(Cl. 242- 56) mandrel and are indexible through 180 on completion of the winding of successive condensers. of metallized dielectric are drawn from supply rolls to form a composite web which is advanced over a stationary roller and one of the guide rollers and is wound onto the mandrel, and after a predetermined length of'the web has been wound onto the mandrel to form the condenser, the guide rollers are indexed through 180 to position the web leading from the condenser in a predetermined relation to a Web cutting device, an adhesive applicator, and a web positioning and tucking device. Adhesive is applied to the outer surface of the condenser to prevent the unwinding thereof, and the web is cut to position the end of the web supply in the path of the web positioning element. On completion of the winding of the condenser, the arbor is axially reciprocated to eject the condenser, the web positioning element is actuated to move the end of the web supply against the mandrel and support the end of the web in the path of the tucking device which is actuated to wrap the end of the web around the mandrel to secure the end of the web supply thereto after which the mandrel is rotated to again wind a predetermined length of the web thereon as part of another cycle of operation.

Other objects and advantages of the invention will become apparent by reference to the following detailed description thereof and the accompanying drawings illustrating a preferred embodiment thereof, in which Fig. l is a diagrammatic side elevational View of the condenser winding apparatus;

Fig. 2 is a diagrammatic, vertical, cross-sectional view of the apparatus;

Fig. 3 is a cam chart showing the sequence of the operation of the apparatus;

Figs. 4-9 are enlarged diagrammatic views showing the condensers being wound on the mandrel of the apparatus and the elements cooperating therewith in a series of changed positions during a cycle of operation; and

Fig. 10 is in enlarged detailed sectional view showing the tucker element wrapping the end of the web around the mandrel.

Referring to the drawings the apparatus comprises a mandrel, arbor, or spindle 17 of rectangular cross-section on which the condenser 18 is to be Wound. The condenser may be formed from separate strips of dielectrio and metal foil interleaved and wound together, but

T he two strips is shown here as being formed from a pair of strips of metallized dielectric 19, e. strips of dielectric, on one face of which has been deposited a film of vaporized metal. The strips 19', Figs. 2 and 4, are drawn from a pair of supply rolls not shown.) and form a composite web which passes around a stationary guide roller 23 and one roller of a pair of web guide rollers 25 as the web is wound on the mandrel 17. The mandrel 17 is supported in a hollow shaft 27 (Fig. 1) for rotary and reciprocatory movement and is secured to one end of a sleeve 28 which telescopi'tigly engages and is splined to a shaft 29 for rotation therewith and for axial movement relative thereto. The shaft 29 is fixed to one'elernen't 32 of a clutch 33, the other element 34 of which is splined to a drive shaft 35. The drive shaft 35 is driven from a variable speed transmission unit 38, which in turn is driven from a motor 39. The clutch element 34 is shiftable on the shaft 35 to, connect or disconnect the drive between theshaft 35 and'the shaft 29 by a shifting lever 41 which is fulcrumed at 42 and actuated by a barrel cam 43 mounted onia cam shaft 44. The cam shaft 44 is driven through a pair of gears 45-46, the latter of which is fixed to a shaft 47. A gear 48 also fixed to the shaft 47, meshes with a gear 49 on a countershaft 50 which also has fixed thereto a gear 51 which in turn is driven from a gear 52 on the drive shaft 35. Thus, the starting and stopping of rotation of the mandrel 17 is effected by the actuation of the clutch 33 by the earn 43.

The mandrel 17 is adapted to be re'ciprocated to cause the ejection or release of the wound condenser as the mandrel is Withdrawn therefrom. The reciprocation of with the shaft 47 and driven therefrom the mandrel is accomplished by the operation of a pneumatic actuator which comprises a piston 53 r' eciprocable in an air cylinder 54 and having a piston rod 55 on which is fixed a shifter fork 56 which in turn engages a shifting collar 57 on the sleeve 2-8. The piston is spring actuated in one direction and air actuated in the opposite directionby compressed air admitted to the cylinder through a pipeline 58 under control of a valve 59. The valve 59 is actuated to and from open and closed positions to effect the reciprocation of the arbor by a cam 60 which is fixed to the cam shaft 61, coaxially aligned through a clutch 62. One element 63 of the clutch is fixed to the shaft 61 and the other element 64 of the clutch is splined to' the shaft 47 and is shiftable into and out of engagement with the element 63 by a lever 65 fulcrumed at 66 and actuated by the barrel cam 67 on the cam shaft {4- The guide rollers 25 are rotatably supported on shafts 68 which are secured at their ends to the ends of crossarms 69 and 70. The cross-arm 69 is rotatably supported by a stub shaft 71 journaled in a bearing 72 and the cross-arm is fixed to the hollow shaft 27 which is mounted in a bearing 73 for rotation and against axial movement. The cross-arms 69 and 70, connected together by the shafts 68, form a rectangular frame or turret 74 therewith which is rotatable about the axis of the arbor 17.

