The present disclosure is directed to a method for manufacturing a fibrous core comprises: providing a strip comprising at least one liner, and at least one fluted layer, wherein the strip has a leading edge, a trailing edge, a first strip face, a second 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; 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.

1. 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,

1. 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, a thickness, and a strip axis substantially parallel to at least one of the leading edge and the trailing edge;compressing one or both of the leading edge or the trailing edge located in an overlap portion of the strip to about one-half the thickness;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; andadhering the leading edge to the trailing edge of the strip to form the overlap portion having an overlap width. 2. The method of claim 1, wherein the outer surface comprises a fluted layer and wherein the inner surface comprises a liner. 3. The method of claim 1, wherein at least one of the first strip face and the second strip face comprise indicia positioned at an angle to the strip axis. 4. The method of claim 3, wherein the indicia is positioned at an angle of about 45 degrees from the strip axis, and wherein the wind angle is about 45 degrees. 5. The method of claim 3, wherein the indicia disposed on the outer surface is oriented substantially perpendicular to the longitudinal core axis. 6. The method of claim 3, wherein the indicia on the inner surface is oriented substantially parallel to the longitudinal core axis. 7. The method of claim 3, wherein the indicia is positioned at an angle from about 0 degrees to about 90 degrees from the strip axis. 8. The method of claim 3, wherein the angle of indicia on the strip axis and the wind angle form the fibrous core comprising indicia, wherein the indicia disposed on the outer surface of the fibrous core is positioned at a reading orientation when the fibrous core is in a dispensing position, and wherein the indicia disposed on the inner surface of the fibrous core is positioned at a reading orientation when the fibrous core is in a shipping position. 9. The method of claim 3, wherein the indicia comprises at least one of a letter, a word, and a symbol. 10. The method of claim 1, wherein the strip comprises a single face corrugate material. 11. The method of claim 1, further comprising applying adhesive to at least one of the first strip face and the second strip face. 12. The method of claim 1, wherein the overlap portion has a height less than two times the thickness of the strip. 13. The method of claim 1, further comprising applying adhesive to at least a portion of the outer surface of the fibrous core. 14. The method of claim 1, further comprising cutting the fibrous core to a length of between about 2.5 inches and about 14 inches. 15. The method of claim 1, further comprising embossing the strip to form indicia on at least one of the first strip face and the second strip face. 16. The method of claim 1, further comprising printing the strip to form indicia on at least one of the first strip face and the second strip face. 17. The method of claim 1, further comprising printing and embossing the strip to form indicia on at least one of the first strip face and the second strip face. 18. The method of claim 1, wherein an adhesive is present on about 20% to about 100% of the overlap width.
