No. 695,256
Claims priority, application France Nov. 14, 1956 4 Claims. (Cl. 57-106) The invention relates to means for permitting very high speed unreeling of spinning or twisting spools which are wound in more or less slanting layers.
Hitherto high speed unreeling has been possible only oif spinning spools for parallel or American style winding which presupposes various more difiicult spinning and winding methods. The invention is intended to overcome this restriction and in particular to permit, irrespective of the count of yarn, the use of any spinning or winding cops which are cross-wound in slanting layers at variable angles and which are employed much more Widely in Europe, at unreeling rates which may exceed 1000 metres a minute. The device according to the invention consists essentially of a special unreeling device to prevent collaps ing of turns of different diameters. Anti-ballooning devices in the shape of a ring or a cylinder concentrically surrounding the spool are known. From the United States patent specification of Griggs, In, N9, 2,170,194 of August 22, 1939, is also known an anti-ballooning device composed of a hollow cone or funnelfitted above the spool concentrically with it and along the internal wall of which the yarn slides, thus preventing it from collapsing and forming a second balloon; but, owing to the sliding friction involved, the tension of the thread is greatly increased and produces on the receiving bobbin an extremely dense package of thread, even so dense that the' liquid chemical agents used in subsequent treatment, e.g. dyeing or bleaching, fail to penetrate the package, while the unreeling rate cannot much exceed 300 to. per minute. Owing to this considerable friction of the thread the known devices thus do not permit of unreeling at very high speed. In order to avoid the drawbacks of a large contact surface between the thread and the unreeling device, and in order to break the balloon instead of regularising or preventing its formation, the unreeling device according to the invention is composed of a fence of such general shape that in the immediate vicinity of the bobbin it presents a surface following more or less closely the form of the cop reduced to at most two diametrically opposed lines, this fence being fitted so as to be adjustable and not to interfere with the withdrawal of exhausted bobbins while permitting of easy piecing the broken threads as well as unreeling indiscriminately Z or S torsions. The distance between the fence and the surface of the thread package on the bobbin is preferably between 1 mm. and mm.
The unreeling device according to the invention has the advantage over known systems of reducing the thread tension between the point where the thread strikes the unreeling device and the receiving bobbin, thus permitting of cross-winding the bobbins with less density and thereby facilitating penetration of the chemical agents during operations, e.g. bleaching and dyeing. The device furthermore favours elimination, by a picking effect, of any slubs or fluff still adhering to the thread, this being a further advantage over the known unreeling devices in which the thread slides over a ring-shaped, cylindrical or conical surface serving as an anti-ballooning device.
The attached drawings show diagrammatically several examples of unreeling devices.
FIG. 1 is a partial vertical section showing one possible application of the invention.
FIG. 2 is a similar view of a first, more diagrammatic variation.
FIG. 3 is a section along III--III of FIG. 2.
FIG. 4 is a view similar to FIG. 2, of another variation.
FIG. 5 is a section along V-V of FIG. 4.
FIG. 6 is a view similar to FIG. 2, of a third variafrom.
FIG. 7 is a horizontal section, similar to FIG. 3, of another variation.
As shown in FIG. 1, a bobbin 1 carrying thread 2 is mounted upon a dead spindle 3 carried by a rail 4. Thread 2 is unreeled by the action of a system not included in the invention and well known by itself. The
thread is wound on a spool not shown, in the direction of arrow 7, after passing around a direction-changing rod 8. The rod 8 as well as the thread-guide 9 through which the thread passes before reaching roller 5, is supported upon the machine frame (not shown) by a support 10. The machine frame also carries the rail 4 in a known manner. In order to prevent the turns of thread 2 from collapsing during the high speed unreeling, the invention provides for an anti-ballooning device consisting in the example shown, of a fence comprising a wire 11. This wire may be of metal, preferably steel, or of plastic, suitably sheathed, if desired, and curved at 12 so as to follow more or less the outline of the cop during unreeling. It is attached in any suitable manner, eg by nuts 13 screwed on threaded ends of the wire, to a vertical plate 1%, through holes suitably drilled in the plate. The plate 14 forms one of the sides of the spindle frame 3. It may for exampie be bolted at 15 to rails 16 attached in turn to the machine frame (not shown). In FIG. 1 it is assumed for greater clarity, that plate 14 is the rear plate of the cop casing, that is to say that the operator of the machine would be to the left of the figure. In practice, however, the fence constituting the unreeling device is preferably attached to one of the lateral partition plates of the casing as this facilitates mounting of the device and does not interfere with the operator when withdrawing empty cops or piecing broken thread.