Mechanism is provided for indexing the rollers and theiframe 74 through 180 comprising a gear 76 which is fixed to the hollow shaft 27 and meshes with a gear secured to a shaft 78. The shaft 78 is suitably mounted for rotation and has fixed thereto a forth-station Geneva disc 79 which cooperates with and is intermittently act'u ated by a Geneva lever 80 carried by a shaft 81. The

I shaft 81 has fixed thereto an element 82 of a clutch 83,

the movable element 84 of which is splined to the shaft 50. The movable clutch element 84 is adapted to be shifted into and out of engagement with the element 82- by a lever 85 fulcrumed at 8 6 and actuated by a barrel cam 37 fixed" to the cam shaft 44.

After the winding of the web 19 onto the mandrel 17 has been startedand a predetermined length of the web has been wound thereon, the clutch 33 is: actuated to disengage the drive to the arbor 17 and the clutch 83 is actuated to cause the rotation of. the Geneva lever through one revolution and causethe turret 74 and the rollers 25 to be indexed through 180 to move the web 19 on the rollers 25 from the position shown in Fig. 4 to that shown in Fig. 5. The web 19 (Fig. 5) extending from the condenser 18 on the arbor 17 is now in condition to be severed and glued or otherwise adhered to the condenser and to accomplish this, a gluing device or adhesive applicator 90, and a cutter device 91 are provided (Figs. 2. and 6).

The gluing device comprises an elongated box or receptacle 92 for containing a supply of glue, adhesive, dielectric solvent, or the like, into which one end of a feed wick 93 is placed. The other portion of the wick 93 extends outwardly from the container 92 and is supported on a platform 94. .The glue receptacle is carried by a pair of irregularly shaped arms 95 which are fixed to ashaft 96 suitably journalled forrocking movement. An arm 97 fixed to the shaft 96 is pivotally connected to a link 93, which is connected to one end of a lever 99. Pivotally supported at 1th), the lever 99 has a cam follower 101 which engages a cam102 fixed to the cam shaft 61. The glue receptacle 92 is movable under control of the cam 102 and a spring 193 from a normal posiing to retract the web while permitting movement of the web in a forward direction.

The arms 132 and 133 are fixed to rock shafts 134 and 135, respectively, suitably supported for oscillating movement. One of the pair of arms 132 extends beyond the roller and is connected to one end of a link 136, the other end of which link 1336 is connected to a lever 137 pivotally connected for rocking movement about a fulcrum 138. In like manner one of the arms 133 extends beyond the rock shaft and is connected on one end of a link 139, which, at its other end is connected to a lever pivotally'supported on the fulcrum 138. The levers 137 and 140 have cam followers 141 and 142, respectively (Figs. 1 and 2), which engage cams 143 and 144 fixed to the cam shaft 61.' The cams 143 and 144 act to separate the gripper rollers 130 and 131 from the guide rolls 25 in timed relation to the actuation of the other elements, and springs and 146 serve to move the rollers 130 and 131, respectively, in the opposite direction against the rollers 25.

After the web 19 has been severed and the condenser has been completely wound, glued, and ejected from the apparatus and the mandrel returned to its operative posi tion shown in Fig. 2 to an operative position shown in t Fig. 6 where the end of the wick 93 engages the supply web 19 and the outer portion of the condenser 18 on the mandrel 17. While the gluing device is held in its operative position the cutter 91 is actuated to sever the web 19.

The cutter device 91 (Fig. 2) comprises a cutting blade 104 fixed to a pair of arms 105 which are secured to a shaft 106 suitably journalled for rocking movement. An arm 107 fixed to the shaft 106, is pivotally connected to a link 108 which is also pivotally connected to a lever 109. The lever 109 is pivotally supported at 110 and has a'cam follower 111 which engages a earn 112 fixed to the cam shaft 61. The cam 112 actuates the cutter 104 in one direction and a spring 113 (Fig. 2) serves to return the cutter in the opposite direction. In response tothe actuation of the cutter device 91 from its normal position shown in Fig. 2 to the position indicated in dotted lines in Fig. 6, the cutter blade 104 cooperates with one of a pair of cutter blades 114-114 mounted on the arms 69 and 70 of the turret'to sever the supply web 19 at a point in spaced relation to the mandrel 17 to form a loose end 115 of the condenser web 19 and a loose end 117 of the web supply. After the web 19 has been severed the mandrel 17 is rotated slowly to wind the end 115 of the web 19 onto the condenser while the wick 93 of the gluing device 90 is in engagement with the condenser. Thus, as the end 115 of the web 19 is wound onto the condenser adhesive is applied thereto and serves to adhere the end 115 of the web to the condenser.

