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.

The invention describes a device and method for making corrugated products. The device can be used with any substrate and includes, at least, first and second drive rollers for driving a middle substrate and a single wall corrugated product. In other embodiments the invention includes upper drive rollers, lower drive rollers and middle drive rollers for driving an upper substrate, a lower substrate and a middle substrate. The middle substrate is driven between the upper and lower substrates at a higher velocity to form flutes that are anchored between the upper an lower substrates thereby forming a corrugated product. The invention also provides for customized corrugated products having multiple fluted substrates in various desirable arrangements. Examples of such products include mattress, partition panels, other furniture and construction products.

The invention relates to a method and an apparatus for the production of a corrugated cardboard product. The apparatus comprises a first single facer and a second single facer which are provided in each case with a press-down belt and with a first and a second grooving roller respectively. The first and the second grooving roller are designed for embossing a wave profile onto a first and a second paper web respectively. The press-down belts, together with the respective grooving rollers, for connecting the first and the second paper webs in each case to a non-corrugated web for the production of a first and a second single-flute corrugated cardboard web respectively. The first single facer is equipped with a first oblique guide roller, the axis of rotation of which is inclined at a vertical inclination angle between side margins of the first paper web.

The present invention makes it possible to easily adjust position so that the glue applicator roll and the corrugating roll of a single facer become parallel. In the glue application device of a single facer provided with a pair of corrugating rolls and a glue applicator roll for transferring and supplying glue to the peak-shaped ridge tops of a corrugating medium that is wound on the downstream-side corrugating roll and conveyed, the glue applicator roll position adjustment device according to the present invention is equipped with: support sections for supporting respective ends of the glue applicator roll; and parallel adjustment mechanisms, which are provided on both support sections and are for adjusting the position of the glue applicator roll to be parallel to the downstream-side corrugating roll by moving each end of the glue applicator roll and bringing both ends into contact with the downstream-side corrugating roll.

The invention relates to an apparatus for producing corrugated cardboard products. Said apparatus comprises a first one-sided machine and a second one-sided machine which are configured in each case for producing a single flute corrugated cardboard web. Furthermore, the apparatus has a combining means which is configured for connecting the single flute corrugated cardboard webs. Here, the combining means is provided with a convergence region which is configured for mutual adaptation of the single flute corrugated cardboard webs. Furthermore, the invention relates to a method for producing corrugated cardboard products, in which method a first single flute corrugated cardboard web is connected to a second single flute corrugated cardboard web. During connection, a first single flute corrugated cardboard web and a second single flute corrugated cardboard web run through a convergence region.

Corrugating rollers include an outer surface, a first flute on the outer surface, the first flute having a first height, and a second flute on the outer surface, the second flute having a second height that is different than the first height.

A unified corrugator and die-cutting system is disclosed. The system comprises: (a) a corrugator configured to produce an elongated and multi-layer moving strip of corrugated board; (b) and a die-cutting machine configured to receive said strip of corrugated cardboard and repeatedly cut it to a plurality of shaped boards.
