Abstract:
An arrangement of a textile machine and a device for controlling a feed of a yarn (11) fed to said textile machine (10), said yarn having a tension and a velocity, said device for controlling the feed of said yarn having a control unit (36) acting on adjustment actuators which operate on stitch forming members (33), said device comprising means (18) for ascertaining a first yarn parameter between said tension and said velocity and measuring means (3, 12) for measuring a second yarn parameter between said tension and said velocity, said ascertaining means (18) and measuring means (3, 12) are both operatively coupled to a casing (2) of the device (1) and are both connected to controlling and regulating means (20) for controlling and regulating said first and second parameters, said control and regulating means (20) continuously measuring values of both said parameters during the feed of the yarn (11) to the textile machine and comparing at least a first of these parameters with a predetermined homogeneous value and regulating said first parameter so as to maintain it constant, said controlling and regulating means (20) being connected to the textile machine control unit (30), the control unit (30) acting on the stitch forming members (33) via said adjustment actuators on the basis of the controlled second parameter value detected by the controlling and regulating means (20) in order to regulate the value of the second parameter, the controlling and regulating means (20) and the textile machine control unit (30) providing closed-loop control of a machine production process.
