Abstract: An apparatus for coating a strip of liquid material such as a polymer adhesive onto the surface of a traveling web at adjustable cross-directional locations which includes a transfer roll secured to a drive shaft coupled hub by an asymmetric rim plate. A carrier sleeve is secured to the hub by anti-friction bearings for independent rotation about the axis of the drive shaft. A fountain housing is secured to the carrier sleeve. The fountain housing supports a fountain nozzle for pressurized discharge of a fluid onto the perimeter surface of the transfer roll within an evacuated cavity. The cavity perimeter around the fountain nozzle has a close, sealing proximity with the transfer roll surface. An adjustable doctor blade screeds excess liquid on the transfer roll surface into the evacuated cavity for removal by a vacuum system. The apparatus significantly reduces the emissions of volatile fluids to the atmosphere during the coating process.

Abstract: Removable print roll sleeves are changed on a printing press without removal of a respective print roll from the press frame by securing the position of the print roll on the drive side axle bearing while the outboard axle bearing for the roll is removed. A bracket on a support tree has a motorized strut which bears upon an extension of the print roll axle shaft from the drive side axle bearing. This support tree may be rotated 90.degree. about a vertical axis when not in use for minimum interruption and storage. On the outboard side of the print cylinder, the axle shaft bearing is mounted on a bearing carriage for disengagement from the axle shaft journal and withdrawn by a lead screw at a 45.degree. angle along a slide plate.

Abstract: The specification describes an apparatus for providing a fluid under pressure to an exterior surface of an elongate cylinder. The apparatus is comprised of an elongate housing having a fluid collection chamber havingan opening positionable adjacent the exterior surface of the cylinder and an elongate nozzle in the housing which is projected through the opening in close proximity to the exterior surface of the cylinder. The nozzle has a length which is about equal to the length of the cylinder and a width which is less than the diameter of the cylinder. Conduits are connected in fluid flow communication with the nozzle and chamber in order to provide a flow of ink or cleaning fluid to the nozzle for inking or cleaning the cylinder under pressure and to maintain a reduced pressure in the chamber relative to the pressure of fluid exiting the nozzle.
