Method for adjustment of sheet-shaped print substrate for printing machines, digital printers or copiers involves determining control functions and assigning print substrate to second transport unit

摘要

The method involves measurement of entry angle with first measuring unit (22). The first transport unit (15) takes the print substrate (1) through a first friction wheel (A) and second friction wheel (B), whereby two friction wheels are independent single drives. The first and second control functions are then determined. The first alignment of the print substrate is done with the first friction wheel. The first alignment of the print substrate with the first friction wheel takes place according to first control function and the second friction wheel according to second control function. The x-displacement is measured with a second measuring unit (24). The third and fourth control functions are determined. The second adjustment of the print substrate takes place with the first friction wheel according to the third control function and a second friction wheel according to fourth control function.
