摘要： An apparatus for facilitating handling of sheets in a sheet-fed printing press (155) comprising a matte (130) that is mountable on a cylinder (100). The matte has at least one inflatable pocket (125) for cushioning sheets of printable material as they are passed between two cylinders of the press. At least one valve (135) communicates with the inflatable pocket and controls the quantity of fluid in the inflatable pocket. A number of inflatable pockets can be utilized to provide increased control over various sheet sizes. Further control may be obtained by including a number of valves to independently operate each of the inflatable pockets. Ease of installation and removal is accomplished by incorporated mounting holes along the long axis of the matte. Alternatively, the matte may be arranged on the cylinder by adhesively bonding (tape or glue) the matte to the surface of the cylinder or by arranging the matte on the cylinder with Velcro fasteners. A number of mattes may be combined to form a compound matte resulting in greater resolution and precision. Methods for making as well as using the apparatus are also disclosed.

摘要： A non-contact sheet handling system (100) includes a first valve (110) controlling air flow to a manifold (104) and a second valve (112) controlling air flow from the manifold to an air pan (106). A non-contact plate (107) having venturis (202) covers the air pan. In an alternate embodiment, the system includes a diffuser (302a) that diffuses air flow in the air pan. A method of using a non-contact sheet handling system includes adjusting a first and second valve (112, 114) to set air flow to a first and second area, respectively, of the system and adjusting a third valve (110) to set air flow to the first and second valves.

摘要： A system and method for preventing a broken printing web (30) from wrapping about or otherwise fouling the blanket cylinders of printing press units. The system and method includes a web tensioning device located downstream of the printing press units (10A-10D) for maintaining tension upon a broken web (30) and pulling the web from the printing press units. The device includes a plurality of web disturbance detectors (15) for detecting a wave, ripple or other disturbance indicative of a web break. A pair of anti-wrap rollers (50) located above and below the web are engaged upon detection of a web break to engage the web between them to exert tension onto the web and pull it from the printing units. The anti-wrap rollers are rotated at a surface speed nominally greater than the surface speed of the printing rolls (5). The anti-wrap rollers (50) include a plurality of opposed peak and valley portions which enable them to interlock and grip the web along a line of contact. The system and method also includes a flow bar system to reduce false detections of a web break . A blow-down bar is also used to force air, or some other fluid, downward on a broken web so as to harmlessly force the broken web to the ground as it exits the web tensioning device. A series of sensors (340) which projects two beams in the form of a crossing pattern are utilized to more rapidly and accurately detect a web break.
