Control device for use in yarn traverse apparatus, has computation mechanism for computing rate of motion of guidance, where rate of motion is constant if guidance arrives at target point of reversal and corresponds to point of reversal

摘要

The device (80) has an inflow pattern provision mechanism for providing an inflow pattern, which indicates a relationship between a time and a target rate of motion of yarn guidance (33). An inflow drive control mechanism controls operation of a yarn guidance driving device (44) based on the rate of motion, which is computed by an inflow desired speed computation mechanism. The target rate of motion of the yarn guidance is adjusted to be constant if the yarn guidance arrives at a target point of reversal and corresponds to the target point of reversal.
