Abstract

A method of continuous manufacture of a composite hollow board material comprising a first surface and a second surface, and between the first and second surfaces a plurality of distance members is disclosed. The method comprises providing material for the first surface from a first reel via a first guide roller towards an output lane; providing material for the second surface from a second reel via a second guide roller towards the output lane; and providing material for the distance members from a third reel towards the output lane such that the distance members comprises strips arranged, at any cross section perpendicular to the first and second surfaces and the direction of the output lane, perpendicular to the first and second surfaces and continuous along the output lane. The providing of material for the distance members comprises guiding at least some of the strips in a meandering pattern, and applying an adhesive to contact the strips on opposite edges thereof such that adhesion to the material of the first and second surfaces is enabled. The first and second guide rollers press the material of the first and second surfaces to the opposite edges of the strips, respectively, such that the material of the first and second surfaces are adhered to the strips. A machine for continuous manufacture of the composite hollow board material, and a computer program for controlling a machine for continuous manufacture of the composite hollow board material are also disclosed.
