WEFT FEEDING APPARATUS OF WEFT MAGAZINE OF WEFT KNITTING MACHINE

摘要

PURPOSE: To feed a weft thread under tension of fine variance and max tension by calculating a drive speed of a servo motor while incorporaing a spindle data and the data of a set motion mode. CONSTITUTION: The data of a motion mode, which has the speed initially set/ selected by the number of rotation of a spindle 17, is called out from a memory S, at this time, a start point corresponds to a specified position of the spindle 17. The position state target value of a weft insertion carriage 11 generated based on the above and the position state present value calculated from a position alarm 20 are compared, the drive speed of a servo motor 9 is decided or corrected correspondingly to a control error.
