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.
Claims10
A printing press comprising:
- a cylinder having an outer surface and a plurality of air holes for providing air to the outer
- 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;
- a sound-damping material located on a section of the outer surface;
- and
- an axially-removable printing sleeve for fitting over the first end, the sleeve having an interior, the sound-damping material permitting the air from the plurality of air holes to pass through the sound-damping material into the interior of the sleeve.
A printing press comprising:
- a cylinder having an outer surface and a plurality of air holes for providing air to the outer surface;
- a sound-damping material located on a section of the outer surface;
- and
- an axially-removable printing sleeve for fitting over the outer surface;
- wherein the sound-damping material is made of FLOCKBAND.
A printing press comprising:
- a cylinder having an outer surface and a plurality of air holes for providing air to the outer surface;
- a sound-damping material located on a section of the outer surface;
- and
- an axially-removable printing sleeve for fitting over the outer surface;
- wherein the sound-damping material is VELCRO hook material.
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;
- providing a sound-damping surface to an outer surface of the cylinder at the free end;
- and
- passing air through or over the sound damping surface to an interior of the printing sleeve.
A printing press comprising:
- a cylinder having an outer surface and a plurality of air holes for providing air to the outer surface;
- a sound-damping material located on a section of the outer surface;
- and
- an axially-removable printing sleeve for fitting over the outer surface;
- wherein the sound-damping material is a fleece material.
A printing press with reduced noise during a sleeve-fitting operation 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;
- an axially-removable printing sleeve for fitting over the first end, the sleeve having an interior;
- sound-damping means for reducing noise caused by the air from the plurality of air holes during a sleeve-fitting operation, the sound-damping means including a sound-damping material located between the outer surface of the cylinder and the interior of the sleeve in a non-sealing manner.
