Embossment Protective Feature for Core Tubes

A tube for winding a web of fabric or other material thereon, comprising:

• an inner tube comprising a plurality of inner layers that are wound one upon another about a longitudinal axis of the inner tube and adhered together, the inner tube having a cylindrical inner tube outer surface;
• an outermost layer formed by a strip of material that is helically wound around the inner tube outer surface, wherein the outermost layer has a tube outer surface and a plurality of raised gripping portions extending radially outward from the tube outer surface by a raised gripping portion distance, wherein an overlap seam is formed by one of the plurality of inner layers or the outermost layer with a first edge of the one of the plurality of inner layers or the outermost layer being applied to an underlying layer and a second edge of the one of the plurality of inner layers or the outermost layer being applied to the one of the plurality of inner layers or the outermost layer over the first edge and overlapping the first edge;
• and
• a raised protective strip formed in a portion of the outermost layer that overlies the overlap seam, wherein the raised protective strip extends radially outward from the tube outer surface by a protective strip distance.

A method for forming a tube for winding a web of fabric or similar material thereon, comprising:

• forming an inner tube having a plurality of inner layers that are wound one upon another about a longitudinal axis of the inner tube and adhered together, the inner tube having a cylindrical inner tube outer surface;
• forming an outermost layer from a strip of material that is helically wound around the inner tube outer surface, wherein the outermost layer has a tube outer surface and a plurality of raised gripping portions extending radially outward from the tube outer surface by a raised gripping portion distance;
• and
• forming a raised protective strip at the outermost layer that helically wraps around the outermost layer such that at least a portion of the plurality of raised gripping portions are uncovered and exposed to an exterior of the tube, wherein the raised protective strip extends radially outward from the tube outer surface by a protective strip distance.
