    The invention relates to a system for printing textile webs, the system comprising a particular impact-free printing station, a pretreatment device for applying at least one pre-treatment substance and a conveyor for continuously conveying the textile web from the pretreatment device to the non-printing station.
    An impact-free printing station is understood to mean a printer which transfers the dyes to the textile web without a mechanical stop. So there is no fixed artwork or printing form needed, so that the print image continuously - preferably via a computer - can be changed. Such printing methods are also known under the two English expressions "Non Impact Printing" and "Direct Digital Printing".
    It is known that the quality of printed textiles can be increased by pretreating the textiles with special chemical substances before printing them. For example, it is advantageous in the course of this pretreatment to improve the absorption capacity for the colored pigments.
    Patent specifications JP 8-311782 (A), WO 02/18703 A1 and EP 1 577 101 B1 describe systems for printing textile webs, these systems also providing devices for applying pretreatment substances in addition to a printing device. The application is carried out by means of a dip bath, a spray nozzle or an applicator roll. These application methods have several serious disadvantages: it is neither possible to dose the application quantity nor to control the penetration depth of the pretreatment substance. As a result, the print quality depends very much on the quality of the goods. It is often attempted to compensate for this disadvantage by applying rather too large an amount of the pretreatment substance and then evaporating the excess by means of a drying device. However, this procedure requires a lot of energy and delays the production process. In addition, part of the
    Pretreatment substance unnecessarily consumed and possibly even released in the form of pollutants.
    Object of the present invention is to avoid the disadvantages described above and compared to the prior art more economical and ecologically advantageous system for printing textile webs, which also also ensures a higher process stability specify.
    This object is achieved in that the pretreatment device comprises a roller, at least one magnet and at least one of the magnet to the roller down attracted doctor.
    The application of the at least one pretreatment substance takes place with the aid of this pretreatment device in such a way that the textile web is guided over the roller and the doctor blade attracted by the magnet to the roller passes at one point of the roller, with the textile web being literally squeezed together at this point. If the doctor is now also in contact with the pre-treatment substance, it is transferred to the textile web. It is easily conceivable that several such doctor blade systems can be arranged around the roller and that in this way more than one pre-treatment substance can be applied to the textile web.
    It should be noted that the term "application" is not meant to be merely superficial application. Rather, it may also be desired that the pre-treatment substance penetrates into the textile to a desired depth or completely penetrates the textile. This depends, e.g. from the quality of the goods. The penetration depth of the pretreatment substance in the described pretreatment device can be controlled automatically by the distance of the doctor blade from the roll and thus by the degree of pinching. Against this background, it is understandable that the pretreatment device according to the invention enables an advantageous metering of the application quantity of the at least one pretreatment substance.
    An advantageous embodiment of the inventive system for printing textile webs is that the roller via a drive, preferably via a gear drive, can be driven. This has the advantage that, in addition to fulfilling the main function in connection with the application of the at least one pretreatment substance, the roller also serves to further transport the textile web.
    With regard to a compact design of the pretreatment device, it is advantageous if the roller is formed as a hollow shaft and the magnet is arranged in this case in the hollow shaft.
    It has proven particularly advantageous if the at least one magnet is an electromagnet. In this case, it is very easy to control the magnetic force and thus the degree of pinching via the current. Depending on the dimensions of the electromagnet or depending on the number of electromagnets used, it may be advantageous in some embodiments if the at least one electromagnet can be cooled via a cooling device. It may be e.g. to act a water or air cooling.
    Another embodiment is characterized in that doctor blades with different surface structures are available. In this case, the application quantity of the at least one pretreatment substance can also be metered in via the choice of a specific surface structure, in addition to the always provided possibility of the variable distance of the doctor blade to the roller.
