Abstract (en)
[origin: EP1118569A2] Process for controlling the rotation drive of a continuous filament thread-collection system, containing a rotating drum, on which at least one rotating bobbin-holder chuck is assembled, a traversing device and a picking roll, arranged according to the thread direction, upstream of the drum, where the picking roll is kept in constant contact with the outside surface of the bobbin, which increases in diameter during the collecting phase, by means of the drum rotation drive, characterized in that: the calculation of the diameter (D) of the bobbin is obtained by the following formula: <DF>- D = Vcollection/ pi Vchuck K </DF> wherein Vcollection is the collection velocity of the picking roll, established by the operator, Vchuck is the chuck rotation velocity determined by the control drive signal of the asynchronous chuck motor, K is a constant experimental coefficient, which can have a value higher than 0.6 and less than 1; the determination of the angular position ( alpha ) of the drum is obtained by means of the calculated bobbin diameter (D) so that the rotation drive control of the collection system can be transmitted to bring the drum to the established angular position ( alpha ). <IMAGE>
