Yarn winding apparatus

摘要

A spindle drive type winding apparatus wherein a spindle onto which a bobbin for winding a yarn thereonto to form a yarn package is inserted is driven so that a predetermined winding factor is controlled in accordance with a predetermined program. The spindle drive type winding apparatus is provided with a control device which comprises: a peripheral speed detector for detecting the peripheral speed of the yarn package and generating a peripheral speed signal; a control for controlling the rotational speed of the spindle and generating a control signal; a circuit for calculating the wound amount of the yarn package based on the peripheral speed signal emitted from the peripheral speed detector and the signal emitted from the control and for generating a radius signal; and a function generator for emitting a programmed winding signal obtained in accordance with a pattern based on theradius signal emitted from the calculating circuit. The winding factor may be a peripheral speed of the yarn package, and in this case the peripheral speed is detected by means of the peripheral speed detector. The winding factor may be tension in wound yarn, and in this case the tension in yarn is detected by means of a tension detector. The winding apparatus may be driven at a constant wind ratio or at a constant wind angle.
