Herein is described a process for drying wet glass fibre forming packages, the process comprising: providing a wet glass fibre forming package comprising a strand of glass fibres with an aqueous sizing applied to the glass fibres; and subjecting the wet glass fibre forming package to microwave radiation having a frequency in the range of about 750 to about 1050 MHz.

The automatic strand take-up installation comprises at least one gripping member () for taking hold of at least one strand coming from a bushing (), the gripping member being guided by a single conveying loop () to the vicinity of a chopper (). One system for maneuvering the gripping member allows the gripping member () to be opened and closed in such a way as to release said strand at the chopper ().

Automatic strand take-up installation

A process for manufacturing a composite yarn including continuous glass filaments intermingled with continuous organic thermoplastic filaments and an apparatus for implementing the process. The continuous glass filaments come from a bushing and are separated into plural sheets. The continuous organic thermoplastic filaments come from a spinning head and are separated into plural sheets. The thermoplastic filaments are thrown into the glass filaments so as to mingle them, in a ratio of at least one sheet of thermoplastic filaments in each sheet of glass filaments, the mingled filaments then being gathered into at least one composite yarn.

Method and device for producing a composite yarn

A process for manufacturing a composite yarn including continuous glass filaments intermingled with continuous organic thermoplastic filaments and an apparatus for implements the process. The continuous glass filaments coming from a bushing and are separated into several sheets. The continuous organic thermoplastic filaments come from a spinning head are separated into plural sheets. And the thermoplastic filaments are thrown into the glass filaments so as to mingle them, in a ratio of at least one sheet of thermoplastic filaments in each sheet of glass filaments, the mingled filaments then being gathered into at least one composite yarn.

A process for manufacturing a composite profile based on a thermoplastic organic material reinforced by reinforcing fibres includes making a multiplicity of continuous reinforcing yarns come into contact with a thermoplastic organic material and shaping the composite profile. Continuous yarns based on continuous glass fibres and on a first thermoplastic are brought together to be parallel and at least one consolidated tape is formed by heating them, in which tape the reinforcing fibres are impregnated with the first thermoplastic. The at least one tape is introduced into a die sized to the cross-section of the profile and at least one second molten thermoplastic organic material is simultaneously introduced into the die in contact with the tape, to obtain a profile of at least one second thermoplastic organic material reinforced by the at least one tape.

Device for sheathing a filiform material with a molten substance

An apparatus and process for the production of a composite thread of glass and of organic material wherein continuous filaments of thermoplastic organic material are mixed in the form of a sheet with a bundle or sheet of glass filaments, with the speed of the thermoplastic filaments during their penetration into the bundle or sheet of glass filaments being greater than the speed of drawing of the glass filaments.

Process and device for making up a composite thread

The present invention relates to a process for manufacturing a composite thread formed of a plurality of filaments combined with a thermoplastic organic material, which consists in mechanically entraining a thread in a device mounted in the manner of a cross head at the end of an extruder and injecting the material in the direction of the thread and concentrically thereto at a constant maximum radial pressure of less than 50 bars.

Extrusion head for producing yarns from a material which has been heated

The process of manufacturing a thermoplastic organic material containing reinforcing fibers and optionally mineral materials and organic additives by combining the fibers and materials in an extruder, and introducing at least some of the organic material into the extruder in the form of continuous filaments or fibers.

Process for manufacturing a composite product by moulding

Drawing, from a first installation, organic filaments in the form of one or more layers which converge toward a same point, and drawing, from a second installation, glass filaments which are joined together to form at least one strand. Guiding structure is provided to laterally introduce the glass strand into the area defined by the organic filaments before it is combined with the filaments at their point of convergence. A blowing device (48, 36) is also provided either outside or inside the area defined by the organic fibers.

Apparatus for manufacturing a glass and organic composite strand,

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.
