  • This transfer cylinder is assigned a impression cylinder, around which the web to be printed is guided. Transfer cylinders and impression cylinders run continuously at a constant speed, so that such printing machines have a very high throughput.
  • the transfer cylinder is designed so that its printing-technically effective peripheral surface can be adapted to different print image lengths without much effort. This can be achieved, for example, in offset printing in that the lateral surface of the transfer cylinder is formed by a rubber blanket, which can be exchanged without difficulty and / or easily adapted to the respective print image length.
  • the transfer cylinders of this group are generally designed so that their lateral surface extends over less than 360 °, so that special precautions must be taken to apply the printed images without spacing or only with a small repeat distance on the web. To do this, the web must be positioned after each work cycle for the following work cycle, so as to enable printing with small distances between the individual print images.
  • EP 0018291 an embodiment in which the printing unit has a drive roller which operates independently of the actual printing unit.
  • the transfer cylinder is formed fully cylindrical, but also for the positioning of the web requires an additional drive means.

  • the web may be expedient to cool the web after it has passed the UV lamp. This can be done in a simple manner already during the passage of the printing cylinder, which may be designed for this purpose as a cooling roller. In any case, if possible, the procedure should be such that the web does not undergo any heating due to the UV irradiation, which could lead to unacceptable stretching or shrinkage of the web. This is particularly important if the web is made of plastic and / or several printing stations are arranged one behind the other, through which the web, as usual in multi-color printing, is passed.
  • Fig. 1 illustrated printing machine (10) is used for printing web-like material (12), which withdrawn from a first roller (14) and in the direction indicated by the arrow (16) general transport direction by four in this transport direction (16) successively arranged printing stations I - IV is guided, which have substantially the same structure.

  • the portion of lesser thickness (52) does not come into contact with the web (12) guided over the printing cylinder (26) during rotation of the blanket cylinder (22) and is thus ineffective in printing technology.
  • the adaptation of the blanket cylinder (22) to the respective print image length is carried out by appropriate selection or adjustment of the blanket (50).
  • the blanket (50) When changing the print image, for example, of a length according to the embodiment of Figs. 3A to 3C to a shorter length according to the embodiment of Fig. 4

  • the portion (52) of lesser thickness of the blanket is arranged in the direction of rotation (54) behind the cutout (48) following it.
  • Fig. 3B shows an intermediate stage during the printing process, in the course of which a printed image is applied to the web (12) which is approximately the length of the circumference of the blanket cylinder (22) minus the peripheral portion which corresponds to the cutout (48).
  • the transfer of the respective print image is completed and the blanket (50) out of contact with the web (14), that is about the position according to Fig. 3C
  • the controlled according to a program drive the printing cylinder is controlled such that initially the rotation in the direction of arrow (56) delayed and after reaching the value zero, a rotation of the printing cylinder (26) in the opposite direction, ie in the direction of the arrow (58) takes place, so that the web (12), which is out of contact with the blanket cylinder during this phase, between the impression cylinder (26) and the guide roller (30) runs in the opposite direction.

  • This rotational speed of the printing cylinder (26) in the direction of the arrow (56) is reached at the latest by the time in which the blanket (50) of the cylinder (22) for applying the next printed image according to Fig. 3A comes back in contact with the train (12).
  • the above-described sequence of rotational movements of the printing cylinder (26) correspond to the linear movements of the compensation carriage (34).
  • the carriage (34) controlled with respect to its movements is moved with the two freely rotatable rollers (30, 32) in the direction of the arrow (38) so as to assist at the speed V 1 continuously fed web (12) to shorten the distance between the compensation roller (30) and the guide roller (42), whereby additional sheet material in the area between the compensation roller (30) and counter-pressure roller (26) is made available to an increase in the web speed in the region between the roller (30) and the impression cylinder (26) to eg 35 m / min comes and thus the resulting speed of the web (12) of the printing speed, ie the peripheral speed of the two cylinders (18 and 26) equivalent.
  • the movement of the compensation slide in the direction of the arrow (38) also takes place during the printing process at a constant speed V 3 .
  • the carriage (34) in accordance with the now beginning delay of the rotation of the printing cylinder (26) in the direction of the arrow (56 ) is moved in the direction of the arrow (38) at a corresponding decreasing speed until the speed of the web (12) between deflection roller (42) and pressure cylinder (26) becomes smaller than the speed V 1 with which the path of the compensation roller (30) is supplied.
  • the carriage (34) is displaced in the direction of the arrow (36), the speed of the carriage (34) in this direction decreasing the rotational speed of the printing cylinder (26) in the direction of the arrow (56) and then reversing the rotation correspondingly increases in the direction of the arrow (58).
  • the execution of the next cycle presupposes that the rotation of the printing cylinder 26 in the direction of the arrow 58 and the corresponding counter-movement of the web 12 are brought to zero by a correspondingly programmed deceleration, and then the impression cylinder is returned in the direction of of the arrow (56) is accelerated to the printing speed with simultaneous entrainment of the web (12), wherein the compensation carriage (34) performs corresponding movements - during the deceleration phase a movement with decreasing speed in the direction of the arrow (36) and during the subsequent acceleration in Counter direction (56) a movement in the direction of the arrow (38). The latter occurs when the speed of the web (12) is greater than the speed V 1 at which the web is fed.
  • This movement in the direction of the arrow (38) takes place, as already mentioned, at a substantially constant speed as soon as the web (12) has been brought to the speed required for printing, which corresponds to the circumferential speed of blanket cylinder (22) and impression cylinder (26) ,
  • impression cylinder (26) and compensation slide (34) have the function, the web (12) position so that, in spite of the presence of the cutout (48) and optionally the portion of lesser thickness (52) of the blanket (50), the printed images to be applied sequentially on the web (12) are in close contact with each other or optionally with a small clearance can be applied to each other, which is substantially smaller than the path length in radians, during which the blanket cylinder (22) or the blanket (50) out of contact with the web (12).

