Folding apparatus of a web-fed printing press including a conveyor belt monitoring device

摘要

A folding apparatus ( 30 ) having at least one conveyor belt ( 10 ) which is used to convey signatures ( 64 ) at least on a section of a path ( 66, 68 ) of the signatures ( 64 ) through the folding apparatus ( 30 ). The folding apparatus ( 30 ) features at least one monitoring device ( 12 ) with which the conveyor belt ( 10 ) is associated. The monitoring device ( 12 ) contains a detector ( 20 ) for radiation ( 22 ) scattered from at least a part ( 24 ) of the conveyor belt ( 10 ). The condition of the conveyor belt ( 10 ) can be determined and classified in an advantageous manner so that the machine operator can receive a signal for timely replacement so as to avoid an unexpected breakage of the conveyor belt ( 10 ).
