Abstract
An assembly comprises a device for producing a corrugated board web laminated on one side comprising a fluting device for fluting a first material web and a pressing device for pressing the glued corrugated web and a second material web against one another. The assembly comprises a first transverse position detecting device, upstream the fluting device, for detecting the first material web, a second transverse position detecting device, upstream the pressing device, for detecting the second material web and a signal processing unit, which is capable of actuating a unrolling device for unrolling the second material web so that in the device for producing a corrugated board web it is transversally displaced correspondingly.
Claims15
An assembly, comprising
- a) a first unrolling device for unrolling a first material web from at least one first material web roll,
- b) a second unrolling device for unrolling a second material web from at least one second material web roll,
- c) a device for producing a corrugated board web which is laminated on one side from the first material web and the second material web, wherein the device for producing a corrugated board web which is laminated on one side has
- i. a fluting device for fluting the first material web to form a corrugated web,
- ii. a glue application device for gluing the corrugated web,
- iii. a pressing device for pressing the glued corrugated web and the second material web against one another to form a corrugated board web which is laminated on one side, and
- iv. an exit for the corrugated board web which is laminated on one side,
- d) a first transverse position detecting device, upstream the fluting device in conveying direction of the first material web, for detecting a respective first transverse position of the first material web to produce first transverse position signals of the first material web,
- e) a second transverse position detecting device, upstream the pressing device in conveying direction of the second material web, for detecting a respective second transverse position of the second material web to produce second transverse position signals of the second material web, and
- f) a signal processing unit, which
- i. is in signalling connection with the first transverse position detecting device for receiving the first transverse position signals of the first material web,
- ii. is in signalling connection with the second transverse position detecting device for receiving the second transverse position signals of the second material web,
- iii. is in signalling connection with the second unrolling device, and
- iv. when a transverse deviation between the first material web and the second material web is established on basis of the first and second transverse position signals over a setpoint value, is capable of actuating the second unrolling device in such a way that the second material web in the device for producing a corrugated board web which is laminated on one side is displaced in its transverse direction to reduce the transverse deviation.
