Abstract
A winding control device for a take-up winder that can reliably and precisely eliminate the slips of a contact roller rotated in contact with a bobbin holder used in a spindle-driven winding machine for synthetic yarn is described. The winding control device includes an induction motor IM3 which supplements the driving of the contact roller CR which rotates in contact with a package P. A counter force detector 7, 8 or 13 which detects the counter force created by the rotation of the contact roller against the bobbin holder, and a control part eliminates slips by adjusting the relative rotation speeds of the bobbin holder BH1 and the contact roller CR based on the output of the counter force detecting means 7, 8 or 13.
