  • Drilled unported vacuum drum with a porous sleeve
    Patent number: 4998658
    Abstract: An unported vacuum drum has a system of closely spaced small grooves in the outer surface thereof and holes drilled in the drum provide communication between the grooves on the outer surface and a space on the interior of the drum. The interior drum can be connected to a source of vacuum for applying the vacuum through the holes to the grooves. In order to avoid defects that may occur in a web brought into contact with a drum, the outer surface of the drum is covered with a porous sleeve. The pores in the sleeve enable the vacuum to be applied from the grooves to the outer surface of the sleeve for holding the web onto the sleeve.
