WILTON, NEW HAMPSHIRE, A CORPORATION OF NEW HAMPSHIRE AUTOMATId WINDING MACHINE Original No. 1,700,425, dated January 28, 1929, Serial No.'153,132, fi1ed December 7, 1926. Application for reissue filed November 13, 1980. Serial No. 495,410.

This invention has to do with winding yarn, thread or other filament (hereinafter referred to as yarn) into traverse-wound packages, such as headless self-sustaining cops, balls or cheeses built up, as usual, of

layers of yarn lying in spiral or helical formation, reversals of the direction of pitch of winding occurring at the unsupported end faces constituted of these cusps or reversals. Such a package is suitable for war for weaving, for rewinding into other pac ages, for direct use in a warping, knitting, sewing, braiding or other yarn-using machine, or as weft for a continuoussweft loof. As well known to textile artisan-s, it is necessary to rewind yarn made on a spinning frame and wound on bobbins, for economy of handling and prevention of stop age of the yarn-using machine, into pac ages comprising a greater length of yarn that it is possible to wind on the spinning frame bobbin, which can contain a length much less only than that convenient to be used in the ball or cheese constituting the primary yarn supply for the yarn-using machine.

One object of this invention is to provide a machine adapted automatically to wind a self-sustaining headless package comprising.

the wound lengths of-yarn of a plurality of different spinning bob-bins or other primary unwinding containers wound on the headless package one after the other, and to provide a machine for this purpose requirin a minimum of attendance whlch shall be a apted to receive a number of unwinding supply packages, such as spinning bobbins or spools, to

- wind the contents of unwinding supply bobbins severally into' headless traverse-wound packages, and to cause thesesupplies several ly to be replenished automatically by new supplies when exhausted or broken.

In a preferred form, it is a further object of the invention to provide for automatically uniting the exhausted or severed winding end to the leading end of the fresh or replenishment supply; and to provide for tying these two ends to ether automaticall Leading to these ObJBCtS, subordinate 0 jects of the invention are to provide a. machine which will detect and remove-or dofi a complete headless package or cheese; to provide in such a machine automatic devices for dischargin a \spent unwinding package; to'provide in such a machine automatic devices for beginning winding on a fresh spindle, quill, tube or carrier of the leading end of a replenished unwinding supply; and to provide for automatically positioning a fresh unwinding package whenever a predecessor unwinding package is exhausted or its yarn is broken. A

A further object of the invention is to provide means to detect and remove knots, enlarging defects, snarls and other imperfections generally known and hereinafter referred to as slubs; or, in case of failure to remove a slub, to break the yarn supply and secure replenishment of the yarn supply; and to ,providemeans to detect breaka e or exhaustion of an unwinding su ply, an automatically to stop winding 0 ,the winding ackage of that supply until replenishment shall have occurred.

A further object of the invention is to provide a machine containing devices to secure some or all of the above objects which will provide for winding the desired kind of wound package during progress of the winding and unwinding yarn packages in a circulatory path and in which the replenishment mechanism, the, place of delivery of the completed packages, the place of delivery of the spent bobbins and the place of donning or placing a carrier for the winding yarn mass is at one end of the machine, these devices operating at a relatively stationary location.

In pursuit of these objects, the invention provides, among other features and characteristics, in a machine operatin to wind one package and unwind another uring travel of the winding and unwinding yarn supply, improved devices for supporting,tensionin detecting exhaustion or breakage of the winding arn,-and for stoppin the motion of the win 'ng package upon ex austion or breakage or the occurrence of a slub, or of any of these; and improved devices for traversing yarn to lay quick-pitched spirals on the surface of a winding container or package during travel along or about a winding machine.

The invention provides devices and com- 9 binations of devices for attaining the above and other objects, as well as improved forms of the subordinate combinations and elements of a machine automatically operating to wind the yarns ofa plurality of supply bobbins or other unwinding packages in a connected whole on-a container or ackage in the-form of a cop, ball or cheese uilt up of traverse wound layers.

For these purposes, the machine may also include many of the characteristic features and combinations of a machine invented by Edward J. Abbott and described in his apglication for patent for winding machines,

Attendance upon such a machirfie involves v carrying about the machine of heavy weights of fresh supplies of yarn and also involves delay in operation 'due to the necessity for providing at each winding pair (thereby meaning the unit of unwinding bob in or package, winding package, suppor s for these, traverse m'eans, guides and tensions for the winding yarn) means for stopping the operation either upon exhaustion of the yarn being wound or completion of the wound mass, until such time as the circulating operator of the machine can finish replenishing and piecing the supplies at the intervening stopped units and removin all. of the intervening and stopped finishe packages. This is wasteful of time and attendance and exhausting to the operators, and ineilicient 1n respect to the considerable idle time of winding pairs, lessening the full capacity of the machine, and causing the output of the machine to depend upon the activity and skill of the operators.

