8εδι \ ΕΓδ? 0? 9b.Z S

F i g. 3 shows a section along the line 3-3 in FIG. 2,

4 shows a schematic representation of a biconic Coil with a ring bank.

According to FIG. 1, a drive motor 12 with gear 13 is arranged below a machine frame 11. On the machine frame 11, a pair of guide rods 15 is attached, on which a A pair of plate-shaped stroke limiting members 16, 17 and a guide block 18 are slidably arranged are. The guide block 18 carries a twisting ring 21 with a twisting rotor 22 (FIG. 4), over the a thread 23 is fed to a bobbin tube 26. The bobbin case 26 is concentric within the Ring rail 21 arranged and rotates at a certain speed.

The stroke of the ring rail 21 on the guide block 18 is determined by the position of the plate-shaped stroke limiting members 16 and 17 determined. This stroke is continuous to produce a biconical coil reduced during the winding process in that with the aid of a screw spindle 30 the stroke limiting members 16 and 17 with opposite thread pitches at their two ends are led against each other. The screw spindle 30 is connected to the drive motor 12 via the gear 13 driven and connected to the stroke limiting members 16 and 17 by spring-loaded threaded jaws 32. The threaded jaws 32 are releasably attached to the stroke limiting members 16 and 17, see above that, if necessary, the stroke limiting members 16 and 17 can be moved freely on the guide rods 15 can. By means of collars 36 and 37 provided on the guide rods, the Position of the stroke limiting members 16 and 17 can be set at the beginning of each winding process.

An endless V-belt 40 runs over pulleys 41 and 42 on the machine frame 11 or are arranged on the transmission 13. The disk 42 is driven via the gear 13. The direction of movement the belt runs parallel to the longitudinal axis of the bobbin case 26.

The guide block 18 carries in a recess a driver block 50, both of which the belt strands facing sides are provided with grooves 51 and 52, which in their cross-section of the cross-sectional design of the belt 40 correspond. The respective belt section runs between one of the Grooves 51 and 52 and corresponding surfaces 53 and 54 of the guide block 18. A circular one Eccentric disk 60 can be pivoted about a pin 61 in a recess 62 on guide block 18 stored. An edge 63 extending over a semicircle on the eccentric disk 60 can be under the action of a strong tension spring 69 on the side walls 65 and 66 of the recess 62 create and thereby move the driver block 50 in the respective installation direction. The spring 69 is with its one end on an eyebolt 70 and with its other end on one in the edge 63 the eccentric 60 attached eyebolt 71 is suspended.

At one end of the edge 63 of the eccentric 60, a pin 75 is provided which is in a Groove 76 running transversely to the direction of movement of the ring rail engages in a rail 77. the Rail 77 is slidable in a corresponding groove 78 on the driver block 50 and by a Plate 80 prevented from falling out. The ends of the rail 77 protrude above and below the guide block 18 and meet at the respective end of the stroke of the ring rail on the stroke limiting members and 17 on. As a result, the pin 75 and with it the eccentric disk 60 in the groove 76 top dead center pivoted into an unstable position, from which the eccentric disc by the action the tension spring 69 is suddenly pivoted into the other stable position. This becomes the driver block just as quickly moved in the opposite direction and that on the corresponding one The belt section lying on the side is clamped between it and one of the surfaces 53 or 54 on the guide block 18.
