- the steaming chamber 2 is surrounded by an outer casing 14 of thermally insulating material.
- the steam supplied by the main duct 10 emerges through holes 15 provided in the duct and diffuses into the space between the upper wall 11 of the chamber 2 and the casing 14 of insulating material, heating the chamber 2 from its upper wall 11.

Description
- The present invention relates in general to the treatment of yarn and is particularly concerned with the formation of windings of yarn intended to be subjected to a treatment such as steaming.
- For this purpose, starting with the yarn wound tightly onto a reel or bobbin in a condition in which it cannot be treated, a generally looser winding is formed. The latter is deposited on a transporter, such as a conveyor belt, which carries it into the treatment chamber. The winding of yarn is prepared by winding the yarn to be treated onto a winding core extending in a fixed direction of winding.
- Devices are known in the art for forming windings of yarn, which include a winding core with an input end and an output end and with a rotary head for supplying the yarn which is able to wind the yarn into coils around the input end of the winding core. The winding advances on the core towards its output end due to entrainment by the transporter.
- More specifically, the present invention relates to a winding device having the features set forth with pre-characterising portion of Claim 1, which is known e.a. from DE-A 2 847 291 and DE-A 2 939 716. The object of the present invention is providing such a device, which ensures, in all operating conditions, the regularity of the winding of the yarn onto the core and its gradual advancement towards the output end of the core itself.
- According to the present invention, this object is achieved by virtue of a winding device having the further features set forth in Claim 1.
- The invention also relates to apparatus incorporating a winding device of the type specified above.
- The invention will now be described, purely by way of non-limiting example, with reference to the appended drawings, in which:
- Figure 1 shows schematically in longitudinal vertical section the structure of apparatus for the steaming of yarns, produced according to the invention,
- Figure 2 is a section taken on the line II-II of Figure 1
- Figure 3 is a section taken on the line III-III of Figure 1, on an enlarged scale,
- Figure 4 is a view taken on the arrow IV of Figure 3, and
- Figure 5 is a longitudinal vertical section substantially similar to Figure 1, which illustrates a possible variant of the apparatus according to the invention.
- In Figures 1 and 2, apparatus usable for subjecting a yarn F to steaming is generally indicated 1. The yarn F is unwound from a supply reel or bobbin B1 to be rewound onto a collecting reel or bobbin B2 after treatment.
- The steaming is carried out by exposing the yarn to the action of the steam which collects in the
treatment chamber 2 of the apparatus. - For this purpose, an elongate winding of generally loose coils of yarn is formed from the yarn F supplied from the bobbin Bi, by means of a
device 3 whose structure will be better explained below with reference to Figures 3 and 4, so as to enable good penetration of the steam into the yarn. - According to a widely known solution, the winding of yarn formed by the
device 3 is placed on a transporter device, for example aconveyor belt 4, which advances the winding from an inlet opening 5 to an outlet opening 6 provided in the walls of thechamber 2. - The upper pass of the
conveyor 4 which receives the yarn is supported by rollers or pulleys arranged in such a way as to give the pass a profile in which an initial ascending section (in the direction of advance of the yarn), a central approximately horizontal section, and a final descending section can be distinguished. - At the outlet from the
treatment chamber 2, which is generally prismatic in shape, the winding of yarn is passed over a ve ntilator device 7 operated by a suction element 8, in order to cool the yarn before it is rewound onto the collecting reel or bobbin 82. - As better seen in the section of Figure 2, the apparatus 1 may in fact include one or more transporter devices 4 (in the example illustrated, ten) each of which advances a winding of yarn formed by a device of the type indicated 3 in Figures 3 and 4 into the
chamber 2. - The heating in the
chamber 2 and the diffusion of the steam within the chamber is effected through a steam distribution duct 9 (connected to a source of steam, not illustrated in the drawings) including amain branch 10 and asecondary branch 12. Themain branch 10 extends near (and preferably over) the upper wall orhead 11 of thechamber 2, while thesecondary duct 12 conveys the steam towards a grid orcoil 13 which extends within thechamber 2 in its base region, which is completely open or at any rate provided with apertures, in a position below thetransporters 4. - The
