assignors to The Conolon Corporation, a corporation of California Filed Aug. 26, 1966, Ser. No. 575,456 Int. Cl. B65h 81/06 US. Cl. 29-208 25 Claims ABSTRACT OF THE DISCLOSURE A device for automatic pattern wrapping of a fishing rod or a like article having a rotating circular head with a sector-like opening and dual drive means to bridge the opening so that the rod may be moved laterally in and out of the rotating head.

This invention relates in general to yarn handling apparatus and, more particularly, to a machine for winding yarn about several portions of a fishing rod or like object.

At the present time the manufacture of fishing rods is largely a hand operation. One of the most time-consuming hand operations is the winding of plastic or otherwise impregnated yarn about a rod to secure the line guide eyes in position, to cover a portion of a ferrule, or to secure a rod tip. In conventional practice, the entire rod is machine or hand-rotated while yarn is hand fed to be wound about it. This has remained a hand operation despite the great volume of fishing rods produced because many hundreds of models, of different lengths, diameters, elastic properties, and numbers of eyes and fittings are produced.

It is, therefore, a main object of this invention, to provide a wrapping machine which is versatile in that it may be easily set up to wrap a wide variety of fishing rods in different places with diiferent lengths, sizes, and types of wrappings.

Another object of this invention is to provide a substantially automatic rod wrapping machine which wraps and ties off the end of each wrapping.

A further object of this invention is to provide a rod winding machine in which the eyes to be wound and secured to a rod are automatically aligned and positioned along the rod so that alignment inspection of the eyes is not required.

Still another object of this invention is to provide a machine to rapidly and simultaneously wind yarn about a large number of positions along a rod.

Yet a further object of this invention is to provide a winding machine for rod-like objects which allows the object being wound or wrapped to remain stationary to be supported along its entire length.

A still further object of this invention is to provide a winding machine for elongated objects which may be easily loaded with objects to be Wound or wrapped.

A feature of this invention is the provision of a winding head to wind a given portion of a rod, the winding head having a sector gear with an open center and a radial opening leading to the open center, said sector gear being rotatably mounted about an opening in the winding head, the winding head having two drive gears at different positions so at least one drive gear always meshes with said sector gear, said sector gear carrying a yarn supply to wrap a rod placed in the open center of said sector gear through the radial opening in said sector gear.

Another feature of this invention is to provide, in a rod wrapping machine in which a rod is whipped with at least one strand of yarn, a tie-01f device for drawing 3,448,506 Patented June 10, 1969 an end beneath the whipping to tighten and lock the whipping.

It is an object of the invention to provide a device which with the rod may be wound by several turns of yarn and then will seize and draw a final turn beneath some preceding turns to tighten, lock and sever the yarn at the end of the winding.

Many other objects, advantages, and features of invention reside in the particular construction, combination, and arrangement of parts involved in the embodiments of our invention and its practice otherwise as will be understood from the following description and accompanying drawings wherein:

Referring to the drawings in detail, FIGS. 1 and 2 show a machine bed 40 supported by the legs 41. Two end plates 42 and 43 extend upward from bed 40 and have the pair of support rails 44 extend between them. Mounted on the rails 44 is the winding station generally designated by the reference numeral 45 and the winding stations designated by the numeral 45. The winding stations 45' and 45 may be positioned where windings are to be made by sliding them along and fixing them to the rails 44. A rod 39 to be wound extends through the winding

stations

45 and 45 and is held at each end by

suitable supports

37 and 38.

Each winding station 45' and 45 has a winding station frame 46 on which there are slidably mounted the two winding heads 47. The winding heads 47, which will later be described in detail, are moved towards or away from the winding station frames 46 by right and left

hand barrel cams

48 and 49. The

barrel cams

48 and 49 are mounted on a single cam shaft 50.

Pulleys 51 are mounted on the winding head drive shafts 53. The pulleys 51 drive the winding heads 47 by means of link belts 52 or the like. Shafts 53 are preferably splined shafts on which the pulleys 53 can move longitudinally with movement of the winding heads 47 and when positioning the winding stations 45' and 45. The shafts 53 are journalled in the end plates 42 and 43 and extend through the end plate 42.

As shown in FIG. 2, shafts 53 have the bevel gears 54 mounted on them beyond end plate 42. Cam shaft has a bevel gear 55 mounted on it.

