摘要： PROBLEM TO BE SOLVED: To provide a converting apparatus capable of controlling the smooth adjustment of the transverse register of a reference roll with high accuracy. SOLUTION: In the converting apparatus having a reference roll 1 such as a plate cylinder or the like, bearing parts on the man side and gear side of the reference roll 1 are supported on one roll stand 6 and a movement adjusting mechanism for moving the reference roll 1 in an axial direction is provided on the roll stand. The effect of the sliding of the bearing on the man side and a housing is removed and the effect of the roll assembling accuracy to the control accuracy of register adjustment is reduced to a large extent and the highly accurate smooth adjustment of the transverse register of the reference roll can be controlled.

摘要： PROBLEM TO BE SOLVED: To obtain a printing press for perfectly executing printing in an end region of a cantilevered impression cylinder. SOLUTION: A printing press comprises at least one counterpressure cylinder, at least one printing roller cantilevered at one end in a rolling stand, and at least one inking roller or screen roller of an inking system cantilevered at one end in the rolling stand, where bearings of the printing roller and screen roller travel, in guide mechanisms, relative to the counterpressure cylinder. In order to ensure that the printing executed by means of the end region of the cantilevered impression cylinder is also perfect, a plate 12 is coupled to the rolling stand, which plate 12 is provided with bearings 10, 11 in order to accommodate the journals 8, 9 of the free ends of the printing and screen rollers 2, 3. In this regard, the plate 12 can be swung to either a retracted position, in which the cantilevered rollers 2, 3 are freely accessible, or to an operating position, where the journals 8, 9 of the free ends of the rollers 2, 3 are carried by the plate 12.

摘要： PURPOSE: To obtain an inexpensive cylinder, shorten assembling period, and reduce service costs by centering a cylinder on the end surface side of an inner race in the frame of bearing and releasably connecting the cylinder to the inner race. CONSTITUTION: A roller bearing in the bore of a frame 2 comprises an outer race 3 eccentrically formed, an inner race 5 centrally provided, and rolling bodies 4 disposed between the races 3, 5 to support a cylinder 1. The inner race 5 is provided in an intermediate chamber of both side frames so as to protrude toward an end surface 11 of the cylinder to receive a centering part 8 on the periphery of a pin end 12 by means of its centering area 8'. The race 5 further has an end surface adjacent to the cylinder 1 and the end surface is formed into a flat surface 7. A flat surface 7' is disposed on the cylinder shoulder 13 so as to oppose the surface 7. The adjoining surfaces 7, 7' form a connection between the cylinder 1 and the inner race 5 of bearing through connection members 6, e.g. screws, in releasably connected relationship.

摘要： PURPOSE: To find out a roller bearing for press cylinder, which has high rigidity to compensate aligning error of a hole in the machine frame and flexure sometimes generated. CONSTITUTION: Roller bearing rows are place between three rail rings 2.1, 3.1, 6. So the unified eccentric intermediate ring 6 forms a bearing unit together with an outer ring 3.1 via a cylindrical roller bearing row 10.2 and a ball bearing row 9.2 and together with an inner ring 2.1 via a cylindrical roller bearing 10.1 and a ball bearing row or a cross roller bearing row 9.3. A spring 19 is placed between the inner ring 2.1 and the trunk shoulder 7.1 and an adjusting nut 14, an adjusting screw, or the like is placed between the eccentric intermediate ring 6 and the journal 4.

摘要： PURPOSE: To obtain a printing machine to achieve beautiful print even with an impression cylinder which has not a perfect cylindricality by measuring the roundness error of the circumference of the impression cylinder and by moving the cylinder within a guide unit in accordance with the remembered roundness error. CONSTITUTION: When the impression cylinder 4 is rotated slowly in a retainer 6, a straight edge 8 is maintained in the condition contacting with the surface of the impression cylinder due to the pressure applied by a pneumatic piston- cylinder unit 7. The position of the straight edge 8 is detected by a tracer-roller 10 fitted in the housing through a bracket 11. The deviation of the tracer-roller 10 is transmitted to a transducer 13, which memorizes the value of the deviation in a cassette. The tape with the memory is treated by a computer, signals are sent to a servomotor or a step-motor, and the roundness error is compensated according to the signals.

摘要： PURPOSE: To minimize the slip motion between a plate cylinder and a form roller by forming the form roller so as to have a diameter in a specific ratio with respect to that of the plate cylinder and applying a layer comprising an ink receptive elastic material to the form roller and specifying the thickness and hardness of the layer and applying the form roller to the plate cylinder at a time of operation to bring the same into contact with the plate cylinder in a specific length peripheral direction. CONSTITUTION: A form roller has a diameter of about 99% with respect to that of a plate cylinder 5 and the hard core 15 of the form roller is coated with a layer 16 comprising an ink receptive elastic material and the thickness of this layer is 2-3% of the diameter of the form roller and has Shore hardness of 60-70 deg.. A shaft 14 is supported on a side wall 3 by a regulable eccentric bearing 17 and also supported on opposedly positioned side walls in the same system. The form roller 12 can be applied to the plate cylinder 5 during operation by using the eccentric bearing 17 and is brought into contact with the plate cylinder 5 in the peripheral direction over a length of about 7-9 mm. The slip motion between the plate cylinder 5 and the form roller 12 is sufficiently avoided and a wash mark or a contaminant is not generated in printed matter.

摘要： PURPOSE:To miniaturize the anti-drive side chuck mechanism for the automatic attaching and detaching device for a gravure print roll by a method in which a spindle with an electrified supporter is supported by a cylinder device in a movable and turnable manner and a movable droplets-preventive cap is provided to the outside of the spindle. CONSTITUTION:In an anti-drive side chuck device as an automatic attaching and detaching device for a hollow roll R, the other end of a spindle 2 whose top is attached with an electrifying supporter 15 is attached to the piston 1b of a cylinder device 1 in a turnable manner and moved toward the axial direction by the supply of pressure oil from a supply hole 1d, and the roll R is supported in a turnable manner and also in an electricity-suppliable manner. A droplets- preventive cap 4 composed of a non-electrifying material is fitted on the tip of the spindle 2 to cover the electrifying supporter, and it is pressed on the roll R by introduction of pressure oil to the cylinder chamber 6. These functions are easily attained by a fluid controlling and the whole size of the device is compactedly miniaturized.
