  • the present invention concerns a device for the automatic preparation of perforated cards or paper bands for Jacquards, of the kind wherein the color information received from a photo-electric system which scans by successive lines the design illustrating the warp and weft threads of the fabric to be woven, is combined with the weave information derived from a record which advances in synchronism with the scanning of the design, in order to generate signals to control a perforating machine.
  • such a device comprises weave circuits each in the form of a grid including 'two sets of electrically insulated bars adapted to correspond respectively to the warp and weft threads of the weave, each bar of a set being connectable with any bar of the other set by means of a removable plug, with the bars of the first set receiving in succession a signal each time the photo-electric device scans another thread in one of the groups formed'respectively by the warp and weft threads, and with the bars of the second set being connected with the outlet of the circuit through gates controlled in succession by signals which occur each time the photo-electric system scans another thread in the othergroup, in such manner that for each crossing of a thread of the first group with a thread of the second group each weave circuit only generates a weave signal on its outlet if the bars which correspond to these two threads are connected with each other by a plug and a combination circuit which receives the weave signals from all the weave circuits and the color signals from the photo-electric system in order to send a coincidence signal to the
  • the distribution of the perspective signals to the bars and to the gates is preferably insured by shift registers actuated by appropriate signals a short time before the photo-electric system scans a point of the design.

  • FIG. 6 shows another embodiment of a combination circuit.
  • a conventional weaving design is formed of a squared paper 1 on which the various squares are colored in accordance with the different weaves desired, the color of the paper itself, as for instance white, corresponding to a particular weave, generally to the background (the colors are not indicated in FIG. 1).
  • the design is read in by means of an optical system 2 which scans the successive horizontal rows of squares.
  • This device may comprise a system of lenses, a color selector and a main photo-electric cell for each color of the design. It may be supposed for the sake of simplicity that the design only comprises three colors.
  • auxiliary normal coincidence photo-electric cell 3 which moves across the design with system 2 and which emits a signal each time the latter scans the center of a square.
  • the paper 1 was provided with a lower row or thick black vertical lines which act on cell 3.
  • This auxiliary cell could also scan the vertical lines of the squared paper provided same are sufficiently thick for this purpose.
  • the coincidence signals generated by cell 3 will be thereafter designated by reference 8;.
  • FIG. 1 shows a third photo-electric cell 5 which may be considered as the advanced coincidence cell.
  • Cell 5 also scans the scale 4 at the same rate as cell 3 but with a slight fixed advance. It therefore emits a signal S, somewhat before the main cell 2 reaches the center of a square.
  • this auxiliary cell 5 could also cooperate with the vertical lines of the squared paper.
  • FIG. 2 shows a modification wherein the advanced coincidence cell 5 is no more in front of the normal coincidence cell 3, with respect to the relative displacement of the cell until in front of the paper, but somewhat behind the said cell 3. It is easy to see that if the longitudinal distance betweencells 3 and 5 is lower that the spacing apart of lines 4, cell 5 will emit a signal 8, just before the main cell 2 reaches the center of a square, except for the first one. As explained below the arrangement of FIG. 2 simplifies somewhat the operation of the shift registers.
  • the above mentioned signals C C C S and 8; which may be tenned read signals, are transmitted to a circuitry comprising a number of weave circuits and a combination circuit.
  • the weave circuits generate weave signals in response to some of the read signals.
  • the combination circuit it combines the read signals and the weave signals and it actuates in accordance a perforating machine.
  • FIG. 3 illustrates a weave circuit by means of which it is possible to realize any weave comprising five warp threads and five weft threads.
  • This circuit comprises two shift registers 6 and 7 respectively corresponding to these five warp and weft threads.
  • Each register has a shift inlet 6a, 7a and a resetting inlet 6b, 7b.
  • the inlet 70 of register 7 receives the signals 8,, from the advanced coincidence cell 5.
