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: A raster-type drawing machine (plotter), automatically controlled from a controller, which consists in a tubular structure of rigid elements that join and support the elements of feeding, printing, advancement, and collection of sheet material. The sheet-paper-collection and feeding modules are formed by a set of rollers and disks that support the sheet material. The controlled one-way movement of the sheet material in the direction X is carried out through two rollers whose length is much smaller than the width of the material to be printed. The machine includes guides fixed to its structure through which a carriage set carrying the print heads moves according to axis Y.

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.
