(54) DRYER FOR PRINTED OR SUPPLIED PAINTING PLATES TO PRINTING OR SIMILAR MACHINES The invention concerns a dryer for sealed or supported coatings installed directly after a web-fed rotary printing press or coater. The sealed or carrier coating of the web is dried in the dryer with beams, such as infrared or ultraviolet, and is cooled in a cooling unit installed behind the dryer. Drying of the sealed or carrier-coated fabric in known dryers is carried out by infrared or ultraviolet radiation sources such that the fabric, the output from the last printed image, enters the dryer through the inlet gap, is mixed past the radiators and through the outlet gap into the cooling unit. In order to avoid stamping out a fresh print. The canvas hp and moving from the printing section to the cooling unit are free to hang. Depending on the type of the print and the printing ink, the web is led off by the duplex cylinder to a certain wrap angle, so it lags behind the corresponding cylinder. Thus, the web cannot enter the dryer at a constant level of movement, and, depending on the angle of wrap, is correspondingly higher or lower than this level. Such a phenomenon may periodically alternate. As a result, the web oscillates along the nagfleshpo, pyaicule of the plane of its movement. It is necessary to choose the height of the input gap corresponding to the maximum maximum expected amplitude of the oscillation of the web. 1 Iesa is relative. large ECKNOE clearance uncontrolled large amount of infrared or ultraviolet rays can go outside. In addition, a large gap height adversely affects the directional airflow generated by the airfoil op sufficient cooling of the radiators inside the hangers, since an uncontrolledly large volume of air is also sucked through the inlet gap, which in turn requires an increase in the power of the air blower. These deficiencies generally impair the efficiency of the dryers to such an extent that sometimes impressing marks are not excluded. No less significant is the risk of irradiation by the ultraviolet rays emanating from the operating personnel. Known dryer for printing inks in which before the input and output gaps are installed, respectively, caps, the so-called tunnels. Each ; .of them equipped with labyrinth lyotas. Due to these caps and rigidly attached labyrinth sheets, the output of the rays is somewhat reduced, but for such dryers, due to the adhesion of the web to the double-sided printing cylinder, the height of the entrance gap of the cap must also correspond to the maximum amplitude of web oscillations. . Thus, in this case, the controlless intake of excess air equally has its effect, as a result of which the intentional efficiency of this bearing is significantly reduced, which negatively affects the quality of the stamp, especially the print printed on the last printing section. . The purpose of the invention is to optimize the efficiency of the dryer in such a way as to eliminate the deterioration in quality, in particular the impression of the last printing section of the machine, located directly in front of the dryer. The invention is based on the task of making the inlet gap and the inlet cap in such a way that, while maintaining the height of the inlet gap due to the operating mode, it does not allow the inherent effects on the deliberate mode of air flow inside the dryer, thereby on its efficiency. The goal is achieved by the fact that the entrance gap is formed by guiding guards installed one by one respectively above and below the canvas around the axis, located on the entrance cap and located transversely to the direction of movement of the Cloth with the possibility of turning and fixing them, and turning

tubes selectively divided into or together with regulated pressure air. The 3 edges of the guide plates are directed from the axis towards the movement of the web. These two guides, which are adjustable and fixed relative to the web, make it possible to measure the height of the entrance gap in accordance with the expected and dependent on the type of ink on the angle of the circumference of the double sided cylinder and the amplitude of oscillation of the web. Accordingly, it is possible to adjust the minimum height of the entrance gap without fear of touching the web with the guide plates in the event that the web oscillates and the quality of the impression is affected. Due to the fact that the guide plates can be rotated separately independently FRIEND from each other, it is not difficult to adjust the middle of the gap with a deviation from the plane of movement of the web. In addition, the subject invention provides for the exit of only a small fraction of the rays from the dryer. By adjusting the inlet gap to the lowest possible height, the flow of air in the dryer in the deliberate volume required for cooling the emitters is ensured. In this case, a definable amount of air is sucked through the inlet gap. dryers. A further advantage of discharging the guide plates is by bending them in such a way that the convexity of the bend faces the plane of movement of the web. The air drawn in by the blower holds the web between the two guiding flaps in a constant state. The airbag formed between the guide plates on both sides of the web allows the choice of an extremely small height of the entrance gap, since it additionally strongly damps the web oscillations in a vertical direction to its surface. Finally, it is possible to install between the axes of rotation of the guide plates and the corresponding upper or lower surface of the blade in the direction of its movement in front of the directional plates of the rotary nozzles. This also provides for the formation between the guide plates and the surface of the canvas The possibility of setting the input clearance between the guide plates to the minimum height is even more supported. FIG. Figure 1 shows the dryer in direct connection with the preceding or subsequent working sections, section; in fig. 2 - input clearance in real; ki with trapezoidal arrangement on the right side of the shields; in fig. 3 shows a dryer gap with curved guide plates; FIG. 4 is another schematic set out of the input clearance of the dryer; FIG. 5 - dryer side view. The dryer 1 in the direction of the blade travels in front with the printing section 2 and behind the cooling ai regatta 3. The canvas 4 of the printed material moves between the upper and lower offset cylinders 5 and 6 into the dryer 1 and is suspended in the cooling unit 3. The dryer consists from the upper part 7 and the lower part 8, in which the radiators 9 are located, separated in the plane of movement of the web 10 from each other. In front of the inlet gap 11 of the dryer 1, a split, closed rio sided and attached to the upper part 7 and to the lower part 8 of the inlet cap 12 is placed on the top of the plane of the movement of the blade 1O. In both parts of the inlet cap 12 there are pivotally mounted guide plates 14 each independent axis 13. The guide plates are located nozzle-like with respect to the plane of the web and to each other and form an effective in-kind gap 15. To enable the control plates 14 to be adjusted in accordance with the movement of the inclination from the straight plane to the web, which is caused by the adhesion of the web 4 to one of both offset cylinders 5 or 6 at a certain angle of girth, Hai of the inlet cap 12 are located in front of each clamping groove 16 in each adjustment groove 16 clamping bolts 17. The expected maximum inclination of the incoming web is 4 the size of the opening of the entrance gap 15 in the folding inlet cap 12 is determined. On the outer edge of one of the side walls 18 of the entrance cap 12 above and below the plane of movement of the web 10 a scale 19 is provided, with the help of which The blade 4 is tilted from the plane of movement of the blade 10, according to which it is possible to adjust the angle of the guide pins 14 with the clamping bolt 17. these: guards 14 in marinating from the vice. The installation of guides 14 can be checked through window 21, whereby ultraviolet rays are absorbed. The predominant addition (the solution according to the invention is to install on both sides of the web 4 directly in front of the flares of the 14 nozzle tubes 22. These tubes are selectively filled separately or together with controlled pressure air. The vibrations of the web are transmitted by an air pressure cushion , with the help of a clamping bolt 17, VOILABLE to adjust the yawak guiding flaps 14 to a truly effective entrance gap 15 up to a maximum height.
