System and method for producing an articulating board product having a facing with score lines in register to fluting
11027513 · 2021-06-08 · ·

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.

System and device for evaluating operation result of corrugated paperboard box making machine

The operation result evaluation system comprises: an operation result information generation part to generate operation result information including a production count and an achieved operating time period; and an operation result evaluation device for, after completion of production of corrugated paperboard boxes for a given order, evaluating an operation result of the box making machine. The operation result evaluation device is operable to: with respect to each order, calculate an additional operating time period which is a difference between a target operating time period and the achieved operating time period; generate analytical information regarding an operating time period (FIG. 8) in each order; with respect to each of the entirety or part of a given number of orders, generate comparative information (FIG. 9); and cause the generated comparative information to be transmitted to a user terminal.
