Abstract: A method of making a corrugated medium which permits the use of scrap from a corrugating plant. It includes the steps of forming a web of substantially non-bonded fibres, passing the web through a nip formed by a pair of heated corrugating rolls to corrugate the web and press the fibres into intimate bonding contact thereby to consolidate the web in corrugated form, thereafter applying liners in the conventional manner.

Abstract: The invention provides a new cutter anvil attached to a winding mandrel for the making of spirally wound tubes. The tubes wound on the mandrel are transferred onto the cutter anvil to be cut to size. The anvil contains apertures openings outwardly and arranged in a ring about its leading end, and air under pressure is blown through these apertures to support the tube placed on the anvil for cutting.
