Abstract
A method for controlling a feeder of a gathering-stitching machine reduces the operating effort when setting the feeder, increases reliability when laying folded sheets on a transport device and improves quality during collating and stitching. Opening and closing times of grippers are regulated under program control, continuously and as a function of format when controlling the feeder of the gathering-stitching machine. Data relating to the dimensions and to the number of pages of the folded sheets is thus entered into a control device, from which data actuating signals for actuating elements of the grippers are generated.
Claims9
A method for controlling a feeder of a gathering-stitching machine, the method comprising the following steps:
- separating folded sheets one after another from a stack of a magazine using at least one gripper;
- opening and closing the at least one gripper using actuating signals from a control device;
- generating the actuating signals for opening and closing the at least one gripper from data relating to dimensions and number of pages of the folded sheets;
- and
- using a fold width dimension for setting a gripper opening angle of the at least one gripper.
