Washing device for cleaning a cylinder of a printing machine includes a brush roller formed with bristles and rotatably driven about an axis, the brush roller cooperatively engaging the cylinder, a device for feeding washing fluid to the bristles for self-cleaning the bristles, and a deflection element disposed in a rotational region of the bristles, fixed in position relative to the brush roller and extending along the length of the brush roller, the bristles yieldingly brushing against the deflection element as the brush roller is rotated so as to be bent temporarily and subsequently returned to a straight extended position thereof, the deflection element being formed as a distributor pipe connected to the feeding devices and having outlet openings formed therein for directing the washing fluid radially towards the axis of the brush roller.
摘要:
A method of washing an offset printing press having a plate cylinder, a rubber blanket cylinder, an impression cylinder, an inking unit a paper thickness compensator and a damping unit. The inking unit and the damping unit include, respectively, inking rollers and damping solution applicator rollers. The offset printing press also includes a washing apparatus. The washing apparatus, when in the wash mode, is placed in engagement with the rubber blanket cylinder of the printing press by control apparatus. Also, in the wash mode, the impression cylinder is engaged with or disengaged from the rubber blanket cylinder by a paper thickness compensator. The usual purpose of the paper thickness compensator is to compensate for the thickness of the stock in running-on mode but is employed herein also to effectuate washing of various rollers and/or cylinders of the printing press.
摘要:
A printing press having an inking unit and a wetting unit, which cooperate with a printing form by means of an inking roller and a wetting roller, having a control device for moving the wetting roller into an engagement or disengagement position with respect to the printing form. To expedite simple handling in the application of another substance onto the printing form, the wetting roller is supplied with the another substance by an apparatus provided therefore and moved into its engagement position with respect to the printing form by a control apparatus.
摘要:
Device for feeding a printing plate to a plate cylinder of at least one printing unit of a printing press, the plate cylinder having a clamping device formed with clamping surfaces for clamping a leading edge of the printing plate therein, includes at least one element for holding and guiding the printing plate, the one element being a readily rotatable roller having an outer cylindrical surface which, in a plate-changing position, is disposed substantially tangentially to a straight line disposed between the roller and the one printing unit, the straight line extending parallel to the clamping surfaces of the clamping device, passing between the clamping surfaces and leaving the one printing unit in an upwardly inclined direction.
摘要:
Device for axially reciprocating an inking-unit roller of a rotary printing machine having a fixed shaft and a frictionally driven roller shell including a pair of rings formed with opposing circular roller tracks disposed within the inking-unit roller and repectively secured to the shaft and the roller shell, one of the rings being skewed in axial direction with respect to the other of the rings, and a ball rollably received in both of the roller tracks and actuatable for effecting a step-down in speed of the axial reciprocatory motion of the inking-unit roller.
