Method of manufacturing fibrous cores

A method for manufacturing a fibrous core, the method comprising:

• providing a strip comprising at least one liner, and at least one fluted layer, wherein the strip has a leading edge, a trailing edge opposite the leading edge, a first strip face, a second strip face opposite the first strip face, and a strip axis substantially parallel to at least one of the leading edge and the trailing edge;
• feeding the strip to a mandrel having a central longitudinal axis extending in a longitudinal direction, wherein the strip axis forms a wind angle with the central longitudinal axis;
• winding the strip onto the mandrel such that the leading edge of the strip overlaps the trailing edge of the strip to form a fibrous core comprising an inner surface, an outer surface, and a longitudinal core axis;
• and
• adhering the leading edge to the trailing edge of the strip to from an overlap portion having an overlap width.
