A means of making a multi ply structural panel by eliminating the top liner in the corrugating process. The present invention is made possible through modification to the corrugating rolls of the singlefacer. The design modification to the rolls involves incorporation of slots that run around the circumference of one roll and mating creasing tools incorporated around the circumference of the other of the corrugated roll set. These slots and creasing tools are incorporated across the existing flutes of the corrugating rolls.

The invention relates to a glue dam seal assembly for a glue application installation of a corrugated board plant. The glue dam seal assembly comprises a support installation and a first glue dam sealing element for tight disposal on a first roller. The first glue dam sealing element is pivotable in relation to the support installation. The glue dam seal assembly furthermore has a first urging installation for urging the first glue dam sealing element onto the first roller upon generating a first urging force acting on the first glue dam sealing element.

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.
摘要:
A method of bonding a substantially planar sheet material to a corrugated sheet material using an automated process the method characterized by the steps of a) applying adhesive in discrete amounts to the contact points of the corrugated sheet material, and b) holding the sheet materials together until a bond is formed between them.

A machine for producing corrugated paper has a machine frame, a fluted roller and a glue application roller, which can be placed against the fluted roller and between the surface of which and the fluting the paper web to be provided with a corrugation and to be partially glued can be guided through. Provided between the fluted roller and the glue application roller and to the side of the fluting is at least one spacer, which maintains a safety gap with a gap width d between the surface of the glue application roller and the fluting, the gap width d being smaller than the smallest thickness of the paper web.

A device for gluing of a double facer includes a glue bath containing glue; a gluing roll immersed in and coated with the glue; a doctor roll adjusting the glue on the gluing roll to a predetermined thickness, transferred to a single faced corrugated cardboard; a swing roll disposed at an upstream portion of a transferring direction of the corrugated cardboard; and a moving device that moves the swing roll in a direction that the single faced corrugated cardboard is wrapped around the gluing roll. The swing roll is wrapped around the single faced corrugated cardboard, and the number of flute tips of the single faced corrugated cardboard that are concurrently contacting with the gluing roll and applied with the glue is adjusted by moving only the swing roll in such a direction that crosses a sheet face of the single faced corrugated cardboard passing through the nip.

A method for automatically setting the rider roll/glue applicator roll gap for the single face web on a glue machine senses a forward drag that the single face web, operating at corrugator speed, exerts on the glue applicator roll, driven at an underspeed, after bringing the flute tips of the single face web into contact with the glue applicator roll by adjusting the position of the rider roll. Changes in forward drag exerted on the glue applicator roll are monitored and related directly to glue applicator roll drive current to provide a slight compression of the single face web between the rider roll and the glue applicator roll. Preferably, the glue applicator roll uses a regenerative drive and the target drive current command in a feedback control system to cause the gap to be adjusted to achieve the desired slight compression of the web flutes and to maintain the glue applicator roll under speed.

A production equipment for corrugated paper comprises a bonding device having a base, and a guiding assembly is installed in base and a driving mechanism is installed adjacent to guiding assembly, in which space is created between driving mechanism and guiding assembly for mutually squeezing and bonding glue layers among lining paper, paper material and sandwiched core-paper to form paper board, and bonding device is configured with a heating tool. A pre-heater capable of heating sandwiched core-paper is installed on input side of base to perform pre-heating to sandwiched core-paper by means of pre-heater before heating lining paper, paper material and sandwiched core-paper in heating tool, so speed for solidifying and bonding between glue layers of paper material and sandwiched core-paper can be effectively accelerated through the temperature contained in itself thereby lessening the number of elements installed in the subsequent heating process and reducing manufacturing costs of corrugated paper.
