A powder sprayer unit which provides improved spraying of powder onto printed sheets of material produced in printing presses. The powder sprayer includes a source of pressurized fluid, a source of powder, a mixer and a distributor. The mixer includes at least one fluid inlet positioned to receive fluid from the fluid source, and at least one powder inlet positioned to receive powder from the source of powder to mix the fluid and the powder forming a fluid/powder mixture. The distributor-includes a disperser positioned to disperse the mixture as it flows to a plurality of nozzles. The nozzles are positioned to spray the dispersed mixture onto specified areas of printed sheets of material having passed through the printing press.

Powder sprayer

A vertically oriented feeder for a packaging manufacturing system is provided. The feeder supports a stack of blanks in an upright position and in a confronting relationship with a vertical vacuum belt. The vacuum belt draws a front blank off of the stack and pulls it upward past a gate and between the vacuum belt and a friction belt. After the blank is pulled upward past the gate, a lifting device is activated to push the stack away from the vacuum belt and prevent additional blanks from being drawn upward by the vacuum belt until the lifting device is retracted or de-energized. The lifting device ensures that adequate spacing is provided between adjacent blanks and that the timing of the placement of the blanks on the succeeding flighted belt is sufficiently accurate so that downstream operations may be carried out by automated equipment.

Upright feeder for packaging manufacturing systems

A stand alone printing system (10) for coating a first face of sheets on which printing may be printed previously by a printer not associated with the system includes a feeding mechanism (14), a driven application roller (76) for transferring coating material disposed on the peripheral surface (77) to the first face; a metering device (78) for transferring a uniform thickness of coating material to the peripheral surface of the application roller; a driven impression roller (85) which contacts a second face of the sheets and which contacts the peripheral surface of the application roller at least at gaps disposed between the sheets during feeding of the sheets along the coating zone which transfers the coating material to the peripheral surface (86) of the impression roller; and a coating material removing mechanism (116) for removing coating material from the peripheral surface of the impression roller prior to rotation of the peripheral surface of the impression roller to a point of contact with the second face of the sheets to prevent the transfer of the coating material to the second face of the sheets.

Stand alone coating apparatus for printed material and method of

An addition to a multi-color lithographic offset printing press comprising a self-contained coating unit moveable into and out of operative relationship with an impression cylinder on the press unit (e.g. the impression cylinder of the last press unit) without interrupting or disrupting printing taking place in this last stage. The coating unit includes a special blanket cylinder, a transfer cylinder and doctor or metering means to control the amount of coating material on the transfer cylinder. Inclined tracks are provided to guide the coating unit into and out of operative relationship with the impression cylinder of the last printing stage.

Retractable coater assembly including a coating blanket cylinder

A retractable coater is used on-line with the last unit of a standard offset lithographic printing press. The coater includes a coating assembly mounted on a platform and a retraction guide assembly, the latter comprising:

Vertically retracting coater

Apparatus for applying a liquid coating to the surface of a sheet workpiece and adapted for operation on-line with the last unit of a lithographic sheet printing press. The apparatus comprises: (1) a textured metering roller in a mount which is linearly movably attached to a support platform fixed adjacent the press unit, and extending between the last press unit and a remote point. The support platform allows movement of the metering roller and the mount between a first position in which the mount is continuously adjustably biased against the last press unit, and a second position, away from the last press unit to allow use of the last press unit as a lithographic press. The platform comprising longitudinal supports arranged generally perpendicular to a vertical plane through the axis of said metering roller, and the metering roller mount is movably supported and guided along the supports. In the first position, the metering roller continuously delivers a smooth, uniform, metered amount of liquid material to the blanket roller of the printing press. The apparatus also includes a latch that allows the mount, with its attached metering roller, liquid coating supply, and metering roller rotation device, to be readily detached from and moved out of the way of the press unit, so that the press unit can be used as a lithographic press unit. A biasing latch and an adjustable stop allow the metering roller and mount to be readily and reliably returned, locked and biased in the first position.

Coating printed sheets

A shipping carton erecting and holding device comprising: a support structure for supporting a carton in an upright position during loading; and a discharge means for discharging a filled carton from the device which includes a U-shaped engaging member to engage one end of, and to extend at least partially around the sides of, a carton, and a pair of horizontal spaced-apart rails, positioned entirely between the side walls of the device and entirely forward of the rear wall; a drive means communicating with the U-shaped member to move it between a first position on the rails in which the member is positioned to engage one end of a said carton supported on said support structure, and a second position spaced generally horizontally from said first position whereby movement of said member from said first position to said second position will move a said carton off of said support structure and discharge it, the drive means being mounted along one side wall, entirely forward of the rear wall of the device. A method of using a shipping carton and holding device with automatic sequencing features is also disclosed.
