Process for machine winding of toroidal cores

This invention relates to a method of machine winding of especially small toroidal cores with winding wire consisting of one or more There can be conductors for generating at least one winding provided with or without taps, the ends of which with the connection points of a winding Carrier plates are connected, the winding production being carried out automatically in a device containing several processing stages.

Wrapped toroidal cores, which are preferably made of magnetizable material, are used in today's circuit technology in very large numbers in electro-magnetic memories, in shift registers, in delay circuits, used as transformers or in other electrical assemblies.

These toroidal cores have a corresponding to the respective requirements or to provide several windings, which in turn can have taps if necessary. The winding ends or the ends of the taps lead to connection points which z, B, on a switching card

are ordered, which also act as a carrier for the wound Serves toroidal cores.

To generate the winding turns, the toroidal core is mostly toroidal are different winding methods and winding devices become known, which mostly use a hollow winding ring as a shuttle rotating around the toroidal core, which is divisible, or not circular

t is closed so that it encompasses the toroid in its core hole can be used. In the cavity of the wrapping ring for the Winding required amount of winding wire loaded. By the American In patent specification 3,010,505 a winding ring was known in which the winding wire is placed in a spiral shape into the cavity of the winding ring became. The German patent specification 829,014 also shows a winding ring consisting of a tube bent in the shape of a ring, in which the winding wire is used is embedded spirally. The winding ring is driven by rollers arranged on the circumference of the winding ring. Due to the spiral arrangement of the winding wire in the winding ring results in a relatively large cross-sectional diameter of the winding ring, so that this method at

. Toroidal cores with a small core hole is not applicable.

Through the German patent specification 1,070,294 a through for small Ring cores usable winding ring with an outside diameter of 0.6 mm known whose circumference is provided with a slot for the winding wire to pass through. Another winding process for also small toroidal cores in which the wire is threaded through the core hole with a machine-controlled needle is described in German patent 1.099. 642 described. Another wrapping technique where there is no rotating wrapping ring or a Threading needles were required by a publication in the IBM Technical Disclosure Bulletin Vol. 8, No. 3, August 1965, page 450. In this process, an approximately semicircular thin tube

clien, which has the shape of half a turn, in the core hole of the toroidal core. The winding wire is fed to this tube from a supply roll via a drive roll. The winding wire kicks in at the mouthpiece of the tube in the form of a helical spiral and loops around the toroidal core.

According to the known winding process, especially for toroidal cores in miniature dimensions, it is difficult to mass-produce these cheaply with them several windings or with windings that have taps. In many cases, the smaller toroidal cores are only partially wound by machine and the remaining windings are threaded by hand, including the Connections of the winding ends and the winding taps are made by Hand executed.

It is also known that not only a winding wire, but several winding wires lying next to each other in parallel can be used at the same time for various reasons, e.g. formation of several coiled windings, creation of windings with taps, Enlargement of the winding cross-section, achieving better flexibility of the winding material, etc.

In the case of series production, it is desirable that all of the products produced if possible, the same properties within a specified tolerance range exhibit. In the case of toroidal cores in which the space is very limited due to the core hole, this means that the turns are tight rest on the surface of the toroid that the individual turns do not cross or overlap and that a predetermined uniform distance between the adjacent ones wrapped around the toroidal core Turns.

The object of the invention is to provide a method for machine winding of Indicate toroidal cores with winding wire consisting of one or more conductors can exist. It should be guaranteed that the finished wound and connected toroidal cores have the desired properties within the tolerance range that the turns do not cross or superimpose and that there are equal = $ A gaps between the turns. Aside from that, that the machine production of the windings and their connection takes place automatically in successive interdependent steps.

According to the invention, this object is achieved in that in a winding device before winding the winding wire unwound from a supply roll via a take-off device, through feed rolls, one not yet operated wire cutting device and a movable wire guide piece is monitored and controlled by a measuring device that is loaded into a, the fixed toroidal core comprehensive winding ring by a measuring device a signal from the measuring device of the winding wire being held by the feed rollers the winding process is triggered by connecting the Drive motor and thus the rotation of the winding ring around the toroidal core and a rotation of the same takes place that the number of turns and the position of the rocker ring is determined by a counting device that by a Signal from the counting device via a control circuit the end of the winding process, the cutting of the winding wire and a return of the

* The device shown in principle in Fig. 1 is used for automatic Winding of toroidal cores or similar core shapes and for Separation of the conductor wires of the winding wire used for winding, which can consist of several individual conductors. This facility exists from a core winding device 10, which takes the from a supply roll 12 related winding wire 11 winds toroidally around a toroidal core 14. the Toroidal cores are fed from the core winding device 10 to a core supply device 15, which preferably consists of a vibrating conveyor which aligns the cores and which consists of a tube 16 on the aisle • has, through which the cores 14 of the core winding device 10 are fed. The ring supplied by the core feed tube 16

Cores 14 can either be manually operated on the core winder 10 or automatically filed.

After passing through the core winding device 10, the winding wire 11 um the toroidal core 14 was wound, the wound toroidal core 14 is either transported manually or automatically to the next processing station and deposited on a carrier plate 17. The carrier plate 17 is in each case on an arm 18 of a rotatable index disk 19 arranged. To secure the position of the toroidal core deposited on the carrier plate 17, it is held in place by a pin 20, which reaches through the opening in the ring crown 14. The pins 20 are from a vibrating pin conveyor 21 supplied through a tube 22, and either manually or automatically inserted into the opening of the toroidal cores.

By located on the fingers 18 of the rotatable index disk 19 Wire holder 23, the two ends of the winding wire 11 wound around the toroidal core 14 are fixed. The clamping of the winding wire in the Wire holder can be done either manually or automatically.

The carrier plates 17 are placed on the fingers 18 before the index disk 19 rotates into the position in which the toroidal cores 14 on the Carrier plate 17 are placed. The carrier plates 17 are supplied from a magazine 24 to the fingers 18 and are on this by means of Clamp held.

After the wound toroidal core 14 through a pin 20 on a carrier plate 17 is fixed, the index disk 19, which is shown in FIG. 1 is shown, rotated clockwise until the fingers 18 to

conductors or, the spreading of the ends of the around the toroidal core 14 coiled winding wire. In the connection station 25 are only the conductors from one end of the winding wire wound around the toroidal core 14 11 separated from each other while in a second connection station 26, the conductors of the other end of the winding wire 11 are separated. These two connection stations 25 and 26 are therefore necessary because one end of the winding wire 11 appears on the top and the other end of the winding wire on the underside of the ^ ingkernes 14 appears.