steaming chamber 2 is surrounded by anouter casing 14 of thermally insulating material. The steam supplied by themain duct 10 emerges throughholes 15 provided in the duct and diffuses into the space between theupper wall 11 of thechamber 2 and thecasing 14 of insulating material, heating thechamber 2 from itsupper wall 11. Subsequently, the steam issuing from themain duct 10 is propagated downwardly inside thecasing 14 and enters thesteaming chamber 2 from the bottom. The vapour from theduct 10 thus penetrates thechamber 2 from its (open or at any rate apertured) base region where thecoil 13 is situated so as to be able to give up heat to the steam supplied to thechamber 2, to prevent the temperature of this steam falling below predetermined values. - Since the
chamber 2 is heated from itstop wall 11, using steam which is only subsequently introduced into thechamber 2 itself, theupper wall 11 is certain to remain at a temperature which is even a little higher than the temperature in thechamber 2. In this way, condensation of the steam on thewall 11 and consequent dripping of any condensate formed onto the yarn F which is being treated is completely avoided. - In Figure 3, a motor, for example an electric motor, is indicated 16 and is provided with a
shaft 17 which is traversed by alongitudinal cavity 18 at least in its portion extending within themotor 16 itself. Ascrew 19 including acore 20 and at least onethread 21 is mounted on the free end of theshaft 17, that is, the end opposite the body of themotor 16. - A rotary head, indicated 22, has a generally bell- shaped configuration with an apex part rigidly keyed to the
shaft 17 and acircular end edge 22a extending in a plane perpendicular to the axis of theshaft 17, in substantial alignment with the free end of theshaft 17. - The
bell 22 is traversed by acavity 23 which extends along one of the "generatrices" of the bell and is connected in the region of theangle 24 with thecavity 18 of theshaft 17. - At the opposite end, that is, at the free end of the
head 22, thecavity 23 has an opening 25 facing thescrew 19. - The
cavity 18 and thecavity 23 together define a duct for feeding a yarn F towards theopening 25. The yarn F is introduced, usually by pneumatic means, into thecavity 18 from the rear of themotor 16, that is, the end opposite thebell 22. The yarn passes into thecavity 23 and from the latter towards the opening 25, advancing continuously through thecavities bell 22 caused by the operation of themotor 16. - Two lining sleeves of ceramic material are indicated 26 and have the function of preventing the yarn from wearing grooves in the material (usually metal) of the
shaft 17 and thebell 22, in the regions of theangle 24 and theopening 25, as it advances rapidly (600-1000 m/min) within thecavities - Since the
head 22 must be rotated at high speed in order to ensure the speed of advance indicated, afurther cavity 23a which is completely identical to and symmetrical with the cavity 23 (baricentrically symmetrical) is provided in thehead 22. Thus, thehead 22 is prevented from becoming unbalanced and oscillating or vibrating during rotation. - A fork element is generally indicated 27 and is arranged to act as a core for the winding of the yarn F.
- The
fork element 27 is constituted by abase part 28 which is generally sleeve-shaped, and two arms orprongs 29 which extend from thesleeve 28. - The
sleeve 28 is fitted onto theshaft 17 in an intermediate position between the base part of thebell head 22 and the end on which thescrew 19 is mounted, with the interposition ofbearings 28a which allow thesleeve 28 and thefork 27 to rotate freely together relative to theshaft 17, that is, not to be forced to rotate when theshaft 17 rotates due to the operation of themotor 16. - As can be seen in Figure 3, in the final assembled arrangement, the two arms or prongs 29 of the
fork 27 extend from thesleeve 28 away from thebell head 22. - Each
arm 29 has an upstream orinput end 30a situated in correspondence with the free end of thebell 22a and thescrew 19, and a respective free oroutput end 30b. - In general, the two
arms 29 are located in symmetrical positions relative to the axis of theshaft 17, which coincides with the axis of symmetry and rotation of thescrew 19. - The yarn which emerges from the
aperture 21 is wound onto the twoarms 29 of thecore 27, as better illustrated in the sectional view of Figure 4. - The
bell head 22 is in fact rotated by theshaft 17 of the motor, while the windingcore 27 is kept in a fixed position (by means which will be better explained below). - Consequently, the yarn is wound onto the
core 27 to form coils of which two opposite portions Si, S2 are discernible and which extend freely between the twoarms 29. The free portions of each coil S1, S2 also rest on thecore 20 of thescrew 19 and are thus exposed to the entrainment action exerted by thethread 21, the sense of which is selected so as to cause the forced advance of the coils which are gradually formed on thecore 27 from theinput end 30a towards the free oroutput end 30b of the arms. - In this way, a winding of yarn F is formed which may be deposited on the upper pass of the
conveyor 4 to be advanced subsequently into thesteaming chamber 2. - The input end of the
