Definitions

  • the invention relates to a bobbin for receiving yarns and the like with a thread reserve area and with a substantially cylindrical, formed by cage-like support elements formed jacket surface, which has a closed end ring with a radially inner cover surface at one end and a closed upper ring at its other end with an axially projecting collar.
  • a lower end ring which has a thread reserve groove on its radially outer surface.
  • This end ring has a centering receptacle in which a centering projection of an axially adjacent winding carrier can engage. The interaction of the centering receptacle of one and the centering shoulder of the adjacent winding carrier thus creates a sealing coupling between two winding carriers, which prevents the dye liquor from passing through in the region of the adjacent winding carriers.
  • This known winding carrier which is advantageous for many applications, has the disadvantage that the thread reserve located in the thread reserve groove is covered with axial compression of the winding located on winding carriers arranged one above the other and can therefore no longer be found or can only be found again during subsequent processing.
  • the object of the present invention is to design a bobbin, which can be a rigid or axially and / or radially compressible bobbin, in such a way that the thread reserve is columnar one above the other even in the event of axial displacement of the associated bobbin, in particular with axial compression arranged winding, always remains freely accessible,
  • This winding support is particularly suitable for assembling yarn packages in a column-like manner on a dyeing sword or spear, in which case the dyeing liquor is then passed through the jacket wall of the winding support and the packages located thereon.
  • the individual coils can come into direct contact with one another and thus form a column whose density and thus also the flow resistance are homogeneous over the entire length.
  • Such compression can also be done alone or in addition to the purpose of simplifying the unwinding of the winding, by reducing the crossing angle generated during winding by axial compression of the winding, so that the thread is only relatively slightly displaced in the axial direction during unwinding .
  • the jacket with the jacket surface formed from it can be designed in many different embodiments.
  • the jacket can be in one piece and rigid.
  • a one-piece jacket comes into consideration, which can be compressed axially and / or radially.
  • the jacket can also consist of two parts, so that it can be pressed together in the axial direction. Even with such a two-piece jacket, radial compression is possible alone or in addition.
  • the winding support according to the invention can be designed such that the federal government is provided with a thread reserve groove. This results in a specially protected, precisely defined storage for the thread reserve.
  • the winding carrier according to the invention can also be designed such that the end ring has a thrust ring surface projecting radially outward beyond the outer surface of the winding carrier. This ensures that a winding drum only acts on this end ring during winding and not on the elements of the outer surface forming the winding surface and the first layers of yarn wound thereon.
  • the winding carrier according to the invention can also be designed such that the radially outer outer surface of the upper ring is adapted to the outer surface. This can result in particular advantages in terms of molding technology.
  • the winding support according to the invention can also be designed such that the axial width of the collar of the upper ring is greater than or equal to the width of the cover surface of the end ring. In this way, there is a gap between the collar on the one hand and the end ring on the other hand, through which a yarn thread can be guided from the thread reserve to the winding, which cannot be destroyed when the winding carriers and sleeves are axially compressed.
  • the winding carrier according to the invention can also be designed such that the cover surface is delimited by a radially inwardly projecting shoulder. In this way, a exact dimensions are specified by which the collar of a winding carrier engages in the end ring of an axially adjacent winding carrier.
  • the winding support according to the invention can also be designed such that the collar is delimited by an annular shoulder projecting radially outwards. In this way too, the assignment of two adjacent winding carriers can be determined exactly.
  • the winding carrier according to the invention can furthermore be designed such that the cover surface is divided into an axially outer cover section and a guide section which is offset radially inward and the radial outer dimensions of the federal government are at least in its most axially projecting part the same or smaller than / than those of the guide section. In this way, a precise axial guidance of adjacent winding carriers is ensured without impairing the accommodation of the thread reserve in any way.
  • the winding support according to the invention can also be designed such that the end ring is provided with ribs which extend evenly over the circumference from the cover surface and whose inner surfaces extend radially inwards onto an enveloping surface.
  • These rib approaches can be used to guide nested winding supports and be beveled in a suitable manner to facilitate insertion. They can also be used to limit insertion.
  • the winding support according to the invention can also be designed such that the upper ring is provided with projections running in the axial direction over a part of the collar and evenly distributed over the circumference, the outer surfaces of which extend into an enveloping surface, the radial dimensions of which are the same or smaller than / than those of the cover area.
  • the thread reserve is on the bundle before the approaches.
  • the winding support according to the invention can also be designed such that the axial extent of the shoulders of the upper ring is smaller than the axial extent of the ribs of the end ring.
