Abstract
A form for shaping a coat sleeve is a Plexiglass tube with a re-entrant, oval, elongated hoop having a pair of generally straight side portions that generally conform in shape with front and back crease lines of the sleeve. Between the side portions are semi-circular end portions; an end portion proximate the shoulder has a greater radius than the end portion proximate the wrist. The two semi-circular end portions are approximately tangent to the ends of the side portions abutting against them so that there is a smooth transition between each of the side and end portions. Because the tube is Plexiglass, it has spring properties that cause the hoop to return to its original configuration if the hoop is deformed less than the elastic limit of the Plexiglass. The outer edges of the side portions are spaced from each other by more than the separation between the front and back crease lines of the sleeve interior so that the side portions exert outwardly directed forces against the crease lines. The hoop is formed by heating the rod over a rigid mold to provide the rod with an inherent memory of the original molded configuration. The ends of the tube are secured together by a plug havin…
