Abstract (en)
[origin: EP2644550A1] Device for tensioning a winding thread (2) in textile machines comprising a plurality of stationary deviator elements (22, 54) and a plurality of displaceable deviator elements (27, 47) arranged like a comb facing one another in a staggered and opposed manner so as to form a tortuous path for the thread that passes through the device, in which such deviator elements are provided with sliding elements (38) elastically contrasted to move forth and back against the thread, each sliding element (38) being capable of moving independently from each other, in which the tortuousness of the path is adjusted with a mobile device (26) that modulates the load of the elastic elements (39, 49) working in contact with the thread, to obtain the desired tension in the thread in outlet from the thread tensioning device.
