ABSTRACT:
Apparatus for the formation of laminar, fiber-reinforced resin composite tubes of elbow shape. The apparatus, a filament winding machine, is employed by winding a continuous strand, or plurality of strands, of a resin-wetted yarn, roving, or filament about an elbow-shaped mold. The apparatus combination is constituted of a hollow shaft of curvilinear shape on which an elbow-shaped mold can be telescopically mounted. The two terminal ends of the hollow shaft can be journalled in place and the hollow shaft rotated thereabout. The combination also includes a sprocket-supported chain and connecting cable, the cable portion of which passes through the interior of the hollow shaft. The two terminal ends of the cable can be connected to the mold when the latter is mounted thereon so that reciprocal movement of the chain and cable can oscillate the mold upon the hollow curvilinear shaft as the shaft is rotated. Motor means are provided for producing both rotational and translational motion of the mold to wind the resin-impregnated filament perpendicularly to the axis of the mold while butting each row of applied filament side to side one row against another as the resin-impregnated filament is drawn from a supply source by rotation of the curvilinear hollow shaft, and translational motion of the mold.