Each of the two connection stations 25, 26 has a device by the severed or singulated from the ends of the winding wire 11 Wires each at a specific connection point on the carrier plate 17, which can for example be a printed circuit card, are soldered on. The connection stations 25 and 26 thus contain Devices that separate the conductors of the winding wire 11 from one another and also firmly connect these isolated wires to a connection point assigned to them.

That between the wire separating device and the wire holder 23 lying piece of the winding wire 11 is not required, therefore a cutting station 27 is provided in which they are not required inside the wire holder 23 lying pieces of wire are removed.

By rotating the index disk 19, the fingers 18, which located in the second connection station 26, passed on to a test station 28. During this turning process, in which the fingers 18 of the second connection station 26 are led into the test station 28, happen the fingers 18 the cutting station 28, while the index disk 19 is not stopped, while the fingers 18 pass through the cutting station 27 move. The ones that are not required lead to the wire holder 23 Wire pieces are cut off during the turning process and

far away. After testing the wound toroidal core 14 in the test station 28 a further rotation of the index disk 19 »follows, whereby the completed toroidal core 14 arrives at the ejector 29. In this ejection station 29 the pin 20, the toroidal core 14 and the support plate 17 are removed if the test conditions have not been met in the test station 28. at If the test conditions are met, the ejection station 28 is not in action fingers 18 pass this station. The tested and approved Toroidal core 14 arrives after passing the eject ta ti on 29 to a Unloading station. This unloading station is in the area of the station in which Another carrier plate 17 from the carrier magazine 24 is placed on the arm 18 of the rotatable index disk 19 and fastened.

In Figs. 2 and 3, a standing bracket 31 is shown, which as Support for the rotatable supply roll 12 of the winding wire 11 is used. This supply roll 12 is driven by a take-off motor 32, the is also attached to the bracket 31. The connection of the take-off motor 32 causes the supply roll 12 to rotate and that the Winding wire 11 is unwound.

The winding wire 11 runs from the supply roll 12 to a roll 33, which he partially wraps around. This roller 33 is rotatably arranged at one end of a pivotable arm 34, while the other end of the arm 34 is rotatably attached to the bracket 31.

The winding wire 11 continues from the roll 33 through a sleeve 35, the core winding device 10. This sleeve 35 extends from a mounting block 36 attached to a standing frame 37 to Outside. The other end of the sleeve 35 is adjacent to two guide rollers 38 and 39 which are driven by a feed motor 40 through an intermediate gear (not shown). The sleeve 35 is with the guide rollers 39 and 38 aligned and the winding wire 11 runs between

009615/1184

FI 9-68,005

see the guide rollers 38 and 39, so that when they are driven a feed of the winding wire 11 takes place. The upper guide roller 39 is rotatable on the upper mounting block 36 and the lower guide roller 38 is rotatable mounted on the lower mounting block 42, which is attached to the machine frame 37. The feed motor that drives the guide rollers 40 is attached to the upper mounting block 36.

The winding wire 11 continues through the guide rollers 38, 39 a second sleeve 43 attached to the first mounting block 36 and a third mounting block 44 of the machine frame 37 of the core winding device 10 is attached. The second sleeve 43 leads the winding wire 11 to a passage 45 in the third mounting block 44 (see FIG. 4). This third mounting block 44 contains a cutting device with a punching knife 46 which, when moved down into the passage 45, the winding wire 11 separates. The punch knife 46 is normal to the top biased by a spring 47 and does not protrude into the passage 45.

The punch knife 46, which is designed as a punch, is through a to the l_, agerstift 48 * rotatable swing beam 48 actuated, one of which End on the top of the punch knife 46 is, and the other End with a solenoid 49 is in communication. When the Solenoids 49, the swing beam 48 is rotated by its armature, so that the punch knife 46 is moved down into the passage 43 and the winding wire 11 cuts off. Such a cutting of the winding wire happens when a toroidal core 14 is completely wound became.

The guide channel for the winding wire goes behind the cutting device 11 into a curved sleeve 50, which has one end at the third Mounting block 44 is attached. This curved sleeve 50 is mounted in the holder 51 (see Fig. 2, 5, 6), which is on the top of a movable Mounting block 52 is attached.

900885/1184

FI 9-68-005

The other end of the arcuate sleeve 50 is connected to a guide channel 53 of a movable wire guide piece 54 (see FIG. 8). This movable wire guide piece 54 is arranged displaceably within a bore of the movable mounting block 52. That in the guide channel 53 of the movable wire guide piece 54 leading end of the arcuate sleeve 50 is preselected in its length so that there is always a connection between the end of the arcuate sleeve 50 and the guide channel 53, even if the movable wire guide piece 54 through a Toggle lever 56 is moved downward (see Fig. 6). The lower end of the movable wire guide piece merges into a thin, cylindrical and needle-shaped hollow pin 57 through which the guide channel 53 also runs. The winding wire 11 consequently has a path which runs through the feed rollers 38, 39 through the arcuate sleeve 50 and through the guide channel 53 of the movable wire guide piece 54 with a hollow pin 57. A toggle lever 56 is connected to the movable Drahtfühxungsstück 54 by a pin 58, the piece on the movable wire guide 54 is secured, a slot 59 in the movable mounting block 52 penetrates and whose end \ n a slot 60 protrudes the toggle lever 56th

On the movable mounting block 52, the toggle lever 56 is through the Pin 61 rotatably mounted and its other end is rotatably connected to a rod 62 which leads to an armature of a solenoid 63, the is also attached to the movable mounting block 52. An excitement of the solenoid 63 causes the toggle lever 56 to rotate slightly and the movable wire guide piece 54 pushes down. Through this the needle-shaped hollow pin 57 of the movable wire guide piece 54 is also moved downwards and penetrates the opening of the toroidal core 14. The toroidal core 14 is held so that when the movable Wire guide piece 54 is in its basic position, slightly below the tip of the needle-shaped hollow pin 57.

FI 968 003

The toroidal core 14 is fixed in its position by a bracket that an upper fixed bracket 70 and a lower movable bracket 71 (Fig. 11). These two brackets 70 and 71 are yoke 72 worn. The yoke 72 is rotatably mounted in a bearing block 73, which is fixed to the vertical machine frame 37 of the core winding device 10 is connected.