It will be seen that when thread 2 begins to collapse during unreeling it comes up against fence '11, for example at 12, and is restrained by the latter. Although the cop is wound on in slanting layers at variable angles, thread breakages are thus greatly reduced and at an equal unreeling rate (1000 m. per minute) do not exceed the breakages of cops wound on in parallel.
In FIGS. 2 to 7 the various elements are shown in a much more diagrammatic form but the same parts are generally designated by the same reference numbers.
In these figures it is assumed that the operator is standing in front of her machine in front of the plane of FIGS. 2, 4 and 6, and perpendicularly to the plane of and at the foot of it in FIGS. 3, 5 and 7.
In FIG. 2, the thread 2 is unreeled from the cop 1 and passes through thread guide 9. In this case the unreeling device consists of a metal or plastic fenceplate 17 attached by bolts 18 to a vertical partition 19. This fence-plate has a free edge 20 cut approximately to suit the shape of the bobbin. As shown in FIG. 3, the plate 17 has a horizontal flange or at least fixation lugs and is attached to partition 19 by the short limb 21 of such flange or lugs.
In FIG. 4 is shown an unreeling device made of two fence-blades diametrically opposed with respect to cop 1. The larger blade 22 having a horizontal flange (FIG. 5) or fitted with lugs like blade 17, is fastened by bolts 18 to a partition 19. At 23 it is rounded oil at the lower end to fit the external contour of the cop; and a 24, at the top, it is straight. The second part or fence-blade 25 of the unreeling device shown in FIGS.
4 and 5 is essentially shaped like a right-angled triangle (preferably with the acute angles chamfered) and has flanges or lugs for bolting it, at 18, to the second partition 19 which separates the spindle under consideration from the next, and to part 26 which is or carries thread guide 9. In FIG. 5 the fence blade 22 has a sharp edge 24, while blade 25 has preferably a rounded off edge 27. In a variation not shown, a blade like 17 of FIG. 2 may have a rounded off edge like edge 27. Likewise, in another variation, edges 24 and 27 might both be rounded off. Lastly, in another variation, at least one of the fence-blades 22 and 25 could be adjustably mounted, e.g. by replacing the bolt holes in the partitions 18 by slots. Obviously, in that case, the attachment of fence blade 25 to one of the parts 19 and 26 would have to be eliminated unless fence-blade 25 has a slide enabling it to move simultaneously in a vertical direction and radially with respect to the cop. In yet another variation there could be two fence-blades, like 17 or 22, placed diametrically with respect to the cop and one of which at least would have a rounded edge. In FIG. 6 the fence blade 28 has a cross section like blade 22 but of slightly lower height, and part 29 with thread guide 9 comprises two extensions 30 which have a sloping surface 31 and complete the anti-ballooning device.
In FIG. 7 the unreeling device consists of a fenceblade 35 V-shaped in horizontal cross section, the apex of the V 36 being next to the cop I. The blade 35 is moreover bolted at 18 by means of flanges or lugs to one of the partitions 19. The edge 36 may be sharp or rounded. The shape of the unreeling device in FIG. 7 may, of course, be in vertical cross section of any type whatever, for example like that of fence- blades 17, 22 or 28 so as to follow as closely as possible the form of the cop during unreeling.
In every case the surface of the unreeling device with which the thread is likely to come into contact may be given a camber, cutting edge, polish or corrugation according to the nature of the thread, while the distance between. this guide surface. and the external surface of the cop may also be adjustable in accordance With the unreeling rate and maximum cop diameter. The blade or wire composing the fence of the unreeling device may be flexible or rigid. Moreover, the number of fences of the type of FIGS. 1 and 2' may be doubled with the two guide surfaces diametrically opposed with respect to the cop. Lastly and irrespective of its shape, the unreeling device can be fitted 'adjustably by means of any known device, e.g. slides or slots for the fixing devices.
The greatest advantage of the unreeling device according to the invention is its adaptability to any type of high speed reeling machine. Tests have shown that the unreeling rate can be pushed up to nearly 1200 yards/minute, the results at rates of 1000 to 1100 yards being very satisfactory.
It should be clearly understood that the possible applications described and illustrated are given merely as examples and are subject to numerous modifications in detail Without going beyond the spirit of the invention.