  • the winding support according to the invention can be designed such that the number of the approaches of the upper ring is equal to that of the rib approaches of the end ring.
  • 1-3 has an end ring 1 at one end and an upper ring 2 at its other end. Between these two rings 1, 2 there is a jacket 3 with a jacket surface 4 onto which yarn in the form of a Wikkels not shown can be wound up.
  • the jacket 3 shown in dash-dotted lines in FIG. 1 can be designed as a unit which is essentially rigid or else axially and / or radially compressible.
  • the end ring 1 has a thrust ring surface 5 which is cylindrical in the exemplary embodiment and is offset radially outward with respect to the outer surface 4.
  • the inside of the end ring 1 is essentially delimited by a cover surface 6, which is divided into a cover section 7 and a guide section 8.
  • the cover section 7 lies on the axially outer end of the cover surface 6.
  • This cover section 7 is followed radially inward by the guide section 8, which is adjoined by an inwardly projecting shoulder 9.
  • rib projections 10 are provided which are evenly distributed over the circumference.
  • the rib extensions 10 increase in their radial extension in the direction of the shoulder 9. They have a rounded corner 11.
  • the upper ring 2 at the other end of the winding carrier has an outer surface 12 which lies in the outer surface 4. After a shoulder 13, this outer surface 12 is followed by an axially protruding collar 14 with an outer diameter that is reduced compared to the outer surface 12.
  • Axially extending projections 15 project beyond the shoulder 13 and only extend over part of the width of the collar 14.
  • the outer diameter of the collar 14 is at most equal to that of the smallest envelope surface on which the radially inner edges of the rib extensions 10 extend.
  • the collar 14 also has a thread reserve groove 16 with a further reduced outside diameter.
  • the rib lugs 10 and the lugs 15 are evenly distributed over the circumference.
  • the number of rib extensions 10 corresponds to that of the extensions 15.
  • the axial length of the rib extensions 10 is greater than that of the extensions 15.
  • the collar 14 of a winding carrier of the type described can be inserted into the end ring 1 of an axially adjacent winding carrier, the lugs 15 each coming to lie between the rib lugs 10.
  • the collar 14 extends into the guide section 8 of the end ring 1 and abuts the shoulder 9 there.
  • a thread reserve can be accommodated in the thread reserve groove 16, from which a thread can be guided between the extensions 15 and the rib extensions 10 to the winding , which is located on the winding support.
  • FIG. 4 shows the end ring 1 of an (upper) winding carrier and the upper ring 2 of a (lower) winding carrier.
  • This figure in particular makes it clear that, in the stacked position, the collar 14 abuts the shoulder 9 of the end ring 1 with its free end.
  • the thread reserve groove 16 of the collar 14 is covered by the end ring 1, a gap remaining between the axially outer end of the end ring 1 on the one hand and the shoulder 13 or the outer surface 12 of the upper ring 2, through which a thread extends from the thread reserve groove 16 to can be performed a winding, not shown, which is formed on the lateral surface 4 or is arranged there.
  • FIG. 1 shows an embodiment of the winding support according to the invention, which has a jacket 20 which has rings 21 which are connected to one another by struts 22 inclined to the axial direction.
  • This jacket 20 results in an essentially rigid winding carrier with an end ring 1 and an upper ring 2 according to FIGS. 1-4.
  • the embodiment of the winding carrier according to the invention shown in FIG. 6 differs from that according to FIG. Only in that between the rings 21 approximately S-shaped struts 26 are arranged, which deform when an axial pressure is exerted on the winding carrier and thus axially the winding carrier make compressible.
  • the winding support according to FIG. 1 also has an end ring 1 and an upper ring 2, as described with reference to FIGS. 1-4.
  • Fig. 7 shows a two-part winding carrier with an end ring 1 and an upper ring 2. From the end ring 1, axially parallel rod-shaped support elements 30 extend, which are connected at their ends via predetermined breaking points 31 to an internal locking ring 32. A foot part 33 of the winding support is thus formed.
  • the head part 34 has a head part 34 with an upper ring 2, from which support elements 35 extend, which are connected to a support ring 36 at their inner edges in the area of the axial center of the winding support.
  • the support ring 36 engages in the locking ring 32.
  • the support elements 30 and 35 form a jacket 37.
  • the jacket 37 can also be radially compressible.
  • Thermoplastic material which can be used in the desired color, is particularly suitable for producing the winding support according to the invention in its various embodiments.
