A device for printing board or cut sections of board comprising a number of print stations through which the board is arranged to pass successively to receive print images from one or more of the print stations and at least one print station. The print station comprising a print cylinder mounted in a laterally displaceable carriage which can be moved laterally away from the board travel line, leaving in place substantially all the remaining parts of the at least one print station, to allow changing of printing plate or plates on the print cylinder while the printing apparatus can continue to operate with one or more of the other print stations.

A method and apparatus for preparing container board having a corrugated medium and at least one liner formed thereon for folding which comprises a tool for displacing in a non-destructive manner the corrugated medium and the liner in a portion of the board to form a curved indentation therein. The device includes a separate tool for forming a line of weakness in the liner along the curved indentation portion of the board. This arrangement increases the dimensional accuracy of the container board by substantially eliminating the occurrences of âfalseâ score lines or rolling scores.

A corrugated box finishing machine has a station where dust, debris and other particles are cleaned from the corrugated boards before they are conveyed to the printing station. Electrostatic charges on the particles are neutralized by a static bar and the particles are then removed from the boards by a rotating brush. The particles are drawn into a vacuum chamber underlying the path of conveyance of the boards, and the static bar is positioned in an enclosure in proximity to the boards but isolated from the vacuum in the vacuum chamber. The enclosure has surfaces which direct the particles away from the static bar which is oriented to further minimize contact with the removed particles. The cleaning brush includes a plurality of brush sections mounted on a rotatable shaft made from carbon fiber material.

A multi-purpose layout tool has an elongated main body component and a slide block component. Each component is designed to be used separately or in combination to perform a multitude of functions. An elongated opening extends substantially the length of the main body. The opening is configured to accept a slide block guide member extending from the slide block, which is secured within the opening by a threaded knob. The slide block can be adjustably secured within the opening, at designated angles in relation to the main body. The slide block also has a number of features, including dual level members and a compass pin which is used in conjunction with the main body for circular measurement, layout, and marking.

An apparatus and system for monitoring liquid flow and detecting low flow conditions. The apparatus includes a liquid collection reservoir having a cavity, an inlet through which liquid enters the reservoir cavity, and an outlet through which the liquid drains from the cavity. A first flow restrictor upstream of the inlet is selectably openable and closeable to regulate flow of the liquid into the cavity, and a second flow restrictor downstream of the outlet is selectably openable and closeable to regulate flow of the liquid from the cavity. A controller controls the state of the flow restrictors to alternately open the first flow restrictor and simultaneously close the second flow restrictor for a first period of time to allow fluid to enter and remain in the cavity, and then close the first flow restrictor and simultaneously open the second flow restrictor for a second period of time to prevent fluid from entering the cavity and allow fluid to drain from the cavity. A sensor operatively associated with the cavity senses whether liquid in the cavity reaches a preselected level during the first period of time.

Downstream of the cleaning brush a plurality of magnets extend transversely adjacent the path of conveyance to attract and remove metallic particles from the boards as they are conveyed to the printing station.

An apparatus for evacuating ink from the inking trough of a flexographic printing machine uses an air ejector nozzle in the ink drain line to draw ink from the trough. The apparatus includes an air-operated control system in which air valves control an air-bladder pinch valve in the ink drain line and an oil-bladder pinch valve in the air ejector line. An air pressure regulator maintains a pressure charge on an accumulator associated with the oil-bladder pinch valve, in order to provide a gradual increase of air flow to the ejector nozzle to prevent sudden vacuum surge that might over-flex the doctor blades.
