Abstract
A method for feeding sheets to a printing technology machine improves reliability of feeding sheets and reduces an acceleration time from a base speed to a production speed. The sheets are conveyed onto a feed table in shingled formation by a first drive and are individually and successively conveyed from the feed table to a first processing station of the machine by a second drive. The sheets are conveyed onto the feed table before an acceleration of the second drive to production speed is completed and the first drive is accelerated to the production speed when the processing station has reached the production speed.
Claims5
A method for feeding sheets to a printing technology machine, the method comprising the following steps:
- conveying the sheets in a conveying direction onto a feed table in shingled formation using a first drive;
- conveying the sheets individually and successively from the feed table to a first processing station of the machine using a second drive;
- and
- accelerating the drives from a base speed to a production speed as follows:
- conveying the sheets to the feed table before the second drive has reached the production speed;
- stopping the first drive as soon as the sheets on the feed table assume a predefined position in the conveying direction and are at a predefined distance from each other;
- and
- then accelerating the first drive to the production speed after the processing station has reached the production speed.
