Definitions
- a textile-treating sleeve made of thermoplastics material has a cylindrical or conical shell comprising consecutive rows of rigid ring sections. These ring sections extend circumferentially and are spaced apart in the axial and transverse directions. The ring sections of adjacent rows are offset relative to one another, and the ends of ring sections of adjacent rows are connected by longitudinal webs which are elastically and plastically yieldable in circumferential direction when axial and/or radial pressure is applied to the sleeve.
- the invention relates to a textile-treating sleeve, preferably of thermoplastic material, having a cylindrical or conical shell for the heat and/or wet treatment of yarns or threads.
- the yarns or threads are usually wound on sleeves and are subjected to the heat and/or wet treatment in this state.
- the heat treatment may be a shrinking process, and the wet treatment a dyeing process.
- the sleeves undergo, simultaneously with their axial compression, also a reduction in their diameter, and vice versa, when they are radially compressed, a simultaneous reduction in the axial direction.
- One of these applications is the treatment of texturated yarns, such as, e.g. the curled yarns sold under the trade name Helanca.
- the yarns are wound on the sleeves in a more of less stretched, tensioned state.
- the sleeves are then axially compressed together with the yarn, the yarn tends to expand radially outwardly as well as radially inwardly.
- the inner layers of the yarn tend to be more strongly compressed than its middle and outer layers, resulting in different results of the treatment within the-wound yarn, such as nonuniform dyeing and changes in the curl, which are undesirable.
- Textile-treating sleeves preferably of thermoplastic material, have already been proposed for these applications, in which an axial compression is accompanied by a positive reduction of the diameter-and, vice versa, a radial compression by a reduction in the axial direction.
- One such sleeve comprises a shell having, in uniform distribution, elements which yield in both diagonal directions elastically and/or plastically, and rigid diagonal webs connecting these yielding elements.
- Another proposed sleeve is characterized in that the shell has peripherally extending, spaced apart, axially elastically and/or plastically yielding rings and rigid longitudinal webs connecting the rings and arranged in spaced apart relationship, wherein axially consecutive longitudinal webs are laterally offset relative to each other.
- the invention has the object of providing a textile-treating sleeve which is characterized by particularly good operation, and that especially insofar as it offers'a very good support for the yarns or threads to be wound thereon, and as it maintains to a far extent its cylindrical shape without distortion or twisting in its compression.
- the application of suitable pressures and temperatures will cause an elastic and/or plastic deformation of its yielding longitudinal webs.
- the sleeve is made of thermoplastic material, for example polypropylene, its longitudinal webs will yield elastically at room temperature, and elastically as well as plastically at higher temperatures.
- the sleeve offers a very good support for yarns and threads to be wound thereon. Furthermore, the type and arrangement of the ring sections and longitudinal webs ensures that the sleeve maintains under compression to a far extent its cylindrical shape, without bending or twisting.
- the ring sections and the longitudinal webs are equidistantly spaced from one another and the ring sections of axially consecutive rows of rings are offset relative to each other by half their axial spacing. This arrangement results in uniform distribution of the ring sections and longitudinal webs over the shell of the sleeve, with beneficial effects on its operation.
- thelongitudinal webs may be inclined relative to the axial direction, and the inclination of the longitudinal webs connected on one end portion of each ring section is opposite to that of the longitudinal webs connected on the other end portion of said ring section.
- This inclined arrangement of the longitudinal webs supports the formation of articulated joints at the connecting points between the longitudinal webs and the ring sections and facilitates yielding of the longitudinal .webs under axial or radial compression of the sleeve.
- the direction of inclination of axially consecutive longitudinal webs changes alternately, and two axially consecutive longitudinal webs form an obtuse angle, pointing in the direction of the end of the ring section to which they are connected.
- the longitudinal webs have, at their connecting points with the ring sections, a configuration which provides bending and buckling points.
- This construction provides for yielding of the longitudinal webs by bending and buckling at these points, and further im proves the yielding properties.
- the end portions of the ring sections are connected by a single web each with the ends of the ring sections of axially adjacent rows of ring sections, and wherein the webs connecting adjacent ends of ring sections of axially consecutive rows of ring sections extend continuously from one end of the sleeve to the other.
- the ring sections of axially adjacent rows of ring sections overlap in the circumferential direction, and the overlapping parts of the ring sections are each connected by at least two spaced, parallel longitudinal webs.
