My invention is directed to that type of pack age winder in which the reciprocating guide is carried by a laterally movable guideway and in which the package winding spindle is positively ll driven.
Heretofore in winding soft yarn packages where the reciprocating yarn guide pressed against thev package it has been diilicult to ob-' tain an even winding of the package because of the local pressure of the yarn guide. It has also been difficult to wind the package with an even tension because of this local pressure. It has also been hard to control the winding of the package at the ends thereof.
My invention comprises a novel and efllcient means particularly well adapted for the winding of soft yarn packages of even density throughout so that they will be suitable especially for use in knitting machines: this being accomplished by 90 providing a self-adjusting pressure roller which contacts with the package with a light pressure throughout the length of the package, and also package. as One object of this invention is to provide a self-adjusting roller of the above character which. will distribute the pressure over the entire length of the winding package instead of localizing the pressure at the point where the traverse guide usually presses against the packproviding the self-adjusting roller which contacts the winding package throughout its length the strand of yarn as it proceeds from the traverse guide to the pressure roll and package is carried to the desired limits of the traverse particularly at the beginning of the winding on the'empty core. This causes the relativeiy'bottom or lower layers of yarn to support the succeeding upper layers of yarn and thereby build up a superior formed package without the detrimental features, such as overlapping or overwilnlditng of the yarn at the ends of the package w c causes "press-oi! w us in h a knitting machine. m t e by permanently spacing the yarn guide from the age. This small amount of pressure surface by Another object of this invention is to provide means whereby moistened yarn may be successfully wound. It is well known that changes in the moisture content of the yarn during the winding process produced either by mechanical humidiiication or weather conditions, directly affect the material being woundsince it absorbs -more or less moisture; This moist material is ordinarily diflicult to control during thew'lndlng process but maybe very successfully wound when I the pressure is applied by my selL-adlirsting roller where the surface of the roller conforms to the surface of the winding package and the traverse guide is spaced from the surface of the package" t H.
Another object of this invention is to provide means for winding moistened yarn which will not squeeze out the moistening oil or other solution with which the yarn has been intentionally impregnated. This is accomplished by perma- 20 nently spacing the guide from the package, thereby preventing the guide from exerting pressure on the strand of yarn which is passing therethrough to the pressure roll'ami package.
- Another object of this invention is to provide means for winding the' yarn with a reduced tension by preventing the strand of yarn from being drawn between the face of the traverse guide and the winding package, thereby preventing frictional tension from being added to the 80 strand of yarn. This is accomplished by permanently spacing the traverse guide from the surface of the winding package and by providing means for keeping the pressure roller in contact with the surface of the winding package throughout the length of the package, thereby ensuring the same surface speed for the yarn, the surface of the pressure roller and the surface of the winding package without detrimental frictional interference.
Another object of this invention is to provide means whereby the self-adjusting roller will maintain an even pressure from one end to the other end of the package and thus prevent more pressure at one end than at the other end as the package builds up. It is well known that'when. winding some kinds of yarn there is a tendency forthe yarn to build up faster on the small and of a cone than on the largeend. This is due to.
the angle oi. the "lay" being sharper at the in) smaller diameter than at the larger diameter. If the roller were held in a relatively fixed position and not allowed to swing into conforming allnement with the surface of the building-up cone there would be a crushing oi the, prominent portion of the mass of yarn which would result in bulging .at the end of the package. The stated object of this invention is accomplished by providing means for adjusting the holder for the roller so that a selection of any one of several points of fulcrum can be made.
Another object of this invention is to provide for the selection of a roller from rollers of different shapes, and mounting the roller in a pivoted holder. When a cylindrical package is being wound a cylindrical roller could be used. When a conical package is being wound the roller could be conical, or cylindrical, as desired. The object 7 is to have the surface of the roller run at the same peripheral speed as the surface of the winding package.
Another object of this invention is to provide means for controlling the relative positionpf the traverse guide so that the guide never comes in contact with the surface of the winding package. The self-adjusting roller contacting with the winding package and mounted on the guideway provides means for controlling the location of the traverse guide.
Another object of this invention is to provide means which entirely remove'the pressure from the traverse parts, i. e., the guideway, guide bar, guide stud or roller, guide and cam, thereby reducing the amount of wear on these movable parts. This is accomplished by mounting the self-adjusting roller, which contacts with the winding package, in a holder that swivels on the guideway. In other winders as the package increases in diameter and the guide itself. comes in contact with the surface of the winding package the guide and adjacent parts are moved away by the pressure exerted directly on the guide and. the supporting guideway. This pressure necessarily creates friction of the moving and wearing parts. By eliminating the pressure entirely the life of the moving parts is greatly increased.
