Abstract: A device (1) for patterning plane substrates (5) without a template includes at least one stationary printing station (2) which applies a substance to the substrate and the substrate (5) passes the station along a conveying path. Each printing station (2) is equipped with a dye-spraying head (21) mounted on a carrying device (22). The spraying head carrying device (22) is part of a movable unit (3) which can be displaced to a side in a direction transverse to the conveying direction (B) of the substrate (5) out of a first operating position (I), adopted in the patterning region of the substrate (5), into a second set-up and service position (II), which partially releases the substrate (5).

Abstract: In a jet nozzle for applying dyes or the like in a pattern or a precise dosing of liquids, onto a material the nozzle mouth piece (6) is closed by a needle (7, 18, 28) actuated by a magnetic system (10, 20, 11, 21). To this effect the needle (7, 18, 28) passes the magnetic system (10, 20, 11, 21) and is connected to another diaphragm (26) which defines an upper chamber (29) containing a dye and which is connected to the second chamber (19) containing a dye, for guiding the needle (7, 18, 28) within the space defined by the diaphragms (16, 26) diaphragm discs (33, 34) being provided.
