<p>A pressure applying device for a yarn drawing frame in which yarn drawing frame a plurality of yarn drawing units are arranged above a framework (11), with each yarn drawing unit being constituted by a drawing shaft (13) and a plurality of drawing or laminating discs (14) arranged as disc pairs connected with each other by a central hub (15), urged against said drawing shaft and revolving inside side guides inside which the yarn runs. Each individual device comprises a support element for an actuator means, which is constrained to the framework (11), and a lever (19) which is hinged on, and swings relatively to, said framework, and which gets engaged in a portion thereof above said hub (15) and which, thanks to the thrust applied by the actuator means, is kept into contact with said hub (15). When the yarn drawing frame is switched off, the disengagement of the actuator means causes the discs (14) to be moved away, and disengaged, from the drawing shaft (13). <IMAGE></p> |
