Abstract: A METHOD AND A DEVICE ARE DISCLOSED FOR IMPROVING THE COHESION BETWEEN INDIVIDUAL MONOFILAMENTS OF A COHERED YARN. THE METHOD CONSISTS IN LIMITING THE FREEDOM OF OSCILLATORY MOVEMENT OF THE INDIVIDUAL FILAMENTS AS EXPOSED TO THE ACTION OF A COHERING GAS JET, AND IS CARRIED OUT BY PROVIDING A GROOVED OR SPLINED CYLINDRICAL SURFACE IN THE AREA WHERE THE GAS JET IS ACTIVE ON THE FILAMENTS. THE DIMENSIONS, AND THE DISTANCES AT WHICH THE CYLINDRICAL SURFACE IS PLACED WITH RESPECT TO THE OTHER COMPONENT PARTS OF THE INSTALLATION ARE CRITICAL.