  • the inlet 6a of register 8 receives a signal 8,, through a conductor 8 whenever the cell unit has scanned a row of squares and is going to scan the next one, as for instance when this unit is returned from the right-hand side of paper 1 towards the left-hand side thereof while being lowered thereon.
  • the inlet 7b is also adapted to receive a signal whenever the scanning of a row is ended and for this purpose it may also be connected with conductor 8 as shown.
  • inlet 6b it should normally only be effective at the beginning of the read-in operation. It has therefore been illustrated as actuated manually. But it should be understood that the control of resetting inlets 6b and 7b could be effected in any appropriate manner.
  • each square corresponds to more than one warp thread.
  • the pulse or signal 8 may be divided by an appropriate device into a plurality of successive pulses in such manner that the effect on the perforating machine is the same as if each square of the drawing had been divided into a number of squares of the same color. It may also happen that a single horizontal row of squares corresponds to more than one weft. In such a case each row may be read in several times repeatedly before proceeding to the next one, or the reading in may be registered in an appropriate memory and repeated by same on inlet 6a before reading the next row.
  • registers 6 and 7 as illustrated in FIG. 3 are of the ring type, i.e., that at any time one only of the outlets of each is at level 1, the other outlets being at level 0.
  • the first outlet is at level 1.
  • the first inlet returns to 0 and the second inlet comes to level 1, and so on, level 1 circulating, so to speak, along the successive outlets and passing from the last one to the first one as if the register were circular.
  • Each of the five outlets of register 6 is connected through an inverter 10a to 10e with an individual conductor, respectively 11a to He, the five conductors lla-ll forming one of the two series of bars of a grid G, as explained below.
  • register 6 could be of the inverted type, i.e., one of its outlets being at level 0 and all the remaining ones at level 1, inverters 10a to We being suppressed and the register outlets being directly connected with conductors or bars 11a to 1 1e.
  • This may be realized by establishing the register by means of bistable flip-flops each having a direct outlet and an inverted outlet. It would also be possible to use a counter and to decode the outlets thereof.
  • the five outlets of register 7 they are respectively connected with one of the two inlets of NAND gates 12a to 1212. Such gates only generate a voltage at the lower level (level 0) when all their inlets are at the upper level (level 1) and therefore their outlet is at the upper level (level 1) for any other combination of their inlet levels.
  • the second inlets of gates 12a to 12c are respectively connected by wires 13a to l3e with conductors 15a to 15c which form the other set of bars of grid G.
  • grid G may receive plugs adapted to connect a bar of one set with a bar of the other set at the crossing point of the two bars.
  • the connections are as follows 10a-15a, lob-15c, 10a-15c, 10d-15b and l0e-l5.
  • the outlets of gates 12a to 12e are connected with the five inlets of a NAND gate 16.
  • the outlet wire 17 of gate 16 transmits the weave signal to the combination circuit which will be described below.
  • circuitry illustrated in FIG. 3 is at the left end of the upper horizontal row of squares of the design, cells 3 and 5 also being at the left since they move in unison with system 2.
  • the reading unit 2-3-5 is advanced towards the right in FIG. ll.
  • Cell 5 thus passes across the first line of scale 4;. It then generates a pulse 8,, which is applied to inlet 7a and which causes register 7 to advance through one unit.
  • Registers 6 and .7 are then both at their first position (position No. l), which means that they emit a signal at the upper level 1 on their outlet No 1, the four remaining outlets being at the lower level 0.
  • signal 1 from its outlet No l is transformed by inverter 10a into a signal which is applied to conductor or bar 11a and therefore to conductor or bar 15a with which the latter is connected.
  • This signal is transformed into a signal 1 by inverter 14a and it is transmitted by wire 13a to the second inlet of NAND gate 12a.
  • this second inlet of gate 12a simultaneously receives a signal 1 from outlet No. 1 of register 7. It therefore generates on its outlet a signal 0 which reaches the first inlet of gate 16. Since this gate is of the NAND type, it generates level 1 when one at least of its inlets is at level 0. Outlet 17 thus transmits signal I to the combination circuit still to be described.