The bearing block 73 contains a hollow shaft 75 ^r , which is mounted in an upper shoulder 74 and in a lower shoulder 75 of the yoke 72. A rod 76 extends through this hollow shaft 75, along with its central axis

the axis of rotation of the yoke 72 coincides. The axis of rotation of the yoke 72 is the longitudinal axis of the hollow shaft 75 *.

The lower end of the rod 76 is with the top of the L-shaped Slider 77 firmly connected (Fig. 11). The L-shaped slider 77 is slidable in the vertical direction and engages with a groove 78 in the yoke 72. The underside of the L-shaped slider 77 has a Pin 79 which is connected to the movable bracket 71.

If the pin 79 moves downwards, the movable clamp will: * 71 lifted from the upper clamp 70 and an insertion of the toroidal core 14 allows between the two brackets. By an upward movement of the pin 79 or the rod 76, the toroidal core 14 is in fixed in its position. When the toroidal core 14 is fixed in its position by the two brackets 70, 71, the hollow pin 57 of the movable Wire guide piece 54 penetrate the opening in the toroidal core 14. Furthermore, the arrangement is such that when the yoke 72 rotates about its axis, the toroidal core 14 also rotates about its axis and with it executes a relative movement to the winding wire 11 during the winding process.

FI 968 005

The upper end of the rod 76 extends over the upper lug 74 of the yoke 72 and is firmly connected to a transmission lever 80 which is rotatably mounted on the carrier 81 (see Fig. 2). On the At the other end of the transmission lever 80, a roller 82 is attached, which rests on a flat rotatable cam disk 83. This rotatable The cam disk 83 is arranged on a support plate 84, which in turn is fastened to the bearing block 73, on which the carrier 81 is also attached is mounted * When the cam 83 is in a certain direction rotates, this causes the movable bracket 71 to separate from the fixed one Bracket 70 moves downwardly, while rotation of cam 63 in the opposite direction moves upwardly movable clamp 71 causes the toroidal core 14 to be clamped between the two clamps 70, 71. The movable bracket 71 consists of a resilient, resilient material in order to avoid damage to the toroidal core 14. The cam disk 83 is driven by the motor 85.

A switch 87 attached to the support 81 has a switch arm 88 which of the. Transmission lever 80 is operated. The switch 87 is closed State when a toroidal core 14 is held by the two clamps 70, 71. When the transmission lever 80 by rotation the cam disk 83 is moved so that the ring core 14 is released by the two clamps 70, 71, then the switch opens 87. The switch 87 thus generates a signal to indicate whether the Brackets 70, 71 a toroidal core 14 is clamped or not.

From Fig. 5 it can be seen that in the movable block 52 a rotatable wrapping ring 90 is mounted. The wrapping ring 90 has the Form of a not completely closed circular ring, the two ends 91 and 92 of which is slightly larger than the gap in the movable one Mounting block 52, which is used to hold the toroidal core 14. The winding ring 90 is thus designed so that the toroidal core 14 between the two

909885/1104

FI 9-68-005

Ends 91 and 92 of the wrapping ring 90 can be arranged.

The wrapping ring 90 has a cavity 93 (see FIGS. 31 and 32) which extends through the entire wrapping ring 90 from one end 91 to the other end 92. This cavity serves to accommodate the required winding wire 11 in the winding ring 90 for a winding process. The cavity 93 in the winding ring 90 is designed as a groove which is covered by a circular ring 93 ¹ , whereby the closed cavity 93 is formed. The inner ring side of the winding ring 90 is provided with teeth 94 which mesh with the two drive pinions 95 and 96 (see FIGS. 5 and 10). These two drive pinions 95 and 96 are rotatably mounted in the movable mounting block 52.

From Fig. 10 it can be seen that the two drive pinions 95 and 96 driven by a motor 97 mounted on a mounting block 98 is mounted and · is firmly connected to the machine frame (see Fig. 9). A gear 99 mounted on the shaft of the motor 97 meshes with it Gear 100, which is firmly connected to the shaft 101, which is rotatable in the Machine frame. 37 and is stored in the mounting block 98. The wave 101 carries a gear wheel 102 on one side, which is coupled to the two gear wheels 103 and 104 and which is attached to the shafts 105 and 106 are. The shaft 105 is rotatably mounted in the movable mounting block 52 and is firmly connected to the drive pinion 95. While the wave 106, which is also rotatably mounted in the movable mounting block 96, with the drive pinion 96 is firmly connected. An excitation of the motor 97 thus causes a rotary movement of the winding ring 90.

A mounting plate 107 (see Figs. 2 and 5) is within the moveable Mounting block 52 attached to the wrapping ring 90 in the desired To hold position. This fastening plate 107 is provided on its circumference with a recess 108 adapted to the toroidal core 14.

From Fig. 10 it can be seen that a worm wheel on the shaft 101 110, which is coupled to the gear 111 (see Fig. 13). This gear 111 is located on the shaft 112 (see Fig. 11). the At its upper end, shaft 112 has a bevel gear 113 which is coupled to a bevel gear 114. The bevel gear 114 is also with a Bevel gear 115 coupled to the lower end of a shaft 116 of a magnetic coupling 117 is attached. This magnetic coupling 117 (see Fig. 11) has a shaft 118 on its upper side, which is connected to the yoke 72 by transmission members and can rotate the yoke 72. These Arrangement has the effect that whenever the magnetic coupling 117 is energized, that by the motor 97, which causes a rotation of the winding ring 90, a simultaneous rotation of the yoke 72 also takes place.

From Fig. 11 it can be seen that the upper end of the shaft 118 on the magnetic coupling 117 is equipped with a sprocket 119 into which the Drive chain 120 engages. This transmission chain 120 also wraps around a sprocket 121 connected to the upper shoulder 74 of the yoke 72. A tensioning wheel 122 holding the chain engaged is on the support plate 84 of the bearing block 73 attached. The shaft 118 on the top of the magnetic coupling 117 is freely rotatable when the magnetic coupling 117 is not aroused.