Side plates

56 and 57 have the

lateral drive shafts

58 and 59 journalled in them. Shaft 58 carries the bevel gear 60 to drive bevel gear 55 and shaft 59 carries the pair of bevel gears 61 to drive the shafts 53 in opposite directions.

Referring further to FIG. 2, a motor 62 having reduction gear box 63 drives shaft 59 by means of the

pulleys

64 and 65 and belt 66. Within a drive gear box 67, shaft 59 has a spur gear 68 and a solenoid clutch engaged pulley 69 mounted on it. Within gear box 67 shaft 58 has the solenoid clutch activated spur gear 70 and the pulley 71 mounted on it. Belt 72 enables pulley 69 to drive pulley 71. The spur gears 68 and 70 mesh to drive each other. The sequence of operations of this drive will be hereinafter explained.

As shown in FIG. 5, each winding station 45 of 45 has a winding station frame 46 mounted on the rails 44. Frame 46 is generally U-shaped with a pair of opposed air cylinders 75 mounted on each side. Rod clamping piston rods 76 extend toward each other to secure a rod 39 extending through each frame 46. The outwardly extending ends of the rods 76 of the cylinders 75 activate limit switches 77 when a rod is clamped. The central bottom portion of frame 46 contains a large opening 78. Guide rods 79 extend downward from frame 46. A long air cylinder 80 has its upper plate 81 slidably secured by the guide rods 79. Cylinder rod 82 of cylinder 80 is fixed to frame 46 so activation of a cylinder 80 will cause it to retract its cylinder rod 82 to slide cylinder rod 80 upwards along guide rods 79. Upper plate 81 then approaches the bottom of frame 46 to thrust eye holder rod 84 and eye holder 83 through opening 78. In this position, upper plate 81 activates a limit switch 85.

As shown in FIGS. 12, 13 and 14, each winding head 47 has a frame plate 86 having two guide rods 87 fixed to project from the upper and lower guide

rod securing apertures

88 and 89. As may be seen in FIG. 5, four apertures 90 are provided in frame 46. Each winding head had two rods 87 extending slidably into a diagonally opposite pair of apertures 90. This slidably mounts two frame plates 86 on each side of each frame 46. A cam follower 91, shown in FIGS. 12 and 13, is fixed to each frame plate 86 and engages the groove 92 of a

barrel cam

48 or 49 as shown in FIG. 18.

Referring further to FIGS. 12, 13 and 14, a circular bearing 93 having a retaining lip 94 is fixed in frame plate 86 about the circular opening 95. A sector gear 96, having a radial opening 97 corresponding to the radial opening 98 in plate 86, is rotatably mounted on bearing 93. A first drive gear 99 is mounted on a common shaft 100 with a pulley 101 which is driven by a belt 52 as has been described and is shown in FIGS. 1 and 5. Drive gear 99 meshes with the teeth 102 of sector gear 96 and with the rotatably mounted idler gear 103. Idler gear 103 drives the second rotatably mounted drive gear 104 which also meshes with the teeth 102 of sector gear 96. The identical drive gears 99 and 104 contact sector gear 96 a greater distance apart about its circumference than the width of opening 97 so that a drive gear 99 or 104 is always in contact with the sector gear 96.

As shown in FIGS. 12, 13, 14 and 15, a yarn holding and feeding bracket 105 is fixed to the outer edge 106 of sector gear 96 and projects inward toward the center of rotation of sector gear 96. A thread or yarn bobbin shaft 107 extends from bracket 105 parallel to the axis of sector gear 96 in the direction of plate 86. A snap fastener type retainer 108, shown in FIG. 14, may secure bobbin 109 in place as shown'in FIG. 15. A yarn end 110 from bobbin 109 leads from bobbin 109 through a first aperture 111 and back through a second aperture 112 in bracket 105. The yarn 110 then passes over to and upward out of a quick threading slot 113 to emerge from the end of bracket 105 under a thread tension spring 114.

Referring now to FIGS. 5, 6 and 7, the tie-off portion of the first embodiment of our invention consists of a yoke 116 on each side of frame 46 within which a flap assembly 117 is slidably mounted to be moved laterally by an air cylinder 120. A flap 119 is hinged to be lowered by the activation of a pivotally mounted air cylinder 118. When the flaps 119 are lowered, the limit switches 12] are closed by an extension 122 on cylinder rods 123.

