Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce the cost of operation when adjusting and setting a feeder, to improve accuracy in the placement of signatures (7 to 9) onto a transport device, and to improve the quality of collating and stitching.SOLUTION: When the feeder of an saddle-stitch bookbinding machine is controlled, a point of time when a gripper is opened or a point of time when the gripper is closed is controlled by programming, and is steplessly adjusted depending on a format. Therefore, data about the size of a signature and the number of pages are input to a control device (18). From the data, an adjustment signal for a gripper adjustment element is formed.
