Method according to claim 11, wherein by means of the detection means the programmable control means ascertains the position of the marking on the textile and transmits this information to the pretreatment means, the pretreatment means, based on the transmitted information and according to the print job clearly defined beforehand, applies the pretreatment area as intended.

13. Method according to claim 11, wherein the programmable control means receives a print job containing printing and image data that were sent by a user and by means of the printing means the textile is printed with a corresponding printed image.

14. Method according to claim 1, wherein the detection means has a readout means and/or a sensor means, by means of which the marking on the textile can be read out by the programmable control means.

Description

(1) The invention will be explained further hereinafter by way of the accompanying drawing, wherein shows:

(2) FIG. 1 a schematic illustration of the device according to the invention for pretreating and printing textile surfaces.

(3) FIG. 1 shows a device 10 for printing textile surfaces. A textile 20 to be printed is provided with a printing face 25 on a pallet 22, which is in a set-up position, in which the pallet 22 can be loaded with the textile 20. By means of the movement means 23 the textile 20 on the pallet 22 is supported in a movable manner along a guide rail 24 and can be delivered successively to the individual means of the device 10. Starting from the set-up position, in a movement direction of the pallet 22 a detection means 30 is initially arranged, by means of which the textile 20, more particularly a marking 21 on the textile, can be detected by a programmable control means 31. The programmable control means 31 is connected to all means of the device 10. The information determined by the detection means 30 with regard to the textile 20 can be assigned by means of the programmable control means 31 to a clearly defined print job. By means of an input terminal on the device 10 or via a long-distance communication connection the print job can be transmitted by the user to the programmable control means 31. The printing and image data thus transmitted are converted by the programmable control means 31 into a control of the individual means of the device 10 according to orders.

(4) In the movement direction of the pallet 22, starting from the set-up position of the pallet 22, a pretreatment means 40 designed in a direction transverse to the movement direction of the pallet 22 is provided behind the detection means 30. The pallet 22 can be passed underneath the pretreatment means 40, with a pretreatment fluid being applied onto the textile 20. The pretreatment means 40 has a plurality of nozzles 41 that are designed along the pretreatment means 40 and extend on this over the entire width of the textile 20 on the pallet 22 in the direction transverse to the movement direction of the pallet 22. Through individual actuation, in particular by opening and closing the nozzles 41 during application of the pretreatment fluid onto the textile, the programmable control means 31 controls the pretreatment means 40 in order to apply an individual pretreatment area 26 onto the textile 20, in which the printed image can be provided according to order. The said pretreatment area is illustrated schematically on the textile 20 in FIG. 1. In this, those areas of the printing face of the textile can in particular be excluded from pretreatment which are not printed with a printed image. Control of the pretreatment means 40 takes place according to the information of the print job concerning the textile to be printed which was transmitted by the detection means 30 to the programmable control means 31 or is stored in the programmable control means 31.

(5) In the movement direction of the pallet 22, after the pretreatment means 40 a dryer 50 is arranged which extends in an elongate manner along the guide rail 24 and by means of which the applied pretreatment fluid on the textile 20 can be dried and/or treated thermally.

(6) In the movement direction of the pallet 22, after the dryer 50 the printing means 60 is arranged which has at least one print head 61 that is supported in an alterable manner in a direction transverse to the movement direction of the pallet. The print head, which can be a digital ink jet print head in particular, is movable over the entire width of the textile 20, thereby even enabling printing in a marginal area of the textile 20. The printing means 60 with the print head 61 is controlled by the programmable control means 31 in order to provide the printed image according to order in the pretreated area on the textile. For removal the textile can be moved back into a first set-up position in front of the detection means 30. In doing so, the pallet with the printed textile passes once more at least the dryer 50 which, in a second drying step, can dry or thermally treat the printing ink applied to the textile to ensure a particularly good bonding of the printing ink to the textile surface.