As shown in FIGS. 8 and 9, a tie-off head 124 is fixed to the end of each hinged flap 119. Each head 124 contains a piston 125 in a cylinder 126 connected to a rod 127. Rod 127 is connected to plunger 128 by means of a rigid link 129 so that air introduced into

tubes

130 and 131 will move piston 125 to retract or extend plunger 128 from tube 132. Plunger 128 contains a lateral slot 133 to receive a strand of yarn 110. It is to be noted that tube 132 and plunger 128 lie parallel to and adjacent to a rod 39 when the flaps 119 are urged into a down" position by cylinder 118.

FIGS. 19 and 20 show solenoid activated valves 135 of the type which may be used to operate the first embodiment of this invention. As shown in FIG. 21, an air pump 136 supplies a reservoir of compressed air to a pressure storage tank 137. From tank 137 a tube 138 is connected through the solenoid activated valves 139-150 to the manifolds 151-162. The manifolds 151-162 and similar additional manifolds (not shown) are connected to the air cylinders as will be hereinafter described.

The first embodiment of our invention is used and operates in the following manner. As may be seen in FIG. 1, a rod 39, which is to have eyes 164 similar to those shown in FIGS. 3 and 4 wound to it, is placed downward through the openings 98 of each winding head 47. This rod 39 is first secured in position by having its ends rest on the

supports

37 and 38. The winding stations 45' and 45 have been previously positioned along the rails 44 to attach eyes to rod 39 exactly where desired. The operator manually reaches below the rails 44 to place an eye 164 in each eye holder 83.

As shown in FIGS. 3, 4, and 11, each eye 164 has a line guide ring 165 which, in many cases, is connected by members 166 to front and rear extending attachments elements 167. The eye holders 83 have

suitable slots

168 and 169 cut in them to accommodate the particular eyes 164 being attached at each winding station 45' or 45. To allow rapid change in rod models being wound, eye holders 83 may easily be changed on the eye holder rods 84 to accommodate different sizes, types, and styles of eyes 164. An electric trimmer and counter, which is a standard type of a conventional pre-programmed control unit (not shown) counts and controls the following sequence of events. Valve 141, shown in FIG. 21, is opened to the position shown in FIG. 19 to pressurize manifold 153. Manifold 153 is connected by the tubes 171 to the outer ends of the cylinders 75 to extend the rod clamps 76 inward as shown in FIG. 5. This centrally grips the rod 39 in each winding station 45' or 45. When the rod 39 is so gripped, all the switches 121, as shown in FIG. 5, are closed to signal the control unit to then open solenoid valve 139 and pressurize manifold 151. Manifold 151 is connected to the tops of the cylinders 80 by the flexible tubes 170. Air pressure than activates cylinder 80 to raise eye holders 83 and eyes 164 through opening 78 and hold the attachment elements 167 of the eyes 164 against the bottom surface of the rod 39. The completion of this motion of cylinders 80 closes the switches 85 to signal the control unit to start the winding operation.

As shown in FIG. 15, a yarn 110 projects from the end of each bracket 105 and this yarn end has been clamped between the attachment elements 167 of the eyes and the bottom of rod 39 as the eyes were lifted into position. As shown in FIGS. 1 and 2, motor 62 is running constantly during the operation of the first embodiment of this invention, so the clutch 69, two clutches 172, two clutches 173, and one clutch 174 are engaged to allow motor 62 to drive the two shafts 50 and the shaft 53. Shafts 53 drive and rotate all the sector gears 96 in the manner which has been described. As the sector gears 96 rotate about the rod 39, the

barrel cams

48 and 49 move the winding heads 47 away from the center of each eye 164 to wind yarn 110 about it as shown in FIG. 3.

Referring now to FIGS. 1 and 16, a cam 177 is mounted on portion 175 of shaft 53 to activate a switch 176 once for each revolution of shaft 53. After a given number of turns are wound or before winding starts, the control unit opens

valves

150 and 143 to pressurize manifolds 155 and 157 shown in FIG. 21. Tubes 180, fragments of which are shown attached to the manifolds 155 and 157, lead to the outwardly disposed ends of the cylinders 118 as shown in FIG. 5. The cylinders 118 are thus activated to lower the hinged flaps 119 to place the tubes 132 of the heads 124 alongside the rod 39.

