A processing machine, in particular a printing machine, includes a unit having a storage container. The storage container comprises a roller and a base which delimit the storage chamber for a medium. One or more sliders are arranged along the edge of the base to form, together with the roller, an outlet gap for the medium. In the region of the one or more sliders, pneumatic means are provided to seal the supply chamber with respect to the medium. A method for operating such a processing machine is also disclosed.

The invention relates to a glue dam seal assembly for a glue application installation of a corrugated board plant. The glue dam seal assembly comprises a support installation and a first glue dam sealing element for tight disposal on a first roller. The first glue dam sealing element is pivotable in relation to the support installation. The glue dam seal assembly furthermore has a first urging installation for urging the first glue dam sealing element onto the first roller upon generating a first urging force acting on the first glue dam sealing element.
