Abstract: Divided shaft members constitute a cleaning fabric take-up shaft, and are secured at both ends by shaft member fixing means that is attached to a side plate. Shaft member fixing portions include a shaft end supporter, for supporting the end of the shaft member, and a plug that is fitted to a shaft receiving section. A wedge portion is provided, which runs across the center of the shaft end supporter and is projected linearly. When this wedge portion is inserted between the shaft members, the diameter of the shaft is increased. At this time, the winding of the cleansing fabric is performed. To dispose of the wound cleaning fabric, the shaft members are detached from the shaft member fixing portions and the wedge is extracted from the shaft members, so that the diameter is reduced, and the cleaning fabric is disengaged from the shaft members. As a result, the cleaning fabric take-up shaft can be removed from the cleaning fabric roll.

Abstract: In a web anti-wrap device for a web printing press, anti-wrap means is disposed between printing cylinders and a processing device which is positioned downstream of the printing cylinders in the printing press, to prevent a broken web from wrapping around the printing cylinders. Guide means is provided for guiding the anti-wrap means for movement between a first position in which the anti-wrap means fulfills the function to prevent the broken web from wrapping, and a second position in which the anti-wrap means is moved away from the first position to create a working space between the anti-wrap means and the printing cylinders or between the anti-wrap means and the processing device.

Abstract: There is disclosed a device for cleaning the cylinder of a printing press with a cleaning fabric. The device comprises a pad including a surface opposed to the cylinder. The cleaning fabric is directed between the surface of the pad and the cylinder, the surface of the pad being at least partially uneven. The device further comprises means for moving the surface of the pad toward the cylinder so that the cleaning fabric is pressed against the cylinder by the pad to clean the cylinder.

Abstract: There is disclosed an apparatus for identifying a page of printing plate or printed product. The apparatus comprises reading head means for reading out at least one of items in a local descriptive portion of the page of printing plate or printed product. The apparatus further comprises identifying means for identifying the page of printing plate or printed product in accordance with the read out data transmitted from the reading head means.

Abstract: A method of cleaning the outer surface of a cylinder by using a cleaning fabric intermittently fed from a supply, and engaged with and pressed against the outer surface of the cylinder. The method includes predetermining periods for each of which the cleaning fabric is engaged with the outer surface of the cylinder a time so that at least some of the periods are different in length from other periods in a cleaning cycle.

Abstract: A cylinder cleaning device for use with a cleaning fabric supply element having an outer surface comprises a frame and a receiving and supporting member connected to the frame for supporting the outer surface of the cleaning fabric supply element.

Abstract: A cleaning system employing a highly viscous cleaning agent. A highly viscous cleaning agent is placed on a strip of cleaning fabric whereby the strip of cleaning fabric is made functional for cleaning cylinders of printing presses. The strip of cleaning fabric is wrapped around the center piece. The strip of cleaning fabric may then be brought into contact with a cylinder to be cleaned in order to clean the cylinder. The highly viscous cleaning agent may be made by mixing a viscosity adding agent with a low volatility, organic compound solvent. Additionally, water or another additive may be mixed in for improved cleaning properties. The method of making the same is also discussed.

Abstract: The cylinder cleaning device according to the present invention is structured by independent components of a cleaning fabric supply element, a cleaning fabric take-up section, a cleaning fabric pressing section, and a brake section. The cleaning fabric supply element is formed by a flat box-form container. A shape-retaining member is provided on or in the vicinity of an inner surface of said container facing to a crease portion and/or a lateral portion of the cleaning fabric folded in multiplicity so as to act on the crease portion and/or the lateral portion of the cleaning fabric for retaining a folded shape of the cleaning fabric. The cleaning fabric supply element, the cleaning fabric take-up section, the brake section can desirably be arranged in a vacant space around the cylinder. Therefore, even in an existing machine the design for device structure is easy to design in a manner adapted for a vacant space without carrying out especial working.

Abstract: A dampening water circulation system achieves further lightweighting, easy maintenance and decreases a heat energy influencing the temperature of the dampening water. There are provide a dampening water supply pipe 50 and the dampening water pool bar 60 along the water fountain roller 20. The dampening water pool bar and the water fountain roller are arranged to maintain an aperture G of several mm to thereby form the water pool portion 70 between two members. The fed water can be kept in the dampening water pool portion to be applied on the water fountain roller. The dampening water pool portion is made small in size to minimize a time for the dampening water from the supply pipe 50 to the water fountain roller whereat the supplied water does not influenced by any foreign element, which can minimize the return water amount and is effective to decrease the cooling capacity for the used dampening water.

Abstract: An apparatus monitors the number of golf clubs in a golf bag during a round of golf game and warns a golfer if any of the golf clubs is missing. According to one preferred embodiment, a predetermined number of golf clubs is automatically detected, and the total number of the clubs is stored in a memory for a later comparison. During a round, the number of clubs is detected and compared to the stored initial number so as to determine if any club is missing. Upon determining that a club is missing, a warning is given to the golfer. This warning substantially reduces a risk of losing a club.

Abstract: In case an induction motor is controlled by a voltage type PWM inverter, reduction of an electromagnetic noise is made without enlarging a device.By providing an integrator 8 for obtaining an inverter phase angle by integrating an inverter frequency command and a carrier frequency modulator 9 for modulating so as to raise a frequency of a modulation signal for only a certain angle in the center of every 60 degrees of the phase angle, a magnetic flux vector can be brought closer to a locus of a circle so as to reduce the electromagnetic noise more than that of a conventional one.

Abstract: Ink remaining on an ink roller (R) for applying ink to a plate cylinder is softened by a solvent, and then a cleaning cloth (4) is moved intermittently or continuously in press-contact with the ink roller so that an oil absorptive layer of the cleaning cloth absorbs and hold the softened ink. The cleaning cloth which has absorbed the ink is sent to a cleaning cloth disposing section (8) to be cut off by a cutter (3), or to be taken up by a set length by a taking-up roll to be wasted together with the taking-up roll. The cleaning cloth at least comprises an oil absorptive layer and an oil impermeable layer, and has good softened ink absorptiveness and is free from the leakage of the absorbed ink. Especially the cleaning cloth having a non-flowback oil impermeable layer can perfectly hold the absorbed ink, and has good disposability.
