Application March 25, 1955, Serial N 0. 496,848 11 Claims. (Cl. 28--28) textile winding machine sists of a creel, a size box, a dryer, a delivery roll and a winding winding on a succession of loom beams.

Heretofore, the slasher was beam was full of yarn ends.

The operator then cut the warp yarn ends, removed the as the other warp yarns. presents a problem of winding, cutting from a full loom beam, and fastening to a succeeding loom beam which does not exist for materials in sheet or web form. Moreover, the yarn ends have a certain amount of elasticity so that when the yarn ends are out under tension they must be held and they must also be held While fastening to a succeeding loom beam or otherwise the yarn ends will rebound and tangle. It is furthermore essential in winding yarn ends that the loom beam does not stop winding under tension during the positioning of the empty beam in the former position of the full beam otherwise the yarn ends will lose their tension and tangle. The mechanism according to the present invention recognizes stopped when each loom 2,856,67l Patented Oct. 21, 1958 the above problem and has succeeded in. providing an effective solution therefor.

Another object of the a win set of warps.

It is still another object of the present invention to provide a textile slasher with a beam-positioner and Wind- Incorporates have temporarily stopped teningof the warp yarn Another object of the sion of a winding and loom beam changing mechanism for cutting, fastening and winding yarn ends on a beam which is simple, rapid and effective for the purposes intended.

The above and other features, objects and advantages of the present invention will be fully understood from the following description considered in connection with the accompanying drawings.

elevation view of the loom. beam and Referring specifically to the drawings and more particularly to Figs. 1 and 5, the textile winding machine emmounts a pair of tail stocks 24 which are slidably removable in lateral arm 18.

42 is supported in bearings 43 depending from lateral arm 16. Hence, the motor 32 drives each head stock through sprocket 34, sprocket 38.

and finally sprocket 46 through clutch 44. It should be noted that the sprocket 34 drives both head stocks 26 separately and individually through clutch 44. The actual driving force applied to both loom beams is effected'by'means of a loom beam driving dog 46 which in Fig.5 is shown removably engaged withloom beam head 28a. Figs. 1 and 4 illustrate binder roll 4% and delivery roll 59 for the delivery of a multiplicity of parallel and individual warp yarn ends 52 to the textile winding machine embodying the present invention.

As clearly seen in Fig. 1 the warp yarn ends are wound on the right hand side of the figure while the empty loom beam 36 is positioned on the left hand side of the figure. Thus, loom beam 28 is rotated by means of winding power motor 32 since its associated clutch 44 is engaged, while loom beam. is stationary since its associat'ed clutch 44 is disengaged. After a given length of warp yarns have beenwoundonloom beam 28 its clutch is disengaged and the warp yarns 52 are clamped and cut in a manner to be described in detail hereinafter, and the yarn ends being furnished from the delivery roll of the textile slasher which. is still in uninterrupted operation are fastened to empty loom beam 30 by means which will be described more fully hereinafter. Thereafter, the lateral arms 16 and 18' are rotated by positioning motor 22 so that loom beam 30 takes the position formerly occupied by loom beam 28, the full loom beam 28 having been replaced by an empty loom beam which then has the position formerly occupied by loom beam 30. Thus,

there is a rotation of the lateral arms preferably of 180 but not necessarily limited thereto in order to change positions of the loom beams. Further details concerning the operation of our winding mechanism are clearly set forth in our parent application, Serial No. 411,746.

Referring more particularly to Fig. 4 and the left hand side of Fig. 1, the structure shown therein includes a tension positioner and accumulator roll 54 which is supported in a pair of guide members 56 having elongated vertical slots 58. The roll 54 rests on the warp yarns 52 coming off the delivery rolls, the roll 54 being free running in the slots 58 of guide 56. When the warp yarn 52 is being wound on a rotating loom beam the warp yarns are in the position shown in dotted lines in Fig. 4 in a more or less straight line to the rotating loom beam with the roll 54 in the top portion of the slots 58 and resting on the warp yarns 52. However, when both loom beams stop winding and the yarnendsarebeing cut and fastened to the empty loom beam, the yarn. ends being delivered fro-m the delivery roll ofv the textile slasher form a loop and the roll 54 freely movablein slot. 5%.

drops downward under the influence of gravity to continue to rest on'warp yarns 52' as shown in full lines in Fig. 4' thereby maintaining sufficient tension on the warp yarns 52 to prevent tangling of the individual yarns. Tension positioner and accumulator roll 54'also function to pull the yarn ends taut over the spindle of the empty loom beams in an even lay for fastening thereto. In addition, roll 54 acts to accumulate the excess yarn ends until the empty beam is ready to wind. When theclutch associatedwith the empty loom beam is engaged, the standard textile slasher drive will be operated at high speed to'build up preset yarn tension. Therefore, the accumulated yarn'ends' are wound rapidly on the loom beam and the roll 54 travels in slots 58 to its dotted line position and the loop of" yarn ends disappear. It should be noted that'the tension positioner and accumulator'roll 54 acts to always maintain sufiicient tension on the warp'yarn ends in order to keep them from tangling;

- functions to pull theyarn ends taut over the empty loom beam for fastening thereto; accumulates the warp yarn ends delivered by the delivery rolls 48 and 50 while both loom beams have temporarily stopped winding at'the time of cutting and fastening the warp yarn ends to the empty loom beam.