tion, the lower gripper roll 13%) is separated from the turret guide roll 25 to release the lower end portion of the web 19 while the upper gripper roller 131 remains in engagement with the other guide roller 25 to clamp the web against it. The apparatus is now in a position to initiate the winding of another condenser and a mechanism is provided for wrapping the end of the ,web supply around the arbor to secure the web thereto.

' A web positioning element or pusher is mounted for movement to engage the loose end 117 of the web 19 ata point between the mandrel 17 and thelower guide roll 25 and move it into the pathof a web wrapping or tucking device 156, which picks 'up the end 117 of the web and tucks it around the mandrel to secure the end of the web to the mandrel, after which the mandrel is slowly rotated to begin the winding operation. The pusher element 155 is carried by a pair of arms 158 which are fixed to a rock shaft 159 suitably journalled for oscillation. The shaft 159 has fixed thereto an arm 160 (Fig. 2)

which is pivotally connected to a link 161 which in turn .is connected to one end of a lever 162 mounted for oscillating movement about a pivot 163. The lever 162 carries a follower 164, which engages a cam 165 on the cam shaft 61 for actuating the pusher 155 in one direction and a spring 166 serves to return the pusher.

When the strips of metallized dielectric are made from material which is sufficiently heavy or stiff, the pusher 155 in its forward position will support the free end 117 of the composite web 19 in the path of the tucker device 156 as shown inFig. 7. When thestrips of metallized During the cutting of the web 19 after a condenser has i been wound and during the ejection of the condenser it is desirable to hold the portion of the web extending between the guide rollers 25 against movement to prevent the displacement thereof or damage thereto. To accomplish this a pair of gripper rollers 130 and 131 are provided to grip'the web against the guide rollers 25. The gripper rollers 130 and 131 (Figs. 2, 4, 5, and 6) are rotatably supported on shafts 130a and 131a which are carried by pairs of lever arms 132 and 133, respectively, for rocking movement toward and away from the guide rolls 25. One way clutches 13Gb and 1311 mount the rollers 130 and 131 on the shafts 130i: and 131a, respectively, for rotation in one direction only as indi-. cated by the arrows in Figs. 4 and 5 whereby when the gripper rollers 130 and 131 are pressed against the rollers 25 they serve to hold the web 19 against movement tenddielectric, are used which are relatively light and thin so that they will not, by their own rigidity, be supported in the position shown in Fig. 7, jets of air from one or more air nozzles 170 are provided to aid in carrying the, free end 117 of the composite web 19 into the position shown in Fig.7. The flow of air through the nozzle 170 iscontrolled by a valve 171 actuated by the arm 160 near the end of its downward stroke. When the air jets are not required to supplement the action of the pusher blade 155, the supply of air to the nozzles may be manually shut oil. If desired the air jets may be used in lieu of the pusher element 155 to support the end of the web 19 in the position indicated in Fig. 77

