Description

Dec. 5, 1967 B. K. JOHNSON ET AL 3,356,313
YARN PACKAGE Filed OC'C. 5, 1966 Ailorneys United States Patent O 3,356,313 YARN PACKAGE Bryan Kingsley Johnson, Abergavenny, Thomas Henry Roberts Browning, Monmouth, and David Francis Gilbert Mansfield, Pontypool, England, assignors to Imperial Chemical Industries Limited', London, England, a corporation of GreatBritain Filed ct. 5, 1966, Ser. No. 584,414 Claims priority, application Great Britain, Oct. 15, 1965, 43,828/ 65 4 Claims. (Cl. 242-165) The invention concerns improvements in or relating to yarn packages.
Yarn packages are normally wound on bobbins, tubes, etc., by rotating a spindle on which the bobbin or tube is mounted and by traversing the yarn axially of the spindle in such a way as to build a package of the desired shape and size.
Winding may be performed with or without concomitant twisting. Winding with twisting is conveniently carried out on to a bobbin or tube, to form a tapered-end type of package, on a ring spindle apparatus; Winding without twisting is conveniently carried out on to a tube, to form a cheese type of package, on a side-winding apparatus.
It is often the practice in winding processes, as for instance that of winding after drawing yarns of synthetic polymeric material, to dispose of the initial lengths of yarn, lwhich may not have uniform properties owing to the starting-up of the process, as Waste. Disposal may be on to a waste tube below the bobbin or tube, or into a suction tube and waste collection device.
Also it is now common practice to wind a bunch, or to wind spaced helical turns, on the lower end of the bobbin or tube to act as a transfer tail.
As for the running, or free, end of yarn which is cut at the completion of winding, this may be left loose around the body of the package, or be secured by a clamp at the top of the bobbin or tube, or be trapped in the sealed end of a polythene wrapper for the package.
It has now been observed, however, that just as the initial lengths of yarn may not be fully processed owing to the starting-up of the apparatus, so the final lengths of yarn may not always be fully processed owing to the slowing-down of the apparatus. This may occur, for instance, in the drawing process above referred to, especially when it is carried out at the high speeds now possible; and even more so when some other process is combined with drawing, for example, a crimping process, or a heat treatment to relax the yarn.
lt is often essential that any defective slow-down yarn shall be readily separable from the main body of the yarn in the package, as it is not yalways possible to indulge in any yarn stripping activities.
The main object of this invention, therefore, is lto provide a yarn package of which the final lengths of yarn are wound clear of the main body of yarn in the package, so as to be readily separated therefrom.
According to the invention a yarn package comprises a body of yarn wound in a shaped build on a bobbin or tube, a transfer tail wound at one end of said bobbin or tube clear of the said body of yarn in the shaped build, and a waste receiving device, such as a sleeve or spool removably fitted at the opposite end of said bobbin or tube and clear of said body of yarn, on which waste receiving device are wound the final lengths of yarn comprised in the yarn package.
By means of the invention, there is provided a yarn package from which the slow-down yarn can be readily 3,356,313 Patented Dec. 5, 1967 removed either before packing or before utilization by a yarn consumer.
Further, such a yarn package can be produced by a winding process which is simple in execution, in that at the completion of winding the main body of yarn in the shaped build the traverse is simply shifted outwardly from said body towards the end of the bobbin or tube to the location of the sleeve or spool, yand the winding apparatus slowed down and brought to a stop whilst the yarn is wound thereon.
If the slow-down yarn were to be wound either on to a waste sleeve beyond the bobbin or tube surface at that end on which the transfer tail is wound, or on to the surface of the main body of yarn itself, difficulties would be likely to be encountered.
In the rst instance, yarn would first be wound over the transfer tail (and over the lower taper of a taperedend package) which is technically undesirable in connection with the subsequent utilization of the package; and in the second instance, the slow-down yarn would first have to be stripped from the main body before utilization of the yarn from the package could be commenced.
-In -the case of the yarn package of the invention, the running end of yarn is kept clear of the transfer tail, and it is at the end of the package from which withdrawal commences.
A yarn package according to the invention is illustrated in the accompanying drawing which is an elevation view of the completed package.
In the drawing, a body of yarn in a shaped build 1 is carried on a cylindrical tube 3, the initial lengths of yarn comprising a transfer tail of spaced helical coils 5, the lowermost one of which is secured by a spot of gum 7.
A waste receiving device in the form of a removeable sleeve 9 is a detachable lit on tube 3 at the opposite end thereof from that on which the transfer tail 5 is wound. The final lengths of yarn 11 are Wound on said sleeve.
If the waste-receiving device takes the form of a sleeve, such can be made of plastics material, rubber, cardboard or metal; and it will be so shaped as to be a detachable fit to the end of the bobbin or tube. If the device takes the form of a spool, it may be attachable to the end of the bobbin or tube, or to the tip of the spindle; and, when to be used with a ring spindle Wind-up, it should be of a shape and size to keep it clear of the balloon The running end of yarn, once the waste-receiving device has been removed from the bobbin or tube and the end cut close thereto, is preferably secured in any convenient way to that end of the bobbin or tube, until required for use.
Yarn pack-ages according to the invention may be, for instance, of the draw-twist variety in which the yarn is drawn and then twisted and wound into a double taper build shape; or they may be of the cheese type, in which the yarn is wound, without twisting, into a cylindrical package with square ends.
The nature of yarn material is immaterial to the invention; but the invention has been found to be most useful for continuous filament-ary yarn of monoflarnents of synthetic polymeric material, as for instance, polyamide, polyester and polypropylene material, and especially for such continuous filamentary yarn when in a bulked or latently-bulked condition following from a crimping proc4 ess havin-g -been carried out thereon, or when in heatrelaxed state.
We claim:
1. A yarn package comprising a body of yarn wound in a shaped build on a bobbin or tube, a transfer tail wound 4at one end of said bobbin or tube clear of lche said -body of yarn in the shaped build, and wherein the nal lengths of yarn comprised in the yarn package are wound on a waste receiving device removeably tted at the opposite end of said bobbin or turbe lto the end on which the transfer tail is wound.
2. A yarn package `according to claim 1 wherein the waste receiving device is a detachable sleeve on lthe said bobbin or tube.
3. A yarn package according to claim 1 wherein the transfer tail consists of spaced helical turns.
4. A yarn package according to claim 1 wherein the package is a double taper draw-twist package.
