   This last movement is necessary in order to allow movement of a bed spring whenever two striped coil springs have been connected, without interference with the cutter group.
Normally, two spiral connecting pieces are fed simultaneously in order to connect the upper and lower windings of adjacent rows of coil springs. Four groups or devices are normally used to twist or wind the two ends of each connecting piece. This toriion or winding of the ends of the connecting piece.

  Power is supplied to the machine from a r '; S8n u - at 110 volts z5 which is connected to a priiicipp-1 z. and which, through Conductor LrS 5 connecting said switch to a step-down transformer 66, supplies low voltage current in conductors 67 and 68. Said main switch is shown with four central terminals to which the switch blades are connected, four terminals on the right intended to be connected by said blades with the terminals
 EMI11.2
 corresponding central units, and four terminals on the left é ,, 7, lenierLt designed to be connected by said blades to the central terminals.



    Thus, the main switch 64 actually comprises a set of four two-position single-pole switches. The solid line position of the blades, as shown, connects the machine for normal or automatic operation. The dotted position of said arms connects the machine for manual or adjustment operation.



   The machine, as envisioned, comprises a cycle timer 69 which is shown in Figure 4 as including a motor which drives a shaft 61, a set of individually adjustable cams 72, 73, 74, 75, 76, 77 and 78 mounted on said shaft, a set of
 EMI11.3
 switches 79,80, 81, 82, 83, 84 and 85 operated by the corresponding cams 72 to 78, and a solenoid 86. Among these switches the switch 80 is normally closed, the switch 85 is a bipolar switch with one position and the others are normally open when the timer is idle and before the start of an operating cycle.



   The machine is equipped with a green indicator lamp 57 which

 operating cycle.



   The electrical connections of the above elements will be described in detail during the following description of an operating cycle:
The main switch 64 is set to the "automatic" position, i.e. the solid line position of Figure 4. The machine is then started to bring the means 14 and 15 to two adjacent rows of coil springs 16 in the desired position, as shown in Figure 3, to be connected by spirals, upper and lower 17. As a result, the shafts 57 rotate and, during the operating cycle, make one turn full.



   After the cam means 18 and 19 have brought the bars
40 and 41 and the cooperating means 42 and 43 thereon towards each other, the cam-shaped tab 58 on one of said shafts 57 momentarily closes the switch 59. If the normally closed switch 60 is effectively closed, a low voltage electrical circuit intended to switch on the solenoid 89 is fired. between conductor 68, main switch blade 90, conductor 91, series switches 59 and 60, conductor 92, solenoid 89, conductor 93 and conductor, 67.

   This energization of the solenoid 89 brings a valve 4 to a position - as shown - which sends compressed air to the cylinders 55 - in order to force the upper rods 52 down and the lower strips 52 up and, by Therefore, straighten the toggle means 44 and 45 and lock the means 42 and 43 of the bars :: 40 and 41 in the position of holding the coil springs. If everything is normal, the toggle means on straightening up will close all four toggle switches 56.



   'Since the switches 61 and 62 are not closed, the closing of the toggle switches 50 (establishes a low voltage electrical circuit intended to put the solenoid 80 in setion, said cireuit passing through the conductors 67,93 and

Therefore, the circuit established by closing the switch. 84 includes a conductor 119 between this com-

   Thus the circuit for solenoid 36 differs from that of solenoid 34 and j4r in that it does not include switches 56. In all other respects, the three circuits are identical.

   It is obvious that a separate control circuit for the torsion devices can be omitted if the torsion and cutting systems are mechanically connected in such a way that they act successively when closing the actuating circuits of the knives, Under such conditions, valve 37, solenoid 36, and cam 77 with its switch 84 may be omitted and control connections may take place through cam 75 and switch 82.

  The sliding means 2ili2 comprises a novel feature in that it is provided on the end of the groove 229 of each bar 225, a plpque or celé 234 which is substantially the same thickness as the diameter of the wire used to form. the coil springs 16.



   Means 212 and substantially analogous means 211 are fixed and vertically spaced such that the springs 16 must be compressed at the end in order to pass between the upper and lower slide bars. Thus, the springs seek to expand. Since the rear ends 235 of the wedges 234 end in front of the grooves 229 (Figure 8), it is evident that the coil springs, as they leave the ends of the wedges, will expand to come into contact with the surfaces 236 of the bars. 225. Therefore, the end windings 233 of said springs beyond the ends of wedges 235 are more spaced than the windings with the springs located between the upper and lower wedges.

   It follows that said windings of the adjacent rows of coil springs 16 can only overlap in one way, namely that the windings of the second row overlap the inside of the windings of the first row, as clearly shown in the figures. 5 to 8. By such control of the overlap, the stamping means 217 and 218 can suitably form on the overlapping portions of the windings (Figures 3 and 7) and the coil 17.

   Between the bearings for the shaft 425, the latter is provided with a laterally directed stud 430 which is mounted in an entraining bend 431 and therefore can rotate on its axis.



   The loop forming means 412 have a customary shape and in this case comprise a length of bprre 432 fixed in a seat provided at the end of the shaft 425 and formed at its projecting end so as to present an eccentric wall. 433 in which a transverse groove 434 is made.



  A 435 stud is available? parallel to the wall 433, this stud preferably being offset with respect to the axis of the shaft 425, in the direction opposite to the eccentricity of the wall 433.



   The means 413 comprise a sleeve 436 around the shaft 425, a bracket 437 in which said sleeve is fixedly connected, by means of a tightening screw 438, and opposite upper members 439 and 440, the first intended for come into contact with the plate 415 so as to stop the bracket 437 in one direction and the

   The fluid means 414 are represented in the form of a cylinder 444 mounted on the bracket 424 and in which one slides. piston suggests by piston rod 445. The latter is read back to square 437. The cylinder / of the double acting type and therefore has spaced connections 446 and 447, one for the fluid under pressure intended to advance the shaft 425 and the other for the fluid intended to bring this same shaft back.



   . ¯In the spring machine, the feed path of ,,) a spiral connecting piece, is above and outside: the means 412 when the shaft 425 is brought back. When the present device is installed in the inverted position, relative to the upper lipison part of the two parts fed into such a machine, the shaft brought back would be located above this connecting part. In any event, the means 412 is outside the normal path of movement of a workpiece - the spiral connection.



   After such advancement of the connecting piece and its separation, at the feed end, from the main part, each connecting piece has two ends 448 which the present device is able to twist into a loop 442.



   When pressurized fluid is supplied to connection 446, means 414 acts to project shaft 422. The first function of cam groove 441 is to create a lifting force on stud 430 ot. therefore, lifting the shaft 425 until it is stopped by the head 426 contacting the wall 427. This brings the;:; or- jon 429 out of the recess 423. As can be seen, said recess is somewhat larger than the stud and limited rotation of shaft 425 can take place during this first movement of the cam sleeve.

   This movement brings the wall 433 and the stud 435 into the overlapping position on either side of the end of the connecting piece 448, as shown in Figure 14, the beds
