ABSTRACT:
An apparatus for manufacturing a strand composed of organic filaments and glass filaments for use in the production of composite materials. This apparatus comprises at least one die, which is supplied with molten glass, and at least one drawing head, which is supplied under pressure with organic thermoplastic material, and from which are simultaneously drawn continuous filaments that are combined to form a composite strand. The drawing head comprises a central passage through which filaments of glass are drawn, and is shielded by a hood. The top of the hood includes an opening situated in the centerline of the passage, and the bottom of the hood is formed of a wall which surrounds the drawing head and extends below the level of the bottom of the head. The drawing head is connected with a device for cooling the organic filaments.
