Abstract
A device for lacquering or coating a substrate is disclosed. The device includes a substrate plate configured to accommodate said substrate, and one or more suction points connected to, and extending upwardly from, the substrate plate. The one or more suction points may be configured to provide a vacuum to said substrate.
Claims17
A device for lacquering or coating a substrate, the device comprising:
- a substrate plate configured to accommodate said substrate, the substrate plate configured for rotational movement;
- a plurality of suction points connected to, and extending upwardly from, the substrate plate, wherein the suction point is configured to provide a vacuum to said substrate, the plurality of suctions points including four suction points;
- at least one upwardly terminating channel disposed and milled in a top surface of the substrate plate, the channel being connected to the suction point;
- and
- a closure piece provided on the substrate plate for closing or sealing off at least one upwardly terminating channel;
- wherein each suction point includes a respective tube extending upwardly from a top surface of the substrate plate;
- each tube provides spacing between a surface of said substrate and the substrate plate;
- the plurality of suction points each include a flexible surface;
- each respective tube has a foot defining an end of the tube via which each respective suction point is fastened to the substrate plate;
- a length of the respective tube determines a spacing of said substrate from a surface of the substrate plate;
- and each respective suction point is connected to a partial vacuum source via a respective milled channel in the substrate plate.

A device for lacquering or coating a substrate, the device comprising:
- a substrate plate configured to accommodate said substrate, the substrate plate configured for rotational movement;
- a plurality of suction points connected to, and extending upwardly from, the substrate plate for providing a vacuum to said substrate and the only contact points for said substrate, wherein each suction point includes a tube extending upwardly from a surface of the substrate plate to provide spacing between said substrate and the substrate plate, and each suction point also includes a flexible surface configured for contact with said substrate;
- a plurality of upwardly terminating channels disposed and milled in a top surface of the substrate plate, the plurality of channels connecting the suction points, respectively, to at least a partial vacuum source;
- and
- a plurality of discrete closure pieces inserted into respective upwardly terminating channels of the plurality of upwardly terminating channels for closing or sealing off the plurality of upwardly terminating channels, respectively:
- wherein each tube has a foot defining an end of the tube via which each respective suction point is fastened to the substrate plate;
- and each tube is disposed entirely above the substrate plate;
- and the length of each tube determines a spacing of said substrate from a surface of the substrate plate.
