Abstract

Methods and machine for manufacturing vertically oriented core of multiwalls and multiwalls comprising such core. Multiwalls or cores of multiwalls with transversely oriented flutes in their core are sliced perpendicularly relative to the axis of rotation of the flutes The slices are bent 900 relative to the origin multiwall or core, packed together, welded or fused and their top and bottom surface leveled to provide a vertically oriented shortened flutes that form the core. The top and bottom surfaces of the core are then laminated, Machine configurations are also provided for continuous manufacturing of vertically oriented cores of multiwalls.
