Abstract: A die stamping device for cutting, scoring or creasing a pattern of shapes onto laminar material, comprises a die cylinder having a solid cylindrical core with a coating of setting material such as plastics in which are fitted cutting or scoring blades the radially outer surfaces of which define the pattern to be cut or creased onto laminar material passed in sheet or web form between the die cylinder and a smooth pressure cylinder, which may be provided with cooperating elements, such as resilient blocks or engraved recesses to cooperate with the scoring or creasing blades; the die cylinder is made by a process involving forming a pattern on the outer surface of the coating by photographic techniques, and then removing the coating from the solid cylindrical core to facilitate cutting out the openings to receive the blades.

Abstract: A rotary drive device for effecting, for example, displacement of a printing roller towards or away from a pressure roller in a printing press, is formed by a direct current or alternating current high speed motor coupled mechanically to a permanent magnet low speed motor. Fast movement is effected with the permanent magnet motor being pulled by the high speed motor, while slow movement with rapid braking is effected, at high torque, with the permanent magnet motor excited and pulling the other motor, to bring the printing roller gently into contact with the pressure roller.

Abstract: Apparatus for testing a printing or other roller for a printing machine has a framework in which the roller is supported in cooperation with a counter-pressure roller which is interchangeable in the framework to enable the cylinder to be tested before installation in a machine. A web is fed to the nip of the cylinder and the pressure roller over a table upon which the web may be braked by, for example, suction applied through the table. The test apparatus includes tools for treatment of the web, the treated web being withdrawn by a discharge conveyor which is driven at a greater speed than the peripheral speeds of the cylinder and the counter-pressure roller.

Abstract: A device for feeding or winding up a web to or from a web using machine such as a web printing machine or a painting, coating, spreading or laminating machine, comprises two lateral uprights carrying one or two pairs of arms which are turnable about substantially horizontal axes and which carry at their free ends means for mounting the ends of a core on which a roll of web is or is to be wound, one of the arms carrying a drive motor for driving the core to rotate to wind-up or feed off web from the roll; the arms are hollow box section elements and the motor is housed within the interior which can also be provided with a brake and with means for circulating cooling air.

Abstract: A web winding and cutting apparatus for mounting downstream of the final stage of a web handling machine such as a printing machine includes pressure rollers mounted upon pivoted arms and engageable with the final roller of the machine to draw the web from the final stage, so that a relatively low-torque motor can be employed to drive a core upon which a roll is round. A movable cutter blade may be associated with pivoted arms carrying joining rollers used for pressing the severed leading end portion of the web onto the core to be wound.

Abstract: A mounting for supporting a pair of cylinders, particularly for use in printing machines, in which the cylinders are adjustably arranged and kept at a given distance from each other, wherein a first cylinder of the pair of cylinders is supported at each end thereof by a resiliently deformable member, and that the second cylinder of the pair of cylinders is movable towards, and away from, the first cylinder by means of an adjusting support device which, in operation, is responsive to resilient deformations of the resiliently deformable member when such deformations exceed a predetermined value.
