摘要:
The present invention introduces a yarn y that is unwound from a supply bobbin 1 into a control member 3 for controlling the propagation of twisting toward a supply bobbin, then introduces the yarn into a friction-disk-type false twister 4 to suppress fluff, and finally controls the yarn feeding speed in the friction-disk-type false twister in order to control the yarn tension. The present invention can reduce the amount of fluff on a yarn that is unwound from a supply bobbin and wound around a winding package and control the yarn tension. Therefore, the present invention eliminates the needs for a special device for controlling the tension.
摘要:
The present invention enables an unfinished package for which a winding process has been interrupted during a rewinding operation to be easily finished under original conditions to obtain a package of a predetermined winding length. An automatic winder has a frame control device 4 comprising winding units 1 each of which executes a winding process of unwinding a spun yarn Y from a supplying package B to wind the yarn into a winding package 9, a process starting and stopping function to start and stop the winding process, an interruption information control section 75 that operates when the winding process in a winding unit is interrupted during a rewinding operation, to acquire and store operational information provided to this winding unit immediately before the interruption, and a restoring section 76 that operates when the interrupted winding process is restarted, to read the operational information to cause the winding unit 1 to restart the winding process on the basis of the operational information (Fig.1).
摘要:
The present invention more quickly prevents the production of defective packages by inspecting the package during formation. Specifically, a yarn detection sensor that detects the existence of yarn positioned on the outermost layer of the package is arranged. The package is inspected by a positioning of the yarn detection sensor such that the detection light of this yarn detection sensor passes close to the contact line of between the package and drive drum, and moreover along the side where the yarn is guided onto the package.