It is to be noted that winding station 45' may be required to secure a larger eye 164 than the winding stations 45 so that station 45' is controlled and activated somewhat separately from the stations 45. Thus, as shown in FIG. 21, valve 145 may be activated a head of valve 148 to pressurize

manifolds

159 and 161. The

manifolds

159 and 161 are connected by tubes 181 to the cylinders 120 of the winding stations 45' and 45. These cylinders 120 slide the flap assemblies 117 laterally to thrust the tubes 132 and the plungers 128 longitudinally past the portions of the rod 39 being wound. This motion of a tube 132 is shown in FIGS. 22 and 23.

As may be seen in FIGS. 6, 7 and 8, each tube 181 is connected to a cylinder 120 through a constrictor 184 and each tube 181 is directly connected to a head 124 by a tube 130. The constrictor 1'84 restricts flow through it so that plunger 128 is extended from tube 132 before the advance is completed of tube 132 past the winding of a yarn 110.

As shown in FIG. 24, yarn is wound about rod 39 and tube 132 with the last turn of yarn 110 falling into the transverse notch 133 of plunger 128. As has been described in connection with FIG. 16, switch 17 6 indicates revolutions of shaft 53 and thereby winds of yarn 110 about rod 39. Thus, when the yarn 110 is wound as shown in FIG. 24, the control unit disengages

clutches

173 and 174 shown in FIG. 1. Switch 176 signals the control unit to open these clutches so that the sector gears 96 of the winding stations 45 stop indexed in the position shown in FIG. 12.

If winding station 45 must make a longer wind for a greater distance to secure a larger eye 164, clutch 172, shown in FIG. 1, will be disengaged after

clutches

173 and 174 along with clutch 69 shown in FIG. 2. When all the winding heads 47 have stopped, the control unit closes

valves

145 and 148 and opens

valves

146 and 147 as shown in FIG. 21 to

exhaust manifolds

159 and 161 and pressurize

manifolds

160 and 162. These manifolds are connected to tubes 186 which are also shown in FIGS. 6 and 7. The tubes 186 are connected to the inner ends of the cylinders and they are connected by the tubes 131 to the heads 124 as shown in FIG. 8. Since the constrictors 184 only allow air to slowly exhaust from the cylinders 120 while the tubes 1'81 and rapidly exhaust the plunger extension sides of the heads 124, the plungers 128 are retracted in the tubes 132 to grip the last winding of yarn 110 wound in slot 133 against the end of tube 132. As air slowly exhausts from the cylinders 120, the tubes 132 are withdrawn from under the windings Wound over them to pull these windings tight as shown in FIG. 25.

As may be seen in FIG. 7 when the tubes 132 are all completely withdrawn, the switches 187 are closed to signal the control unit to close valves 143 and and open valves 144 and 149 to pressurize manifolds 156 and 158. These manifolds are connected to the inner ends of the cylinders 118 to cause the cylinders 118 to raise the hinged flaps 119. In some applications of this embodiment of our invention, this motion of plunger 128 and the tubes 132 may be used to break or sever the yarn 110 to complete a tied 01f winding as shown in FIG. 26.

If desired, referring to FIGS. 27, 28, 29 and 30, each winding head 47 may have a pair of short stroke air cylinders 1'88 and 189 fixed to its face in the direction of winding.

Arms

190 and 191 are pivotally mounted between the pairs of

lugs

192 and 193. A fixed arm 194 holds a cylindrical guide 195 clear of the front of the windings of yarn 110. Arm 191 is connected to the cut-off tube 196 which is slidably disposed in guide 195. Arm 192 is connected to the cut-off plunger 197 which contains the lateral slot 198.

by bracket 105. This is accomplished by providing slot 198 with a cutting edge 199 and a blunt gripping edge 7 200 as shown in FIGS. 29 and 30. Cylinders 1'88 and 189 may be activated by the control unit by means of valves and manifolds similar to those which have been described.