- the ring sections when the sleeve is compressed, the ring sections are maintained parallel by the longitudinal webs. This isdue to the fact that the two or more spaced, parallel longitudinal webs form, with the parts of the ring sections to which they are connected, parallelograms and undergo a parallelogram displacement when the sleeve is compressed. In consequence, the sleeve maintains particularly well its cylindrical shape when compressed.
- the ring sections and the longitudinal webs are of rectangular cross section, the ring sections being preferably of comparatively great thickness and the longitudinal webs of comparatively small thickness.
- This configuration provides in a particularly reliable manner the required rigidity of the ring sections and yieldability of the longitudinal webs.
- the outer edges and the inner edges of the ring sections may be in the form of arcs of a circle, and are so formed that the ring sections constitute, prior to compression, an exactly circular inner surface, and, after compression, an exactly circular outer surface, of the sleeve shell. This is of advantage for winding up and unreeling of yarns and threads, and for their treatment on the sleeve.
- the ends may be provided with end rings to which the adjacent longitudinal webs are connected.
- end rings are in some cases of advantage in the axial compression of the sleeve and in winding or unreeling of yarns and threads on and from the sleeve.
- the ring sections, the longitudinal webs, and, where provided, the end rings are integral. This integral construction is particularly suitable for manufacturing the sleeve from plastics material.

- the sleeve may likewise be reduced from the state of FIGS. 1 and 2 to that of FIGS. 3 and 4 by radial compression.

Thus, the longitudinal webs 11 and 12 yield circumferentially also under radial compression, reducing the gaps between the ring sections 10 in the transverse and longitudinal directions, as shown in FIGS. 3 and 4. Thus also with radial compression of the sleeve, reduction of diameter is accompanied by reduction of axial length.

Furthermore, during compression of the sleeve there occurs deformation of the longitudinal webs 11a, 12a connected to the end rings 13, 14, both in the circumferential direction and towards the interior of the sleeve. In order to facilitate this deformation, the longitudinal webs 11a, 12a may be of tapering or otherwise weakened construction.

1 TEXTILE-TREATING SLEEVE BACKGROUND OF THE INVENTION The invention relates to a textile-treating sleeve, preferably of thermoplastic material, having a cylindrical or conical shell for the heat and/or wet treatment of yarns or threads. For such treatment, the yarns or threads are usually wound on sleeves and are subjected to the heat and/or wet treatment in this state. The heat treatment may be a shrinking process, and the wet treatment a dyeing process.
For many applications it is desirable that the sleeves undergo, simultaneously with their axial compression, also a reduction in their diameter, and vice versa, when they are radially compressed, a simultaneous reduction in the axial direction.
One of these applications is the treatment of texturated yarns, such as, e.g. the curled yarns sold under the trade name Helanca. For this treatment, the yarns are wound on the sleeves in a more of less stretched, tensioned state. When the sleeves are then axially compressed together with the yarn, the yarn tends to expand radially outwardly as well as radially inwardly. If no simultaneous reduction of the diameter of the sleeves occurs together with the axial compression thereof, the inner layers of the yarn tend to be more strongly compressed than its middle and outer layers, resulting in different results of the treatment within the-wound yarn, such as nonuniform dyeing and changes in the curl, which are undesirable.
Textile-treating sleeves, preferably of thermoplastic material, have already been proposed for these applications, in which an axial compression is accompanied by a positive reduction of the diameter-and, vice versa, a radial compression by a reduction in the axial direction.
One such sleeve comprises a shell having, in uniform distribution, elements which yield in both diagonal directions elastically and/or plastically, and rigid diagonal webs connecting these yielding elements.
Another proposed sleeve is characterized in that the shell has peripherally extending, spaced apart, axially elastically and/or plastically yielding rings and rigid longitudinal webs connecting the rings and arranged in spaced apart relationship, wherein axially consecutive longitudinal webs are laterally offset relative to each other.
The invention has the object of providing a textile-treating sleeve which is characterized by particularly good operation, and that especially insofar as it offers'a very good support for the yarns or threads to be wound thereon, and as it maintains to a far extent its cylindrical shape without distortion or twisting in its compression.
