摘要:
A bladder (218) for bringing and engaging a cleaning cloth (105) into contact with a blanket cylinder (100). The bladder (218) has a molded (extruded or machined) shape optimized to, when inflated, provide a contact surface (500) elevated above the remainder of the bladder (218). When the bladder (218) is not inflated, the contact surface (500) or central portion remains elevated above the reminder. In addition, the device has improved contact characteristics, providing significant improvement in the consistency of contact surface with less sensitivity to pressure fluctuations between the cylinder (100) and the bladder (218) over prior art.
摘要:
A system and method of a combination and sequencing of a first cleaner (120) around a blanket cylinder (114), a second cleaner (140) around one of the rollers in an ink form roller assembly (110), and a fluid applicator (160) around another one of the rollers in the ink form roller assembly effectively clean the press rollers and the blanker cylinder used in a printing machine.
摘要:
A cleaning system for a printing press using pre-soaked, reduced volume of air in cleaning fabric. The system includes a cleaning fabric treated to reduce the amount of air volume the cleaning fabric contains. The cleaning fabric is saturated to functional equilibrium with a low volatility organic compound solvent. The cleaning fabric is wrapped around an elongated core (11) to form a fabric roll (13). The saturated, wrapped fabric roll may be used to clean a cylinder of a printing press. The saturated, wrapped fabric roll may be inserted in a sealable sleeve (15), the sealable sleeve being in contact with the fabric roll and then sealed, thus permitting transporting and storage of the system until use without detrimentally affecting the cleaning ability of the fabric. A method for making the system is also disclosed.
摘要:
A cleaning system employing a highly viscous cleaning agent. A highly viscous cleaning agent (20) is placed on a strip of cleaning fabric (13) 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 (11). 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.
摘要:
An apparatus (130) is disclosed for facilitating handling of sheets in a sheet-fed printing press as they are passed between a first cylinder and a second cylinder. The apparatus (130) comprises an outer surface of the first cylinder (100) having a plurality of grooves (400;520) extending substantially along a circumference of the first cylinder (100), the plurality of grooves (400;520) having at least a first edge (530) and a second edge (531) in the outer surface of the first cylinder (100) defining outer peripheries of the plurality of grooves (400;520), the first and second edges (530,531) being spaced along a long axis of the first cylinder (100). The apparatus comprises further a pliable membrane (500) arranged on the first cylinder (100) and sealingly attached to the outer surface of the first cylinder (100) at least at the outer peripheries of the plurality of grooves (400;520), wherein a plurality of sealed cavities (610) for receiving a quantity of fluid are formed by the plurality of grooves (400;520) and by portions of the pliable membrane (500) which sealingly enclose the plurality of grooves (400;520) for cushioning sheets of printed material (120;121) as they are passed between the first and second cylinders (100;105). A method of forming such an apparatus (130) is also disclosed.
摘要:
A novel apparatus and method of a take-up shaft (20) used in the cleaning of a cylinder of a printing press (100). The take-up shaft (20) includes features that allow the securing of a cleaning fabric (52) from a supply roll (50) without the need to physically fix or mount the fabric to the supply roll (50) with screws or other fasteners that could cause the fabric to tear.
