Abstract
In a corrugated cardboard machine and in a method of producing a web of corrugated cardboard, an electronic control device is provided in order to avoid downtimes of the corrugated cardboard machine, said control device being designed such that at least one web length of the web of corrugated cardboard between the at least one production device and a longitudinal cutting device is detectable and an application width of the at least one production device is variable in dependence on the at least one web length. Changing the application width prevents an escape of glue from the sides so that there is no need for cleaning.
