Abstract (en)
[origin: US4768728A] The tension in the rewound thread is modified in programmed manner as a function of the residual thread length still on a copy, the residual thread length being determined from the difference between the total thread length on the copy and the thread length already unwound from the cop. The total thread length on a cop is calculated from the weight of the thread and a calculation factor length per thread weight. For this purpose, the apparatus for performing the method has a weighing cell, which is connected to the control unit of the rewinding means. During the complete rewinding process, the rewinding speed can be kept close to the limit beyond which thread breaks increasingly occur.