SUMMARY OF THE INVENTION This object is realized by a textile-treating sleeve of the kind hereinbefore mentioned, wherein the shell of the sleeve comprises consecutive rows of rigid ring sections extending cirlongitudinal webs elastically and plastically yieldable in circumferential direction.
With this configuration of the sleeve the longitudinal webs yield in the circumferential direction both under radial and under axial compression, and that mainly at the points at which they are connected to the ring sections, at which these points act like pivot joints. This causes, on the one hand, a reduction of the spacing between axially consecutive ring sections, as well as, on the other hand, a reduction of the spacing between transversely adjacent ring sections. Thus, when the sleeve is axially compressed, there occurs simultaneously a reduction of its diameter and, vice versa, when it is radially compressed, a shortening of its axial length.
According to the material of which the sleeve is made, the application of suitable pressures and temperatures will cause an elastic and/or plastic deformation of its yielding longitudinal webs. If, as is preferably done, the sleeve is made of thermoplastic material, for example polypropylene, its longitudinal webs will yield elastically at room temperature, and elastically as well as plastically at higher temperatures.
Owing to the presence and arrangement of the longitudinal webs the sleeve offers a very good support for yarns and threads to be wound thereon. Furthermore, the type and arrangement of the ring sections and longitudinal webs ensures that the sleeve maintains under compression to a far extent its cylindrical shape, without bending or twisting.
According to a feature of the invention the ring sections and the longitudinal webs are equidistantly spaced from one another and the ring sections of axially consecutive rows of rings are offset relative to each other by half their axial spacing. This arrangement results in uniform distribution of the ring sections and longitudinal webs over the shell of the sleeve, with beneficial effects on its operation.
In the sleeve of the invention thelongitudinal webs may be inclined relative to the axial direction, and the inclination of the longitudinal webs connected on one end portion of each ring section is opposite to that of the longitudinal webs connected on the other end portion of said ring section. This inclined arrangement of the longitudinal webs supports the formation of articulated joints at the connecting points between the longitudinal webs and the ring sections and facilitates yielding of the longitudinal .webs under axial or radial compression of the sleeve.
According to yet another feature of the invention, the direction of inclination of axially consecutive longitudinal webs changes alternately, and two axially consecutive longitudinal webs form an obtuse angle, pointing in the direction of the end of the ring section to which they are connected. This configuration provides particularly favourable conditions with regard to the yielding properties and stability of shape of the sleeve.
Furthermore, according to the invention, the longitudinal webs have, at their connecting points with the ring sections, a configuration which provides bending and buckling points. This construction provides for yielding of the longitudinal webs by bending and buckling at these points, and further im proves the yielding properties.
According to one embodiment of the invention, the end portions of the ring sections are connected by a single web each with the ends of the ring sections of axially adjacent rows of ring sections, and wherein the webs connecting adjacent ends of ring sections of axially consecutive rows of ring sections extend continuously from one end of the sleeve to the other.
In another embodiment of the invention, the ring sections of axially adjacent rows of ring sections overlap in the circumferential direction, and the overlapping parts of the ring sections are each connected by at least two spaced, parallel longitudinal webs. In this embodiment, when the sleeve is compressed, the ring sections are maintained parallel by the longitudinal webs. This isdue to the fact that the two or more spaced, parallel longitudinal webs form, with the parts of the ring sections to which they are connected, parallelograms and undergo a parallelogram displacement when the sleeve is compressed. In consequence, the sleeve maintains particularly well its cylindrical shape when compressed.
According to another feature of the invention, the ring sections and the longitudinal webs are of rectangular cross section, the ring sections being preferably of comparatively great thickness and the longitudinal webs of comparatively small thickness. This configuration provides in a particularly reliable manner the required rigidity of the ring sections and yieldability of the longitudinal webs.
Furthermore, in the sleeve according to the invention, the outer edges and the inner edges of the ring sections may be in the form of arcs of a circle, and are so formed that the ring sections constitute, prior to compression, an exactly circular inner surface, and, after compression, an exactly circular outer surface, of the sleeve shell. This is of advantage for winding up and unreeling of yarns and threads, and for their treatment on the sleeve.
Moreover, in the sleeve of the invention, the ends may be provided with end rings to which the adjacent longitudinal webs are connected. These end rings are in some cases of advantage in the axial compression of the sleeve and in winding or unreeling of yarns and threads on and from the sleeve.
