Abstract
The process for manufacturing strings according to the invention is of the type comprising a step in which a thread is produced from fibres, a step in which the thread is impregnated with a resin, a step in which the impregnated thread is coated with a synthetic material to provide it with a sheath, a step in which the synthetic material is caused to be completely cross-linked, and a step in which the thickness of the sheath is adjusted. It is characterized by use of discontinuous fibres that are subjected to textile operations of intersecting and drawing-twisting. The process according to the invention makes it possible to produce strings designed to be subjected to tensile stress, in particular strings for rackets and musical instruments.
