Abstract
The invention relates to a device for processing sheets and/or webs by means of a pair of driven rollers forming a gap, wherein the gearing connected to the rollers has, in terms of changes to the gap formed by the rollers, a fixed gearwheel and a second gearwheel which moves together with one of the rollers and interacts with the fixed gearwheel, and wherein the center-to-center distance of these two gearwheels remains constant irrespective of changes to the gap.
Claims4
A device for processing substrates (6) in the form of sheets and/or webs such as paper, cardboard, corrugated board or similar materials, comprising at least
- a working roller (1) that is rotatable about its axis (201), wherein the working roller (1) essentially extends transverse to a transport direction (200) of the substrate (6) to be processed,
- a mating roller (2) that is assigned to and interacts with the at least one working roller (1) and is rotatable about its axis (202), wherein the mating roller (2) essentially is oriented parallel to the at least one assigned working roller (1) and the at least one mating roller (2) forms a working gap (4), through which the substrate (6) to be processed is transported in the transport direction (200), together with the at least one assigned working roller (1), and wherein the substrate (6) is processed at least by the working roller (1) in said working gap,
- a drive with a motor and a gearing (30, 40), wherein the gearing (30, 40) produces a drive connection of the motor to the working roller (1) and to the mating roller (2),
- a first adjustment device (10) that is assigned to the at least one working roller (1) and/or the at least one mating roller (2), wherein the at least one first adjustment device (10) is connected to the at least one working roller (1) and/or the at least one mating roller (2) in such a way that the at least one first adjustment device (10) is suitable for adjusting the working gap (4) between the working roller (1) and the mating roller (2) to a predetermined dimension (210),
- a second adjustment device (20) that is assigned to the at least one working roller (1), wherein the second adjustment device (20) is connected to the working roller (1) in such a way that the at least one second adjustment device (20) is suitable for adjusting the phase position of the working roller (1) in relation to a physical and/or virtual main shaft of the device to a predetermined dimension, and
- at least one controllable adjustment drive (21) of the second adjustment device (20) and by an electronic control (7), wherein the at least one adjustment drive (21) and the at least one control (7) are connected to one another with the aid of at least one first data transmission means (71).
