ABSTRACT:
A splicing head for a compressed air yarn splicing device has a splicing chamber with a yarn insertion slot opening thereinto and an arrangement by which a pair of compressed air entrance openings may be adjustabley located at differing dispositions with respect to the splicing chamber so that differing splicing air vortices may be selectively generated within the splicing chamber as required for differing yarn characteristics. A common compressed air supply with a single control valve is provided for supplying compressed splicing air to each entrance opening. In one embodiment, a plurality of entrance openings are formed in the splicing head and a shiftable slide plate having a pair of compatible openings enables selective communication between the compressed air supply and the splicing chamber through alternate pairs of the plural entrance openings. In another embodiment, a pair of the entrance openings are formed in a shiftable member mounted to the splicing head for adjustable disposition of the openings relative to the splicing chamber. The splicing head thereby eliminates the need for a plurality of interchangeable specialized splicing heads.
