ABSTRACT:
The device comprises a number of threading tubes 2 oscillatably mounted on a thread guide rail 5 provided with an oscillatory motion. Each theading tube 2 is movable against the action of a first return spring 6, upon command of an actuation cable 9 guided within a sheath 10 and connected to a control plate 19 selectively operable in synchronism with the thread guide rail 5. Each sheath 10 has one end 10a which is fixed with respect to the thread guide rail 5 and a second end 10b connected to a fixed support 11, a second return spring 15 being interposed therebetween, the stiffness of said second spring 15 being greater than that of the first return spring 6. A preloading plate 17fastened to the fixed support 11 acts upon locating elements 13 in order to keep said second return springs in a preloading condition.
