Abstract

A coil cap cover for a cylindrical coil of aluminum stock provides a round fabric portion 20 sized to fit either end of the cylindrical coil of aluminum and a substantially rectangular attached fabric skirt portion 50 which covers an adjacent portion of the cylindrical sidewall of the coil. A welded region 70 connects a perimeter edge of the round fabric portion to an upper edge of the fabric skirt portion, creating a three-dimensional coil cap. An overlap weld 80 fastens the upper edges of the ends of the skirt portion together with a segment of the perimeter of the round fabric portion. A crimp weld 90 fastens a lower corner of each end of the skirt portion together.

Claims

1. A coil cap, adapted to cover an end surface and an adjacent portion of a sidewall of a cylindrical body, comprising:

(A) a round fabric portion made of woven coated polyethylene;

(B) a fabric skirt portion, made of woven coated polyethylene, wherein the thickness of the fabric skirt portion is approximately one-half the thickness of the round fabric portion;

(C) a welded region joining an upper edge of the fabric skirt portion to a perimeter edge of the round fabric portion, thereby forming a three-dimensional coil cap; and

(D) an overlap weld joining the upper edge of the fabric skirt adjacent to a first end of the fabric skirt to the upper edge of the fabric skirt adjacent to a second end of the fabric skirt to a segment of the perimeter edge of the round fabric portion.

2. A coil cap, adapted to cover an end surface and an adjacent portion of a sidewall of a cylindrical body, comprising:

(A) a round fabric portion made of woven coated polyethylene having a thickness of approximately 12 mils and having a coating of polyethylene of 1.75 mils on each side;

(B) a substantially rectangular fabric skirt portion, made of woven coated polyethylene having a thickness of approximately 6 mils and having a coating of polyethylene having a thickness of approximately 1 mil on each side;

(C) a hot air welded region joining an upper edge of the fabric skirt portion to a perimeter edge of the round fabric portion, thereby forming a three-dimensional coil cap;

(D) a hot air overlap weld joining the upper edge of the fabric skirt adjacent to a first end of the fabric skirt to the upper edge of the fabric skirt adjacent to a second end of the fabric skirt to a segment of the perimeter edge of the round fabric portion; and

(E) a crimp weld joining the first end of the fabric skirt to the second end of the fabric skirt.