Finally, according to yet another feature of the invention, the ring sections, the longitudinal webs, and, where provided, the end rings, are integral. This integral construction is particularly suitable for manufacturing the sleeve from plastics material.
For facilitating winding of threads and yarns to be treated on the sleeve, for improving the support of the threads and yarns on the sleeve, and for simplifying the unreeling of the threads and yarns from the sleeve, the sleeve may be provided with other parts in addition to the ring sections, longitudinal webs and end rings. Such other parts may be provided, for ex- BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is a side elevation of a first embodiment of the sleeve according to the invention, in the normal state;

DESCRIPTION OF PREFERRED EMBODIMENTS The sleeve shown in FIGS. 1 to 4 is made of thermoplastic synthetic resin. Its shell has rigid ring sections 10 and yieldable longitudinal webs ll, 12. The ends of the shell have end rings 13, 14. The ring sections 10, the longitudinal webs ll, 12 and the end rings 13, 14 are integral.
The ring sections 10 extend circumferentially of the shell. Their length is about one-twelfth the circumference, and they are arranged in circumferentially and axially consecutive rows, as shown. Therein they are equidistantly spaced in the axial and transverse directions of the sleeve. The ring sections 10 of adjacent rows of ring sections are offset relative to each other, the offset of ring sections 10 of axially consecutive rows being halftheir axial spacing.
The ring sections 10 are of rectangular cross section, wherein their short sides are located on the inner and outer surfaces of the shell, while their long sides extend substantially radially. However, instead of rectangular cross section, the ring sections 10 may be of conical cross section.
The end portions 15, 16 of the ring sections 10 are each connected by a longitudinal web 11, 12 with the end portions 16, I5 of each adjacent ring section 10. The longitudinal webs ll, 12 or 12, 11, which connect opposed end portions 15, 16 of the axially consecutive rows of ring sections 10, extend continuously from one end of the sleeve to the other. In addition, the longitudinal webs ll, 12 are inclined with regard to the longitudinal direction in such a manner that the inclination of the longitudinal webs ll, 12 or l2, 11 at one end 15 ofa ring section 10 is opposite to that of the other longitudinal webs l1, 12 or 12, 11 at the other end 16 of this ring section 10. Apart from that, the arrangement of the longitudinal webs l1, 12 is such that the direction of inclination of axially consecutive longitudinal webs l1, 12 or 12, 11 changes alternately, and any two consecutive webs ll, 12 or 12, 11 form an obtuse angle pointing in the direction ofthe end of the ring section 10 to which they are connected.
The longitudinal webs 11, 12 are also of rectangular cross section with the short sides on the inner and outer surfaces of the shell, and the long sides extending radially. As with the ring sections 10, the longitudinal webs ll, 12 may however be of conical cross section.
The longitudinal webs 11a, 12a at the ends of the sleeve are joined to the end rings 13, 14. These end rings l3, 14 are also of rectangular cross section but may also be of different crosssectional shape.
Although this is not shown in the drawings the thickness of the longitudinal webs 11, 12 can be reduced at their connections with the ring sections 10 in order to provide there bending and buckling points.
When the sleeve is axially compressed from the state of FIGS. 1 and 2 to the state of FIGS. 3 and 4, the longitudinal webs 11, 12 are exposed to a corresponding pressure and yield under this pressure in the direction of the circumference. In consequence the distance between adjacent, opposed facing ends 15, 16 of circumferentially consecutive ring sections 10 is reduced until they almost touch. This also produces a corresponding shortening of the gap between axially consecutive ring sections 10. In consequence, the axial compression of the sleeve will result in a positive shortening of the sleeve in the axial direction, combined with a positive reduction of its diameter, as shown in FIGS. 3 and 4.
However, the sleeve may likewise be reduced from the state of FIGS. 1 and 2 to that of FIGS. 3 and 4 by radial compression. If the sleeve is radially compressed,the same pressure as in axial compression of the sleeve is exerted through the ring sections 10 on the longitudinal webs 11 and 12. Thus, the longitudinal webs 11 and 12 yield circumferentially also under radial compression, reducing the gaps between the ring sections 10 in the transverse and longitudinal directions, as shown in FIGS. 3 and 4. Thus also with radial compression of the sleeve, reduction of diameter is accompanied by reduction of axial length.
