  • This invention relates to an apparatus for continuously recording ink-jet pictures. It comprises a rotor on whose cylindrical surface rests a recording support, and an annular ink-jet system.
  • ink or coloured liquid is extruded under high pressure through a nozzle (capillary), Immediately downstream of the noule is an annular control electrode. A voltage U is applied between this electrode and the'conductive ink or coloured liquid. When U exceeds a certain limit (about 200 volts), the jet of ink breaks up into small droplets. The higher the voltage U, the greater is the degree of disintegration.
  • An object of the invention is to provide an apparatus for the continuous recording of ink-jet pictures which gives high picture quality and is relatively simple and compact in structure. It is armed to do this with as few ink nozzles as, possible so that only a correspondingly small number of transmission channels need be used. A small number of transmission channels means less Outlay in terms of electronics ans also far less troubleprone operation.

  • the guide rollers 10a and the supply roll 13 are provided with a friction brake.

  • the supply roll 13 is arranged on the rotor axis 15 and not inclined thereto.
  • the recording sheet 8 is directed into a helical path on the rotor surface by the guide roller 16 whose axis is directed obliquely of the rotor axis 15 and hence obliquely of the axis of the supply roll.
  • the angle of inclination 'y, at which the recording sheet 8 moves into its helical path is governed both by the angle a of the axis of the guide roller 16 with respect to the rotor axis and by the looping angle g of the recording sheet 8 around the guide roller 16.
  • the values of -y, a and g are related by the equation a 'y-g. If, for example, the looping angle g is one-half, the angle a between the guide roller 16 and rotor axis 15 is half as large as the angle y at which the recording sheet 8 moves into its helical path. Since as operation continues the diameter of the supply roll 13 becomes progressively smaller, the looping angle g and hence the helical-path angle 7 would alter continuously in the absence of any additional measures. For this reason, additional guide rollers 17 are provided to ensure that the looping angle g remains constant. Similarly, guide rollers 16 and 17 are also arranged in the vicinity of the take-up roll at the other end of the rotor. One of the guide rollers 16 is again responsible for sheet advance.

  • the number of loops of the recording sheet 8 around the rotor 2 between entry and contact determines the size of the area available for the ink nozzles 7. For one complete loop, this area is equal to zero. In the case of a double loop, and if it is assumed that the sheets 8 lie close together, the area F available for the ink nozzles 7 is given by:
  • the picture trace of an ink nozzle 7 appears as a spiral line on the stretched recording support due to the rotation and simultaneous translation of the recording sheet, it is important to know the extent of the interval, more particularly the vertical interval, between two picture traces because this interval determines the number of ink nozzles 7 which have to be used to fill the gap between these ink traces with further ink traces.
  • FIG. 9 illustrates parameters governing this which are explained in the following, and the flattened recording sheet of one loop in its correct position to the rotor axis with the ink traces produced on the basis of the V speed of the recording support relative to the rotor V resulting speed of the recording support when V and V have substantially the same direction.
  • the angle at which this speed is reached is desig- VI rEs uIti ngspeed of the recording support when V and V are substantially oppositely directed.
  • the corresponding angle is designated B If the conditions are calculated with the parameters defined abovggz cording to FIG. 9, then:
  • the arrangement described above is distinguished by the fact that, in addition to the rotation of the rotor 2, the recording sheet makes a helical movement onthe rotor surface 5. Accordingly, the recording sheet 8 spontaneously makes both a rotary and also a translatory movement.
  • FIG. 10 An alternative embodiment which has also proved to be effective is shown in FIG. 10.
  • the recording sheet 8 only makes a translatory movement.
  • the rotary movement relative to the stationary nozzle system 6 is made solely by the rotor 2.
  • the supply rolls 13 and take-up rolls 14 are arranged opposite one another at the ends of the rotor 2.
  • the recording sheet 8 runs over the rotor surface parallel to the rotor axis 15. Since the recording sheet 8 is fairly thin and is not very stiff against flexure according to its inner consistency, it is readily possible by maintaining a certain minimum interval between the supply rolls 13 and take-up rolls 14, to deform the sheet in such a way that it applies itself uniformly to the cylindrical rotor surface.
  • pairs of contact rollers 18 ensure that the recording sheets 8 are uniformly applied to the rotor surface in the vicinity of the annular, stationary nozzle system 6.
  • the entire system including the supply rolls l3 and take-up rolls 14, rotates about the rotor axis 15.
  • the recording sheets 8 follow a translatory path, i.e. from the supply rolls 13 to the take-up rolls 14 in the direction of the rotor axis 15.
  • the annular nozzle system is arranged substantially in the middle of the-rotor 2.
  • the interval b between two ink traces after one revolution is given by the relation where V sheet speed in the direction of the rotor axis V, tangential speed of the rotor at the rotor surface,
  • the transition of the recording sheet 8 from the flat form at the supply rolls 13 into the curved form onthe rotor surface 5 is facilitated by a special configuration of the rotor 2 at its ends'(cf. FIGS. 11 and 12).
