Abstract
A printing device with friction drive for processing continuous paper. For this purpose, it contains a friction drive (8) comprising friction rollers, between which the recording substrate (A) is passed through, and a paper feed device (PZ). In the paper feed device (PZ), the recording substrate (A) is aligned in a web precentering device (3), is thereafter braked in the recording substrate transport direction, so that the recording substrate (A) assumes a predetermined position in the friction drive (8). After that, the recording substrate web is stabilized in a stabilization zone by stabilization rollers (9) and is fed via a festoon device (10) to the drive (8) of the printing unit (DA).
Claims11
A printing device for processing strip-shaped recording substrates, the printing device having a friction drive for transporting the strip-shaped recording substrate and a paper feed device for feeding the strip-shaped recording substrate to the friction drive, the paper feed device comprising:
- a web precentering device operable to align the strip-shaped recording substrate by forcible guidance on an aligning edge;
- a device operable to increase the tension in the strip-shaped recording substrate in a recording substrate transport direction past the web precentering device in such a manner that the strip-shaped recording substrate assumes a predetermined position in the friction drive;
- a web stabilization device stabilizing the recording substrate run in a stabilization zone positioned before the friction drive;
- and
- a mechanical strip accumulator for accumulating the recording substrate.
A method for feeding a strip-shaped recording substrate to a printing device which has a friction drive for transporting the strip-shaped recording substrate, the method comprising the following steps:
- aligning the strip-shaped recording substrate by forcible guidance on an aligning edge of a web precentering device;
- braking the strip-shaped recording substrate in the recording substrate transport direction after the web precentering device in such a manner that the strip-shaped recording substrate assumes a predetermined position in the friction drive;
- stabilizing the recording substrate run in a stabilization zone positioned before the friction drive.
