Method of manufacturing fibrous cores

摘要

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, 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; and adhering the leading edge to the trailing edge of the strip to form the overlap portion having an overlap width.