Whenever the magnetic coupling 117, which is attached to the support plate 84 is, is excited, the yoke 72 is about the axis of the Ho-hlwelle 75 » turn. As a result, the toroidal core 14, which is supported by the yoke 72, also rotates. The two rotational speeds of the toroidal core 14 about its vertical axis and that of the winding ring 90 are in a certain relationship to one another. The desired relation between the Wrapping of the toroidal core 14 by the winding wire 11 and the simultaneous fe Further rotation of the toroidal core 14 prevents the turns of the toroidal core 14 from crossing, superimposing or overlapping. The yoke 72 is rotated around the axis of the cylinder part 75 * as soon as the magnet

clutch 117 and the motor 97 are switched on. The rotation of the the core 14 carried by the yoke 72 is with the rotation of the winding ring 90 selectable, whereby the desired pitch of the windings around the core 14 is achieved and prevents the windings from crossing or overlapping will.

To count the number of revolutions of the wrapping ring 90 or the motor 97, a disk 124 (see FIG. 9) rotating therewith is attached to the worm wheel 110. This disc 124 has an opening which works with a photocell and a light source that are attached in the recesses 125 and 126 of a bracket 127, which rests on the bearing block 98.

The disc 124 rotates between the recesses 125 and 126 so that that with each rotation of the disk 124 and the screws 110 a light beam falls through the opening in the disk 124, which affects the photocell and which then supplies a counting signal. Since the worm wheel 110 performs 12 revolutions for each revolution of the winding ring 90 30 each of a revolution of the wrapping ring 90 are counted. A predetermined count signal is used to determine when the motor 97 has stopped must become.

After the winding wire 11 is inserted into the cavity 93 of the winding ring 90 he must during most of the revolution of the Wrapping ring 90 are held. During each revolution of the winding ring 90, only a small part of the total length of the winding wire is allowed to the. Wrapping ring 90 can be pulled out. The winding wire 11 is held between the feed rollers 38, 39 after this does not can be driven more by the feed motor 40. .

At the end 92 of the outer surface of the winding ring 90 is a leaf spring 128 (see Fig. 14) attached. Once the surface of the mounting block

52 at the free end of the leaf spring 128 rests so that this against the Winding wire 11 in cavity 93 through an opening in winding ring 90 presses, the winding wire 11 is clamped on the winding ring 90.

At a certain angle, offset from the first leaf spring 128, has the winding ring 90 has a second leaf spring 129 on its outer surface. This second leaf spring 129 holds through an opening in the winding ring 90 the Winding wire 11 together with the first leaf spring 128 in the winding ring 90 so that it cannot slip.

The second leaf spring 129 runs in a guide groove, not shown in the storage block 52 during a period in which the first Leaf spring 128 does not rest on the surface of the bearing block 52. Just During this short interval, a piece of the winding wire 11 can be removed from the cavity of the winding ring 90, around the winding wire 11 to continue to wind around the toroidal core 14. During the remainder of one revolution of the wrapping ring 90, no further piece of wire x 11 can be removed from the wrapping ring 90.

The winding of the winding wire 11 around the toroidal core 14 is shown in FIGS. 15 to 19 shown schematically. As shown in FIG. 15, the winding wire H is moved with the aid of the movable wire guide piece 54 inserted into the cavity 93 of the winding ring 90. As soon as the winding ring 90 begins to rotate, the first leaf spring 128 clamps the The winding wire 11 is fixed in the winding ring 30, while the other end of the winding wire 11 is held in place by the feed rollers 38 and 39. the Clockwise rotation of wrap ring 90 from that shown in FIG Position in the position shown in Fig. 17 causes formation a loose loop of the winding wire 11 around the toroidal core 14 while this rotates at the same time, since the yoke 72 also rotates due to the excitation of the magnetic coupling 117.

When the winding ring 90 has rotated into the position shown in FIG. 18, the winding wire 11 has wrapped a complete tight loop around the toroidal core 14, but this is not yet firmly wound. When the winding ring 90 moves from the position shown in FIG. 17 to the position shown in FIG. 18, a piece of the winding wire 11 is released, since the first leaf spring 128 does not lie against the surface of the bearing block 52 and the winding wire 11 is in the winding ring 90 presses and since on the other hand the second leaf spring 129 runs with its free end in a groove in the bearing block 52 so that the winding wire 11 in the Wickelh ring 90 is not clamped.

If the wrapping ring 90 continues to rotate clockwise, the Winding wire 11 tightly wound around toroidal core 14. This tightening the Winding loop occurs when wrap ring 90 is in position has rotated, which goes slightly beyond the position shown in FIG. At this time, the winding wire 11 forms a straight line between the end 92 of the winding ring 90 and the toroidal core 14, so that the winding loop, is wrapped tightly.

This winding of the winding wire 11 around the toroidal core 14 is continued, until the desired number of turns or revolutions of the winding ring 90 is reached, which is indicated by the counter. Further rotation of the winding ring 90 is then stopped in that the motor 97 is stopped, whereby the yoke 72 is no longer either is rotated further and the toroidal core 14 also stops.

On the other hand, however, the magnetic coupling 117 remains excited in order to prevent the yoke 72 from being pulled back into its initial position by a return spring, which the yoke 72 rests continuously on the bearing plate 84 of the bearing block 73 against the rotational force of the motor 97. The housing 130 has a certain distance from the bearing plate 84 due to the spacer bolts 131.

When the motor 97 through a circuit, not shown, the signals of the counter with the photocell in the recess 125 due to the rotation of disc 124 is turned off, a solenoid 132 (see Fig. 13) is energized. The energized solenoid 132 overcomes the force of a spring 133 immobile a latch 134 around a pivot pin 135 counterclockwise as the solenoid 132 is energized withdraws its anchor. The spring 13 3 pushes the bolt 134 clockwise around the bearing pin 135, which the bolt 134 on a Bearing block 135. The bearing block 135 is attached to the vertical bracket 37 and also supports the solenoid 132.

At one end of the bolt 134 a roller 137 is attached, which in a Notch 138 in an annular plate 139 engages. The plate 139 rotates with the shaft 101 ,. on which it is attached. According to the Representation in Fig. 10 is an approach to the annular plate 139 Receiving the gear 100 formed, which in this way with the shaft 101 is connected.

When the motor 97 is turned off, the roller 137 falls into the notch 138 in the annular plate 139 if the solenoid 132 has been energized. The solenoid 132 is energized by the control circuit after this a signal from the counter means for stopping the motor 97 received Has. When the roller 137 has collapsed into the notch 138, is the motor 97 is locked and the wrapping ring 90 is in an initial position.

