  • Patent number: 4838159
    Abstract: Described is a lifting device for cylindrical templates in printing machines, with an inking tube extending through each cylindrical template, the lifting device travelling along a rail running parallel to the direction of the cylindrical template and along a rail travelling in a direction normal thereto and which can be releasably connected to the inking tube. The lifting device is constructed in the form of a hydraulically or pneumatically operated telescopic arm, always in the vertical position, which carries a tong-like gripper (2) for releasable connection with the inking tube (3).

  • Patent number: 4833748
    Abstract: In a method and device for the application of foamed or non-foamed flowable substances upon a substrate, where the quantity of the substance to be applied in function of the surface units to be coated is preselected, the flow rate of the material dispenser to the applicator is controlled by a control element and the quality of application is insured by measurements of the application pressure.

  • Patent number: 4649816
    Abstract: A screen-printing or roller-printing machine in which magnetic force generates the printing force against a web, has a support member, e.g. a magnet beam or worktable, which provides the attractive force for a pressure member printing the pattern on the web. The support member has limited bending resistance, i.e. can flex readily and is supported from below by a separate structure thermally insulated therefrom so that bowing of the support member does not occur.

  • Patent number: 4606502
    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.

  • Patent number: 4586014
    Abstract: In an electromagnetic beam respectively a beam- or carrier-like worktable for pressure coating and other processing machines operating with magnetic contact pressure, at least one pole end of the magnet cores of the electromagnet is connected in a heatproof manner by means of a magnet-connecting bridge with a support profile symmetric to the plane of the magnet core axes.

  • Patent number: 4561354
    Abstract: A screen printing apparatus utilizes a number of screen printing heads disposed along a transport path for the fabric; each of the heads moves upwardly on a respective carrier so as to be tiltable by a pneumatic cylinder with respect to the carrier which is vertically displaceable in common with the other carriers by the displacement of a common element connecting wedges together. The carriers each have extensions provided with rollers which ride upon ramp surfaces of the respective wedges. The vertical displacement compensates for changes in diameter of the screen printing patterns and for changes in thicknesses of the webs processed.

  • Patent number: 4550681
    Abstract: A flowable material, such as an impregnant, a dyestuff or a bonding agent, is applied to the surface of a relatively moving substrate by way of a channel system formed in a plate surface, in a stack of slabs or in a solid block. This channel system has a branched structure extending from an entrance port to a multiplicity of exit ports, the branch channels becoming progressively more numerous and correspondingly narrower toward these exit ports. The latter, extending in a row transverse to the direction of motion across the full width of the substrate surface, open onto that surface directly or through one or more discharge nozzles in the form of a slot or a multiplicity of orifices, possibly with interposition of a gear pump whose toothed cylinders are floatingly received in part-cylindrical cutouts of the body slightly exceeding their diameter.

  • Patent number: 4542692
    Abstract: A screen printing installation of the type in which a magnetic member below to be printed attracts an ink applying element against a pattern and a fabric on a support, in which the support is tensioned between a pair of members on an inner frame completely separate from an outer frame in which the upper pattern carrying the carriage is guided. The lower carriage carrying the magnetic member and the upper carriage can be coupled for joint movement through the gaps between the support surface and the longitudinal elements of the outer frame.

  • Patent number: 4524688
    Abstract: An apparatus for printing a pattern of a flat horizontal screen on an underlying substrate comprises a wiper assembly mounted on a carriage above the screen and an electromagnet beneath the screen reciprocable along the latter jointly with the carriage. A cradle limitedly pivotable on the carriage about a horizontal axis extends across the screen and supports, via adjustable holders, a working wiper and a distributing wiper on opposite sides of its pivotal axis. The working wiper, which may be a blade or a roller, directly overlies the electromagnet and is magnetizable and/or accompanied by a magnetizable mass whereby energization of the electromagnet attracts the side of the cradle bearing that wiper to press it against the screen for forcing dyestuff therethrough onto the substrate, this side trailing during a printing stroke.

  • Patent number: 4090443
    Abstract: A device for treating a web or the like adapted for screen printing including a magnetizable wiping roller or squeegee mounted on a working carriage, a printer's blanket carrying the web, a magnetic beam disposed below the printer's blanket, and rails rollably supporting the magnetic beam. The magnetizable wiping roller is urged towards the web through movement of the working carriage in the longitudinal direction of the printers blanket, and guided thereover by the magnetic beam in the course of printing on the web. The web is stationary during treatment. An electric motor is provided for moving the magnetic beam and the motor drives at least one drive wheel engageable with the rails for moving the beam. Speed and position of the wiping roller is determined by a sensor arrangement responsive to deviation of the working carriage from the magnetic beam path.
