Abstract: In a device for inking a pitted cylinder, and for ensuring a regular inking, a pressing roller is placed within a seal tight chamber formed between doctor blades provided for laminating ink within the seal tight chamber.

Abstract: The exit cylinder of a first unit is connected to the entrance cylinder of a second unit for making a deformable parallelogram, and at least the exit and entrance cylinders of each unit are respectively connected to displacement mechanisms.

Abstract: This invention relates to a plastic substrate production process, the production device for such a substrate, and the use of the process for the production of integrated circuit boards. The plastic substrate production process is characterized in that it comprises the following steps: unwinding and straightening of a continuous strip of plastic which is slightly larger in dimension than one of the dimensions of the board; printing, at at least one printing station, of a series of printing patterns and of printed markings; driving of the strip at a regulated printing speed; detection of the difference in speed; cutting by a press of the strip at positions defined by the printed markings; and regulation of the printing speed as a function of the difference between the printing speed and the driving speed.

Abstract: A positioning and splicing device for paper rolls having at least one carriage arranged to be movable along guides and having an upright on one side provided with slide members for guiding a second carriage that is axially movable along the upright. The second carriage is provided with a spindle for engaging a roll. The roll is raised by a movement of the spindle protruding from the roll and the carriage is moved into engagement in a rotary coupling element that is fixedly mounted, so that the spindle is supported at both ends when the sheet is un-wound from the roll.

Abstract: The common base of the comb-shaped clearing device is made of a shaft. Screws are provided for blocking pairs of parallel arms on a shaft in variable positions as a function of a longitudinal position of a series of points on the cutting cylinder (2). The two arms of each pair, which are symmetrical with respect to a symmetry vertical plane, have inner faces turned toward one another and formed in such a manner as to define therebetween an interval having a width which increases from front to rear.
