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.

Abstract: The thermo-bonding interlining is a nonwoven covered on one face with dots of thermo-bonding resin. According to the invention, the nonwoven is a web, containing no binder or thermo-fusible fibers, whose weight per square meter is between 50 and 150 g, and which is produced from filaments in a thermoplastic material, such as polyester; the mean diameter of the filaments is between 3 and 5 .mu.m, and preferably 90% of the filaments have a diameter comprised between that range; intermingling of the filaments is obtained by streams of high pressure fluid, such as streams of water at pressures of 40 to 80 bars.
