Abstract: The invention concerns a sheet like composite material which consists of a uniformly corrugated web and at least one flat web connected to it by welding, soldering or gluing wherein at least one of the webs is made of metal, and a method and apparatus for continuous manufacture of said composite material.

Abstract: An apparatus for manufacturing corrugated paper material, which corrugated paper material includes a plurality of corrugated paper strips and planar intermediate inner and outer layers glued together as a unit. One of the corrugated paper strips from a production line is permitted to travel through an adhesive applicating station while the next following corrugated paper strip is moved to bypass the adhesive applicating station and placed on top of the corrugated paper strip which went through the adhesive applicating station and had an adhesive applied thereto. Thereafter, the two superposed corrugated paper strips move through a compression station to effect a tight engagement between the two strips. Thereafter, other processing steps can be performed to the united strips to enhance further handling thereof.