In this starting position, a sensing solenoid 140 (see FIGS. 2, 4) excited. As a result, a lever arm 141, which is rotatably mounted on the housing 152 from a pin 142, is rotated in the counterclockwise direction. With this rotation of the lever arm 141, a sensing pin 143 is moved upward. When the wrapping ring 90 is in its starting position, the sensing pin 143 enters a notch 144 located in the winding ring 90

(see FIGS. 14 and 32), whereby a projection 145 extending downward from the lever arm 141 comes out of engagement with a roller 146 (see FIG. 2) which is fastened to a switching arm 147 of a switch 148. As a result, the Switch 148 and sends a control signal which indicates that the wrapping ring 90 is in its home position.

If the wrapping ring 90 is not in its starting position, it switches the control circuit does not turn off the solenoid 132. As a result, the Roller 137 moved out of notch 138 in annular plate 139 and the motor 97 turned off for one revolution. Through the squat Gear (Fig. 10) d and the Zahnradanordnua-; on the wrapping ring 90 this leads to a rotary movement of the winding ring 90 by 1/12 Revolution = 30.

Then the solenoid 132 is switched off, the roller 137 in e'ine again Notch 138 of circular plate 139 set and the wrapping ring, 90

Thereafter, the solenoid 140 is energized again, which is a predetermined one Is turned off for a long time after it is energized by the control circuit If the wrapping ring 90 is now in its starting position.

the feeler pin 143 re-enters the notch 144 and the process continues as described above. If necessary, this cycle is repeated until the wire guide piece 90 is in its starting position.

When the switch 148 indicates by its signal that the wrapping ring is in its home position, a solenoid 49 (see Fig. 4) is energized by the control circuit, so that the punch knife 46 the winding wire 11 cuts off. The control circuit then gives a signal to rotate the cam 83, removing the lower bracket 71 from the upper bracket 70 is moved away to the u ^ th. The ring 14 is then easily out of the

Removable bracket. In the event of an automatic removal of the toroidal core from FIG. ¹ from the holder, the control circuit must ensure that the toroidal core 14 is gripped before the cam disk 83 is rotated.

After the cam disk 83 the bracket ■ 71 from the bracket 70 so has removed that the two clamps no longer hold the toroidal core 14, the magnetic coupling 117 is switched off in response to a signal from switch 87, which indicates that bracket 71 has been removed from bracket 70 was moved away. Now the return spring in the housing 130 pulls quickly the yoke 72. back to its original position, so that it is ready for another winding cycle. With an automatic removal of the Toroidal core 14 can, of course, the magnetic coupling 117 through the control circuit are only switched off when it has received a signal which indicates that the discharge mechanism is removing the toroidal core 14 from the Has removed clips 70 and 71. '

When operating this core-winding device 10, the toroidal core must first 14 can be placed between the brackets 70 and 71 by the cam disc 83 is rotated so that the clamp 71 due to its spring force moves upwards and the toroidal core 14 between the upper clamp 70 and the tmtere clamp 71 clamped. In this position of the toroidal core 14, the winding wire 11 is switched on by switching on the feed motor 40 from. the ¥ ®rratsspule IE fed, while the feed rollers 38 and 39 feed the winding wire 11, the arm 34 rotates due to it of the rollers 38 and 39 exerted on the roller 233 by the feeder Kraft and bib 11 is drawn in.

When the roller 33 has advanced so far that the arm 34 actuated the switch 149 shown in FIG. 2, which is on the holder 31 is attached, then the switch 149 causes the switching on of the supply bottle motor 32, whereby the supply reel 12 is rotated so that

a predetermined amount of the winding wire 11 is unwound from her. The amount of winding wire 1.1 released by the supply reel 12 is greater than that required for a single pass to load the wrap ring 90 Amount so that the supply reel motor 32 does not turn on every cycle of the feed motor 40 switching cycle. Since the tension spring 150 holds the arm 34 continuously in the position shown in FIG returned to the position shown in Fig. 2, whereby the switch 149 opened again and with its signal of the control circuit ™ indicates that the supply spool motor 32 must be stopped.

When the control circuit is indicated by the switch 87 with a signal becomes that the toroidal core 14 is held between the clamps 70 and 71, the control circuit switches the feed roller motor 40 and at the same time the solenoid 63 on. Characterized the movable wire guide piece 54 is moved down so that the needle-shaped hollow pin 57 on lower end with that of the opening of the cavity 93 in the winding sr ing 90 enters into connection, so that the winding wire 11 in the winding ring 90 can be introduced.

Ψ The feed motor 40 has on its shaft one with this shaft

rotating perforated disk of a measuring device in which there are several openings arranged at the same angular distance. A photoelectric cell and a light source are mounted on the bearing block 36 so as to cooperate with the openings in the perforated disk such that the photocell each time outputs a signal to the control circuit and counts the rotation of the feed motor 40 when one of the openings, the light path between photocell and light source happened. When the control circuit has received a predetermined number of signals from the photocell indicating that a predetermined amount of winding wire 12 has been supplied to winding ring 90, supply motor 40 is stopped. Thereafter, the control circuit turns off the solenoid 63 ,,

so that the movable wire guide piece 54 by a shown in FIG Spring 152 is withdrawn, one end of which with the holder 51 on the bearing block 52 and the other end with the toggle lever 56 connected is.

The magnetic coupling 117 and the motor 97 are then switched on. The time relationships between switching on the cam disk 83, the feed roller motor 40, the motor 97, and the magnetic clutch 117 are shown in the diagram of FIG. When the magnetic coupling 117 and motor 97 are switched on, the yoke 72 around the axis of the cylinder part 75 * and the rod 76 at the same time as the wrapping ring 90 turned. As a result, the winding wire 11 is wound around the toroidal core 14, as is shown schematically in FIGS. 15 to 19.

After the wrapping ring 90 has rotated as predetermined, what through the counter is determined by the control circuit of the Motor 97 turned off and then the solenoid 132 turned on. As a result, the motor 97 and the wrapping ring 90 are against one another Rotation secured by bolt 134. Then the starting position will be ^ - solenoid 140 energized and the sensing pin 143 determines whether the wrap ring 90 is in its home position or not. According to the illustration In the timing diagram (FIG. 20), the solenoid 140 is energized immediately after the motor 97 is switched off. As already mentioned, however, the wrapping ring 90 must be in its starting position before the punch knife 46 can be operated to cut the winding wire 11. If the wrapping ring 90 is not in its starting position, the motor 97 is allowed to extend one revolution (1/12 of a revolution of the wrapping ring 90) until the sensing pin can engage in the notch 144 and the wrapping ring 90 is in its starting position.

