A forming device for gathering the width of a traveling web is disclosed. The forming device includes opposing arrays of flute-forming bars that can be interlaced to define therebetween a longitudinal flute-forming labyrinth effective to reduce the width of a web traveling therethrough by a preselected take-up ratio. The flute-forming bars are curved beginning at an entry end of the forming device such that they converge in a lateral direction as they proceed in the machine direction. In this manner, individual elements of the web traveling between the respective arrays in the machine direction follow contour lines along the curved bars or between adjacent ones of the curved bars so that no such element crosses any flute-forming bar in the cross-machine direction as the web travels and is fluted. A corrugating die for introducing a near-net shape to the intermediate-fluted web is also disclosed, as are a corrugating line incorporating these operations and methods for its operation.

A cutting and/or creasing rule is produced on a 3D printing machine which may be mounted on a board for use is a die for cutting and/or creasing a sheet of paperboard or other material into a blank for a carton. With the advent of additive manufacturing, i.e. 3D printing, it is now possible to eliminate traditional slotted die boards with generally rectangular steel cutting and creasing rules and replace same with surface printed boards with three-dimensional creasing and cutting rules.

The invention relates to an assembly for producing an endless corrugated cardboard web laminated on at least one side, the assembly comprising a first corrugating roller and a second corrugating roller for producing a corrugated web provided with a corrugation as well as a glue application assembly. The glue application assembly comprises a glue container for receiving glue, a glue application roller for applying the glue disposed in the glue container to tips of the corrugation of the corrugated web, and at least one glue wave inhibiting assembly arranged in the glue container for inhibiting the formation of glue waves of the glue disposed in the glue container. The assembly for producing an endless corrugated cardboard web laminated on at least one side further has a pressure assembly for pressing a cover layer against the tips, provided with glue, of the corrugated web.

An apparatus is provided for producing longitudinally corrugated product. The apparatus includes a guide roll for guiding a web of medium material, wherein at least a portion of the guide roll is adapted to be arranged at an angle relative to another portion of the guide roll. The apparatus further includes a plurality of flute forming bars oriented generally along a longitudinal axis of the web to define a first corrugating labyrinth effective to longitudinally corrugate the web to an intermediate geometry. The apparatus further includes a pair of corrugating rollers that cooperate to define, at a nip therebetween, a second corrugating labyrinth effective to longitudinally corrugate the web to a substantially final geometry. The apparatus further includes a web travel pathway for the web that follows a path around a portion of the guide roll, through the first corrugating labyrinth, and through the second corrugating labyrinth.
