Method and Apparatus for Handling Printed Sheet Material

METHOD AND APPARATUS FOR HANDLING PRINTED SHEET MATERIAL

A support cylinder for guiding freshly processed substrate material between printing units or at the delivery end of a printing press is provided with a low coefficient of friction, semi-conductive base covering for supporting and guiding the freshly processed substrate material without smearing the ink or causing indentations on the surface of the substrate. Radially projecting surface portions of the semi-conductive base covering define electrostatic precipitation points and reduce the surface area available for frictional engagement. The low friction and semi-conductive properties of the base covering permit free movement of the freshly processed substrate relative to the support cylinder surface. Electrostatic charges carried by the freshly processed substrate are discharged through the semi-conductive base covering into the support cylinder, thus eliminating electrostatic cling attraction between the freshly pro- cessed substrate and the support cylinder.

Base material processing apparatus and detection method

A base material processing apparatus includes first and second edge sensors and a displacement amount calculation part. The first edge sensor acquires a first detection result (R1) by detecting the position of an edge of a base material in a width direction at a first detection position. The second edge sensor acquires a second detection result (R2) by detecting the position of the edge of the base material at a second detection position. The displacement amount calculation part calculates the amount of displacement in the position of the base material in the transport direction or the amount of difference in the transporting speed of the base material on the basis of the first and second detection results (R1, R2). Thus, the amount of displacement in the position or the amount of difference in the transporting speed can be detected without depending on images such as register marks.

High speed digital printing system and method for continuous web

A high-speed digital printing system includes two unwinding machines for two input coils for a paper web, an input unwinding and splicing installation and a printing station and in which the input installation supplies, in turn, the printing station with the web of the two coils. The system also includes a splicing and rewinding installation with an output cutting and splicing equipment for an incoming web emerging from the printing station and two rewinding machines with two output coils. The output equipment feeds alternatively the rewinding machines with the incoming web by cutting and splicing of a web of the two output coils without stopping printing. An electronic controller switches the functionality of the output cutting and splicing equipment and of the rewinding machines with setting of the output coils as an operating coil and a waiting coil and, viceversa, as a waiting coil and an operating coil.