When the signal from switch 148 indicates that the wrapping ring 90 is in its starting position, the solenoid 49 (see Fig.

909885/1184

FI 9-68-005

4) excited and thereby causes the winding wire 11 from the punch knife 46 is cut off. The activation of the solenoid 49 is shown in the diagram 20 also shown.

Then the motor 85 is used to drive the cam disk 8ί of of the control circuit turned on so that it the lower bracket 71 of the upper clamp 70 moved away so that the toroidal core 14 can be removed from the core winding device 10. With automatic ^ Transport of the toroidal core 14 must ensure that the unloading mechanism grips the toroidal core 14 before the motor 85 is switched on. After the cam 83 driven by the motor 85 one revolution has carried out, a signal is provided by switch 87, which indicates that the bracket 71 is now in one of the bracket 70 removed Position is so that the toroidal core 14 is no longer wedged between the brackets 70, 71. When this signal from the control circuit is received, this switches off the magnetic coupling 117, so that the return spring in the housing 130 quickly returns the yoke 72 to an initial position withdraws, whereupon a new winding cycle is started after a further toroidal core 14 has been inserted between the brackets 70 and 71 in advance.

In Fig. 21 one of the connection stations 25 and 26 is shown in which the Ends of the winding wire 11 of the winding are separated from one another. The connection stations consist of a base plate 160 with arranged thereon Bearing blocks 161, 162 and 163. A continuously running one Motor 164 is mounted on the bearing block 161 and is also through a bracket 165 held (see Fig. 22).

By actuating a clutch, one in the bearing blocks 161 and 162 rotatably mounted shaft 167 by a continuously running one Motor 164 rotated 360 once. On this wave 167 are the Noclaai-

discs 168, 169 and 170 arranged. The cam 168 controls the movement of a guide device 171 which controls the cam 169 the movement of a wire holder 172 and the cam 170 controls the movement of a wire spreader 173.

On one end of the shaft 167 sits a pulley 174 on which one also via a pulley 176 on shaft 177 of motor 164 running toothed belt 175 runs. The pulley 174 is with the shaft 167 only connected when the clutch is actuated. Thus it rotates continuously running pulley 174 drives shaft 167 every time the clutch is actuated.

The coupling comprises a disc 178 fixedly mounted on the shaft 167, on which a pivoting pawl 179 (see Fig. 22) is mounted so that it engages a ratchet wheel 180 which is fixed to the pulley 174 is attached and rotates with this. As soon as the pawl 179 engages the continuously rotating ratchet wheel 180, the Shaft 167 rotated.

The pawl 179 turns around a pin 181 seated on the disk 178 continuously rotated counterclockwise by a spring 182 (Fig. 22). The spring 182 acts between part of the pawl 179 and one Part 183 which is attached to the disk 178. The pawl 179 lies with a part 185 on a pivotably attached stop 184 which holds the pawl in the position shown in FIG the ratchet wheel 180 can come up. The stop piece 184 can be pivot an axis 186 and is driven by a spring, not shown held at the solenoid 188 in the position shown in FIG.

When the solenoid 188, which is mounted on the bearing block 161, is energized, its armature lifts the stop '184 over a connecting lever 187 to the top, so that the Xnschlagstüek 184 against

909885/1184

FI 9-68-005

rotates clockwise about axis 186 so that it is no longer on the part 185 of the pawl 179 rests. Thus, the spring 182 can bring the pawl into engagement with a tooth of the ratchet wheel 180, whereupon the Shaft 167 rotates.

If the stop piece 184 as shown in FIG. 22 by the Excitation of solenoid 188 is pivoted counterclockwise, engages a pin 189 on the stop piece 184 in a locking lever 190, which is also pivotably attached about the axis 186 that the locking lever 190 is raised against the force of a spring 191, which the pawl 179 permanently forces it into the position shown in FIG. Because the latch lever 190 rests against the stop piece 184 via the pin 189, the spring 191 also keeps the stop piece 184 permanently in the position shown in FIG. Thus, by energizing the solenoid 188, not only the stopper 184 but also the locking lever 190 is raised. According to the illustration in FIG. 22, the locking lever 190 rests on a nose part 183, whereby the part 185 of the pawl 179 and the nose part 183 between the Stop piece 184 and the locking lever 190 are held.

Shortly after the rotation of the shaft 167 due to the energization of the solenoid 188 has started, the stop piece 184 and the locking lever return 190 back into the position shown in FIG. When the wave 167 ' has completed about 360 of its rotation, part 185 of the Pawl 179 in the locking lever 190 and rotates it, as shown in FIG. 22, counterclockwise about the axis 186 against the force a spring 191. When the part 185 of the pawl 179 on the stop 184 rests, the pawl 179 is brought out of engagement with the ratchet wheel 180 of the shaft 167, so that the shaft 167 stops. The latch lever 190 falls behind the nose piece 183 and prevents any movement of the shaft 167 in the opposite direction by bouncing back from the stop piece 184.

When the shaft 167 begins to rotate, the cam journals 192 and 193 of the cam disks 168 and 169 on the corresponding high points of the cam disks, which have side slots, while the cam pin 194 of the cam disk 170 is on the lower part of the cam slot lies. The cam journals 192 and 193, however, are shown in their deep position in FIG and 193 to show associated mechanism.

The cam pin 193 is connected to a slide I96 via a connecting rod 195 guided in the bearing block 162. The slide 196 carries a Rotary adjuster 197 (see Fig. 28). This wire adjuster 197 can be placed on the slide I96 by means of a pin 198 (see Fig. 21) pivot between the downwardly extending parts of the arms 199 and 200 of the device 197 and a downwardly extending part of the Slide 196 is located.

The front ends of the arms 199 and 200 by a cover plate 201 together tied together. The lugs 202 and 203 are arranged between the front sides of the arms 199 and 200 and the cover plate 201 as it is shown in FIG. A bow spring 204 (see FIGS. 26 to 28) pushes the two approaches 202 and 203, which can be swiveled on the arms 199 and " are attached apart. As shown in FIG. 27, a first claw 205 located on extension 202 by means of a bow spring 204 at a certain distance from a second attached to the extension 203 Claw 206 held.