Referring now to the cutting mechanisms of the pres- 86 by means of a pin Y tener100 is provided with a lit) ent invention, the type of cutter illustrated in Fig. 2 is the electric resistance type which includes a metal tube 69 having an electrical resistance wire 62 therein but not in contact with the inner wall of tube 60. The electrical resistance wire 62 is supplied with electrical current through a transformer 63. Heat is conducted from the wire 62 through a material which is a conductor of heat and not of electricity (not shown) to the tube 60. Thus, the metal tube 6% when dropped into engagement with multiplicity of warp yarns will sever the same by burning or scorching through them. The electrical resistance cutter is mounted on a frame 64 through springs 66. The mechanism for elevating and lowering the cutter frame and cutter consists preferably of a piston 68, a cutter latch and a cutter knock-off 72. As seen in Fig. 1 an upper draw bar 74 and a lower draw bar 76 serve to tension the warp yarns over the lower bed 78. The upper bed 80 upon the lowering, of the cutter to a position in close proximity but not touching the warp yarns 52 is further dropped into clamping engagement with the warp yarns '52 by means of an electrical actuator 82 (Fig. 2). Thus, the actuator 82 translates the upper bed 89 the remaining distance necessary for it to contact the lower bed 7 8 and clamp the-warp yarns therebetween The cutter is also translated by the actuator 82. Ac-' cordingly, at or just precedingcontact of the upper andlower beds the cutter latch 7 0 is disengaged thereby permitting the cutter to drop freely through the warp yarns and thereby sever the warp yarns by burning. Thereafter the actuator 82 is de-ene'rgized and springs 66 due to their natural resilience raise upper bed 80 and through a motion multiplier 84 and the cutter itself. is elevated away from engagement with'the warp yarns 52.

Another type of cutter for employment with the present invention is seen in Figs. 3 and 3a. The cutter shown therein is a knife cutter having a groovedsupporting element 86 provided with a fixed shear blade 88 which is permanently mounted in the grooveof supportingelement 90. Also mounted in the groove of supporting element 86 and juxtaposed to fixed blade 88 is a reciprocating blade 92 which is connected to a vibrator 94. Thus, vibrator 94 causes the movable blade 92 to move rectilinearly against the fixed blade 88 and when the warp yarns are forced into the arcuate openings of the blades 88 and 92 the cuttingedges thereofeffectively sever these warp yarns. It'should be-understood that the same mechanism utilized for elevatingand lowering, the cutter illustrated in Fig. 4 is used for this alternate type of cutter. It is preferable to have a fairlead roller 96' on theside of'the cutter remote from the slasher delivery rolls in order to guide the warp yarns on loom beam.

Referring now in particular to the fasteningmechanism as seen in Figs. 1. and 5; the structure comprises an arm 93 which may be pivoted to the cutter framework structure. Mounted in the arm 98 is a solenoid for actuating the fastener 100 having a fastening shoe 102. The fascollar 104 and a driving. spring 106 contained between the collar 104 and the arm 98 and another collar 108 havinga rebound spring 110 trapped between the collar 108 and the arm 98. A han dle 112 is utilized in order to manually lift and lower the fastener from and to striking position. As seen in Fig. 6, "the fastener shoe referred to generally by the numeral 182 includes an elongated arcuate clamping member 114 which is secured to laterally movable elements 116 on each end thereof by'means noted that movable elements 116 are bevelled at their lower outer edges 120 which co-act with the bevel on the inner edge of the loom beam heads28a thus facilitating the driving of the fastening shoe into engagement with thewarp yarn ends and thereby forcing the latter into securement on the adhesive backing fixed to the loom beam" ends inv an even Since the length of the fastening shoe/1'02- spindle while roll 54 maintains the yarnv lay thereon.

to the filling of springs 118. It should'be beam commences is variable the fastening shoe 102 is easily driven into and removed from between the loom beam heads 30a of loom beam 30. It is within the scope of our invention to provide other means on the loom beams for securing the 'severed warp yarn ends thereto.

Referring more particularly to Figs. 7 and 8 wherein is shown the assembly in detail employed with the electric resistance cutter illustrated in Fig. 2, it being understood that only the cutter latch 70 of the assembly is shown in bro-ken lines on Fig. 2. In this regard, a support member 75 is secured to upper bed 80. Journalled through support member 75, cutter latch 70, and holdback hooks 81 is a shaft 73. It should be understood that cutter latch 70 as well as holdback books 81 are adapted to rotate in a direction transverse to the axis of shaft 73. Thus, upon downward movement of the upper cutting bed, the assembly shown in Figs. 7 and 8 is carried along. Holdback hooks 81 engage motion multiplier arms 84 near offset rollers 83 and prevent the multiplier arms 84 from pivoting. However, when the cutter is lowered to a particular position proximate to the warp yarns 52 the cutter latch 70 is pivotally disengaged from the cutter knockoff 72 and the holdback hooks 81 are also pivotally disengaged from multiplier arms 84 thereby permitting the multiplier arms 84 to pivot about pivot points 85 while rollers 83 abut the fixed portion of the cutter. Through the action of the cutter as described the cutter undergoes a free fall movement in a downward direction and a multiplied movement in an upward direction; and the cutter itself moves a greater distance than the movement of the upper bed 80.

The sequence of operation of our invention is as follows: when one loom beam is wound full of warp yarns, the clutch associated with that beam is disengaged thereby stopping the rotation thereof. The clamping mechto clamp the warp yarns between The cutter is then lowered across the warp yarns thereby severing them and releasing the full loom beam. While the clamping mechanism still holds the severed ends of the warp yarns the textile slasher delivery roll continues to deliver Warp yarns which slack is taken up by the tension positioner and accumulator roll so that an even lay of warp yarn ends on the empty loom beam is effected. The fastening shoe then forces the yarn ends against the adhesive backing on the empty loom beam to thereby secure the same thereto. The clutch on the empty loom beam is then engaged and the empty loom to Wind. The full loom beam is then replaced with an empty loom beam and the whole unit rotated so that the loom beam positions are interchanged.