    Preferably, the plant for printing textile webs according to the invention comprises a winding device for unwinding the textile web from a product bale. In this way, the textile web can be continuously fed to the system. It may be desired that the rotational speed of the goods bale is controlled by a control device, since the textile web would be handled at a constant speed of rotation of the goods bale by the changing in the course of unwinding radius of the goods bale 4 different speed. The control device can be technically realized, for example via a rotational angle measuring device, wherein the rotation angle measuring device, for example, consists of a (eg pneumatically) biased and rotatably mounted in the middle pendulum, the pendulum comprises two pulleys, over which the textile web is guided Depending on unwinding - so that tension - the textile web adjusts itself to a different angle of rotation of the pendulum. If this angle of rotation is measured and compared with a predetermined value, and finally, depending on the size of the deviation of the angle of rotation from the predetermined value, the rotational speed of the goods bale changed so can control the unwinding speed of the textile web in this way.
    In further preferred embodiments, a preferably controllable deflection device for length compensation of the textile web and / or a positioning device for lateral positioning of the textile web are also integrated into the conveying device for conveying the textile web continuously from the pretreatment device to the non-stop printing station. Both measures serve to supply the textile web in a controlled manner to the printing station.
    Advantageously, the transport of the textile web by the non-stop printing station by means of a transport device. This transport device may be technically e.g. be realized in a simple manner by means of an endless conveyor belt, which runs over two guide rollers, wherein at least one of the two guide rollers is driven.
    If, in special embodiments of the inventive plant for printing textile webs, a repeating device for the repetitive feeding of the textile web to the non-impact printing station is desired, this may be technically technically e.g. by a roller arranged on a slide - whereby the slide can be driven by a drive - can be realized. The advantage of such a repetitive feed is that the unwinding of the textile web and the application of the at least one pre-treatment substance can be carried out continuously, despite the printing processes which each take a certain period of time. The *. *. * *. * *
    Repetition thus converts a continuous into a repetitive production process.
    Advantageously, the non-impact printing station comprises an ink-jet printhead, which preferably can also be moved by a drive transversely to the textile web, so that textile webs can be printed whose width extends beyond the width of the inkjet printhead. It has proven to be particularly advantageous if the inkjet printhead has a plurality, preferably eight, color units. For a high printing speed, it is also advantageous if the color units each comprise a plurality, preferably eight, nozzle units, the nozzle units are also arranged in a plurality, preferably in two mutually offset rows and / or in each case a plurality of nozzles, preferably each several hundred nozzles.
    Further details and advantages of the present invention will be explained in more detail below with reference to the exemplary embodiments with reference to the exemplary embodiments illustrated in the drawings. Showing:

    In Fig. 1, a preferred embodiment of the system 1 according to the invention for printing textile webs 5 is shown schematically. It should be noted that only the details essential to the basic understanding have been considered. The system 1 comprises from left to right: a winding device 4 for unwinding the textile web 5 from a bale of goods 2, wherein the winding device 4 a frame 3 for holding the goods bale 2 and a drive unit (in the illustration for the most part of the bales 2 covered ), with the aid of which the goods bale can be rotated, has a Drehwinkeimessvorrichtung 6, which is part of a control device for controlling the unwinding speed of the textile web 5 in the manner described above, a transfer point 7, whose function is the textile web of the pretreatment device eighth supply for the application of at least one pretreatment substance 16 and the operator of the system at the same time (eg for maintenance purposes) to allow access to the pretreatment device 8, the operation of the pretreatment device 8 is explained in more detail with reference to FIGS. 2 and 3, a preferably controllable deflection device 9 for Length compensation of the textile web 5, wherein an essential part of the deflection is a preferably weighted and movable guide roller 10, which is used to increase the deflection, the textile web 5 travels in the deflection, as needed to enlarge or reduce, a positioning device 11 for lateral positioning of the textile web 5, which consists in the embodiment shown essentially of a plurality of guide rollers, a repeater 13 for generating a repetitive feed of the textile web 5 to the non-impact printing station 15 in the form of a carriage arranged on a carriage, the carriage is driven by a drive and the Roller simultaneously serves as a pressure and deflection roller, a transport device 12 for transporting the textile web 5 through the non-stop printing station 15, wherein the transport device - as already described above - here essentially from an endless conveyor belt 14th , which runs over two guide rollers, wherein at least one of the two guide rollers is driven, and finally • ·· »

    Following its printing, the textile web 5 can be further processed further steps, such as. be fed to a drying. It should also be noted that the textile web 5 passes through such a plant 1 typically at a speed of 4 to 5 m / min.
