    摘要： Cutter and creaser apparatus that cuts and creases sheets and thereafter strips the cutout portions from the sheet includes a drive mechanism that is capable of either intermittently stopping the sheet for the cutting and creasing operations or varying the speed of the sheet as it is conveyed through the cutter and creaser apparatus. The drive mechanism includes a drive shaft driven at constant velocity by suitable drive means. A speed control shaft is mounted in parallel spaced relation to the main drive shaft and is connected thereto by a pair of meshing gears to that the speed control shaft rotates at the same angular velocity as the drive shaft. A sun gear of a planetary gear assembly is connected to the drive shaft for rotation therewith and meshes with a planet gear that, in turn, meshes with the internal toothed portion of the ring gear. The external toothed portion of the ring gear meshes with a drive gear for the press sheet conveyor shaft on which a pair of drive sprockets are mounted in spaced relation to each other. A lever is pivotally connected to the drive shaft intermediate its end portions and has one end portion connected to the planet gear. The other end portion has a cam follower mounted thereon that is maintained in abutting relation with the cam surface of a cam secured to and rotatable with the speed control shaft. The cam upon rotation pivots the lever and moves the planet gear. The angular velocity of displacement of the planet gear through the lever determines the relative velocity of the sheet conveyor. Another embodiment includes bevel gear arrangements to selectively decrease and increase the speed of the conveyor mechanism.

    摘要： A nonrotatable tumbler cam mechanism is positioned coaxially with the transfer cylinder on the operator''s side of the press and is movable axially thereto. A cam actuated device is provided on the transfer cylinder for tumbling the perfector and two color grippers inwardly to transfer the trailing edge of the sheet from the perfector grippers to the two color grippers. A cam follower on the cam actuated device is actuated by the tumbler cam mechanism. A pair of gripper actuating cams are coaxially and nonrotatably mounted relative to the transfer cylinder on the drive side of the press. One of the pair of cams, referred to as a two color cam, is arranged to open and close the two color grippers for two color printing and the other of the pair of cams is arranged to open and close the perfector grippers and the two color grippers for perfector printing. The pair of cams, i.e., the two color cam and perfector cam, are secured to each other and movable axially relative to the transfer cylinder. The perfector grippers and two color grippers have a cam follower associated therewith that is actuated by either the two color cam or the perfector cam. The two color and perfector cams are connected through a lever mechanism to an actuator device that is arranged to move the pair of cams axially relative to the transfer cylinder. The tumbler is also connected to the actuator device located on an exterior portion of the press so that the actuator device simultaneously moves the pair of gripper actuating cams and the tumbler cam to adjust the transfer cylinder for either the two color or perfector printing.

    摘要： A WEB FED PERFECTING PRESS FOR PRINTING OFFSET IMAGES OF DIFFERENT SIZE ON THE PRINTED WEB. BOTH THE TOP AND BOTTOM PLATE CYLINDERS ARE JOURNALED IN A PRESS FRAME FOR ROTATION ABOUT FIXED AXES. THE TOP AND BOTTOM BLANKET CYLINDERS ARE JOURNALED IN AUXILIARY FRAMES THAT ARE SUPPORTED BY THE MAIN FRAME. THE AUXILIARY FRAMES ARE ADJUSTABLE HORIZONTALLY ON THE MAIN FRAME TO MOVE THE BLANKET CYLINDERS TOWARD AND AWAY FROM EACH OTHER AND TOWARD AND AWAY FROM THE FIXED PLATE CYLINDERS. BOTH OF THE BLANKET CYLINDERS ARE MOUNTED IN ECCENTRIC BEARINGS FOR VERTICAL ADJUSTMENT WITHIN THE AUXILIARY FRAMES SO THAT THE BLANKET CYLINDERS ARE ALSO ADJUSTABLE VERTICALLY RELATIVE TO EACH OTHER. THE PLATE AND BLANKET CYLINDERS ARE ARRANGED TO HAVE ANNULAR PLATES OF DIFFERENT CIRCUMFERENCES MOUNTED THEREON WITH DIFFERENT SIZED ANNULAR FILLER SHIMS BETWEEN THE CYLINDERS AND THE PLATES. THE VARIOUS SIZED PLATES AND FILLER SHIMS PROVIDE DIFFERENT LENGTHS FOR THE PRINTED OFFSET IMAGES ON THE PRINTED WEB. THE DRIVE GEARING AND BEARERS FOR THE PAIRS OF PLATE AND BLANKET CYLINDERS INCLUDE IDLER GEARS AND IDLER BEARERS SUITABLY MOUNTED TO DRIVE THE PLATE AND BLANKET CYLINDERS OF DIFFERENT DIAMETERS. TO CHANGE THE DIAMETER OF THE PLATE AND BLANKET

    CYLINDERS, THE ANNULAR PLATES AND ANNULAR SHIMS ARE REMOVED FROM THE CYLINDERS AND OTHER PREFERABLY PREREGISTERED PLATES AND ANNULAR SHIMS ARE POSITIONED ON THE CYLINDERS WITHIN THE PRESS TO CHANGE THE CIRCUMFERENTIAL DIMENSION OF THE PLATE AND BLANKET CYLINDERS. THE AUXILIARY FRAMES ARE ADJUSTED HORIZONTALLY AND THE BLANKET CYLINERS ARE ADJUSTED VERTICALLY TO MOVE THE PERIPHERY OF THE BLANKET CYLINDERS INTO ABUTTING RELATION WITH THE PLATE CYLINDERS AND INTO ABUTTING RELATION WITH EACH OTHER FOR PERFECTING PRINTING ON BOTH SIDES OF THE WEB.
