<p>PROBLEM TO BE SOLVED: To provide a mark detector in a bag-making filling machine in which a relationship between a position and a mark in a width direction of a film along which a line sensor detects the mark, can be set with a good efficiency according to nature of meander of the film and so on.SOLUTION: A mark detector in a bag-making filling machine in which relation of aberration between a proper position (L1, L2, L3) of a mark pre-stored in a width direction of a film and a position of a current mark (17) can be confirmed on a display unit (15). When a correct operation for the relation of aberration of both of the positions is performed via a setting unit (12), a control unit can correct corresponding position relation for finding out marks of standard pixel data having pre-stored mark information and evaluation pixel data obtained by a line sensor during operation in the width direction of the film.</p> |
