Corrugated flanges for spools and reels

An apparatus for receiving, storing, and dispensing a stranded material, the apparatus comprising:

• a tubular member having an axial direction and a radial direction, configured to receive a stranded material wrapped therearound;
• and
• a first flange configured tubular member and comprising
• a core portion, having an arbor aperture therein and configured to support the apparatus on an arbor through the arbor aperture, and
• an outer portion extending radially away from the core portion to an outer edge and configured to restrain the stranded material in an axial direction,
• the core portion being corrugated to comprise a plurality of wedge-shaped web portions, and
• each wedge-shaped web portion of the plurality of wedge-shaped web portions being offset axially from adjacent wedge-shaped web portions of the plurality of wedge-shaped web portions,
• wherein the first flange further comprises a base, having corrugations, and a closure, and wherein the closure is configured to stiffen the first flange by creating a closed cross-section in corrugations of the base.

An apparatus for receiving, storing, and dispensing a stranded material, the apparatus comprising:

• a tubular member having an axial direction and a radial direction, configured to receive a stranded material wrapped therearound;
• and
• a first flange configured to engage the tubular member and comprising
• a core portion, having an arbor aperture therein and configured to support the apparatus on an arbor through the arbor aperture, and
• an outer portion extending radially away from the core portion to an outer edge and configured to restrain the stranded material in an axial direction,
• the core portion being corrugated to comprise a plurality of web portions, and
• each web portion of the plurality of web portions being offset axially from adjacent web portions of the plurality of web portions,
• wherein the outer portion is ribbed and the outer portion ribs are further configured to have a plurality of corrugations alternatingly displaced in a circumferential direction along a radial path.