Both axial and radial compression of the sleeve results in the deformation of the longitudinal webs 11, 12, shown in the FIG. 3, while the ring sections 10 maintain their shape. In consequence of this deformation, the angles formed'by the longitudinal webs 11, 12 or 12, 11 at the end portions 15, 16 or the ring sections 10 become more acute. Furthermore, during compression of the sleeve there occurs deformation of the longitudinal webs 11a, 12a connected to the end rings 13, 14, both in the circumferential direction and towards the interior of the sleeve. In order to facilitate this deformation, the longitudinal webs 11a, 12a may be of tapering or otherwise weakened construction.
The sleeve shown in FIGS. 5 to 8 of the drawing is similar in construction and operation to the sleeve describedabove.
This sleeve is also made of thermoplastic synthetic resin. Its shell consists of rigid ring sections.20 and yieldable longitudinal webs 21,22, the ring sections 20 and the longitudinal webs 21,22 being integral.
The ring sections 20 extend circumferentially of the shell, have a length of about one-fifth the circumference, and are arranged in circumferentially and axially consecutive rows, as shown. Therein they are equidistantly spaced in the axial and transverse directions of the sleeve. The ring sections 20 of adjacent rows are offset relative to each other, the offset of the ring sections 20 of axially consecutive rows being half their axial spacing. In addition, the ring sections 20 of adjacent rows overlap in the circumferential direction.
The outer and inner edges of the ring sections 20form arcs of a circle and are so formed that they form, prior to compression of the sleeve, an exactly cylindrical inner surface 23, and, after compression, an exactly cylindrical outer surface 24.
The ring sections'20 are of rectangular cross section and are comparatively thick to produce the required rigidity. The short sides of the ring sections 20 are on the inner and outer surfaces of the sleeve shell, while the long sides extend substantially radially.
The overlapping parts of the ring sections 20 are connected by two circumferentially yielding longitudinal webs 21 or 22, respectively, which are spaced apart and parallel. The longitudinal webs 21 and 22 are inclined relative to the longitudinal direction. The inclination of the longitudinal webs 21, 22 connected to one end 25 of each ring section 20 is opposite to that of the longitudinal webs 21 and 22 connected to the other end 26 of the same ring section 20. Also the longitudinal webs 21, 22 are so arranged that the direction of inclination of two consecutive webs 21, 22 or 22, 21 changes alternately, and any two axially consecutive longitudinal webs 21, 22 or 22, 21 form an obtuse angle, pointing in the direction of the end 25, 26 of the ring section 20 to which they are connected.
The longitudinal webs 21, 22 are also of rectangular cross section and are comparatively thin to produce the required yielding properties. Their short sides are on the inner and outer surfaces of the sleeve shell, and their long sides extend substantially radially.
Although this is not shown in the drawings likewise in this sleeve the thickness of the longitudinal webs 21, 22 can be reduced at their connections with the ring sections 20 to provide at these connections bending and buckling points.
When the sleeve is axially compressed from the state of 'FIGS. 5 and 6 to that of FIGS. 7 and 8, a corresponding pressure is exerted on the longitudinal webs 21, 22 causing them to yield in the direction of the circumference. In consequence, the distances between circumferentially facing ends 25, 26 of the ring sections 20 is reduced until they almost touch. In addition, there occurs also a corresponding reduction of the axial distance between axially consecutive ring sections 20. In consequence, the axial compression of the sleeve will produce, together with the axial shortening, necessarily also a reduction of its diameter, as shown in FIGS. 7 and 8.
However, the sleeve may also be reduced from the state of FIGS. 5 and 6 to that of FIGS. 7 and 8 by means of radial compression. If the sleeve is radially compressed, the longitudinal webs 21, 22 are affected through the ring sections 20 with the same pressure as in the case of axial compression. The longitudinal webs 21, 22 yield therefore also under radial compression of the sleeve in the direction of the circumference, causing the distance between the ring sections to be reduced in the transverse and axial'directions, as shown in FIGS. 7 and 8. Consequently radial compression of the sleeve also results in a shortening of its axial length together with the reduction of its diameter.
Both axial compression of the sleeve and radial compression result in a deformation of the longitudinal webs 21, 22 as shown in FIG. 7, while the ring sections '20 maintain their shape. In addition, the compression of the sleeve results therein that the ring sections 20 and the longitudinal webs 21, 22 are closely spaced and form an almost closed cylindrical shell.