  • the period during which the blanket cylinder (22) is not in contact with the web corresponds to a longer circumferential distance than in one embodiment according to the Figs. 3A to 3C since the contact between the blanket cylinder (22) and the web (12) is terminated at the moment in which the step (60) ( Fig. 4 ) separating the two regions of different thickness of the blanket (50), passes the location of the printing cylinder (26) at which the blanket is normally in contact with the web (12).
  • a constant duration of a working cycle irrespective of the length of the printed image to be applied, that is, a constant rotational speed of the blanket cylinder independent of the print image length, has the consequence that the speed V 1 at which the web (12) is introduced into the respective printing station is higher at a greater length of the printed image than the smaller length of the same, since the supplied per unit time web length is greater for a longer print image than for a shorter print image.
  • the angle at which the web (14) wraps around the impression cylinder (26) should not fall below a certain minimum size, so as to slip avoid and achieve the highest possible accuracy of movement of the web (14) relative to the blanket cylinder (22).
  • the size of the required wrap angle which is about 180 ° in the illustrated embodiments, can be determined at any time by appropriate experiments.
  • the maintenance of a constant web tension is essential. Consequently, it is possible to proceed in such a way that the web tension is preferably measured continuously and, when deviating from a desired value, the drive of the compensation carriage is influenced, for example, by small control steps in such a way that the setpoint voltage is restored. Influencing the speed of the compensation carriage as a function of the web tension could superimpose the program according to which the movement of the carriage is controlled. However, it is very small in size, and will normally be substantially the same in terms of the speed and direction of movement of the web with the parameters provided by the program.
  • the blanket cylinder (22) can also be moved so that the web (12) is provided with markings, which are detected by at least one photocell (62), and the drive for the Pressure cylinder (26) is controlled or regulated in response to the position defined by the registration mark position of the web.
  • This may optionally be done in addition to a drive controlling program.
  • the influencing of the rotational speed of the blanket cylinder caused by such control steps is so small that the deviation possibly caused thereby from the predetermined constant rotational speed of the blanket cylinder with respect to the duration of the working cycle is negligible.
  • a device (64) is assigned to the printing cylinder (26) ( Fig. 2 ), by means of which the printed web is exposed to irradiation by UV light. This ensures that the ink is substantially dry when the web (12) from the printing cylinder (26) expires. In this way, it is possible to deflect the web (12) in the direction shortly behind the driving pressure cylinder (26) via the compensation roller (32) to obtain the shortest possible railway lines.
  • the printing cylinder (26) is provided with at least one cooling channel (66) through which a cooling medium, for example water, flows.
  • a cooling medium for example water
  • the cooling of the web avoids unacceptable shrinkage and / or stretching caused by heating of the web, which could also affect the accuracy with which the web is aligned with the blanket cylinder.
  • the cooling of the web in order to avoid undue heating may be particularly important if, as in the embodiment according to Fig. 1 ,
  • the web is passed through several successively arranged printing stations, each of which is provided with a UV lamp.
  • the cooling may also be effected by other means, for example by a cooling air flow being blown against the printed web.
  • this may also be a partial print image in the sense that a plurality of partial print images are applied to the web at the same location in order to produce an overall print image as is the case with multi-color printing, for example.
  • the invention is explained above essentially in connection with the offset method, the invention is also applicable to other printing and decoration methods.
  • the invention can also be used in high-pressure printing, for example flexographic printing and gravure printing and in rotary screen printing, but also in embossing, in particular hot embossing, without the above enumeration being complete.
  • the web to be decorated is to be positioned in one phase of a work cycle so that the successive applied print images have no or only a small distance from each other, the adjustment to different image lengths preferably by appropriate adjustment of the feed speed V 1 .
  • the transfer cylinder regardless of the print image length in its pressure-technically effective lateral surface have a constant diameter.
