    摘要: A first braking plate (32) is adapted to be coaxilly fixed to a delivery end of a drum (12). A second braking plate (40) is coaxially biased against the first one by elastic means (48) operatively engaged between the second braking plate (40) and an abutment (50). The yarn (Y) runs between the braking plates (36, 44), thereby receiving a braking action by friction depending on the pre-load of the elastic means. The abutment (50, 150) is operatively connected to a motor (54, 154), via rotary-to-translatory motion conversion means (58a, 64a, 150a, 151), for shifting in a direction such as the pre-load is varied. The motor (54, 154) is driven by a control unit (CU, CU') which modulates the pre-load in such a way as to maintain the tension of the yarn (Y) substantially constant on a desired level, on the basis of a signal generated by a tension sensor (70, 170) interacting with the yarn unwinding from the feeder.

    摘要: The yarn tension is modulated by a yarn-braking device (20) controlled by a control unit (CU) which receives signals of measured tension (T_meas) from a tension sensor (22) and compares them with a reference tension signal (T_ref) in a control loop (CL) having a proportional-integral controller (PI) generating a braking signal (BI) which minimizes the difference ( e ) between the measured tension and the reference tension. As long as the reference tension (T_ref) remains unchanged, a first set of coefficients (Kps and Kis) is used in the control loop (CL) causing the control loop (CL) to have a relatively slow behaviour in relation to the error-compensating action. When a change in the reference tension occurs, the system switches to a second set of coefficients (Kpf and Kif) causing the control loop (CL) to have a relatively fast behaviour. The second set of coefficients (Kpf and Kif) is maintained as long as the difference ( e ) between the second value of the reference tension (T'_ref) and the measured tension (T_meas) remains greater or equal to a predetermined minimum value ( e_min ), then the system switches again to the first set of coefficients (Kps and Kis).

    摘要: The feeder comprises a stationary drum (12) on which are wound loops of yam to be fed to a downstream textile machine, and a self-governing braking device comprising a hollow, frustoconical braking member (16) which is arranged in front of the drum (12) and is supported at the middle of a spider assembly of springs (18) hooked between the braking member (16) and an annular support (19). The springs (18) have a length at rest which is equal to, or higher than, the span between their hooking point on the frustoconical member (16) and their hooking point on the annular support (19). The annular support (19) is slidably supported with respect to the drum (12) along an axial direction, under control of driving means (22), for biasing the frustoconical member (16) against said edge (12r), thereby causing the frustoconical member to align to the drum, while approaching thereto, by geometrical engagement.
