PROCESS AND DEVICE FOR MANUFACTURING A COMPOSITE STRAND

The process for fabricating a composite thread (6) comprises blending the thermoplastic filaments in the form of a sheet into a cluster (2) or a sheet of glass filaments, and stretching, heating and projecting the thermoplastic filaments before the penetration of the cluster or sheet of glass filaments. The composite thread is formed by the blending of continuous glass filaments (24) emanating from a spinneret (1) and continuous filaments of thermoplastic organic matter emanating from a spinning head (7). The thermoplastic filaments are projected on a moving support. The process for fabricating a composite thread (6), comprises blending the thermoplastic filaments in the form of a sheet into a cluster (2) or a sheet of glass filaments, and stretching, heating and projecting the thermoplastic filaments before the penetration of the cluster or sheet of glass filaments. The composite thread is formed by the blending of continuous glass filaments (24) emanating from a spinneret (1) and continuous filaments of thermoplastic organic matter emanating from a spinning head (7). The thermoplastic filaments are projected on a moving support at a speed higher than the scrolling speed of the moving support. The blending is effected by the projection of thermoplastic filaments between a coating roller (4) and a filament gathering device. The speed of the thermoplastic filaments during the projection is same as the speed of the stretching of glass filaments. The support is a drum and the blending of filaments is carried out on a generator of the drum. An independent claim is included for a device for fabricating a composite thread.
