    摘要: A flat knitting machine that can speedily and accurately measure knitting yarn tension during knitting is provided. The flat knitting machine 1 includes: a needle bed 1B that has multiple knitting needles; a yarn feeder 2A that is attached to a rail 1R that is parallel to the length direction of the needle beds 1B, the yarn feeder 2A travelling along the rail 1R and feeding yarn (9) to a needle bed gap of the needle beds 1B; a knitting condition adjustment apparatus 5 that adjusts a knitting condition related to yarn feeding; and a knitting condition control unit that controls the knitting condition adjustment apparatus 5 based on the tension of the knitting yarn 9. The yarn feeder 2A includes a tension sensor 4 that acquires information related to the tension of the knitting yarn 9 and outputs the information to the knitting condition control unit.

    摘要: A drum (12) has a yarn (Y) wound thereon which is adapted to be unwound upon request of a downstream textile machine. A passive weft-braking device (22) exerts a predetermined, uncontrolled braking action upon the yarn (Y). A controlled weft-braking device (24) arranged downstream of the passive weft-braking device (22) is provided with a first series of comb-like arranged prongs (36) and with a second series of comb-like arranged prongs (40) inserted in an alternated configuration between the prongs (36) of the first series. The yarn (Y) runs in a zig-zag manner between the two series of prongs (36, 40) and receives a braking action by friction from them, which changes in strength depending on their relative position. A motor (46) drives the second series of prongs (40) with respect to the first one for adjusting the strength of the braking action. A tension sensor (50) measures the tension of the yarn (Y) unwinding from the drum (12) and generates a corresponding tension signal (T). A control unit (CU) controls the motor (46) by feedback based on the tension signal (T), in such a way as to stabilize the tension of the yarn (Y) on a desired level.

    摘要: A yarn conveying system for a circular knitting machine (10), includes at least one yarn conveying tray (20) and a control unit (40) electrically connected to the circular knitting machine (10) and the yarn conveying tray (20). The circular knitting machine (10) has a needle cylinder (11) and at least one yarn feeder (12) arranged annularly on the needle cylinder (11). The yarn conveying tray (20) is wound by at least two separate yarns (30) and includes a driving device (23) to drive the yarn conveying tray (20) rotating so that the yarns (30) are supplied via a yarn conveying path (R) to the yarn feeder (12). The control unit (40) generates a yarn feeding signal (S1) to the circular knitting machine (10) to control yarn feeding speed and a driving signal (S2) to the driving device (23) to control rotational speed of the yarn conveying tray (20). Thus users can operate the control unit (40) to control speed of the yarns supplied from the yarn conveying tray (20) to the yarn feeder (12).

    摘要: In a thread processing system (S), a thread delivery device (F) comprising a drum-type storage body (4) and a tensiometer (C) that contains a tensiometer element (E) is positioned upstream of an infeed device (EV). The thread is deviated by the tensiometer element (E) of the tensiometer at a predetermined deviation angle (α) and the components of the processing system (S) are positioned in such a way that the upstream and downstream thread path sections (a, b) are at least largely rectilinear. To achieve this, the axis (X) of the storage body (4) is tilted at an angle approximating to the predetermined thread deviation angle (α) in relation to the downstream thread section (b).

    摘要: The tension is modulated by a weft-braking device (20) controlled by a tension control block (TC) programmed for comparing the measured tension (T_meas) with a reference tension (T-ref), and for transmitting a braking level signal (BI) to the weft-braking device (20), which braking level signal is adapted to minimize the difference between the measured tension and the reference tension. The yarn consumption speed is calculated, then the yarn consumption speed is compared with a predetermined treshold speed, and if the calculated consumption speed overcomes the predetermined treshold value, the tension control block (TC) is enabled, while, if the calculated consumption speed is lower than the treshold value, the tension control block (TC) is disabled and the last signal generated by the latter is maintained as braking signal (BI), until the yarn consumption speed overcomes again the treshold value.
