Grenoble, France, assignors, by mesne. assignments, to Textile and Chemical Research Company Limited, St. Peter Port, Guernsey, Channel Islands, a corporation of Great Britain Application January 19, 1950, Serial No. 139,494 In the Netherlands January 26, 1949 1 Claim.
This invention relates to yarn packages and more particularly to cop type bobbins and to packages wound thereon.
An object of the invention is to provide a yarn package which is readily wound on standard ring and traveler yarn twisters and is characterized by a relatively large weight of yarn with respect to the bobbin.
Another object is to produce a package in which the tendency of a plurality of turns to come off in a bunch during unwinding is practically eliminated.
Another object is to provide a bobbin of novel and improved form.
Other objects and advantages will be apparent as the nature of the invention is more fully disclosed.
The cops used for winding yarn on ring-andtraveler twisting frames generally consist fundamentally of a base in the form of a truncated cone surmounted by a cylindrical barrel. The winding is made in conical layers of a constant width corresponding to the altitude of the truncated cone constituting the conical base, and with progressive displacement from the starting point towards the top of the support, so as to produce the common bottle spool.
When a winding of this type is unwound overhead onto cylindrical or conical supports, it is sometimes found that several turns will come off in a bunch because of the conical form of the surface from which the unwinding takes place. Furthermore, the relative weight of wound yarn to the weight of the cop is inefficiently low, for the cops are generally of solid wood. However, even if they are made of cardboard or metal tubing, although the weight of wound yarn is increased relative to the weight of the support, the quantity of wound yarn remains small relative to the volume occupied.
One common way of making bottle-type spools containing more wound yarn is by the use of a support consisting of a cylindrical barrel with a wide flange at the bottom and a small flange at the top. In order to obtain a oylindro-conical winding on this support, a special reciprocating motion is used which travels over the entire height of the barrel with acceleration of the said Also,
the conical shape of the upper part of the winding reduces the total weight of wound yarn. Finally, the acceleration of the reciprocating movement in the upper portion of the paths presents mechanical problems, particularly when the linear speed of winding is high (reduced twist) and when the normal frequency of the reciprocating motion is already high in the unaccelerated portion. It is further requisite, in order to avoid excess thickness of winding at the flanges, to provide a supplementary reciprocating motion of reduced amplitude, which renders the mechanism still more complicated. The packages obtained, however, have advantages over the usual bottle-type ones, and the risk of the giving way of packs of turns when unwinding overhead is reduced.
The present invention provides a symmetrical cylindro-bi-conical support with elongated cones, but without flanges. The cylindrical barrel covers one-third to one-half of the total height. The supports may be used on. existing ring-and-traveler machines, without introducing supplementary motions.
In accordance with the present invention the amplitude of the reciprocating motion of the yarn guide is increased to from to or more above the height of the lower (or upper) cone (since the two are identical), but with a reduced progressive shifting so that successive layers are displaced only slightly in an axial direction.
In this case, considerably more yarn can be wound than on the usual cops. The surface is approximately barrel shaped and slightly bulging. It is possible to wind up to 1000 grams of yarn, in the case of rayon, without diiiiculty, and unwinding becomes extremely easy. The increased amplitude of the reciprocating motion is readily arranged on existing twisters. No acceleration of the reciprocating motion is required.
In the drawing the single figure is a diagrammatic representation of a package illustrating one embodiment of the invention with the thickness of the layers greatly exaggerated.
Referring to the drawing, the bobbin used consists of a conical base I whose height is a fourth of the total height, a cylindrical barrel 2, and an upper conical portion 3 symmetrical with the base I. The spooling begins at the base as usual, but with an amplitude double or triple the height of the cone as shown by the layer Hi. The shifting of successive layers progressively upwards takes place as usual during winding. As the cal end portions together extending over from one-half to two-thirds of the total bobbin height, and a winding thereon comprising layers of yarn,
each layer aving an amplitude at least 50% greater thanlthat of a frusto conical end pors'being progressively ofiset from one end to te other end of the bobbin and having a uniform low pitch with successive turns in contact from end to end, said winding having a barrel-shaped. outer surface with tapered end portion.