As shown in FIG. 26, the first claw 205 has on its lower one End an L-shaped approach on inn in contrast to the flat bottom edge of the Claw 206. In the open position shown in Fig. 27, the lower edges are the claws 205 and 206, which take up the winding wire 11, far enough apart, to also accommodate the ends of the winding if they are not in the right position.

Docket FI 968 005

When the slide 196 moves downward, the first pawl 205 contacts first the winding wire 11, whereby this via the bow spring 204 a Moment exerts on both claws 205 and 206. The two claws 205 and 205 close at the same time and direct the winding wire 11 with respect to them • middle or correct lateral position. This becomes a point of convergence created for the winding wire 11 after the individual conductors in Winding wire 11 were spread.

When the claws 205 and 206 are closed, they have a rectangular shape Depression that is just as large as the profile of the winding wireJ. 1. The claws 206 and 205 are in their movement in relation to each other are limited by the lugs 202 and 203 which cooperate with the lower surfaces of the arms 199 and 200, respectively (Fig. 26).

The claws 205 and 206 attack on the side of the ring core 14 so that they the coming on top of the toroidal core 14 end of the winding wire 11 of the winding in the horizontal plane of the top of the carrier plate Press 17. When the connection station for cutting the winding wire 11 which starts from the top of the toroidal core 14 is used is, so the claws 205 and 206 must follow the winding wire to move down to the level of the carrier plate 17,

The wire adjuster 197 becomes permanent relative to the slider 196 counterclockwise about the axis of the pin 198 by a spring 207 pulled (Fig. 21). The spring 207 acts between a part of the slide 196 and a connecting part 208, which the lower ends of the Arms 199 and 200 connects to one another. One from the connector 208 of the wire adjuster 197 carried screw 209 is in a widened opening 210 arranged in the slide 196. This opening 210 limited that by the spring. 207 torque applied to the wire adjuster 197, about the axis of the pin 198, since the head of the

Docket FI 968 005 9 0 9 8 8 5/1184

Screw 209 protrudes into opening 210.

This arrangement ensures that the claws 205 and 206 hold the winding wire 11 touched and moved into the surface plane of the carrier plate 17, before the legs 211, which are parallel, at a certain distance are mutually downwardly extending extensions of a part 212 which is carried on the end of the slide 196 and on this by screws is attached, take the winding wire 11. The legs 211 grip the winding wire 11 and hold it in a horizontal plane when the wire spreader 173 is moved upwards in order to separate the individual conductors of the winding wire 11 from one another.

So when the spool 196 moves down because of the cam pin 193 passes from the raised to the lower part of the cam, the claws 205 and 206 first grip the winding wire 11 and form a point of convergence for the individual conductors of the winding wire 11 when they are apart be separated. Then the legs 211 grip the winding wire to keep it in a horizontal plane when the wire spreader 173 is moved upwards.

As shown in FIGS. 21 and 24, the wire spreader 17 is 3 Fixedly mounted on the upper end of a plunger 215 which is slidably mounted between two guide rails 216 and 217 of the bearing block 163 is. The lower end of the plunger 215 is connected to the cam pin 194. The ram 215 thus moves between the guide rails 216 and 217, the bearing block 163 and a cover 217a up and down and moved thereby the wire spreader 173 corresponding to the position of the cam pin 194 in the column of the cam disk 170. The cover 217a has a Opening 217b (see FIG. 24) for receiving the cam pin 194.

The wire spreader includes a knife block 218 with three conical separation dockets FI 968 005 9 09 885/11 8 4

knives 219, 220 and 221, which are permanently mounted on the wire spreader. the Sharp cutting edges of the cutting knives 219, 220, 221 penetrate the Adhesive material with which the conductors of the winding wire 11 are connected to one another when the wire spreader 173 is due to the rotation of the Cam 170 moved upwards. The number of cutting knives used 219, 220, 221) depends on the number of conductors of the winding wire 11 from. B. in a winding wire 11 which contains four individual conductors, three cutting blades 219 to 221 are used.

^ The sharp edge of the separating knife 219 separates the adhesive that separates the

outer conductor on one side with the adjacent inner conductor of the Winding wire 11 connects, while the sharp edge of the severing knife 221 cuts the adhesive material that separates the outer conductor on the other side connects to the adjacent inner conductor. The sharp tip of the severing knife 220 separates the adhesive that holds the two inner conductors connects with each other. Thus, the three cutting knives 219 to 221 separate the four parallel conductors of the angle wire 11 from each other. The separation takes place essentially simultaneously in that the sharp tips of the Separating knives 219 to 221 are arranged in the same horizontal plane (FIGS. 24 and 33).

The knife block 218 carries two guide pieces 222 and 223, one larger Have depth than the knife block 218. The guide piece 222 is arranged outside next to the cutting knife 219, while the guide piece 223 is located outside next to the cutting knife 221. This moves the outer conductor, that of the adjacent inner conductor of the winding wire 11 is separated by the separating knife 219, after this separation between the separating knife 219 and the guide piece 222 along. Of the other outer conductor of the four-core winding wire 11 moves to the separation between the cutting knife 221 and the guide piece 223 along.

To ensure that the inner conductors of the winding wire 11 from each other be separated, a length running in the longitudinal direction must be the same of the winding wire 11 are provided between a convergence device, which by the beidai claws 205, 206 and the wire holder of the Clamping device 2 3 is given. By routing the outer conductors as described above, they are separated from the inner conductors of the winding wire separated. Thus, the wire holder 23 maintains a voltage of the outer conductors, upright even after they have been separated by the separating knives 219 and 221.

To make the inner conductor of the winding wire 11 just as long that the wire holder 2 3 can tension it, a wedge 224 is used (see Fig. 33). The upper end of the Wedge 224 is triangular and runs in at the tip of the severing knife 220 a first point 225 together. When the sharp tip of the severing knife 220 penetrates the adhesive that is the inner conductors of the winding wire 11 connects with each other, the tip of the wedge 224 shortly thereafter also moves between the inner veins. The tip of the wedge 224 is beveled downward from the plane of the separating knives 219 to 221 to a second point 226. In addition, the two sides are 227 and 228 of the wedge 224 beveled so that the inner conductors are deflected outwardly into the same plane as the severed portions of the outer conductors. Thus, the wedge 224 separates the inner conductors from one another and also keeps them under the same tension and in the same plane of direction out, like the outer conductors, so that they have the same effective length.

If the adhesive connecting the conductors consists of a thermoformable adhesive Material (such as, for example, a thermoplastic resin), may possibly a hot air nozzle 229 can be attached to blow a stream of hot air between the jaws 205, 206 and the legs 211.

