US Patent:

44486243, May 15, 1984

Filed:

Mar 11, 1983

Appl. No.:

6/474441

Inventors:

Robert C. Webber - Marietta GA

Assignee:

Lockheed Corporation - Burbank CA

International Classification:

B65H 8100
B41B 1100

US Classification:

156175

Abstract:

An apparatus and method is disclosed for the fabrication of cylindrical structures (26) by filament winding of resin impregnated filaments around a novel cylindrical mandrel assembly (10) whereby the mandrel assembly (10) and fabricated cylindrical structure (26) are easily separated after curing of the resin impregnated materials. The invention utilizes an inner, hollow cylindrical mandrel member (11) onto which a metal cable (12) is wound over afterwhich segmented outer mandrel sections (13) are connected to the inner mandrel member by fastener devices (20) installed from the inner side of the inner mandrel member (14). The resin impregnated filament is then wound over the outer mandrel segments (13) and cured in a conventional manner. After curing, the fasteners (20) are removed from the inner side of the inner mandrel (11), and the cable (12) is removed by pulling it from one end of the mandrel assembly (10). With the cable (12) removed, clearance is provided so that the inner mandrel (11) can be removed from the outer segmented mandrel (13), and once the inner mandrel (11) is removed, the outer, segmented mandrel (13) is disassembled and removed inwardly from contact with the cured filament wound cylinder (26).

International Classification:

B05D 118
B05D 302
B05D 312
B05D 512

US Classification:

427120

Abstract:

A method of applying substantially consistent and uniform coatings of a corrosion preventive compound to metallic cable lengths is disclosed which involves the immersion of the cable into a liquid coating compound of controlled viscosity followed by wiping the cable with a compound-containing material upon withdrawal of the cable from the compound.
