ABSTRACT:
A high-productivity bobbin winding method comprising a variable-duration intervention cycle for restoring yarn continuity. The cycle is divided into two parts, of which a first part is devoted to braking the bobbin and a second part is devoted to joining the yarn, between the commencement of the two parts there being interposed a delay which varies as a function of the time measured for the bobbin to come to rest during the preceding intervention cycle. By reducing the stoppage time for rejoining the disconnected yarn, unproductive time during the winding operation is shortened.
