Abstract

An apparatus for communicating false twist to produce ripples in the filament yarns, comprising: a first endless belt, driven to move in one direction, under tension, and having a region that extends straight between its spaced pulleys supporting it, said region presenting a contact surface, on which the filamentary threads are brought into contact, successively, as they are introduced into it, a second endless belt, driven to move, subjected to tension, in a vertically spaced position of the first belt in the opposite direction to that of the first belt and which has a region that extends straight between its spaced pulleys that support it, the mentioned region of this second belt being parallel to the corresponding region of the first belt, and presenting on that side, a surface that can come into pressure contact, successively, with the filamentary threads that have passed the sup contact surface, of the straight extending region, of the first belt, means for detecting fluctuations in the tension of the filament yarns, said means being provided on the exit side of the filament thread, means for adjusting the positions of the input and output guides of the filamentary wires, these means being operatively associated with the mentioned means for detecting voltage fluctuations, and, means for adjusting the parallel distance between the straight extending regions of the first and second straps, these means being provided, in the base frame, of the apparatus.
