摘要： Disclosed is a correction system for an alignment film printing plate, including: a roller and a printing plate mounted as a sleeve outside of the roller, wherein a first end portion of the printing plate is provided thereon with a plurality of columns of buckle groups, and a second end portion of the printing plate is provided thereon with a plurality of columns of slot groups engaged with the buckle groups. The correction system for the alignment film printing plate further includes an image controller used for measuring a deviation value between an actual position and a preset position for printing of an alignment film on a substrate. The correcting system of the alignment film printing plate has a simple structure and is capable of realizing different stretching degrees of an alignment film pattern at different positions on the printing plate, so as to improve a correction effect of the printing plate. As a result, deviation can be reduced between an actual position and a preset position for printing of the alignment film on the substrate, without significant increase in costs.

摘要： A lock-up assembly (20) for securing a printing plate (22) on a plate cylinder (10) includes a rotatable lock bar (32) and a spring biased linkage mechanism (36). The linkage mechanism (36) has a first over-center condition in which it rotates the lock bar (32) toward a locked position, and has a second over-center condition in which it rotates the lock bar (32) toward an unlocked position. A movable blocking member (82) blocks the linkage mechanism (36) from switching to the second over-center condition under the influence of centrifugal force when the cylinder (10) is rotating during a printing operation. A hand held tool (40) engages the linkage mechanism (36) to switch it between the first and second over-center conditions upon manual manipulation of the tool (40). The tool (40) also engages the blocking member (82) to move the blocking member (82) from the first position to the second position when the tool (40) is moved into engagement with the linkage mechanism ( 36).

摘要： A printing plate holding device for an offset duplicator. The device includes a base slidably positioned on one side of a grooved portion of a plate cylinder of the duplicator. A clamp plate is secured to the base and a clamp lever is attached to the clamp plate. A latch is loosely secured to a pin attached to the clamp lever and connected to a spring to provide a plate clamping force upon the clamp plate. A guide plate and a plate release preventing plate are attached to an outer longitudinal side of the base. An axial displacement control device is positioned at one longitudinal end of the cylinder while a circumferential displacement control device is positioned at the other longitudinal end thereof.

摘要： An arrangement for the accurately positioned quick-action clamping and tensioning of printing plates on a plate cylinder (1). Clamping tools (14) are disposed in frame walls (2) and, after appropriate positioning of the plate cylinder, are engageable in coupling sleeves (12) on camshafts (4.3, 5.3) of front and rear tensioning bars (4, 5) by the application of pressure medium (15, 16, 17, 18). Clamping and unclamping is then effected by turning the clamping tools (14) via levers (20) and compressed air cylinders (23). A compressed air motor (25) is disposed in the cylinder gap (3) for tensioning purposes.

摘要： A sheet to be clamped includes registration holes at its edges. The leading and trailing ends of the sheet are superimposed, then positioned and clamped with respect to a cylinder by means of a clamping bar. The sheet is tensioned by use of an adjustable tensioner rod. Vernier-type scales on the sheet and cylinder aid in measuring and setting the desired tension. A longitudinal edge of the sheet is located by pins suitably located on the cylinder. In alternative embodiments, the clamping bar and tensioner rod are combined in a unit, or the clamping bar is formed in split sections to receive the sheet therebetween.
