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.

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 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 &ldquo;false&rdquo; score lines or rolling scores.

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 fluid delivery apparatus for applying a fluid composition uniformly to the circumferential surface of a rotating transfer roll comprises a fountain having a chamber. A drain is located in a lower portion of the chamber near one end. Doctor blades meter the surface of the anilox roll. A plurality of inlet ports introduce fluid into the chamber. Each inlet port is downwardly angled toward the drain such that fluid flowing through the inlet port displaces fluid in the lower portion of chamber toward the drain end of the chamber.

A method of and apparatus for cleaning and maintaining measuring devices, in particular viscosity and pH devices, for water based Flexo inks wherein the device for measuring a parameter of the inks are mounted to a platform such as a lid adapted to cover either a cleaning container or an ink container. A cylinder raises and lowers the lid and the device for measuring a parameter of the inks in and out of the cleaning container or the ink container. A carriage carrying the cleaning container and adapted to receive the ink container moves horizontally when the lid is raised such that either the ink container or the cleaning container underlies the lid and the measuring devices. With the lid lowered on to the cleaning container, the device for measuring a parameter of the inks are washed and rinsed in the cleaning container. The device for measuring a parameter of the inks are stored in the cleaning container until returned to the ink container for use.

A method of and apparatus for loading a wiper roll against an anilox roll, wherein the wiper roll and the anilox roll each have a longitudinal rotational axis. The wiper roll is rotated about its longitudinal rotational axis and moved in a translational direction towards the anilox roll. A controller detects rotational movement of the anilox roll and stops the translation movement of the wiper roll towards the anilox roll at a specific time after detecting the rotational movement of the anilox roll in order to properly load the wiper roll against the anilox roll.

A liquid level detecting device having an overflow reservoir, a flow restriction means and a level detecting means. The reservoir defines a cavity for collecting an electrically-conductive liquid overflowing from a container. This reservoir, which has a low level position associated therewith, includes inlet means through which the overflowing liquid enters, outlet means through which the collected liquid exits, and vent means through which built-up gases escape. Flow restriction means controls the rate at which the collected liquid exits through the reservoir's outlet means. Flow restriction means is calibrated such that the rate at which liquid exits the reservoir does not exceed the rate at which liquid overflows therein. In one embodiment, level detecting means includes a capacitive sensor switch which is fixedly secured to the reservoir to detect whether the liquid level is below the reservoir's low level position. In another embodiment, level detecting means includes a positive and a negative electrical probe attached to, and/or associated with, the reservoir. The positive and negative probes are electrically insulated from one another, in electrical communication with the reservoir's cavity, and positioned to detect whether the liquid level is below the reservoir's low liquid level position. In still another embodiment, an electrical probe is arranged to be in contact with ink overflowing from a second reservoir. This overflow condition is indicative that a normal flow of ink exists within the system.

A divider seal for a split-fountain chambered doctor blade for a printing press, comprising a seal contoured to sealingly engage a circumferential surface of a rotating cylinder, a seal retainer for retaining the seal in sealing engagement with the rotating cylinder, and pneumatic biasing structure, such as a pneumatic bladder, acting on the seal retainer for resiliently biasing the seal into sealing engagement with the rotating cylinder.

A dual pressure preload system preloads a doctor blade assembly in intimate contact with an anilox roll. The doctor blade assembly is attached to at least one end wall of an ink chamber. The ink chamber directly applies ink to the circumferential surface of the roll. A pressure chamber is attached to the ink chamber on the side opposite the roll and maintains the doctor blade assembly adjacent the roll. A differential pressure is produced by the pressure chamber providing a consistent preload force applied to the anilox roll by the doctor blade assembly. In one embodiment, a relatively compressible fluid, such as a gas, is compressed, which, in turn, acts on a relatively incompressible fluid, such as a liquid, the relative incompressible liquid supplying the pressure in the pressure chamber. In another embodiment, a clamp provides a biasing force, independent of the pressure chamber, for independently preloading the doctor blade assembly in intimate contact with the anilox roll, in the event of a failure of the pressure chamber.

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.
