Definitions

  • De present invention relates to the field of flexi­ble printing plates and in particular to the fixing of such printing plates on printing cilinders.
  • the flexible printing plates often used in modern printing techniques have to be fixed to a printing cilinder to be used in the printing process.
  • the location thereof has to take place very accurate as the picture to be produced by the printing plate has to be provided exactly on the right location on the material to be printed.
  • the requi­rements for accuracy become even greater when the material to be printed has to be printed subsequently with different co­lours.
  • it is of utmost importance that such flexible printing plates are positioned as accurate as possible on the printing cilinder.
  • the present invention provides an apparatus and the method, according to which the printing plates can be applied very accurate on the printing cilinder.
  • an apparatus for positioning a flexible printing plate comprising at least two marks on to the printing cilinder, in which at least two light sources have been provided to project positioning markings at the lo­cation of the marks to be fixed.
  • this apparatus can also be used for printing pla­tes already existing. Thus it becomes possible to fix prin­ting plates on the printing cilinder with a substantial amount of accuracy.
  • the apparatus depicted in fig. 1 comprises a frame 1 with two guiding shafts 2, onto which two movable supports 3 have been provided.
  • Each of the supports 3 comprises two suspension wheels 4, onto which a pushing cilinder 5 can be located.
  • the pushing cilinder 5 can be fixed onto the suspen­sion wheels 4 by means of fixation wheels 6, which have been provided through a bracket 7, a rack 8 and a guiding element 9.
  • the printing cilinder 5 locted on the supporting wheels 4 can rotate freely.
  • two plates 10 have been fixed, through which two guiding shafts 11 have been provided such that these are parallel to the shafts of the printing cilinder 5.
  • Two yokes 12 are movable along these guiding shafts 11 and in each of the yokes 12 a laser light source 13 has been provided.
  • Each of the laser light sources 13 is driven by means of a spindle shaft 14, which is driven by means of a motor 15.
  • both laser light sources emit a narrow ray of laser light downwards unto the printing cilinder 5.
  • two for instance cross-shaped po­sitioning markings 16 are projected on the printing cilinder 5.
  • Each of the motors 15 is connected with a control unit 17, which can dictate the position of both laser light sources 13 by means of the motors 15 and the spindle shafts 14.
  • a pressing roller 18 has been provided to the frame such by means of two yokes 19, that this pushing roller 18 can be located adjacent with the printing cilinder 5, in which account is taken of printing cilinders with different diameters by the movability of the pushing roller 18.
  • the po­sition of the pushing roller 18 is adjustable by means of two spindle shafts 20 which are actuable simultaneously. Both spindle shafts 20 are driven by means of a hand wheel, a dri­ving shaft 22 and several conical gear transmissions 23.
  • a coupling apparatus 24 At the outer side of one of the yokes 19 a coupling apparatus 24 has been provided, with which, when the pushing roller 18 as adjacent to the pushing roller 5, both rollers are connected for rotation.
  • the pushing roller 18 comprises a dri­ving motor 25, which drives the pushing roller 18 through a worm-wheel transmission 26.
  • the position of the marks 28 located on the printing plate 27 are fed in the con­trol unit 17. It is, of course, also possible, that only the number of the printing plate 27 has to be entered and that the control unit 17 comprises a memory, in which, except the number of the relevant printing plates, also the coördinates of the marks belonging thereto have been stored. Subsequently ly, the control unit 17 will make the motors 15 drive the la­ser light sources such that the laser light sources 13 both take such a position, that the required positioning markings 16 are projected on the relevant cilinder 5 on the required position.
  • the printing plate 27 can be positio­ned such on the printing cilinder 5, that the markings pro­jected co ⁇ ncide with the marks 28.
  • the pushing roller 18 is driven by means of the motor 25, through which through the coupling apparatus 14, the printing cilinder 5 is driven and the printing plate 27 is provided in the right position on the printing cilinder 5.
  • the back layer of the printing plate 27 or the circumference of the printing cilinder 5 has been provided with a suitable means of fixation.
  • the printing ci­linder 5 has been provided, of which the diameter is conside­rably larger than that of the printing cilinder 5, depicted in fig. 1. Further it is shown, that the printing roller 18 is moved until it is adjacent the printing cilinder 5.
  • this embodiment comprises a shaft, exten­ding parallel to the axis of the printing cilinder 5, onto which a coil 31 of double-sided-adhesive foil has been provi­ded. At the upper side, this foil comprises a layer of pro­tective paper.
  • a cutting organ 33 On a shaft 32, also being provided parallel to the axis of the printing cilinder 5, a cutting organ 33 has been provided, which is movable along this shaft, and which can cut the length 34 of double-sided-adhesive foil leading from the coil 31 towards the printing cilinder 5.
  • an angle rotation sensor 35 has been provided, which is connected with the sig­nal generator 36.
  • the angle rotation sensor 35 serves to di­vide the circumference of the printing cilinder 5, which is of importance to determine the initial position of the prin­ting plate departing from an inital or zero-position of the printing cilinder. Further this is necessary when the prin­ ting plate 27 does not extend over the whole circumference and when several printing plates 27 have to be provided on the circumference.
  • the dimensioning of the cutting organ 33 and of the required angle of rotation of the printing cilinder 5 and thus of the pushing roller 18, which are sensed by the angle rotation sensor 36, is such, that the length of the stroke 34 of foil cut off suits exactly the circumference of the prin­ting cilinder 5. This avoids, that a part of the printing ci­linder is covered with a double layer of foil, or that a slit developes in the layer of foil. Subsequently the layer of co­vering paper can be removed from the foil, and the printing plate can be fixed by means of the method described with the help of fig. 1.
