

  • the invention relates to a winding carrier consisting of axially aligned webs which are arranged in a uniform distribution over its circular circumference and extend over an upper, smaller radius and a lower, larger radius area.
  • Such generally known winding carriers can be pushed into each other coaxially by a defined part of their height due to their differently dimensioned regions and thereby enable axial compression of yarn packages applied, for example, to the winding carriers, so that a number of coaxially arranged yarn packages can be compressed into a homogeneous yarn column.
  • a winding carrier with parallel to its axis supporting elements which lie on a circular cylinder surface and are attached to only one end ring.
  • this end ring there are slots that are larger than the cross section of the support elements.
  • the support elements are connected to at least one support ring, which adjoins the radially inner longitudinal surfaces of the support elements.
  • this known winding carrier In order to be able to be partially pushed coaxially into a winding carrier of the same design, this known winding carrier must have supporting elements, the radial boundary surfaces of which form the bearing surface for the winding are defined by a circular cylindrical surface.
  • the forcibly cylindrical winding surface has the disadvantage that a winding can easily slip unintentionally from a winding support designed in this way and then cannot be pushed back on. Even during the unwinding process of such a cylindrical winding carrier, the last thread layers of a winding tend to be pulled off simultaneously with the thread running in the axial direction of the winding carrier, and are therefore lost for further processing.
  • Another disadvantage of this known bobbin is to be seen in the fact that the end ring protruding radially outward over the cylindrical winding surface, the slots of which further impair the stability of the bobbin, prevents the formation of a freely accessible thread reserve.
  • a winding carrier known from DE-PS 28 45 053 also consists of rod-shaped support elements which run in the axial direction and form a circular cage with annular support elements.
  • outer surfaces of the rod-shaped support elements form parts of a bi-conical outer surface with a common smaller base circle, the common base circle being in the central region of the winding carrier, this winding carrier does not have the disadvantages described above.
  • the friction roller is subject to a chatter effect, the extent of which depends on the size of the distance between adjacent support elements.
  • this distance cannot be reduced arbitrarily, since the spaces between the support elements have the function of forming passages for a flowing treatment medium.
  • the invention has for its object to provide a winding support that can be inserted into a similarly designed coaxial by a certain amount, which can be manufactured in a simple form, requires a small amount of material, but is still characterized by great stability, from the beginning can be wound on without interference, allows the formation of a freely accessible thread reserve, ensures that an applied winding is prevented from inadvertent displacement, and which can finally be unwound in an orderly manner to the end of the thread without the last thread layers being simultaneously pulled from the winding by the thread running off will.
  • the shell shape which is uninterrupted except for the radial openings, simplifies the shape required for its production in plastic compared to a winding carrier composed of individual rings and rod-shaped support elements.
  • the webs projecting radially outward only over the upper support region can be designed in a simple manner so that their outer radial boundary surfaces lie on radii which decrease slightly in the direction of the lower carrier region, so that these boundary surfaces are parts conical to the upper end of the winding can form a widening changing surface.
  • the webs only protrude radially outward beyond the jacket over the height of the upper support area, but protrude radially inward over the jacket over the height of the lower support area, there is a continuous except for the radial jacket openings, which preferably consist of circular holes smooth outer surface against which a friction roller for driving the winding support can be pressed without being exposed to a chattering effect during the winding process. Since the diameter of the openings in the jacket is considerably smaller than the width of the conventional friction roller, it is continuously supported as the winding carrier rotates before the first thread layers are wound up.
  • the circumferential continuous support of the first thread layer on the lower carrier area also favors sufficient adhesion against simultaneous sliding of the last thread layers during the unwinding process.
  • the formation of the lower carrier region without supporting parts projecting radially outward beyond the jacket favors the arrangement of a thread reserve which is always freely accessible in order to be able to connect the thread end of a winding with the thread beginning of another winding at an early stage.
  • the upper web ends of a winding carrier comb when sliding coaxially into an equally designed winding carrier with its lower web ends.
  • the end faces of the upper web ends of one winding carrier abut against the end windings of the winding located on the other winding carrier and compress this winding with coaxial compression.