One end of a coil compression spring 233 lies in a recess of the Base of the U-shaped bearing piece 2 30, the other end in a recess in the slide piece 2 31, accordingly the compression spring 2 33 presses the slide piece 231 continuously to the right (Fig. 29). The deflection of the slider 231 by the compression spring 233 is limited by a stop plate 2 34, which is attached to the leg ends of the U-shaped bearing piece 230.

The stop plate 234 has a bore 235 for receiving a plunger 236 which extends from the slider 231. The plunger 236 is arranged displaceably in the bore 235 and protrudes beyond the stop plate 234 and enables the slider 231 to be pushed to the left against the force of the compression spring 233 (see FIG. 29). The slider 231 is shown in FIG. 29 in a central position only for the purpose of heating.

243 is set in the flange 241 of the socket 237 so that the WijÄkeldraht 11 extends over it. The winding wire 11 is in the V-shaped notch 24 3 clamped by a V-shaped cutting edge 244 of a displaceable clamping piece 245. The V-shaped cutting edge 244 is made by a tension coil spring 246 continuously pulled into the notch 243, which surrounds a threaded bolt 247 at the lower end of the clamping piece 245 and through a Nut 248 is held. The threaded bolt 247 is part of the clamping piece 245.

The lower end of the bore 238 \ r_ of the sleeve 237 has guides into which a lug 249 of the clamp fits 245th This ensures that the V-shaped cutting edge 244 on the clamping piece 245 is always correctly aligned with the V-shaped notch 243 of the upper flange 241 of the socket 237.

Since the compression spring 233 always keeps the slider 231 away from the toroidal core 14, the winding wire 11 is always kept under tension by the compression spring 233. In addition, the winding wire 11 is clamped in this position and held to the desired horizontal position during the spreading of the head of the Wijükeldraht.

As mentioned earlier, the cam 168 controls the soldering device 171. The cam disk 178 is connected via its cam pin 17 2 to a rod 250 (see FIG. 21), which is slidable in the bearing block 162 is arranged.

In the connection station shown in Fig. Zl, in which the head of the Winding wire 11 come over the top of the toroidal core 14 and are separated, the motor 164 runs and thus also the pulley 174 continuous. If in a cycle of operation at the connection station the conductors of the winding wire 11 are to be separated from one another and soldered to the connection points of a carrier plate 17, that is Solenoid 188 actuated when one of the ends of the winding wire 11 in the Wire adjustment device 197 and in wire spreader 173 is located. The control the index plate 19 and the solenoid 188 take place via a control circuit. The excitation of the solenoid 188 results in the actuation of the clutch via the pawl 179 (see Fig. 22) which is in the ratchet wheel is incident on pulley 174 causing shaft 167 to rotate begins.

On the first rotation of shaft 167, the cam pin of cam 169 moves from the top of the slot in the cam 169 down and moves the slide 196 also down. When the slider 196 begins to move downward, touch the two claws 205 and 206 the winding wire 11, which comes over the top of the toroidal core 14. With the continuing downward movement of the slide 196 also the winding wire 11 is moved downwards, whereby the two claws 205, 206, which hold the winding wire 11, clamp it between them and after the separation of the conductor of the winding wire 11 form the point of convergence for the individual conductors.

After the two claws 205 and 206 put the winding wire between them have jammed, this is caused by the downward movement of the claws 205 and 206 pushed down along the outer surface of the toroidal core 14 until the two closed claws 205, 206 on the carrier plate 17 rest. Now they can't move any further, that

However, slide 196 runs relative to wire setting device 197 nO: h · · further down. As a result, the punches 211 grip the winding wire 11 after the two claws 205 and 206 rest on the carrier plate 17.

While the winding wire 11 between the wire holder 2 3 and the Claws 205 and 206 are held, the sockets 211 hold the winding wire 11 in its horizontal plane when the wire spreader 173 comes into contact with the winding wire 11 between the punch 211. If the Stamp 211 press the winding wire onto the carrier plate 17, the cam pin 193 has the lower part of the slot of the cam disk 169 achieved.

In this position of the cam pin 193, the surface of the begins To increase the cam slot in the cam disk 170 and the wire spreader 173 to lift over the cam 194 and the rod 215.

This moves up until its cutting knife 219 to 221 the ladder of the winding wire 11 separate material sticking together. The upward movement of wire spreader 173 continues until wedge 224 is in contact with the internal conductors of the winding wire 11. At this point the cam post 194 has the high part of the cam slot reached in the cam disk 170, continues on this part and holds the wire spreader 173 in its highest position. .

At the same time, the cam pin 192 begins in the slot of the. , Cam disk 168 to fall from the high to the low part, - 'so that the soldering electrode 258 in contact with the severed conductors of the winding wire 11 comes and this to the connection points of the carrier 17 soldered on.

After the cam pin 192 the low part in the slot of the cam plate 168 has reached, at the same time the cam pin 193 returns from

low back to the high part so that the soldering electrode 258 is raised and is returned to the starting position, runs at the same time the cam pin 19 3 from the low to the high part, so that the wire holder 192 is returned to the starting position and the cam pin I94 runs from the high to the low part, which makes the wire spreader 173 is returned to its lowest position. These movements take place at the same time and in the inevitable order, so that the Electrode holder 257 does not block the return of the wire holder 172 to its initial position.

After the cams 168-170 have returned to their original positions the clutch is disengaged again by stopper 184. With each excitation of the solenoid 188, the shaft 167 leads only one full turn. Shortly after the shaft 167 begins to rotate, the solenoid 188 is switched off again.

When the connection station for isolating the conductor of the from the bottom of the toroidal core 14 coming winding wire of the then on the carrier plate 17 rests, is used, the two claws 205 and 206 touch the surface of the carrier plate 17 in front of the winding wire 11 in the In contrast to the situation in which the winding wire 11 from the top of the toroidal core 14 comes. Since the lowermost end of the claws 205 and 20β simultaneously touches the surface of the carrier plate 17, are they led against each other. As a result of the simultaneous movement of these two claws 205, 206, the one on the carrier plate 17 becomes Part of the winding wire properly aligned and held between the two claws 205, 206. The winding wire 11 remains on the surface of the carrier plate 17 and is not removed from this position.

To supplement the above description, it should be noted that the Method according to the invention for the mechanical winding of toroidal cores