An additional advantage of the provision of the tubes 196 and the plungers 197 is that yarn ends are held in position to be clamped between a rod 39 and eyes 164 during the next cycle. Also, these yarn ends may be held by tubes 196 and plungers 197 a. lateral distance equal to one or two turns in the direction of winding at the start of the winding to ensure the overwinding and the tight winding of the starting ends. After winding starts, plunger 197 is extended and tube 196 withdrawn. In some applications of the first embodiment of this invention, two tubes and

plungers

196 and 197 are provided side by side. One tube and plunger holds the yarn end and the adjacent tube and plunger cuts the yarn end. It is also to be noted that the positive holding of a yarn end at the start of a winding by a tube 196 and a plunger 197 allows a ferrule to be wound on a rod or any other winding to be made on a rod where the yarn end cannot be clamped against the rod by an eye.

After the flaps 119 have been retracted,

valves

139 and 141 close and

valves

140 and 142 open to pressurize

manifolds

152 and 154 as shown in FIG. 21. These manifolds are connected by the

tubes

202 and 203 to the

cylinders

75 and 80 to retract the rod clamps 76 and lower the eye holders 83 as shown in FIG. 5.

FIG. 17 shows a decorative winding 204 having tightly wound portions 205 and spaced apart windings 206. This may be accomplished by using earns 48 as shown in FIG. 18.

Portions

207 and 208 of groove 92 have a greater slope to more rapidly advance a winding head 47 to pro duce the spaced windings 206. Thus suitable earns 48 can produce any winding desired with greater accuracy and uniformity than is possible by hand. In general, gear box 67 rotates the sector gears 96 about forty times for each revolution of a

barrel cam

48 or 49.

To start another winding cycle, the winding heads 47 must be returned to their starting position. As shown in FIG. 2, the clutch mounted pulley 69 remains disengaged while the clutch mounted gear 70 is engaged to rotate shaft 58. Since shaft 58 is now driven by meshing

gears

68 and 70 rather than by the link belt 72, it is driven in reverse and at a higher rate of speed. Switch 176, shown in FIG. 16, signals the control unit when the cams 148 and 149 have been reversed to their original position. Clutches 172 remain open so that the sector gears 96 do not revolve while the winding heads are being automatically re-positioned for the next cycle.

The second embodiment of our invention 'winds rods in much the same manner as the first embodiment which has been described. However, the second embodiment is even more flexible and more readily adjustable to wind a greater variety of rods or other articles.

Referring now to FIG. 31,

longitudinal ways

300 and 301 are fixed to the channel iron base 302, Two rack gears 303 and 304 are disposed adjacent to the

ways

300 and 301 and are engaged by the pinion gears 305 and 306 mounted on the shaft 307. Shaft 307 is journalled in the support blocks 310 and 311 which slidably rest on the ways "300 and 301. Shaft 308 telescopes within shaft 307 so that it may be extended therefrom and rotated by handle 309 to slidably position the winding station, generally designated by the reference numeral 312, along the base 302.

This second embodiment of our invention may have several winding stations 312, althoughsome may be modified or simplified in a manner which will be described. Each winding station 312 has a base plate 313 on which a hollow main frame 314 is fixed to extend upward. Drive mount frames 315 and 316 extend rearwardly from main frame 314, frame 315 being mounted on base plate 313 and frame 316 being fixed to main frame 314.

On the'drive mount frames 315 and 316 there are 8 I fixed motor mounts 317 and 318 having reversing two

speed motors

319 and 320 fixed on them. The shaft 321 of motor 319 drives shaft 322 through the combination clutch and brake unit 323. Through a pair of belevl gears 32-4 shaft 322 drives a horizontal splined shaft 325 which extends forward from a narrow central projection 326 of main frame 314 as shown in FIG. 31.

The rear portion of shaft 321 of the double-ended motor 319 has a vari-drive pulley 326 mounted on it. Pulley 326 drives pulley 327 by means of a belt 328. The turning of a handwheel 329 varies the ratios of the pulleys 326 and 327. Pulley 327 is mounted on shaft 330 of a three hundred to one gear reducer 331. Shaft 332 of gear reducer 331 extends into gear box 333 which is shown in FIG. 37 and will later be described in detail. By means of belt 334 and

pulleys

335 and 336, gear box 333 drives shaft 337 which extends into the program box 338-.

A rod gripping mechanism 339 is fixed in the center of main frame 314. An eye positioning mechanism 340 is also fixed to main frame 314. These mechanisms, which will be described in detail, are shown in FIGS. 32 and 39, respectively.