  • the combing effect between the webs of both winding carriers prevents the lower thread layers from participating in the compression and instead getting into the annular space created by the parts of the winding carrier pushed into one another. To prevent this, however, it is not necessary to adapt the cross section of a gap between two adjacent webs to the cross-sectional shape of the webs.
  • the webs on the upper support area have outer radial delimitation surfaces that lie according to the invention on a radius that is smaller than the inner radius of the casing in the lower support area
  • the webs on the lower support area have inner radial delimitation surfaces that lie according to the invention on a radius, which is larger than the outer radius of the jacket in the upper carrier area
  • identical winder carriers can be pushed coaxially into each other in almost any angular position, whereas only the position in which the webs of one winder carrier are aligned with the webs of the other winder carrier can be prevented.
  • the degrees of freedom that are thus wide in terms of angle for pushing the winding carriers into one another allow generous tolerances with regard to the winding carrier shape, which makes the manufacture of the winding carriers cheaper and moreover makes their handling very easy.
  • the carrier regions can be cylindrical or the upper carrier region tapered in the direction of the lower carrier region and the lower carrier region in the direction of the upper carrier region, so that a biconical contact surface is created for the winding to be applied, which favors its axial displaceability and nevertheless prevents the winding from slipping unintentionally from the winding support.
  • windings applied to the continuous, jacket-like, closed contact surface of the lower carrier area already exert a large retention force on the lower thread layers of a winding.
  • the upper carrier region can therefore also be cylindrical without the risk of the winding slipping as a whole or its lower thread layers.
  • a preferred embodiment of the invention provides for connecting the upper and the lower support area via a central support area which is conically tapered in the direction from the lower to the upper support area.
  • This configuration also makes it possible to realize winding carriers which consist of two essentially cylindrical carrier regions which have the diameter differences required for pushing two identical winding carriers into one another, these differences being completely compensated for by the central carrier region.
  • the webs of the lower and upper support legs are preferably sufficient range up to the middle area of the beam, its height tapering to zero over the height of the middle area of the beam.
  • the web path penetrates the winding support jacket in the central region or the beveled ends of the webs projecting radially outwards and the bevelled ends of the webs projecting radially inwards lie opposite one another.
  • a definite limitation of the amount by which a winding carrier should be insertable into another winding carrier of the same design can be accomplished according to a further embodiment of the invention in a particularly expedient manner in that the radially inwardly projecting webs hm area of the middle carrier area on their radial boundary surfaces are stepped and an end portion of each web has a radial boundary surface which is on a smaller radius than the outer diameter of the upper support region.
  • the upper end face of the winding carrier jacket abuts the steps formed in the webs and thus prevents the winding carrier from penetrating beyond.
  • an embodiment of the invention provides that the lateral distance between adjacent webs is greater than three times the thickness of the webs.
  • the sleeve-shaped winding carrier essentially consists of an upper carrier region 1, a lower carrier region 2 and a middle carrier region 3.
  • the carrier regions 1, 2 and 3 are formed from a continuous jacket 5 which, apart from openings 6 which are distributed uniformly over its circumference and its height closed is.
  • the jacket 5 is cylindrical or tapered slightly towards the central support part 3, while the central support area 3, as a connection between the support areas 1 and 2, is markedly conical.
  • the outer diameter of the upper carrier region 1 is smaller than the inner diameter of the lower carrier region 2.
  • axially extending webs 7 are arranged on the upper carrier region 1, which project radially outward beyond the jacket 5, and axially extending webs 8 are also arranged on the lower carrier region 2, which extend radially inwards project the coat 5.
  • the webs 7 and 8 extend over the central conical support area 3 and each run out in the edge direction of the support area 3.
  • the webs 7 have radially outer boundary surfaces 9 which lie on a smaller diameter than the inner diameter of the jacket 5 within the lower carrier region 2.
  • the webs 8 have radially inner boundary surfaces 10 which lie on a larger diameter than the outer diameter of the jacket 5 within of the upper carrier area 1.
  • the radially outer boundary surfaces 9 of the webs 7 are in any case of a larger diameter than the radially inner boundary surfaces 10 of the webs 8.
  • the webs 8 are formed in a stepped manner within the central carrier region 3 in such a way that an upper end piece 11 of the webs 8 each has a radial inner boundary surface 12 which is of a diameter which is smaller than the outer diameter of the jacket at the upper end of the winding carrier.
