Definitions
- the invention relates to a winding carrier consisting of two core parts with a substantially cylindrical outer surface for receiving a yarn package, each core part having cage-like support elements running in the axial direction of the core carrier and the two core parts being axially insertable.
- both sleeve parts are provided with a radially outwardly projecting end ring. It is particularly disadvantageous that in this known winding carrier no thread reserve can be formed, which is still freely accessible even after the winding carrier and the winding located thereon have been compressed.
- the invention has for its object to form a bobbin of the type mentioned so that it allows the formation of a freely accessible thread reserve even with axial compression.
- a winding carrier of the type mentioned above in that the axially outer end of only one of the sleeve parts is provided with a circumferentially closed thrust ring which has a thrust ring surface projecting radially outward beyond the winding surface formed by the supporting elements and on its radially inner edge has a cover surface and a guide surface which is offset further radially inwards, and that at the axially outer end of the other sleeve part there is provided an annular body which projects radially inwards with respect to the winding surface and projects axially beyond the support elements, the outer surface radius of which is equal to or slightly smaller than the radius of the guide surface of the thrust ring.
- the thrust ring projecting radially outward beyond the winding surface ensures that the winding drum only acts on this ring during winding and not on the support elements forming the winding surface and the first layers of yarn wound thereon.
- a secured thread reserve can be accommodated on the ring body, the entire length of which is completely exposed and cannot be moved or damaged.
- winding carriers are axially nested, as is usual with axial compression, then the ring body of one winding carrier engages in the thrust ring of the axially adjacent winding carrier, the outer surface of the ring body cooperating with the guide surface of the thrust ring.
- the cover surface of the thrust ring covers a further part of the outer surface of the ring body. In this covered area of the ring body, a thread reserve can thus be accommodated, which is completely protected when such winding carriers are axially interlaced and is consequently freely accessible after axial compression and after the winding support column has been dissolved into individual winding carriers.
- 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 only relatively slightly displaces in the axial direction during winding .
- the winding support according to the invention can also be designed so that the cover surface and the guide surface of the thrust ring run coaxially. While the guide surface aligns two axially adjacent winding carriers with each other, the cover surface provides a protected space for accommodating the thread reserve.
- the winding support according to the invention can also be designed such that the end sections of the support elements carrying the ring body end radially at the outer surface of the ring body at a radial distance therefrom. In this way, an undisturbed thread transition from the thread reserve to the winding is ensured.
- the winding support according to the invention can also be designed such that the end of a sleeve part lying in the region of the longitudinal center is connected to a locking ring which is connected via predetermined breaking points to radially inner surfaces of the support elements, while the ends lying in the region of the longitudinal center of the winding carrier Support elements of the other sleeve part sit firmly on the outer surface of a support ring and the locking ring and the support ring come into axial contact with one another.
- the locking ring defines the axial length of the sleeve before compression. If a limit value for the axial pressure is exceeded, the locking ring releases from the support elements and slides with the support ring in the direction of the thrust ring. Locking ring and support ring contribute to a radial stiffening of the winding carrier.
- the lock ring can provide a guide that works with a dyeing sword or spear.
- the winding support according to the invention can be designed so that the locking ring has a receiving portion which is offset radially inward with respect to the supporting elements carrying it, and that the support ring in the space between the Receiving section and engages the supporting elements carrying them.
- the support ring engages in a kind of ring groove, which is defined by the locking ring and the supporting elements carrying it. This creates a clamp connection, which releasably fixes the two sleeve parts together.
- the support ring can thus be fixed in the starting position of the winding carrier with the required security.
- the winding support according to the invention can be designed such that the two sleeve parts are connected to one another via the locking ring and the support ring in the manner of a snap connection. If the sleeve parts are inserted into one another, then they can only be detached again with the application of force.
- the snap connection can be formed in a variety of ways in that at least one projecting section of one sleeve part resiliently engages over a projecting section of the other sleeve part or engages in a recess of this other sleeve part.
- the winding support according to the invention can be designed such that the support elements are flexible in the direction of the longitudinal axis of the winding support. This flexibility, which can be achieved through material selection, dimensioning and construction, makes it possible to follow a shrinkage of the yarn reel if corresponding pressures directed radially inward occur.
- the winding support according to the invention can finally be designed such that the ring body, the locking ring and the support ring are flexible in the direction of the longitudinal axis of the winding support. This flexibility, which can be achieved through material selection, dimensioning and construction, also contributes to the shrinkage of the yarn reel when corresponding radially inward pressures occur.
- cylindrical used here also includes deviations from a purely mathematical cylindrical shape, which result in particular from the shrinking behavior of the materials used and from the requirements of the demolding processes.
- the winding support according to the exemplary embodiment shown in the figures has a lower sleeve part, which is referred to below as foot part 1, and an upper sleeve part, which is referred to below as head part 2.
