Abstract
A seam is described wherein two sheets of material are bonded together to form one unified sheet. Edges of each sheet are stepped so that one side of an edge has a stepped portion and the opposite has a planar or flat surface. The planar or stepped surfaces of the two edges are joined together to form a seam in such a manner that the thickness of the seam is no greater than one and one half times the thickness of the sheet material. This is preferably used to form a longitudinal seam in a roll of sheet material.
