Abstract:
The invention relates to a method and an apparatus for manufacturing a paperboard product, wherein the paperboard product is formed from paperboard material by means of at least one tool (13). According to the invention, the manufacture of the paperboard product (1) is controlled by determining at least one variable by means of a determining device (5) and by adjusting a selected process parameter by means of a control device (3) based on the determined variable by utilizing feedback in connection with the manufacture of the paperboard product.
Abstract:
A process for increasing the tactile properties of a base web (38) without adversely effecting the strength of the web is disclosed. In one embodiment, the process includes the steps of placing a creped base web between a first moving conveyor (60) and a second moving conveyor. The conveyors (62) are then wrapped around a shear-inducing roll (64) which creates shear forces and compressive forces that act upon the base web. The shear forces disrupt the web, increasing the softness and decreasing the stiffness of the web. The compressive forces are localized at the areas where the fabric knuckles contact the base web, imparting a unique fabric-imprinted pattern to the web with limited caliper reduction. The shear-inducing roll typically has a relatively small diameter. In some applications, more than one shear-inducing roll may be incorporated into the system.

Un procédé de transformation d'un support plan (W), dans une station de transformation (3) d'un support plan (W) comportant un groupe de découpe rotative (9) et au moins un groupe de déformation rotative (7, 8), positionné en amont du groupe de découpe rotative (9) dans le sens de déplacement (L) du support plan (W), comprend les étapes consistant à: - déterminer des paramètres de transformation du support plan (W), tels que layout de déformation et layout de découpe; - choisir un manchon (13) porteur de forme assurant la déformation, en fonction du layout de déformation; - monter le manchon (13) sur un mandrin (12) dans le groupe de déformation rotative (7, 8); - choisir les outils de découpe (91, 92), en fonction du layout de découpe; - monter les outils de découpe (91, 92) dans le groupe de découpe rotative (9); et - lancer le transformation du support plan (W).
Abstract:
Paper-based elongate structures suitable for use as lumber substitutes, articles of manufacture made thereof, kits of materials including such structures, and machines and methods for making the same. Elongate structures according to the invention include a hollow outer portion formed of corrugated fiberboard sheet material and an accordion-folded inner support formed of corrugated fiberboard sheet material. The hollow outer portion has four outer surfaces that define a rectangle when viewed in cross-section transverse to a longitudinal axis of the elongate structure. The accordion- folded inner support is enclosed within the hollow outer portion. The inner support includes a plurality of first spaced-apart peaks that contact a first inner surface of the hollow outer portion and a plurality of second spaced-apart peaks that contact an opposing second inner surface of the hollow outer portion. The accordion-folded inner support structure improves the beam strength, crush resistance and lateral strength of the elongate structure.
