TM: Grooving Surface...

New service offering by JAEGER GmbH:
grooves in the surface of a support roll

An additional service has been added to the range of services, the JAEGER GmbH is able to provide to it´s customers: the application of grooves into cylinder surfaces. Of course  perfectly executed and with a clean deburring of the edges ... 

In order to prevent the lifting of paper web from the cylinder surface at faster machine speeds,  longitudinal grooves are milled into the surface of the support rolls. That should prevent the formation of air pockets getting between material and roll, which would break the contact necessary for a good traction.

Besides the classic grooving in machine direction of approximately 10% of the surface, there is another option for additional grooves with radius that are more flat and at the same time wider and in diagonal direction. This further improves the removal of air pockets between material and roller.

Of course, the grooves should not leave any marks on the paper web. The better the grooving is done, the easier the cleaning of the pollutions apearing during operation will be. To carry out this work, we developed a machine, that is able to do the grooving in situ (just like our grinders).   ►►

Restorage of existing grooves...

In addition to the service of applying  a new grooving the restoring of  already existing grooves  could be a necessary step. This is especially true when the roll shape previously had to be  optimized with a contour grind. Some of the existing grooves might have been reduced to a depth lower than required by wear and tear during machine operation, and of course some of them will be reduced or even deleted with any necessary grinding.

Also in these cases our mobile grooving machine will be used, to restore a constant and optimal depth of the grooves and by this ensures the future optimal operation of the cylinder.
