Abstract

A compressed air thread splicing device for producing a knot-free thread connection by splicing includes a splicing head having a splicing channel formed therein with two at least partially open ends for receiving threads to be joined in a given insertion direction and for alternately tangling, intertwining, swirling and winding fibers of the threads around each other, the splicing head having at least one compressed air inlet orifice formed therein leading into the splicing channel, the splicing head having at least one flow-channel formed therein branching off from the splicing channel transverse to the given insertion direction between the at least one inlet orifice and one of the ends of the splicing channel, and a switchable device connected to the at least one flow channel for generating a temporally limited current in the at least one flow channel in a flow direction away from the splicing channel.
