Abstract
A yarn engaging element is manipulated from a non-operating position through the winding path of a textile winder to engage and guide a yarn end to be spliced to a splicer. After splicing, the yarn engaging element returns at a controlled rate to release the spliced yarn at the winding path, with the release being sufficiently gradual to allow the resumption of winding to maintain tension in the spliced yarn as it moves from the splicer to the winding path, thereby avoiding sufficient slack in the spliced yarn to create kinking and yarn breaking. The yarn engaging element is manipulated by a four-link linkage controlled by a piston-cylinder mechanism or by a camming mechanism.
Claims14
In a method of automatically splicing yarn ends on a textile winder wherein yarn ends are picked up from a supply bobbin and a winding package and positioned at a splicer for splicing out of the normal path of winding with the spliced yarn then being released to assume the winding path under the tension of winding, the improvement comprising:
- guiding said spliced yarn from said splicer to said winding path during start-up of winding subsequent to splicing while controlling said guiding to maintain the spliced yarn under winding tension without substantial slack as it is guided from said splicer to said winding path, thereby minimizing kinking and yarn breaks.
In a textile winder of the type having means for automatically splicing yarn ends and means for picking up yarn ends from a supply bobbin and a winding package and positioning said yarn ends at said splicing means out of the winding path, the improvement comprising:
- means for guiding said spliced yarn from said splicing means to said winding path during start-up of winding subsequent to splicing and means for controlling said guiding means to maintain the spliced yarn under winding tension without substantial slack as it is guided from said splicing means to said winding path, thereby minimizing kinking and yarn breaks.
