  • the programmed device 145 When the programmed device 145 (FIG. 11) of the machine requires a feed jump, it energizes start electromagnet 157 and presetting electromagnet 272 or 284 in the manner which will be described hereinafter. Moreover, device 145 energizes both line-spacing actuating electromagnet 208 and jump actuating electromagnet 297. Finally, the programmed device-145 selects in the photoelectric device 327 or 328 corresponding to the energized presetting electromagnet 272 or 284 that track 416 of the perforated tape 415 which is to be read to control the jump to be effected. As already seen, owing to the actuation of the line spacing, slider 221 is shifted to the right in FIG. 8. The slider 221 then deprives lug 315 of the support of shoulder 316.

  • the bail 314, however, remains locked by tooth 310 of rocking lever 312, thus tensioning spring 322.
  • the slider 221 therefore cannot be brought back to the left to produce the disengagement of clutch 234 (FIG. 7) and shaft 237 continues to rotate, producing a series of line-spacing operations on the continuous form 69, 71 selected.
  • photoelectric device 327 or 328 When photoelectric device 327 or 328 (FIG. 11) reads a hole 417 on the selected track, the hole indicating the end of the feed jump, it generates a signal which is transmitted to programmed device 145.
  • programmed device 145 causes electromagnet 297 (FIG. 8) to be deenergized, as a result of which spring 302 causes armature 298 to be moved away and lever 308, together with bar 311 and rocking lever 312, to return to the position of FIG. 8.
  • the tooth 310 thus releases tooth 313 of bail 314 which, under the control of shaft 237, now releases step 316 of slider 221 from lug 315.
  • the slider 221 is now brought back to the inoperative position by spring 222, so that at the end of the cycle ofshaft 237, lever 223 (FIG. 7) locks bail 228 in the position shown in the drawing, disengaging clutch 234.
  • the feed jump can be effected simultaneously in the two continuous forms 69 and 71.
  • the programmed device 145 selects the track 416 to be read only on one of the two photoelectric devices 327, 328, as a result of which the two forms 69 and 71 will perform equal jumps. If the two forms 69 and 71 require jumps of different lengths, the programmed device 145 can be prearranged in such manner as to command, after the common jump, a second jump for that form 69 or 71 requiring ajump of greater length.
  • cam 326 normally causes lever 325 to turn clockwise and, via slider 323, cause bail 314 to turn anticlockwise and release slider 221, which is thus brought back to the inoperative position, to the left in FIG. 8, by spring 222.
  • the programmed operating device 145 comprises an electronic unit 340 adapted to read from time to time the program information recorded on a magnetic tape in the form of separate characters for each operation to be effected, and to transmit the relative signals to a series of control circuits. More particularly, for control of the feed movements of the paper, between the electronic unit 340 and the four presetting electromagnets 138, 196, 272 and 284 there are provided four corresponding flip-flops RP, RS, SI and SS.
  • the unit 340 is adapted to switch each of these flip-flops RP, RS, SI and SS to a first operative state to energize the corresponding electromagnet 138, 196, 272, or 284, on reading of the corresponding character on the magnetic tape. In the absence of such character, unit 340 brings the corresponding flip-flop RP, RS, SI and SS back into the other state, in which the respective electromagnet 138, 196, 272, or 284 is deenergized.

  • a second arm 350 of bail 351 is connected by means of connecting rod 349 to another bail 347 pivoted on a fixed spindle 348 and normally bearing by the action of spring 344 and arm 346 on the cam 343 of actuating shaft 237.

  • the switch 362 (FIG. 11) is connected electrically to the electronic unit 340 to signal the position of rollers 101 (FIG. 2) continuously to unit 340 so as to permit simultaneously with the energization of the presetting electromagnets 272 and 284, the prearrangement of the rotation of shaft 103 if the rollers 101 are in the open position.
  • the electromagnet 297 (FIG. 11) is driven by unit 340 by means of flip-flop SAL, normally in the inoperative state, to energize electromagnet 297.
  • unit 340 On the reading of the corresponding character, unit 340 transmits a signal to a coincidence or AND circuit 392.
  • the coincidence circuit 392 On the closing of switch 270, the coincidence circuit 392 then sends a signal which changes flipflop SAL over into the the operative state to energize the electromagnet 297.
  • the flip-flop SAL is then changed over into the inoperative state when one of the photoelectric devices 327 and 328 reads the end-of-feed-jump position on the track 416 of the perforated tape 415 selected by unit 340.
