The invention relates to a glue dam seal assembly for a glue application installation of a corrugated board manufacturing device. The glue dam seal assembly comprises a support installation and a first glue dam sealing element for tight disposal on a first roller, which sealing element is disposed on the support installation.

A corrugated pizza box is made using a web fed rotary die cutter with the web produced by a corrugator singlefacer that is speed synchronized with the rotary die cutter. The singlefacer produces SemiCorr Singleface Board (SSB) made possible by special corrugating rolls that allow a bottom liner to be bonded to a fluted and creased medium or liner within the singlefacer. This medium or liner has cross flute bond lines that provide in-line stiffness to the two-ply board exiting the singlefacer.

The present disclosure is directed to a shipping container with a corrugated medium that lines an interior pocket of the shipping container as well devices and components (e.g., corrugating rollers, corrugating machines, scoring rollers, and scoring machines) that are utilized to manufacture the shipping containers. The corrugated medium has flutes that cushion, support, and protect a product that is shipped within the shipping container. The corrugated medium may include a first portion with first flutes and a second portion with second flutes that are offset relative to the first flutes. The offset first flutes and second flutes results in peaks of the first flutes nesting within valleys of the second flutes, and peaks of the second flutes nesting within valleys of the first flutes.

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.

A apparatus for creating corrugated cardboard (20) in particular on the site of a system for automatically forming packaging boxes, said corrugated cardboard having at least one corrugated layer (10) between two flat layers (12, 18). The apparatus includes a joining station (16) for attaching a second flat layer (18) to a corrugated layer (10) provided on a first flat layer (12), means for supplying said corrugated layer (10) with the first flat layer (12) attached thereto to said joining station (16) and means for supplying said second flat layer (18) to said joining station, means for removing a protective layer (28) from the corrugated layer (10) and/or the second flat layer (18), said protective layer (28) protecting an adhesive substance provided on the corrugated layer (10) or the second flat layer (18).

A device includes a tank for storing a glue solution; a roll having a surface for transferring the glue solution onto an area of a corrugating medium of a single-faced corrugated fiberboard sheet in the width direction; scraping members for regulating adhesion of the glue solution outside the area on the surface of the roll; a movement mechanism for moving the scraping members in the width direction; and a control device for setting, on the basis of the cutting width dimension with which the double-faced cardboard sheet is to be cut after passing the roll, the area to be a region in which margins in the width direction have been added outside positions of the side edges of the cutting width dimension, and for controlling the movement mechanism to dispose the scraping members at positions corresponding to the positions of the side edges of the glue application region.

A device for cardboard storage and removal for a bridge in a corrugated cardboard production line includes a bridge over which a conveyor system for conveying the single-sided laminated corrugated cardboard web is arranged. The exit end of the conveyor system for conveying the single-sided laminated corrugated cardboard web is provided with a clamping and cutting unit and a movable cardboard storage carriage unit is provided under the conveyor system for conveying the single-sided laminated corrugated cardboard web, under which conveyor system a conveyor belt system is provided in the bridge, and in the bridge an opening is provided, under which a waste cardboard collecting carriage is provided. The movable cardboard storage carriage unit stores the cardboard by means of cardboard storage rolls, which retain the single-sided laminated corrugated cardboard web flat on the bridge. In the event that a splicing defect is detected, the defective piece is cut out by the clamping and cutting unit and ejected by the conveyor belt system to the waste cardboard collecting carriage through the opening. Hence, it follows that productivity is improved.

A machine for producing a corrugated-board web with at least one cover web and at least one corrugated web connected with the same by a gluing. The machine includes at least one microwave quality determining unit for determining at least one dielectric characteristic of the corrugated-board web for determining the quality of the same by microwaves.

A method for making a dual fluted corrugated board includes providing a first single face corrugated board having a liner layer and a fluted layer attached to the liner layer and providing a second single face corrugated board having a liner layer and a fluted layer attached to the liner layer. The method also includes arranging the first single face corrugated board and the second single face corrugated board such that the fluted layers thereof face one another and attaching the first single face corrugated board to the second single face corrugated board.
