Abstract: An improved system for fabricating convolutely wound tubes includes a supply roll support for supporting a large supply of paperboard, an adhesive applicator for receiving paperboard from the supply roll and applying a coating of adhesive to one side thereof, a cutting station for cutting the paperboard across its length to form sheets of paperboard, and a winding station including a mandrel about which cut sheets of adhesive bearing paperboard are wound into a tubular configuration. As the paperboard is drawn from the supply roll, one of its edges passes sequentially through three corrugating nip rolls, which alternately deform the material of the edge to render it more pliable and flexible. This flexible edge, then, becomes the trailing edge of paperboard sheets that are wound into tubes such that the edge can be easily conformed to the contour of and adhered to the outer surface of the finished tube.