The tucker device 156 comprises a thin plate 175 which has a flange 176 bent at right angles thereto. T he plate 175 is yieldably supported on one end of a plurality of flat leaf springs 177 which are secured at their other ends to a bar 179. The bar. 179 has a pair of arms 180 extending'therefrom, which are pivotally connected by pins 181 to a pairof levers 182 fixed to a rock-shaft 183. Springs 184 stressthe members 179 and 180 and the member 175 carried thereby for rotation in a counterclockwise direction about the pins 181, which movement is arrested by a pair of stop pins 185 on the levers 182. The arms 130 of the member 179 are spaced apart a distance suflicient to straddle the arms 69 and 70 of the turret 74 and the ends 187 of the arms 180 extend beyond the pivots 181 and are adapted to engage stationary stop elements 188 during the tucking operation as the tucker device 155 is moved from its normal position shown in Fig. 2 to its operative position shown in Fig. 9. The tucker 156 is actuated by mechanism including an arm 192 (Fig. 2) fixed to the shaft 183 and connected to a link 193, which is connected to a cam lever 194 oscillatable about a pivot 195 and having a follower 196 engageable with a cam 197 on the cam shaft 61. A spring 198 (Fig. 2) serves to return the tucker 156. After the pusher element 155 has been advanced to the position shown in Fig. 7 to direct the loose end 117 of the web 19 into the path of the members 175 and 176 of the tucker, the cam 197 serves to rock the shaft 183 and rotate the tucker device 156 in a counter-clockwise direction to cause the member 176 and the springs 177 to engage the free end 117 of the web 19 and carry it upwardly around the mandrel 17. When the tucker has advanced to the position shown in Fig. 8, the extension 187 of the arms 180 will engage stops 188 and as the levers 182 continue their turning movement in a counter-clockwise direction, the member 179 and the members 175, 176, and 177 carried thereby will be rotated in a clockwise direction about the pins 181 and the flange member 176 will be moved over and around the mandrel 17 and will serve to wrap a portion of the end 117 of the web around the mandrel and tuck a portion of the web between the mandrel and the portion of the web 19 extending between the mandrel 17 and the upper guide roller 25 to secure the loose end 117 of the supply web to the mandrel as indicated in Figs. 9 and 10. At this point the mandrel is actuated to rotate slowly to begin the winding of the condenser and after a few turns of the web have been wound on the mandrel the tucker device 156 is returned to its normal position. After the pusher 155 and the tucker device 156 have been retracted the rotation of the mandrel is shifted from low to high speed which continues until a predetermined length of the web 19 has been wound thereon after which the clutch 33 is actuated to disconnect the mandrel drive and stop the mandrel. The mandrel is driven at low or high speed from the variable speed transmission 38 which is shifted to and from high and low speeds by any suitable electrical actuating device 199 (Fig. 1) under control of a switch 238, which is actuated from one position to another by a cam 261 on the cam shaft 61. In each cycle of operation the barrel cam 43 actuates the clutch 33 and controls the starting and stopping of the rotation of the mandrel 17, the barrel cam 87 controls the actuation of the clutch 83 to eifect one revolution of the Geneva arm 80 and the indexing of the turret 84 and the guide rollers 25 through 180, and the barrel cam 67 controls the actuation of the clutch 62 and the rotation of the cam shaft 61 and the cams thereon through one revolution, and during the rotation of the cam shaft 61 the cams thereon control the shifting of the speed of rotation of the mandrel 17 to and from high and low, and the actuation of the adhesive applicator 90, the cutter device $1, the condenser ejector device 53, 54, the gripper rollers 13% and 131, the pusher element 155, and the tucker 155, in timed relation to each other. The sequence of operation of the various elements of the apparatus is indicated diagrammatically in the cam chart (Fig. 3).

To review the operation of the device, we shall assume that the web 19 has been wrapped around the mandrel 17 and the rotation of the mandrel has been shifted into high speed, and after a predetermined length of the web 19 has been wound on the mandrel (Fig. 4) it is stopped by the disengagement of the clutch 33, and rotation of the cam shaft 61 is started by the engagement of the clutch 62. The turret is indexed through 180 from the position shown in Fig. 4 to that shown in Fig. 5 in response to actuation of the clutch 83, after which gripper rollers 13% and 131 are actuated to grip the web 19 against the rollers 25, the adhesive applicator is actuated to engage the condenser 18 on the mandrel and the web extending therefrom to apply an adhesive thereto, and while the applicator 9b is held in engagement with the condenser, the web leadingfrom the condenser is severed by the actuation of the cutter device 91. The mandrel 17 is then started rotating at a slow speed to Wind up the loose end of the web onto the condenser and cause adhesive to be applied thereto as it is being wound to adhere the end of the web to the condenser after which the mandrel is stopped. The adhesive applicator 90 is then returned to its normal position and the mandrel 17 is retracted to cause the withdrawal of the mandrel from the condenser and the release and ejection of the condenser from the apparatus after which the mandrel is returned to its normal position. The lower gripper roller is separated from the lower guide roll 25 to free the end portion of the web 19 while the upper gripper roller 131 remains actuated to grip the web against the upper guide roller 25. The pusher element and the air jets are actuated to carry the free end of the web 19 against the mandrel 17 and into the path of the tucker device 156, which is then actuated to pick up the end portion of the web and wrap it around the mandrel, after which rotation of the mandrel is started at low speed to wind several turns of the web onto the mandrel and initiate the winding operation, the pusher 155 and the tucker 156 are returned to their normal inoperative positions and the rotation of the mandrel is shifted into high speed and continues at high speed until, as previously stated, a predetermined length of the web 19 has been wound thereon, at which time the mandrel is stopped and the sequence of operation is repeated.

It is to be understood that the above-described arrangements are simply illustrative of the application of the principles of this invention. Numerous other arrangements may be readily devised by those skilled in'the art which will embody the principles of the invention and fall within the spirit and scope thereof.
