Regulation of the web edges
With the tension shafts with axial adjustment possibility developed by us, web edge corrections of +/- 15 mm can be realized without any problems, larger values on request.
At standstill and in set-up or inching mode, the knurled handle on the front face allows the shaft body with the roller to be moved axially. The set position is secured with the narrow knurled nut. The shaft can be actuated by means of a valve, as shown in the illustration or by a rotary seal. Other shaft diameters are possible.
If the web correction is to be carried out continuously during operation, the following solution is suitable: The shaft is integrated into the machine concept by the flange bearing. During operation, a web correction of e.g. +/- 20 mm can be made by means of a coupled linear drive. Integrated in a control system, this solution can replace much more complex conventional systems.
