8 Claims.
This invention relates to a novel means for winding and twisting yarn, and relates more particularly to a means for forming large size packages of yarn.
The formation of large-sized packages of yarn, and more particularly the formation of such packages on single-end bobbins, has presented numerous difliculties. In forming such packages the yarn must be wound under sufficient tension to forma package which is not only firm but which will retain its form when handled. Where there is insuflicient or uneven tension in the yarns the resulting package will be soft and tend to come apart at the end, or else subsequent twisting operations will give a yarn lacking in uniformity. Furthermore, the tension under which the winding takes place must be such that the turns of each layer are wound closely and firmly without any tendency to slip and jam between the threads of the layer beneath. Threads which jam in this manner tend to break in subsequent unwinding operations which causes delay and considerable wastage of thread. It is, therefore,
desirable that a winding device be obtained to overcome these dimculties.
An object of our invention is to provide a takeup device for winding and twisting 'yarn into large firm packages from which the yarn may be easily unwound for further processing.
Another object of our invention is to provide a means for horizontally winding large yarn packages in which the tension variations in the yarn are reduced to a minimum and the resulting yarn is wound with substantially uniform tension.
Still another object of our invention is to provide a means whereby full yarn packages may be easily and quickly replaced by empty yarn supports or packages. Other objects of our invention will appear hereinafter from the following detailed description.
The formation of large packages of yarn is very desirable in many textile operations. Such packages may be used as supply packages for the formation of other large yarn packages in which the yarn characteristics, such as twist, may be varied and are also desirable for the reason that large yam packages decrease the number of knots necessary when the yarn is later used in warping or in weaving. In addition, the larger yarn packages require less frequent changing on twisting and warping apparatus and fewer spools are necessary for shipping a definite weight of yarn.
In order further to illustrate our invention, reference may be had to the accompanying drawings, in which Fig. 1 is a side view of one embodiment of our invention showing the path of the yarn,
Fig. 2 is a front elevation of this embodiment showing the spool spindle guide partly in section,
Fig. 3 is a vertical view of this embodiment,
Fig. 4 is .a side view of another embodiment of our invention,
Fig. 5 is a front elevation of this latter embodiment, and
Fig. 6 is a vertical view of the embodiment of our invention shown in Figs. 4 and 5.
Like reference numerals represent like elements throughout the several views of the drawings.
Referring now to the drawings, and particularly to Fig. 2, there is shown a spool 1 through which runs a spindle 8, the ends of which protrude beyond the spool and which are positioned in the spindle guides 9. The spool l rests upon and is driven by a cork roller l0 which acts as a friction drive, the roller I9 being in turn driven by shaft II which is operated by any suitable means, and which serves to drive a plurality of rollers Hi. In Fig. 1 the yarn l2 which is being twisted and wound on to the take-up package or spool l is led upward from a rotating twisting take-01f bobbin l3 through a pigtail guide l4 and over guide bar 15. The yarn I2 is then led through a traverse guide I6 which is attached to a reciprocating traverse bar ll, the reciprocation of which deposits the yarn evenly on the spool I.
The package isformed by setting an empty spool 'l in position as shown in Fig. 2 and permitting it to come in contact with and be driven by the rapidly rotating friction drive cork roller 10. The yarn is passed through the traverse guide [6 and is laid on the spool 1. As the spool 1 takes up the yarn the traverse bar I! reciprocates and the traverse guide 16 guides the yarn evenly on the spool. As the spool 1 becomes filled with yarn, it rides higher and higher on the driving cork roller l0 and the ends of the spindle 8 move in the spindle guides 9 to form or shape the yarn on the spool 1. When the spool is full it rises to the position A as shown by broken lines in Figs. 1, 2 and 3, and the spindle ends rise to the position 8'. The spindle guides 9 are supported as by brackets I8. The full spool of yarn may be removed by merely lifting it out of the yarn guides 9 and an empty spool may be dropped in place to wind the next package.
In accordance with another embodiment of our invention as illustrated in more detail in Figs. 4. 5 and 6, the empty spool 1 upon which the yarn is to be wound is supported on a spindle 8, the ends of which pass through arms l9 provided with holes 20 for receiving the ends of the spindle 8 andpermitting rotation therein without'loose movement. The arms l9 are pivotally mounted on a bar 2| by means of holes 22 and move freely about the bar 2|. On the left-hand arm I9 is attached a spring 23. as by rivets 24. the lower end of which spring bears against the end of the spindle 8 and maintains a light pressure thereon. Horizontal movement of the empty spool from the left to the right due to the light pressure of the spring 23 is prevented by contact of the bevelled base with the friction drive cork roller l0 mounted on shaft ll against which the spring 23 forces the base of the spool.
The package is formed by leading a yarn l2 on to the spool I. The yarn I2 is led upward from a rotating twisting take-off bobbin l3, through a pigtail guide l4 and over a guide bar IS. The yarn I2 is then led through a traverse guide l6 which isattached to a traverse bar H, the reciprocation of which deposits the yarn evenly on the spool 'I.
The spool I is driven or rotated by the cork f friction drive roller l0 upon which it rests as shown in Fig; 4. The roller I0 is turned by the shaft ll whichpasses through it, which in turn is driven by any suitable means which serves to drive a plurality of rollers Hi. When the yarn I2 is thrown on to the rotating spool 'I it proceeds to wind on the spool and it is evenly distributed along the length of the spool by the traversing guide l6 attached to the moving traverse bar I].
As the spool I becomes filled with yarn it rides.
in an increasingly higher position on the cork friction drive roller l0 since the arms I! holding the spool I are free to pivot about the bar 2|. As the spool I rides higher on the cork roller ID the base of the spool is held constantly in contact with the base of the cork roller l0. Since the traverse distance is constant, the spool being filled with yarn moves gradually to the right as it fills due to the spring pressure and the yarn is wound on the spool to form a yarn package of a particular controlled shape. When full, the package is in the raised position B and has the shape as shown by the broken lines in Figs. 4, 5 and 6. The full package may be removed by merely slipping the spindle 8 from the holes 20 in the arms l9 and it may be replaced in a similar manner by slipping the spindle of an empty spool in the holes.
Winding yarn packages by means of this device gives a package of very low tension differential which is ideally suited for many textile uses as hereinbefore stated. Spindle speeds of as high as 11,500 R. P. M. and higher may be easily employed using this surface drive method.
It is to be understood that the foregoing detailed description is merely given by way of illustration and that many variations may be made therein without departing from the spirit of our invention.