  • outlet wire 17 will receive level 0 since conductor Ila is not connected to any of conductors 15b to l5e.
  • register 7 When the sixth square is reached, register 7 has returned to its position No. 1 and the cycle abovediscussed is repeated, and so on until the endof the row.
  • plugs form a direct connection between the two sets of bars of grid G. But in actual practice it may be of interest to use plugs including an electronic component and more particularly a diode adapted to prevent passage of current in the undesirable direction.
  • FIG. 1 the-advanced coincidence cell 5 is disposed in front of the normal coincidence cell with respect to the scanning direction. But cell 5 may also be disposed as illustrated in FIG. 2, namely behindv cell 3. The operation remains exactly the same with this sole difference that when the first square is being read in, this cell 5 has not yet emitted its signal or pulse 8,. It results therefrom that register 7 has not yet been shifted before system 2 reaches the center of the first square. Register 7 must therefore be brought initially to position No. 1 and not to position No. 5, which is practically more logical.
  • the circuit of FIG. 3 may comprise many modifications, more particularly concerning the gates and the inverters. It will be understood, for instance, that'AND gates could be used in lieu of the NAND gates described, since in the circuit illustrated the former realize a double inversion. Any other combination of gates and inverters could be possible, as this is clear for any one skilled in the art. It has already been indicated that with a register 6 of the inverted type (one outlet at level 0 and the remaining ones at level 1), the inverters 10a to 10b could be suppressed. It may further be noted that it is possible to provide in addition to the normal outlet wire 17, a reverse outlet wire 17a connected with wire 17 through an inverter 17b.
  • the combination circuit illustrated in FIG. 4 comprises five inlet wires ll8c 18c 18c, 18c, and l8c adapted to receive color signals from the optical reading system 2 of FIG. 11. Since in this example there are only provided three colors, only the three first ones of these wires received signals, respectively C C C the two remaining ones being grounded so as to remain at level 0. Wires 180, to 1,80 are respectively connected to five NAND gates 19c, to 19c, the outlets of which are in turn connected with the five inlets of a NAND gate 211. The outlet wire 22 of this gate is connected with an inverter 25. The outlet wire of inverter 25 transmits the controlling signal to the perforating machine, not shown.
  • the latter comprises in the conventional manner a number of elements equal to the number of possible perforations in a Jacquard card. These elements are scanned in succession in synchronism with the advance of the optical system 2 across the design (which may be obtained by means of the signals 8,, S and S in such manner that each element may assume either an effective of an ineffective position in correspondence with the voltage level on wire 26, which is easily obtained by means of appropriate relays, gates or registers. Devices of this kind being conventional in the art, they need not be described in the present specification.
  • Each NAND gate 190, to 190 includes two inlets, the second one being connected with the outlet wire 17 of a weave circuit.
  • the system comprises five weave circuits A, to A Since the design of FIG. 1 only comprises three colors, three of these five circuits should be selected, each corresponding to one color.
  • the second inlet of gates 190, to 190, which are unused are grounded in order to insure that these gates remain blocked. It is however to be noted that the grounding of one inlet is sufficient for each gate, the grounding of the second inlet being merely effected as a matter of safety.
  • Gate 23 has a second inlet 27 adapted to receive signal 8,.
  • the corresponding gate 19c is conditioned and if it also receives a signal at level l on its second inlet from the corresponding weave circuit (circuit A, in the example of FIG. 4), its outlet sinks to level 0.
  • Gate 21 no more has its inlet at level 1 and it therefore generates level I on wire 22, which conditions gate 23.
  • gate 23 will emit level 0 on its outlet 24 and inverter 25 will generate level I on the outlet 26 of the combination circuit.
  • the corresponding element of the perforating machine will be brought to its effective position.