In the said application of Edward J Abbott, Serial No. 429,695 (Patent No. 1,609,- 639, December 7, 1926) it has been disclosed how to cause the winding pairs comprising a supply bobbin, a traverse mechanism, and a winding package in the form of a headless ball or cheese to progress about the machine so as to bring each winding pair at or about the time of completion of winding from the supply package to the relatively fixed station of an operator at one end of the machine.

F or these purposes the machine of the said application comprises among other things tractor rolls for'driving the winding package along which the winding pairs are pro' gressed during winding; a support for bobbins being unwound holdingthe bobbins in an erect position for'unwindng' from one end of the supply package; and a traverse guide and means for operating it causing rapid reciprocation of the traverse guide in the direction of progress of the winding package or cheese along the tractor rolls. In the machineof the said application the operations of replenishing the supply packages,

dofling the full cheeses, donning cores, quills or tubes for a new winding for another cheese, and uniting operations for joining the leading end of a supp-1y package to the following end of a winding package are manual operations adapted to be performed by the skilled operator at one end of the machine:

The present invention retains the advantageous mode of operationand construction of the machine of the said application in respect-to the arrangement of tractor rolls, the direction and mode of progress of the winding pairs first in one direction along one tractor roll and then in another direction along .or dofling the full cheeses; provides automatic means for placing on the winding spindles of the winding pairs a new carrier,

'core, .tube or quill; provides for automatically beginning winding on a new carrier or core for a newly begun package or cheese by .automatically delivering the fully wound package and the spent bobbin or carrier for theunwinding supply and replenishing them severally by a new core and a replenished un winding supply, and provides for automatically replenishing in respect to the winding carrier and spent supply by providing and positioning a new supply, and by automatically uniting the leading end of the new supply to the following end of a broken or exhaustedsupply or to a starting winding on the winding package carrier; and further provides for accomplishing these operations at one end of a circulating winding machine having the advantages of the machine of the said Edward J. Abbott application, by ac complishing the circulation about the machine of winding pairs in about the time required to wind allof the yarn oif of one supply package onto the forming cheese, so that in normal operation the unwinding carriers are exhausted when they reach the replenishing mechanism.

In a preferred form the machine, referring now to Figs. 1 and 2 of the drawings, comprises end frames 1 and intermediate frames 2 in any desired number shown as castings, see Fig. 3, having suitable seats for upper longitudinal rails 4, and rails 5. Other longitudinal struts may, if desired, be provided, for instance as shown at 6, to increase the strength and rigidity of the framework, which may be of any suitable form for supporting the working parts. A suflicient number of frames 2 is provided to'build a machine of the desired length, and this length may be dictated by'the length of the unbroken yarn on the usual unwinding packages, the speed of circulation of the winding pairs, and the linearspeed of winding-on the 5, these rails are bent, for example at 4, 5",

38 is driven as presently-described.

Referring to Figs. 1, 1, 2, 3, and 4,. the winding package is driven by driving contact with one or the other of the longitudinal tractor rolls 50, 51 which preferably-extend along the machine above the rails 4 between end bearings in brackets 52, 52 at the rear end of the machine and end bearing brackets 53.,

53 formed as a part of a hollow transverse gear casing 55 extending across the front end of the machine inward of the right end bearing frame, Fig. 1.

Casing 55 has appropriate bearings for like I short shafts 56 and 60 (of which shaft 56 maybe employed as a main driving shaft,

bearing for this purpose a pulley 57 driven.

78' to a secondary cam shaft 79, all in bearings in the frames 2. The left or back end of the shaft 79 carries a tappet cam 80 for use presently mentioned. The right or front-end of the shaft 77 carries a tappet cam 81 for use presently mentioned.

for example, at the rate of ten feet per minute.

The arrangement is such that the rapidly reci. rocating guide 126 projects into the path e yarn guided by t e guide 127 and the upper surface of one of the tractor rolls 50, 51, and by reason of the cam edges of the guide 126 picks up and reciprocates the yarn in a direction parallel to the winding axis.

- the travelling wound cheese is such as to minimize shock of contact and to'result in slight- 1y rotating the dolled wound mass and its
