US Classification:

156 71, 156 82, 156212, 156468, 156497, 156498, 156577

Abstract:

A tape placement head for applying thermoplastic tape to an object includes a heated feeder which guides the tape/tow to a heated zone. The heated zone has a line compactor having a single row of at least one movable heated member. An area compactor is located in the heated zone downstream from the line compactor. The area compactor includes a plurality of rows of movable feet which are extendable toward the tape/tow different distances with respect to each other to conform to the shape of the object. A shim is located between the heated compactors and the tape/tow. A chilled compactor is in a chilled zone downstream from the heated zone. The chilled zone includes a line chilled compactor and an area chilled compactor. A chilled shim is mounted between the chilled compactor and the tape/tow.

Filed:

Feb 1, 1991

Appl. No.:

7/649354

Inventors:

Mark B. Gruber - New Castle DE

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

B65H 8100

US Classification:

156430

Abstract:

A consolidated structure with less than 6 percent void content is formed from a plurality of thermoplastic impregnated yarns traverse wound on a rotating mandrel by feeding the yarns under tension simultaneously from a source of supply to a traversing carriage as adjoining flat tapes. The tapes then move successively through a preheating section, a heated circular guide and a contact portion heating source, all on the carriage, before being laid down in a predetermined path on the mandrel.

Inventors:

Mark B. Gruber - New Castle DE

Assignee:

E. I. DuPont De Nemours and Company - Wilmington DE

International Classification:

B32B 3126

US Classification:

1562722

Abstract:

An advancing, reinforced, thermoplastic tape is pressed on a partially built, composite structure as the mating surfaces are heated to the melting point by a beam of high temperature, radiant energy. The center of the beam is directed at the structure, in advance of the nip between the tape and structure.
