Abstract
A printing press comprises a cylinder having an outer surface and a plurality of air holes for providing air to the outer surface. A sound-damping material is located on a section of the outer surface and an axially-removable printing sleeve fits over the outer surface. Also disclosed is a method for reducing noise from a printing press comprising the steps of providing air through air holes in a cylinder having a free end to aid in placement or removal of an axially-removable printing sleeve, and providing a sound-damping surface to an outer surface of the cylinder at the free end.
Claims8
A printing press comprising:
- a cylinder having an outer surface and a plurality of air holes for providing air to the outer surface, the cylinder having a first end and a second end, the first end capable of being free, the outer surface having a sound-damping roughened section including threading, the roughened section being provided between the plurality of air holes and the first end;
- and
- an axially-removable printing sleeve for fitting over the first end, the sleeve having an interior, the sound-damping roughened section permitting the air from the plurality of air holes to pass over the sound-damping roughened section into the interior of the sleeve.