- foot part 1 is to be described in particular with reference to FIGS. 1, 7 and 8.
- the thrust ring 3 has a thrust ring 3 at the axial end, which also forms one end of the entire winding support.
- This thrust ring 3 forms a thrust ring surface 4 on its radially outer surface, which runs closed over the entire circumference.
- the thrust ring 3 On the radially inward-facing side of its cross-section, the thrust ring 3 has a cover surface 5 which extends from the end of the foot part 1 and is delimited by a shoulder 6.
- An essentially cylindrical guide surface 7 adjoins this shoulder 6 with respect to the cover surface 5, offset radially inwards. This is delimited by an inwardly projecting shoulder 8, which leaves a passage opening 9 free.
- the thrust ring 3 is adjoined by support elements 11 which run essentially parallel to the axis 10 of the foot part 1 and whose radially outer edges 12 define a cylindrical winding surface.
- the support elements 11 are evenly distributed over the circumference of the foot part 1 and have side surfaces 13 which run parallel to one another and are directed essentially radially with respect to the axis 10. They have radially inner edges 14 which diverge in the direction of the thrust ring 3 for demolding reasons.
- a locking ring 16 is provided near these ends of the support elements 11 and is connected via predetermined breaking points 17 to the inner edges 14 of the support elements 11. In its cross-section, this locking ring 16 has a pressure shoulder 18 adjoining the predetermined breaking points 17 and subsequently an essentially cylindrical receiving section 19 which merges into a ring section 20 pointing radially inwards, which leaves a central opening 21 open.
- the upper sleeve part, ie the head part 2 will now be described in particular with reference to FIGS. 1, 5 and 6.
- the winding carrier At the end, which forms one end of the winding carrier, it has an annular body 25 with an outer surface 26, which is followed by an annular section 27 running normally to it.
- Support elements 28 extend from the ring body 25 and run parallel to the axis 29 of the head part 2.
- the support members 28 are even over the order beginning of the head part 2 distributed and have outer edges 30 which define a cylindrical winding surface.
- the outer edges 30 At the end, which, when the winding support is assembled, lies in the area of its longitudinal center, the outer edges 30 have a slope 31 that slopes toward the axis 29.
- the support elements 28 also have a section 32 which extends beyond the ring section 27 and ends at a radial distance from the outer surface 26.
- the support elements 28 also have radially inner edges 33 which diverge in the direction of the ring body 25.
- a support ring 34 is attached to the inner edges 33 of the head part 2, which has a stimulating section 35 and then an end section 36 of lesser wall thickness.
- the foot part 1 and the head part 2 are initially each made individually, in particular from plastic. Subsequently, these two parts are aligned with aligned axes 10 and 29, the end section 35 of the support ring 34 of the head part 2 coming to rest on the receiving section 19 and on the pressure shoulder 18 of the locking ring 16. An annular projection 40 of the end section 35 then engages in a groove 41 in the receiving section 19, so that a snap connection is formed which holds the two sleeve parts 1, 2 together and can only be released with the application of force.
- the support elements 11 of the foot part 1 each lie between two support elements 28 of the head part 2.
- the winding support can be spooled in the usual way, that is to say can be provided with a winding (not shown).
- a thread reserve can be formed on the outer surface 26 of the ring body 25 near the ring section 27, from which the thread runs between two sections 32 to the rest of the winding.
- Winding carriers wound in this way can now be arranged axially one above the other, the ring body 25 of a winding carrier cooperating with a guide surface 7 of an axially adjacent, identical winding carrier.
- the cover surface 5, which protrudes radially outward relative to the guide surface 7, covers the thread reserve present on the outer surface 26 of the ring body 25.
- axial compression can now take place, in which the foot part 1 and head part 2 of each winding carrier are pushed into one another in the axial direction.
- the maximum possible compression of these two parts is shown in Fig. 3.
- the bobbins are also axially compressed, with all bobbins forming a continuous column of yarn.
- the thread reserve accommodated on the outer surface 26 is in no way affected. It is therefore freely accessible when the individual winding carriers become separated from one another again after compression.
- the axial compression of the packages and thus the formation of a homogeneous yarn column leads to the same flow conditions for a dyeing liquor which is pressed through by the packages.
- the axial compression of the. Winding also has the effect that the crossing angle of the yarn that occurs when the winding carrier is wound is changed by the individual thread turns forming a larger angle with the axis of the winding carrier, so that the thread is only displaced in the axial direction by a reduced amount becomes.
- the central opening 21 of the locking ring 16 can be used as a guide on a dye spear or sword, not shown.
- the thrust ring surface 4 of the thrust ring 3 has a slightly larger diameter than the cylindrical winding surface, which is formed jointly by the outer edges of the support elements 11 of the foot part 1 and the head part 2.
- the winding support can therefore be set in rotation for winding by a non-positive rolling of a starting drum on this thrust ring surface 4.
