  • the selector meansfor the lines onthe' plate comprise a logic circuit means defining an electronic matrix having a grid or treelike arrangement denoted in its entirety by 126, so as to avoid any error during the transition from one angular position to another.
  • This matrix is connected on the one hand to themanual'selector keyboard 104 and, onthe other hand, to a detector system-127 with photosensitive elements (FIGS. 2A and 4) associated with a code 128 (cf. also FIG. 3), carried by a disc 129'fixed on thearbor 100 of the plate-carrying cylinder (cf. also FIG. 4).

  • Each of the six cells 127-1 to 127-6 controls an electronic bistable flip-flop such as 133-4 and 133-1 which correspond to the two cells 127-4 and 127-1 which read the tracks of code 128, corresponding to the impression of the l3 line on a sheet of paper.
  • Each flip-flop e.g. 133-1, comprises two outputs 133A and 1338 connected to corresponding input 134A and 1348 of matrix 126, which thus comprises 12 inputs.
  • the other inputs of the matrix have been indicated respectively by BSA-135B, 136-1368, 137A-137B, 138A-138B, and 139A-139B.
  • the keyboard 104 comprises as many selector keys as there are lines capable of being printed, i.e. 39.
  • selector control key 141-13 for the 13th line of the plate has been indicated.
  • This key is urged towards its upper inactive position by a return spring 142 and it can be kept in the active position by a locking pawl 143 cooperating with a catch 144 integral with the stem of the said key.
  • Hocking pawl 143 is urged towards its position retaining the key by a spring 145, and it can be removed from this position by another catch 146 carried by a releasing bar 147.
  • Each key such as 141-13, actuates an inverter or doublepole switch such as 151-13, a switch such as 152-13 and another switch such as 153-13, which supplies a pilot lamp. 154-13.
  • the central contacts of all the inverters such as 151-13 are connected to the corresponding outputs, such as 157-13, of the matrix.
  • each inverter is connected to the control circuit 159 of electromagnet 115 controlling the driving connection between the printing cylinder and its motor, as well as to the upper contact of the corresponding switch 152-13, and to the lower contact of the switch controlled by the selector key of the preceding line.
  • the lower contact such as 156-13 of each inverter is connected to the control circuit 115 of the electromagnet 118 for controlling the printing.
  • the lower contact of switch 152-39 of the last line is connected to the control circuit 161 for the electromagnet 121 actuating the pincers.
  • the power supply for the matrix 126 is effected via contacts 164 of a step relay controlled by a manual control button 166.
  • the step relay 165 comprises a retaining contact 167 itself supplied via the contact 168 of a stop relay 169 whose coil is supplied by the last output 157-40 of the matrix.
  • the electromagnetic clutch means 115 for the plate-carrying cylinder is also subjected, through the intennediary of a rocker 172, to the action of a contract 173 cyclically actuated by a cam 174 fixed on the arbor 119 belonging to the printing control system, as well as of a contact 176 actuated by a roller 177 cooperating with the cam 124, which has 46 teeth.
  • the pushbutton step" 166 is depressed, the step relay 65 is actuated and is held by means of its autoretaining contact 167, whose circuit passed through the closed contact 168 of the stop relay 169.
  • the closure of contact 164 of the step relay puts the decoding matrix 126 under current.
  • the circuits, such as 1338 of the cell amplifiers then close, passing through the resistances 170-1 to 170-40 of the matrix. All paths save the first are then closed, the power at the entry to paths 2 to 40 being greater than that of the bases of the transistors of the movement-controlling amplifiers.
  • the rotation-control circuit 159 is then closed by the contact 158-1 of the inverter and the first path of the matrix.
  • THe electromagnetic clutch means 115 of the coupling controlling the rotation is actuated, and cylinder 102 turns, carrying with it code 128; after an angular displacement of the cylinder and of the code, by an angle equal to the angular interval separating two lines of the plate, the code changes; cell 127-1 is illuminated, output 133A of its amplifier becomes conductive, resulting in the blocking of path 1; on the other hand path 2, previously blocked by output 1338, is opened; the rotation-control circuit then passes through contact 158-2 of the corresponding inverter to key 141-2 of the second line (if this one has not been selected), and through path 2 of the matrix.
  • the rotation circuit is cut off by contact 158-13 and the printing circuit closed by contact 156-13.
  • the code is positioned at the 13th line, cells 127-1 and 127-4 alone will be illuminated; the outputs such as 133B of the two corresponding amplifiers will not longer be conductive, so that path 13 opens; the rotation circuit being cut by contact 158-13 of the inverter corresponding to the 13th line, the rotation of cylinder 102 stops; on the other hand, the printing circuit is supplied through contact 156-13 and path 13.
  • THe electromagnet 118 controlling the printing mechanism is actuated, and cylinder 102 drops to print the 13th line on the sheet of paper which is at that moment stationary, since pincers 103 move on the table in a synchronous fashion with the movement of rotation of the plate-carrying cylinder.
  • This machine allows simultaneous printing on several superimposed sheets separated by sheets of carbon paper, or equivalent layers.
  • the cylinder is again rotated by the rocker controlled by contact 173, closed by cam 174 mounted on the printing-control arbor.
  • the exploration of the paths is then resumed by the reading-system for code 128, which is once more in rotation.
  • the stop relay 169 When the last path 40 is open, the stop relay 169 is actuated; its contact 168 opens and cuts off the retaining circuit of the step relay the latter, returning to the rest position, cuts off the supply to the matrix for the opening of its contact 164; cylinder 102 then stops on the following path, and a delay brought about by a condenser 181 and a resistance 182, connected in series at the limits of step relay 165, ensures the continuation of the movement of the cylinder from the 40th path to the first.
  • the pincer-control circuit 161 is supplied in parallel with the rotation-control circuit as soon as the last line selected has been printed. This is obtained by setting in series contacts 152-1 to 152-39 corresponding to each key; if a single one of these contacts is open, i.e. if one single line is selected, the pincer circuit will only be supplied once the matrix path corresponding to the line following the selected line is open.
  • the reading device might be fixed, if the exploration begins only after the complete return of the reprinting cylinder to its raised position.
  • a printing machine having a table for supporting a sheet of paper to be printed, actuatable means for gripping and holding the sheet and movably mounted with respect to the table for advancing a sheet held thereby, a rotatable printing cylinder carrying a plate having a number of lines of type disposed circumferentially about said cylinder, a rotation control device including clutch means for transmitting driving torque from a motor to said cylinder, a printing control means for causing said cylinder to move into printing contact with said sheet while said sheet is temporarily held stationary by said gripping means and while said clutch means is inoperative, means for controlling the angular position of said cylinder to bring a selected line of said number of lines of type into printing position, the improvement comprising a first electromagnet adapted to actuate said clutch means, said printing control means comprising a second electromagnet, and a third electromagnet adapted to actuate said gripping means, said means for controlling the angular position of said cylinder including a logic circuit means defining an electronic matrix arrangement having a