    Figures 2 and 3 serve to illustrate preferred embodiments of the main part of the pre-treatment device 8 for the application of at least one pre-treatment substance 16, again-as in Figure 1-only the details essential to the basic understanding being taken into account. The two figures show two different cross-sectional planes of the pretreatment device 8, wherein the two cross-sectional planes are rotated relative to each other by 90 °.
    In the embodiment shown in Fig. 2, the textile web 5 is fed via a guide roller 20 of the roller 19 and then passes the point at which the magnet 19 to the roller 19 attracted blade 22 - here in the form of a Rolfrakel - is. In the illustrated case, the roller 19 is designed as a drivable hollow shaft and it is in the interior of the hollow shaft arranged magnets to an electromagnet, which consists of a current-carrying coil 18 and a magnetic core 17. The roller 19 is preferably made of aluminum or stainless steel - that is made of a non-magnetic material. On the other hand, the roller blade 22 is made of a magnetic material so that it can be attracted to the roller 19 by the electromagnet. The roller blade 22 is rotatably mounted within a guide device 21, which allows a variable distance of the roller blade 22 to the roller 19. The fact that the textile web 5 moves or the roller 19 performs a rotational movement and the roller 19, the textile web 5 and the roller blade 22 are frictionally in contact with each other, and the roller blade 22 performs a rotational movement. If the roller blade 22 is now partially submerged in the pre-treatment substance 16, then ♦ * δ becomes due to the rotational movement of the Roilrake! 22 continuously transferred a portion of the pretreatment substance 16 to the textile web 5 and penetrates - depending on the distance roller blade 22 to the roller 19 - to a desired penetration depth in the textile. The pre-treatment substance 16 is located in a trough 23 with an inlet 24.
    As already stated, FIG. 3 shows a further cross-sectional plane of the main part of a preferred embodiment of the pretreatment device 8. In this illustration, in turn, which is also here designed as a drivable hollow shaft roller 19 - to see. In this case, the drive via a gear drive, wherein the gears 28 of the right and left arranged on the hollow shaft gears can be seen. Inside the hollow shaft, a number of electromagnets (each comprising a current-carrying coil 18 and a magnetic core 17) are arranged. It can be seen that the magnetic cores 17 of the electromagnet down - so in the direction of the doctor blade 22 (not shown) - are made widened. As a result, an advantageous lateral "expansion" of the magnetic field is achieved. The hollow shaft is mounted on a support structure 27, which is rigidly connected to a stable (only partially shown) frame 25, rotatably supported by bearings 16. The electromagnets are attached to the support structure 27. In the embodiment shown here, the electromagnets with the aid of cooling air (indicated schematically by the arrows) can be cooled. In order to enable the necessary air flow path, the support structure 27 is formed at least partially hollow in the interior.
    Fig. 4 serves to illustrate the essential features of the non-impact printing station 15 in a preferred embodiment. Again, only the details essential for basic understanding were considered. In particular, the housing of the printhead has been omitted. It is a schematic representation in plan view. On display is a part of the textile web 5, which is transported by means of the endless conveyor belt 14 of the transport device 12 through the printing station 15. In the printing station 15, the textile web 5 is printed by means of a print head - here in the form of an ink jet print head, which can be moved transversely to the textile web 5 via a drive (not shown) and in this case has eight color units 29, each of the color units 29 being eight Nozzle units 30 The nozzle units 30 are arranged in two staggered rows and each comprise several hundred nozzles.
