Abstract

A splicer includes a splicing head into which the two yarn ends are introduced through an inserting slot into a turbulence chamber. The turbulence chamber is formed from two juxtaposed frustum-shaped chambers interconnected by a connecting slot. A pressure medium is tangentially introduced through one opening into each chamber for forming the splice and the flow is guided in a lemiscate-like path through the two chambers. As a result of the two oppositely directed pressure medium flows, the two yarn ends are axially centrally fixed, while the two pressure medium flows escape in the direction of the larger chamber ends and thereby subject the yarn ends to a turbulent and twisting actions, so that a joint is formed having no projecting yarn ends and no weak points due to the reduced yarn twist.
