APPARATUS IN WHICH A SINGLE FACE CORRUGATED WEB IS FED, WITH ITS FLUTES FACING DOWNWARDLY, THROUGH A GLUE APPLICATOR AT A COMBINING STATION AND IS WHICH PREPRINTED DISCRETE SHEETS ARE FED SERIALLY TO THE COMBINING STATION UNDERNEATH THE CORRUGATED WEB.
摘要:
A system and method for producing a board product made from paper products that have embossed medium that features an improved structural profile. The improved structural profile may include a triangular flute pattern wherein each flute may exhibit a first linear leg support and a second linear leg support that each support a center apex structure. The apex may have a substantially flat portion that is configured to engage a facing. As such, the board product may further include one or more facings that are adhesively coupled to the embossed medium. Further, the apex of each “triangle” may also have a groove or channel for receiving an adhesive in a continuous and uniform manner.

A process and an apparatus for producing faced or laminated sheets, wherein a carrier web is provided and covering sheets are adhesively attached to the carrier web and the carrier web is then divided into individual faced sections. The carrier web is provided with spaced apart, transversely extending lines of perforations. The carrier web is an endless sheet of corrugated paper and adhesive is applied to the crested side of the corrugated paper. The covering sheets are mounted on the carrier web such that when the carrier web is torn along a line of perforations, at least one of the leading and trailing edges of the respective covering sheet for the torn off section of the carrier web projects beyond the adjacent line of perforations at the end of the torn off section of the carrier web. The covering sheets are either individual sheets or a continuous web which itself is provided with lines of perforations extending transversely across the covering sheet web. Devices feed the carrier web and the covering sheets or covering sheet webs and the devices are so synchronized that the above described projection of the leading or trailing edge of a covering sheet results when a section of faced sheet is torn off. A perforating device may be provided for perforating the carrier web prior to the application of adhesive thereto. An adhesive applying roller applies adhesive to the carrier web immediately before it is faced and after it is perforated. A separating device pulls the sections of faced sheet away from the facing device and this tears each section of faced sheet away from the remainder of the web of faced sheets.

Accurate and consistent application of a label or the like to a sheet of cardboard or the like in fixed relation to a reference point on the cardboard is effected by an apparatus comprising a sheet material feeding means, a label feeding means, a label transport means synchronized with each of said sheet and label feeding means, a referencing means on said transport means in fixed relation to said label being carried thereby to cut and index said sheet material and thereby provide a uniform reference for application of said label and for further processing of said labeled sheet material. The label may be glued and as the glued label is brought into contact with the cardboard the cutting tool is operated to simultaneously notch the cardboard and/or the paper in the vicinity of the cardboard edge so that the composite cardboard-labeled sheet will be in exact relation to the print regardless of any irregularities which the edge of the cardboard might possess.

The plant includes a single facer for the production of a corrugated board. Video cameras detect any gluing defects or other defects of the corrugated cardboard. An image processing unit and a central control unit provide information about the detected defects and can act on one or more operating parameters of the plant.
