ABSTRACT:
The winder is provided with thread divertor guides for both the upper and lower chucks with the angle of diversion not exceeding 120.degree.. The geometry of the winder is such that the respective chucks contact the contact member in separate sub-zones of the winding zone which are spaced apart by a narrow gap. The included angle between the imaginary lines joining the axis of each chuck in its respective rest position to the axis of the chuck when in contact with the contact member lies in a range of from 60.degree. to 175.degree.. The contact member when in the form of a friction drive roll has an external diameter of from 100 to 155 millimeters. When the contact member is in the form of a contact roll with each chuck having an independent drive, the roll may have a diameter in the range of from 60 to 80 millimeters.
