The pilots of the two electrovalves 16 and 17 are connected electrically to switch 18. The latter has two positions x and y, which provides for the reversibility of the system.
  • a reel carrying drum 201 As indicated in FIGS. 5 and 6, a reel carrying drum 201, with the shaft 4, is fastened to a frame 202. On this drum 201, which is hollow, are mounted radially, cross bars 203, 204 and 205 which are movable in the longitudinal guide holes 206, 207 and 208 provided in the drum along generatrices distributed at 120. These cross bars carry fingers 209 spaced from one another by the thickness of a reel. Between these fingers are housed reels 3a, 3b 31'.
  • Cross bars 203, 204 and 205 are movable longitudinally on the drum, respectively in guide holes 206, 207 and 208 under the action of a jack 211 located at the end of shaft 4 on which are wedged two cams 217 and 218. The latter drive the cross bars by means of their shoulders 228.
  • the base of jack 213 is connected to frame 202 through an axis 229.
  • Shaft 4 is integral, in rotation, with disc 216 through a key 230 crossing shaft 4 in a guide hole 231 whose length is such that the longitudinal displacement of 4 has no effect whatsoever on disc 216.
  • cams 217 and 218 Keyed onto shaft 4.
  • These cams comprise guide holes 219, 220, 221 in which are housed pins 222, 223 and 224 of cross bars 203, 204 and 205.
  • jacks 211 and 213 are fed with air under pressure through line 225 by means of free piston distributors 226 and 227.
  • the distribution of air for the purpose of displacing each jack in one direction or in the other is effected under the action of pulses generated by circuits B, C, D and E, circuit B controlling the forward displacement of shaft 4 and circuit C its return rearwards, circuit D controlling the displacement of fingers 209 within the drum and circuit E their displacement towards the outside of the drum.
  • the pulse along circuit B acts to displace the slide of distributor 226 towards the left.
  • circuits are connected through relays to a program which provides suitable pulses according to a set order.
  • the pulses are given in the following order, B, D, C and E, it being specified that the unit from 213 to 216 is provided so that the intervening action of circuit D will cause the rotation of cams 217 and 218 in the direction of arrow F (FIG. 6) and of circuit E in the reverse direction.
  • the device as a whole operates as follows.
  • ends la, 1i are arranged on drum 7, the surface of suction drum 9 being cleared and strip 101 unwinding from reel 102.
  • Suction circuit 12 is opened and the ends of the strips are maintained on drum 7.
  • Suction circuit 14 is closed.
  • Jack 6 begins to act and displaces slide 5 towards drum 9. End 1a is thus placed on the surface of drum 9.
  • Suction circuit 14 is then closed and suction circuit 12 is opened. Jack 6 returns slide 5 to its starting position. 7
  • End 1a is maintained in place, through suction on drum 9.
  • End 1b displaced as a result of the motion of slide 5 into the position occupied by 10 before its displacement, is maintained in it through suction acting through perforation 11.
  • each end of strip 1b 1i will again be in the position occupied by the preceding end.
  • the corresponding reels are displaced in synchronism as this displacement of the ends of the strips is taking place.
  • Reel 3a is to be drawn out from drum 201 so as to bring it towards the utilization station, or, further, the mandrel is to be removed from the emptied reel 3a assuming the unwinding of this reel occurs on drum 201, the end of the latter, on which the reel is resting, being driven into rotation in this case, by any appropriate means.
  • jack 211 is actuated and causes shaft 4 to advance by one spacing, i.e., the thickness of a reel, towards the right end of FIG. 5.
  • Disc 216 remains stationary in position.
  • Shaft 4 being connected to cross bars 203, 204 and 205 through cams 217 and 218, these move driving with them reels 3a, 3b 3i housed in the spaces formed by fingers 209.
  • reel 3a Since the motion effected corresponds to the thickness of a reel, reel 3a is then cleared of drum 201 and is taken up again by any appropriate means. Reel 3b then occupies the place previously occupied by reel 3a.
  • Jack 213 is then set into action, arm 214 moves upwards and, through axis 215, drives disc 216 into rotation, jack 213 moving into rotation around axis 229.
  • Disc 216 keyed onto shaft 4, drives the latter into rotation as well as cams 217 and 218 in the direction corresponding to that of arrow F of FIG. 6.
  • the rotation which is effected corresponds to an angle equal to that of the opening angle of guide holes 219, 220 and 221.
  • Pins 222, 223 and 224 are driven towards the center as well as cross bars 203, 204 and 205 and fingers 209 which are integral with them. This motion acts to cause the cross bars to descend inside guide holes 206, 207 and 208 until the fingers have been moved away from the surface of drum 201.
  • Jack 211 is then set into action in the opposite direction in order to return shaft 4 to its starting position.
  • the cross bars are thus returned backwards, and fingers 209 recover, on the surface of the drum, and
  • Jack 213 is then actuated in the reverse direction in order to return disc 216 to its original position.
  • This rotation of disc 216 actuates that of shaft 4 and of cams 217 and 218 in a direction which is the reverse of that indicated by arrow F, the latters angle of rotation being equal to that over which they had previously rotated.
  • Pins 222, 223 and 224 move away from the center, causing cross bars 203, 204 and 205 to rise up into guide holes 206, 207 and 208, which cross bars cause fingers 209 to come out of drum 201, these fingers taking up their place again between the reels.
  • the device operates as follows:
  • suction drum -9 is progressively set into motion, driving strip 2a with it. This can be obtained using a variable speed motor, relayed, through an electromagnetic connection, by the motor of the machine driving strip 101.
  • Jack 130 is then set into action causing driving roller 129 to descend and press strip 2a onto drum 9, this operation being effected in order to obtain a cut under the best conditions.
  • jack 122 is set into motion pushing the guide rod towards the left (in the case of FIG. 8).
  • That part of strip 2a, upstream of the sectioning point is maintained through suction on drum 9 and advances forwards.
  • roller 132 As guide rod 121 pursues its advance, the small roller 132, which was supported by cam 131 falls from the latter. Arm 133 goes down and by pivoting around axis 134, arm 135, which carries knurling roller 112, goes down, pressing strip 101 onto strip 2a. Roller 112 is set into rotation around its axis 113 through friction against drum 9 and, through a series of knurling points, joins in a known manner the new strip to the old one.
  • Guide rod 121 in a forward thrust bearing, stops and jack 122 returns it to its starting position.
  • knife 115 remains stationary, since pinion 124 is not set into motion clue to free wheel 125.
  • small roller 132 recovers cam 131 and knurling roller 112 rises again.
  • jack simultaneously lifts up again driving roller 129.
  • Reel 102 is then simply ejected and reel 3a is then passed instead of the latter.
  • a new reel is then introduced at the place previously occupied by reel 3a so that there may be a possibility for a new junction.
  • knife 115 and driving roller 129 must be moved away from the path of strip 2a, which is effected by actuating jack 136 which, upon its withdrawal motion, drives arm 137 on which are mounted the axes of knife 115 and driving means 129.
  • the resetting of the device into operation will simply comprise reversing the suction circuits, i.e., imparting of a sucking action to slide 5 during its displacement in the direction of the frame and inactivation during the reverse displacement and arranging separately each end of the new strip both from drum 9 and on the end of slide 5 when said end is plumb with drum 9.
  • switch 18 In normal operation, i.e., when the ends of the strips are displaced from slide 5 towards drum 9, switch 18 is at position X. The electric connection is then such that when jack 6 displaces the slide towards drum 9, the suction occurs in circuit 14 and when the jack returns to its starting position, the suction occurs in circuit 12.
