Abstract

Abstract A method of forming a tape reel hub is disclosed consisting of heating a billet of aluminum, extruding the billet through an extrusion die having portions for forming a longitudinally extending tubular shaped object with metal saving cavities therein, severing the extruded tubular object to define a tape reel hub having a desired width, finishing the tape engaging face of the tape reel hub, and then the anodizing of the tape hub.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 83 words
A method of forming a tape reel hub comprising the steps of: a. heating a billet of metal to a temperature below the melting temperature of said metal; b. extruding said billet through an extrusion die constructed for forming a longitudinally extEnding tubular shaped object having a longitudinal axis; c. severing said extruded tube perpendicularly to said longitudinal axis to define tape hubs having desired widths; and d. machining an outside surface of said tape hub to form a smooth tape engaging face.
Claim 2
Independent Claim 83 words
A method of forming a tape reel hub comprising the steps of: a. heating a billet of metal to a temperature below the melting temperature of said metal; b. extruding said billet through an extrusion die constructed for forming a longitudinally extEnding tubular shaped object having a longitudinal axis; c. severing said extruded tube perpendicularly to said longitudinal axis to define tape hubs having desired widths; and d. machining an outside surface of said tape hub to form a smooth tape engaging face.
Claim 3
Dependent Claim 32 words
The method of forming a tape reel hub of claim 1 wherein said die contains portions for forming longitudinally extending cavities within said extruded tube parallel with respect to said tube axis.
Claim 4
Dependent Claim 23 words
The method of forming a tape reel hub of claim 2 further including the step of anodizing the hub after said machining step.
Claim 5
Dependent Claim 26 words
The method of forming a tape reel hub of claim 3 wherein said billet of material extruded into a tape reel hub consists of 6063T6 aluminum.
Claim 6
Dependent Claim 26 words
The method of forming a tape reel hub of claim 3 wherein said billet of material extruded into a tape reel hub consists of 6061T6 aluminum.
Claim 7
Dependent Claim 30 words
The method of forming a tape reel hub of claim 4 further including the step of dying said tape reel hub after said anodizing step to provide a jet-black finish.
Claim 8
Dependent Claim 30 words
The method of forming a tape reel hub of claim 5 further including the step of dying said tape reel hub after said anodizing step to provide a jet-black finish.
Claim 9
Dependent Claim 122 words
