ABSTRACT:
A web cutting position control system capable of cutting a web having a print pattern thereon in such a manner as to match the print pattern without limiting the mounting position of a synchronizing mark detecting means for detecting synchronizing marks on the web is disclosed. A counter for counting the rotational pulses, for example, of a cutting cylinder for cutting the web is provided so as to compare the pulse count at the time of synchronizing mark detection with the reference value representing a value at the moment when the web and the cutting cylinder are in normal relative positions, and to control the relative positions of the web and the cutting cylinder to the normal relative positions by controlling the movement of a compensating roller until the two values become equal to each other.
