Abstract:
A process of manufacturing a cardboard building construction material, said cardboard building construction material comprising a plurality of glued cardboard plies, wherein the cardboard plies are rolled on a drum (122) into a roll (114) and wherein glue (134) is circumferentially applied in spaced apart strips (238) thereby defining a non-glued region between the strips, in which region a cutter (246) cuts the cardboard plies from an outer diameter toward an inner diameter of the roll (114).