Fixed on drive mount frame 316 connected to shaft 341 of motor 320 is the combination clutch and brake 342 on which is mounted a pulley '343 driving pulley 344 by means of a belt 345. Pulley 344 is mounted on a shaft driving a horizontal splined shaft (not shown) which extends away from the viewer as shown in FIGURE 31. This shaft, which is similar to shaft 325, drives the winding head 346 in a manner which will be described. Through the vari-

drive pulleys

347 and 348 and belt 349, motor 320 drives shaft 350 through the three hundred to one gear reducer 351. Shaft 340 extends into a second gear box 352 having a pulley 353 driving a pulley 354 by a belt 355. Pulley 354 is mounted on shaft 356 which extends into the program box 357.

Referring now to FIGS. 31 and 33, guide

rods

360 and 361 extend from both sides of projection 326 of main frame 314. The winding heads 346' and 346, respectively, are slidably secured on these

rods

360 and 361 in front and behind projection 326, as it is shown in FIG. 31. The winding heads 346' and 346 are identical except that head 346' is installed inverted and thus reversed compared to head 346. Each winding head has a flat frame plate 362 having a circular bearing 363 about which a sector gear 364 is mounted about an opening 364' as in the first embodiment of this invention. The splined shaft 325 extends slidably through and rotates the first drive gear 365. An idler gear 366 rotatably mounted on shaft 367 drives the second drive gear 368 mounted on shaft 369 to mesh with the teeth 370 of sector gear 364. Sector gear 364 has secured to it to rotate with it a yarn holding and winding bracket 371 similar to that described for the first embodiment of this invention. Thus it may be seen that motor 319 may drive sector gear 364 of winding head 346' shown in FIG. 33, and in the same manner, motor 320 may drive winding head 346 shown in FIG. 31.

Each winding head has a tie-off tube 374 fixed to a finger 375 slidably mounted in block 376 fixed on the end of the piston rod '377 of air cylinder 378. Guide rods 379 extend through the bracket 380 which mounts cylinder 378 on frame plate 362 to prevent rotation of block 367 and keep tube 374 properly oriented. Tie-off plunger 381 extends through tube 374 and is attached to the slidably mounted finger 382. An air cylinder 384 in block 376 slides finger 382 by means of the rigid link 385 and rod 386. A hydraulic cylinder 387, by means of a link 388 and a rod 389 may urge the

finger

375 and 382 towards each other compressing spring 390 to extend the tie-off plunger 381. Thus the

cylinders

384, 387, and 378 may position, longitudinally advance, and withdraw tube 374 and plunger 381 to tie-off a winding 9 in the same manner described in connection with FIGS. 22-26.

The pair of winding heads 346 and 346' are moved away from each other while winding an eye 164 by a spur gear 391 shown in FIGS. 31 and 36. The gear 391 is driven by gear box 333 and extends into the two

apertures

395 and 393 in projection 326. From the winding head 346 a lower guide rod 394 extends slidably through aperture 393 and from winding head 346. A lower guide rod 394 extends into aperture 395. Rod 394 has a flat surface 395' to clear the teeth of gear 391 so that it may slide freely in aperture 395. Rod 394 has rack gear teeth 396 out in it to be engaged by gear 391. Thus rotation of gear 391 moves winding head 146' laterally. A similar gear (not shown) in the upper part of projection 326 engages an upper guide rod from winding head 346 to move it laterally. This gear is driven from gear box 352 by motor 320.

The second embodiment of our invention is used and functions in the following manner. The winding station 312 is positioned by handle 309 where an eye, similar to that shown in FIGS. 3 and 4, is to be wound to a rod. As shown in FIGS. 31, 32 and 39, cylinder 398 is extended to lower eye holder 399 to clear the front facing openings 400 in the winding heads. A rod 401 is inserted through the openings 400 in the winding heads and the cylinders 402 are activated to retract their rods 403 which have rack gear teeth 404 formed above and below their outward facing ends. A bracket 405 is fixed to frame 314 and has the jaws 406 and 407 pivotally mounted on it about the

shafts

408 and 409.

Sector gear teeth

410 and 411 on jaws 406 and 407 engage the rack gear teeth 404 on rod 403 so withdrawal of rod 403 closes jaws 406 and 407 to clamp rod 401 as shown.

