摘要:
A sheet behavior monitor for a sheet processor includes: a folding machine processing a sheet; and a camera (30) taking an image once for each signature (Wb) folded by the folding machine. The camera (30) takes every image at a folding machine rotation phase different from that of the image immediately before taken.

A sheet abnormality detection apparatus includes a plurality of abutting members (112,142,236) which move upon coming into contact with at least one of sheets conveyed to overlap while being shifted from each other in a convey direction and an object attached to a sheet. The plurality of abutting members (112,142,236) are disposed side by side in a direction perpendicular to a sheet convey direction. The apparatus also includes an abnormality detection unit which detects a sheet abnormality on the basis of a relative positional shift among the plurality of abutting members (112,142,236). A sheet abnormality detection method is also disclosed.
摘要:
The present invention provides a printing system with an apparatus for defect detection comprising a sensing unit for sensing a surface geometry or topology of a sheet and for generating data representative of that surface geometry or topology, a processor device for processing the data to detect and classify deformations, and a controller for controlling further progress of the sheet along the transport path of the printing system in dependence upon the deformations detected and classified by the processor device. Furthermore, the invention provides a corresponding method of detecting defects in a printing system.

Bei einer Vorrichtung zum seitlichen Ausrichten von Bogen (9) ist es vorgesehen, diesen während der Seitenausrichtung zur Bogenstabilisierung mittels einer Andrückrolle (22; 23) zu führen, die der jeweiligen Ziehschiene (17; 18) gegenüberliegend angeordnet ist, vorzugsweise im Bereich einer zweiten Ziehschiene (18; 17). Die Andrückrolle (22; 23) ist gleichzeitig mit einer Mehrfachbogenkontrolle ausgestattet.
