Abstract: A method of manufacturing an adhesive composition for use in the production of paperboard is provided. An amount of water contained within a source container is provided. The water is heated to a first temperature. A rheology modifier is added to the heated water to create a heated solution. A starch is added to the heated solution. The heated solution is mixed for a first period of time to create a heated mixture. Additionally, there may be more independent time segments determining an amount of time which the components of the heated solution are mixed or blended together. Additional elements of the adhesive composition are added to the heated mixture between each mixing time segment.

Abstract: A door mounting system for mounting a door includes a door mounting frame and a lifter mount. The door mounting frame is attachable to a door and is removable from that door. The lifter mount is attachable to a propulsion device such as a forklift. The lifter mount is attached to the door mounting frame so that the propulsion device provides a way to transport the door mounting frame and the door to a location where it is desired to install the door.

Abstract: A system and method for producing a more desirable sheet of cardboard is provided. The system includes a corrugating device, a pressure exerting device, and a double backing device. The double backing device includes a set of hot plates operatively connected to a temperature control system to independently control the temperature of each hot plate within the set. By varying the temperature of each plate, the system can produce a sheet of paperboard with evenly cured adhesive lines to reduce warping and reduce delamination. The method of the present invention includes the steps of feeding a sheet of paperboard over the set of hot plates to evenly cure the adhesive with varying plate temperatures.

Abstract: A liquid metering system in the manufacture of paperboard includes a moisture applicator roll. The moisture applicator roll is configured to rotate about its axis generally perpendicular to a paperboard material flow stream. As the moisture applicator roll rotates, it has a tangential velocity. The tangential velocity is a percentage of the linear velocity of the paperboard material moving down the flow stream. The moisture applicator roll contacts the material at a contact location. At the contact location, the direction of the tangential velocity of the applicator roll opposes the direction of flow of the material. The percentage of the tangential velocity of the applicator roll relative to the linear velocity of the material is generally in a range from about 2% to about 160%.

Abstract: A splicing machine having an alignment mechanism is provided for aligning an end edge of a web of paperboard in preparation for splicing two webs of paperboard. An image display device such as a mirror or display screen allow an operator to view images of the end edge of the web and the alignment position to facilitate aligning the end edge at the alignment position. The alignment position is typically marked by an alignment marker produced by light, such as a laser beam.

Abstract: A method and apparatus for verifying stack size are disclosed wherein measured length and width dimensions of a stack of paperboard sheets are compared with length and width values of a label associated with the stack. The dimensions are typically measured as the stack travels along a conveyor. A no-match indicator is produced if there is not a match between the dimensions and values, and may include an alarm or a display on a video screen. The stack may be diverted to allow application of a correct label whereby the stack will be shipped to the correct customer.

Abstract: A method and system for automatically changing the flute size in a corrugation process without stopping or slowing the overall corrugation process utilizing a first single-faced web having a first flute size and a second single-faced web having a second flute size. The first single-faced web is conveyed along a track into a double backer forming a first corrugated material. When a flute change sequence is initiated, the single-faced web is cut using a pressurized stream of water such that the single-faced web disengages with the double backer. Generally simultaneously, the second single-faced web is introduced into the double backer using an air jet, wherein a second corrugated material is formed.

Abstract: A corrugator includes a separation sensor for sensing separation of a corrugated medium and liner of a corrugated paperboard. Sensing the separation, also known as blowout or fluff out, allows the corrugator to be controlled to prevent problems which arise when corrugated paperboard having such a separation continues downstream along the corrugator. Typically, the corrugator is operated to cease downstream movement of the paperboard while a faulty segment which includes the separation is removed and the problem causing the separation is fixed, thereby providing for subsequent production of corrugated paperboard which is properly glued.

Abstract: This invention relates to a machine and system for processing strip material which typically is removed from the edges of a sheet of material during the formation process. The strip material is formed in an apparatus and expelled at a variable line speed. The line speed is measured by a sensor which provides a signal representation of the speed to a cutter assembly. The cutter assembly cuts the strip material at a cutting speed which is sequenced to the line speed such that the strip material is cut into a plurality of pieces. The pieces are generally uniform in shape and size across variations in the line speed because the cutting speed is synchronized with the line speed.

Abstract: A paperboard handling machine includes an alignment mechanism for aligning rolls of paperboard supported by the machine whereby the rolls are aligned with one another.

Abstract: This invention relates to a method for producing corrugated material and processing strip material which is removed from the edges of the corrugated material during the formation process. The strip material is cut away from the corrugated material and expelled at a variable line speed to a trim processing machine. The line speed is measured by a sensor which provides a signal representation of the speed to a cutter assembly. The cutter assembly cuts the strip material at a cutting speed which is sequenced to the line speed such that the strip material is cut into a plurality of pieces. The pieces are generally uniform in shape and size across variations in the line speed as the cutting speed is synchronized with the line speed.
