Abstract
Yarn portions, particularly yarn ends, are joined together without using a knotting technique by positioning the yarn portions alongside each other and introducing such portions through an inlet of apparatus having two passages extending separately away from the inlet. Fluid flow is directed alternately along one then the other of the passages so as to move the yarn portions backwards and forwards between two passages so as to cause the yarn portions to be joined or spliced together.
Claims15
A method of joining yarns comprising the steps of positioning portions of the yarns alongside each other, introducing said portions into apparatus having an inlet for said portions, and exposing said yarn portions within said apparatus to a fluid flow to effect joining of said yarn portions wherein said apparatus has two passages in communication with and extending away from said inlet and the fluid flow is directed alternately along one then the other of said passages in a direction away from said inlet such as to cause said yarn portions to be drawn alternately along one then the other of said passages.
Yarn joining apparatus comprising a chamber with a yarn inlet thereto through which yarn portions arranged alongside each other can be introduced into the chamber, and a pressure fluid inlet to said chamber, wherein first and second passages are in communication with and extend away from said chamber, such that pressure fluid from said inlet can flow into one or the other of said passages, and diversion means is provided which is operable to effect diversion of said pressure fluid flow alternately to one then the other of said passages.
