Yarn joining device and handy splicer

Abstract

The present invention provides a yarn joining device for joining two yarns (Ya,Yb) with the tail ends (eo) thereof aligned in the same direction. The yarn joining device reduces the size of the joint portion of the yarns even if the yarn joining is successively performed, and also adjusts the yarn joining length, and thereby forms the joint portion of yarns uniformly and reliably. In the yarn joining device for joining tail ends of two yarns with the tail ends aligned in the same direction, loosening and twining of the tail ends of the yarns is performed successively by a single air jet nozzle (2).

Description

technical field [0001] The present invention relates to a splicing device for splicing the yarn ends of two yarns, in particular to a splicer type splicing device in which the yarn ends of two spliced ​​yarns are aligned in the same direction. A splicing device and a portable splicer constructed so that the splicing device can be transported. Background technique [0002] As known in the art, conventional jointing devices include a jointing device called a knotter and a jointing device called a splicer. The former forms a knot and joints; the latter combines two yarns in advance. The yarn end part is untwisted, and the yarn end part is overlapped in the opposite direction in the joint hole, and the compressed fluid (compressed air, etc.) The end parts rotate and vibrate to intertwine (环み合ゎせ) and joints. [0003] Among the above-mentioned piecing devices, in the piecing method performed by a piecing device called a knotter, the knot portion protrudes along the entire circum...
