and the means are shown in Pig * 9, in -drsr the driver plate 8, the grinding device C, and the arm 4o carrying the tube 6 leading to the winding machine are shown. In this embodiment of the invention, the diametrically opposed arms 2oo and 2ö2 are connected to the arm ¹ Io via the rigid links 2o4 and 2o6 and thus move with the arm ko as a unit. The arm 2o2 lies between the area ίο and the drive unit of the grinding wheels and tt ⁱ Sgt the alignment cylinder 2o6, while the arm £ oo lies between the arm 4o and the output side of the grinding wheels and carries the alignment cylinder 2io. The switch 19ö is at the end of the path of the arm 4o in the opposite direction from the movement nor MitnehraerplatbB and controls the circuits with the windings of the magnet coils 2oS and 2io, which extend their plunger cores when excited and with the springs located in the openings of the driver plate Bring in ¥ ¥ ¥ ¥ rv © rbinding _r whereby the! pauch core of the magnet coil 2o8 completely compresses a spring which is not yet ground and the plunger core of the magnet coil 21o completely compresses a spring located in the driver plate which is already ground. The switch 186 is at the end of the path of the arm 20-2 in the direction of rotation of the driver plate and controls the circuits of the second windings

of the solenoids 2o8 and 2Io, whereby when the switching element of this switch is acted upon, these windings are excited by the arm 2o2 and the plunger cores of the solenoid are drawn in and the active connection with the springs located in the driver plate is released. Then the arms ¹ Io, 2oo and 2o2 are moved by the means already described in connection with the other exemplary embodiments of the invention in a direction which is opposite to the movement of the take-away plate and when the arm * to reaches the end of its path in this direction, then the switch I9o closes and excites the corresponding windings of the magnet coils 2o8 and 2io, whereby the plunger cores are brought into operative connection with the next springs delivered to the driver plate and the working cycle is repeated.

In the practical operation of the winding, grinding and aligning machine according to the invention, there were sometimes difficulties with the passage of the formed spiral springs from the winding machine on the grinding and aligning machine and therefore means are provided according to the invention to facilitate this passage, which ensures that. the tube or tubes that lead from the winding machine to the grinding machine are not clogged ₉ thus reducing the possibility of damage to the? Machine and the security of a

Io and Ii are shown, in which 3oödie means winding machines A, 3o2 represents a “partially wound spring”, 3o4 a tube leading from the winding machine ssuni driver B of the grinding machine, which according to certain embodiments of the invention can be an oil tube or according to the in the Pign * k, $ and δ shown embodiment can consist of a multiple pipe system.

Between the end of the pipe3ο4 _? DVH. "wipe the winding point and the upper end of the pipe 3o $ is a Hilfj & pipe 3o6 (which may form a konstruktlons · moderate unit with the pipe 3o ^), the internal diameter of the of the pipe is equal to So ^ and the at one end to Pipe 3o4 is connected. Aa other "end of the pipe 3o6 is derWickelpunkt be added to the dl" su-winding springs, and co »the drawing io show that the partially coiled spring finely occurs 3O2 straight into the inlet end of the tube 3o6, while a ready in the pipe The fully wound peder 3o8 is located * A carrier 3io is held by the winding machine 312 and has a part 314 * which encompasses the tube 3o6 in order to keep it in the described position in relation to the winding point and the tube 3o4.

According to the invention, means are provided for transporting the springs along the tube 3o6 in order to ensure that the angled springs are inserted into the tube 3o * 1 and fed through the tube to the driver of the grinding machine. These means consist first of all of a groove 32o, which is located in the wall of the tube 3οβ and extends right through it, as shown in FIG. 11. A wheel 322 mounted on the shaft 322 of the electric motor 326 attached to the frame of the winding machine protrudes sufficiently into the groove 32o and comes into operative connection with the outer catch of a spring wound at the winding point, which is located in the tube 3οβ bsw. located at its inlet port. The circumference of the wheel can be provided with rubber, wire, bristles or some other suitable material which comes into singular engagement with the circumference of the spring and which inevitably misses along the tube 3o6 to the inlet end of the tube 3 © ft.
