Abstract
A splicing head has a turbulence chamber which is circular in cross section. The turbulence chamber is cylindrical or has a cylindrical center portion and conical outwardly enlarging end portion, and an insertion slot. Air inlet passages open into the cylindrical portion along tangents and in opposite directions so that air under pressure through the passages creates circumferential flow in opposite directions. Air is supplied alternately to the two passages, creating oppositely alternating air currents in the chamber, thereby twisting and joining thread ends inserted through the slot into the chamber without having overtwisted or untwisted portions.