Another object of this invention is to provide means for preventing "loops" to catch and break out during the winding operation. This is accomplished by means provided by the roller contacting the surface of the winding package, said roller being mounted in a holder pivoted to the.
guideway. whereby the traverse guide ,is kept away from the winding package far enough so that loops cannot be caught on the said guide.
Practical embodiments of my invention are represented in the accompanying drawings, in which:
Fig. i represents an end view of a winding head embodying my invention, a conical core being shown in connection with a cylindrical pressure roller in the positions they assume as a conical package is about to be wound;
Fig. 2 represents a side view of the same;
Fig. 3 represents a detail plan view of the same;
Fig. 4 represents a detail plan view showing a conical core in connection with a conical pressure roller; and 4 Fig. 5 represents a. similar view showing a cylindrical core in connection 'with a cylindrical pressure roller.
The winding head which is pivotedto the frame at l comprises, generally, the cam shaft ousing 2 and the winding spindle shaft housing ii. The shaft of the winding spindle 5 is rotatably ounted in its housing 3 and may be driven the usual manner from a suitable source of p wer, not shown herein, through the pulley 6 and b t I. The core which may be conical, as shown a 8 in Figs. 1, 2. 3 and 4, or cylindrical, as shown at 8* in Fig. 5, may be secured in-the usual manner on the winding spindle 5. The shaft 9 of the cam III is rotatably mounted in its housing 2 of the winding head. This cam shaft 9 may be driven from the spindle shaft 4 through the gears ll, l2, pulleys l3, l4, and belt IS.
The laterally movable guideway I6 is pivoted to swing about the cam shaft 9, as usual, which guideway may be provided with a relatively fixed guide rod I! on which the hollow traverse guide reciprocating bar Ill slides. The inner end of this bar It is provided with a stud or roller l9 located in the groove of the cam Ill. The outer end of this bar I8 is provided with an uprising arm 2| to which the traverse guide 22 is attached. This guide 22 is permanently spaced from the package so that it will not contact therewith at any time during the winding of the package.
The self-adjusting roller may be cylindrical, ,as shown at 23 in Figs. 1, 2, 3 and 5, or it may be conical, as shown at 23* in Fig. 4. This roller which slightly presses against the package throughout its length as it is being Wound is driven by its contact with the package, and, in the present instance. this roller is shown as located between the package and the reciprocatin yarn guide. The pressure roller shaft 24 is re movably mounted at its ends in the laterally projecting arms 25 and 26 of a holder 21 adjustably fulcrumed on the laterally 'movableguideway IE to swing laterally with respect to the package for keeping the contacting peripheral surfaces of the roller and package in alinement throughout the length of the package.
In the present instance I have shown three alined fulcrumed points for the pressureroller holder 2'! by providing three vertical holes 28, 29, 20 in the top of the guideway, and three'corresponding vertical holes BI, 32, 33 in the holder V (shown in dotted lines in Fig. 2), together with a removable fulcrum pin 36 which may be in serted into any pair of holes according to where the fulcrum point of the holder is desired to be. 'For instance, when 'a cylindrical package is being wound the lay of the yarn and the density of the package would be the same at both ends thereof ahd the fulcrum point 'for the pressure roller holder should be at the middle pair of holes 29, 32. When a conical package is being wound with some kinds of yarn it would be desirable to have less pressure at thesrnall end of the package. In this event the fulcrum point should be at the pair of holes farthest from the small end, i. e., the .holes 30, 33. When it is desired to have less pressure at the large end of the paok'agethe fulcrum point should be moved to the holes 28, 3|, farthest from the large end.
The usual yarn bar is provided on the guideway for directing the yarn through the yarn guide and over the pressure roller to the backage. e
When it is 'desired to wind a conical package. as shown in Figs. 1 to 4 inclusive, either the cylindrical pressure roller 22 or the conical pressure roller 23' may be effectively used; and. when it is desiredto wind a cylindrical package, the cylindrical pressure roller 22 may be effectively used.
It will be understood that by the use of the term "yarn" I wish to include any other flexible material which can be wound effectively in my improved winder.
It is evident that various changes may be resorted to in the construction, form and arrangemerit of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the particular embodiments herein shown and described, but what I claim is:
1.