conveyor 4, constituted by a roller or pulley 31 for driving the conveyor belt, is brought into contact with the windingcore 27 immediately downstream of the region in which thescrew 19 acts as a positive driving element. - The wheel or pulley 31 is preferably mounted on a support apparatus 32 (Figure 1) which is kept resiliently (or at any rate so that its position can be varied) in contact with the lower face of the winding
core 27. - The fact that the
core 27 is, so to speak, resting on the wheel or roller 31 ensures that the core remains securely in a fixed position and is not thus rotated by theshaft 17 due to friction. At the same time, the fact that the position of the wheel or roller 31 is adjustable (for example, with a resilient mounting schematically illustrated here by a spring 33) enables this position to be adapted precisely to the variations in diameter (count) of the yarn which is being wound. - In the embodiment illustrated in the drawings, the
arms 29 of the winding core 7 converge slightly. In this way, it is possible to allow for any shrinkage of the yarn which may occur immediately after the winding has been formed. - In this connection, a solution can also be envisaged in which the
conveyor belt 4 is eliminated, while thearms 29 of thecore 27 and thescrew 19 are lengthened so as to act as elements for guiding and transporting the winding of yarn which advances into a chamber for steaming or treatment generally. In this case, the diametral dimensions and the relative positions (convergence) of thearms 29 of thewinding core 27 could be selected so as to allow exactly for the shrinkage of the yarn due to the treatment. For the purpose of this possible configuration of use, the use is envisaged (and therefore fully encompassed by the scope of the present invention) ofwinding cores 27 in which the positions and/or the inclinations of thearms 29 relative to thesleeve 28 are selectively variable and adjustable (by means of screws). - The use may also be envisaged of a
screw 19 having acore 20 and/or threading 21 generally tapered away from the input end 30 of the windingcore 27. Moreover, as regards the general configuration of this core, solutions may be used which are of different types from those illustrated in the drawings but which still provide for at least one free portion of the coils of yarn to be subjected to the driving action of thescrew 19. - As far as the general configuration of the apparatus 1 is concerned, the Applicant has been able to observe that with some types of yarn, such as so- called "single filament", that is non-multiple, yarns, the solution illustrated in Figure 1 may sometimes give rise to phenomena of curling and knot formation. These phenomena inhibit the subsequent operation of rewinding the steamed yarn onto the collecting bobbin.
- These problems are, however, completely eliminated if, according to the solution illustrated in Figure 5, the winding of yarn to be steamed is formed inside the steaming chamber. This may be achieved by inserting the device or winding
head 3 within theinlet opening 5 of thesteaming chamber 2, so that the winding of yarn F to be steamed is formed inside thechamber 2, not outside as in the solutions according to Figure 1. - At the outlet of the
chamber 2, the winding of yarn is passed over the ventilation device 7 operated by the suction element 8, in order to cool the yarn before it is rewound onto the collection reel or bobbin B2. - According to the solution already described in detail with reference to Figure 1, the heating of the
chamber 2 and the diffusion of the steam within the chamber is effected through the steam distribution duct 9 with itsmain branch 10 which extends near the upper wall or head of thechamber 2, and itssecondary duct 12 which conveys the steam towards the grating orcoil 13 extending in the bottom of the steaming chamber. - According to an advantageous improvement, a shaped
cover 60 is associated with the outlet opening 6 of thechamber 2 and extends like a roof above the outlet opening 6 towards the outside of thesteaming chamber 2. The function of thecover 60 is to protect against the escape of steam from the steaming chamber. - The return pass of the
conveyor belt 4 extends beneath thesteaming chamber 2 and re-enters thesteaming chamber 2 through anopening 50 provided in the base wall of the chamber in the region immediately below theinlet opening 5 in which the windingdevice 3 is inserted. - As in the case of Figure 1, the
device 3 is substantially constituted by a windingcore 27 including two converging arms on which the yarn F is wound in coils due to the rotation of thehead 22 driven by thehollow shaft 17 through which the yarn F, unwound from the reel or bobbin Bi, enters thedevice 3. The winding of yarn formed by the rotation of thehead 22 is advanced along the arms of the windingcore 27 by thescrew 19 which is also driven by theshaft 17. - In the solution illustrated in Figure 5, the
shaft 17 is driven by amotor 16 through a belt orchain transmission 16a. Themotor 16 may thus be located in a position out of alignment with theshaft 17, so as to permit the free passage of the yarn towards the winding device. - A further motor (geared motor) 40 arranged below the device 1 drives the
conveyor 4 through a drivingpulley 41.
