Abstract: Ink feeding circuit device for a raster drawing machine comprising an ink jet printing head 1 moving in x and y direction over the drawing plane 20 of the drawing machine 10 and comprising a feed circuit including an ink supply reservoir 2 connected with the ink jet printing head 1 by a conduit 31 which communicates with a gas damper 9.

Abstract: The flat bed raster drawing machine is controlled automatically, includes a flat table to bear a flexible material, such as paper, fixed guides on which a carriage moves perpendicular to the lengthwise axis of the flexible material between the aforementioned guides, and a second carriage bearing the pin printer array type head that moves over the preceding one, in the direction of the lengthwise axis of the paper. The paper is moved in a controlled manner on the table parallel to its lengthwise axis.

Abstract: An aerial system is formed by a main closed circuit with diverse stations on both sides of the circuit, along which the production units move hanging on carriages having means of identification, control cards for the status and the main circuit. The main circuit includes a series of identical strips, articulated on primary supports that have a holding part and a trigger to support the carriages with hanging lightweight components. The carriages have a cylindrical holder on the top to hang the primary supports on the wheel triggers. The carriages enter the lowest point at the stations, move up to the main circuit by means of a hoist mechanism which includes a carriage presence detector at the lowest point.
