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.

An optical fiber ribbon manufacturing device includes: fiber-supplying units that respectively supply optical fibers; a printing device that prints a mark on each of the optical fibers; and a ribbon-forming device that manufactures an optical fiber ribbon by connecting the optical fibers on each of which the mark has been printed. The printing device includes: a supplying roller that supplies an ink; and a printing roller that includes a printing pattern on a surface thereof and that prints the mark on each of the optical fibers that are lined up in a width direction of the optical fibers by causing the ink supplied from the supplying roller to adhere to the printing pattern and transferring the ink onto the optical fibers. Projections and depressions are disposed on a surface of the supplying roller. The surface of the supplying roller opposes the printing pattern of the printing roller.

In a digital inking system having an anilox member that carries a patterned metered layer of ink to a digital imaging member, and a doctor blade that removes excess ink from the surface of the anilox member resulting in the patterned metered layer, an overfill form roller in rolling contact with the anilox member adds an overcoat layer of ink on the patterned metered layer for transfer of both layers of ink to the digital imaging member. The overcoat layer of ink uniformly covers all regions of the anilox member and the mattered metered layer of ink, including lands of the anilox cell walls to make the combined layers of ink pattern-free.

An inking system for use in transferring ink to a flexographic printing plate in a flexographic printing system includes an anilox member having an ink transfer zone located between first and second recessed bearing contact zones. A radius of the recessed bearing contact zones is less than a radius of the ink transfer zone by at least 0.100 inches. An ink tray includes a floor and first and second end walls. Bearings are mounted outside of the end walls which engage with the first and second bearing contact zones, respectively, thereby positioning the ink tray assembly in a specified position relative to the anilox member. Upper edges of the end walls extend into the recessed bearing contact zones.

A method is provided for printing on hollow bodies in which the hollow bodies are printed on in a decorator having a rotating segment wheel. Printing ink provided by multiple different plate cylinders and inking units are each collected on printing blankets arranged one after another on the circumference of the segment wheel. The plate cylinders and inking units involved in the printing are arranged and set in such a way that, when printing on the hollow body, an iris print is, or at least can be implemented.