Referring now to FIGS. 3, 4, 31, and 39, an operator places eyes 164 in the lowered eye holder 399 which is similar to that described for the first embodiment of this invention. Cylinder 398 is then activated to draw rod 415 inward and pivot arm 416 upward in bracket 417. Cylinder 418 is fixed to the outer flange 419 of arm 416 and, when arm 416 is raised, extends rod 420 to horizontally move an eye in holder 399 inward against a rod 401.

As shown in FIGS. 31 and 37, both

motors

319 and 320 are started. The clutch and

brake units

323 and 342 have their brakes and their clutches disengaged. Motor 319, through the vari-drive pulleys 326 and 327, drives shaft 332 extending into gear box 333. Shaft 332 has a solenoid clutch activated pulley 421 and a spur gear 422 mounted on it. Shaft 423 has pulley 355 mounted on it outside gear box 333 and, within gear box 333, it has pulley 424, a solenoid clutch 425, a spur gear 425, and a solenoid clutch 426 associated with it. Clutch 425' may drive shaft 423 on which is mounted the spur gear 391 shown in FIG 36. A link belt 427 passes about pulleys 421 and 424.

By means of belt 334 and

pulleys

335 and 336, gear box 333 also drives shaft 337 which is supported in bracket 428 and extends into control box 338. As shown in FIGS. 37 and 38, a number of disks 429 are mounted on shaft 337 within control box 338. Each disk 429 has a radial notch 430 cut in its circumference down to a pair of peripheral grooves 431 cut in each face. A contact element 433 may be positioned about the disks 429 and clamped where desired by means of a screw 434. Each disk 429 has an associated switch 435 which is activated by a contact element 433. Thus, as a winding operation takes place, the sequence of events to be described is controlled by the switches 435 which engage and disengage solenoid clutches and activate air valves (not shown) similar to those described in connection with the first embodiment of our invention.

At the start of the winding operation, clutches 426 and 425' are engaged along with the release of the brake and the engaging of the clutch of unit 323. Thus, as shown in FIG. 31, motor 319 drives the spline shaft 325 through the bevel gears 324; and shaft 325, in. the manner which has been described, drives sector gear 364 of winding head 346' to rotate bracket 371 about a rod 401 and make a winding. The rotation of shaft 423' rotates gear 391 as shown in FIG. 36 to move winding head 346' laterally as yarn is wound. It is to be noted that the rate of lateral motion of head 346 during winding may be adjusted by means of handwheel 329 which controls the vari-drive pulleys 326 and 327.

As winding continues,

cylinders

378, 376, and 387 are activated to cause the tube 374 and plunger 381 to become overwound and then tie off a winding in the same manner as has been described for the first embodiment of this invention and shown in FIGS. 22-26. It is to be noted, however, that the tube 371 must remain stationary with relation to the lateral motion of the winding head 346' so that it and the extended plunger 381 may be overwound by the last few turns of yarn. Since the tube 341 is secured to the moving winding head, this is accomplished, as shown in FIG. 35, by having cylinder 387 an hydraulic cylinder to retard motion of tube 374. Cylinder 387 is a slave cylinder activated by a master cylinder 439 fixed to frame 314. This master cylinder 439 is mounted to have its piston rod 440 contact any portion of the moving winding head 346 at the desired stage of the winding. Hydraulic cylinder 387 then overrides the air cylinder 376 as it forces the

fingers

375 and 382 together extending plunger 381 and compressing spring 390. When the wind is completed, switches 435 disengage the clutch and apply the brake of unit 323 to stop the drive of winding head 346'. At the same time, clutch 425' is disengaged and clutch activated pulley 421 is engaged to reverse the drive to

shaft

423 and 423 to return winding head 346' and the disks 429 to their original positions.

While winding head 346' is completing a winding on one side of an eye, winding head 346 is driven by motor 320 and controlled in an identical manner by control box 357 to complete a winding on the other side of an eye. Since each winding head 346' and 346 is controlled and driven separately, a tandem winding station 312 can make different winds of difi'erent kinds and lengths on each side of an eye. This may be required to Wind ferrules, special eyes, etc.

If a winding station is to make identical winds, all the elements shown in FIG. 31 mounted on or above frame 316 may be omitted. However, a pulley should be placed on shaft 322 to drive pulley 344 so motor 319 may drive both winding heads. Shaft 423', and gear 391, as shown in FIG. 36, would then advance both winding heads 346' and 346 by providing a rack gear (not shown) on guide rod 394 in place of flat surface 395' to be engaged by gear 391.
