A system and method for producing a board product made from paper products that have a pre-scored facing in addition to a medium (sometimes called fluting). Conventional corrugated board may feature a cross-corrugated medium and one or more facing that have no score lines that are imprinted (at least prior to assembly with the corrugated medium). Such a conventional board product may be inferior because any score lines that are imprinted will damage the underlying corrugated medium in some manner. A breakdown in the strength of the underlying medium leads to poor precision when the eventual board product is scored, cut, and bent. A lack of precision in folding a board product is known as fishtailing as any articulated portion of the board product may not maintain a precise plane of articulation when bent. Hence, the articulated portion “fishtails” out of alignment. Having precisely located impression lines in register to underlying flutes of a medium ensures correct and precise articulation.

A bearing for holding a rotary conversion tool (10, 11) that includes two end rolling bearing devices (26, 28), at least one intermediate rolling bearing device (27) interposed between the end rolling bearing devices (26, 28), the end and intermediate rolling bearing devices (26, 27, 28) being intended to engage with an end (10a, 10b, 11a, 11b) of the rotary tool (10, 11), and at least one mechanical actuator (32, 33) configured to exert a radial preload force (Fo, Fo′) at the intermediate rolling bearing device (27).

The invention relates to a method of creasing sheets (12) by using a creasing tool (14, 20, 21) cooperating with a counter element (22, 23), comprising the following steps: a creasing plate blank (24′) is provided with at least one creasing projection (26) by plastically deforming the material of the blank (24′) so as to form a creasing plate (24), the creasing plate (24) is mounted to a creasing tool (14, 20, 21), sheets (12) to be provided with at least one crease are advanced through a gap between the creasing tool (14, 20, 21) and the counter element (22, 23).

A carton sizing system (1) that has a frame (2), a controller (4), one or more cutters (51) movably mounted to the frame (2) and operatively connected to the controller (4), one or more markers (61) movably mounted to the frame (2) and operatively connected to the controller (4). The carton sizing system (1) also has a measuring system (7) that is operatively connected to the controller (4) and configured to determine, in use, the footprint of an open top carton and to determine the height of one or more objects contained within the carton. The controller (4) is configured to position the one or more cutters (51) based on the determined footprint and to cut vertical edges of the carton based on the determined height and also to position the one or more markers (61) based on the determined footprint and eight and to score or crease vertical walls of the carton between the vertical edges to at least partially define foldable panels.

A creasing device includes a frame with a substantially horizontal support surface for supporting an article to be creased; a movable tool; and a stationary tool, the latter comprising a stationary member and at least one displaceable member whose height relative to the stationary member can be adjusted. A first actuator moves the movable tool toward the stationary tool and interacts with opposite faces of the article, and a second actuator translates the displaceable member between a first end position in which interacts with the movable tool and a second end position in which it cannot interact with the movable tool. Guide means associated with the stationary tool guides the displaceable member between the first end position and the second end position. The guide means are have a curvilinear path contained in a plane substantially perpendicular to the support surface.

A box formed from a plastic corrugated material with soft score lines is provided. The soft score lines are formed to enable the top flaps of the box to lay substantially flat against the outer surface of the box when folded to an open position.
