Claims

[Scope of Claim for Utility Model Registration] A yarn crossing mechanism forms the new and old yarns arranged side by side into a predetermined crossed shape, and a yarn guide hook guides the new and old yarns in the crossed shape. In the yarn tying device that connects both the new and old yarns by a knotting mechanism after forming a pre-knotted state, the yarn crossing mechanism is driven by a first yarn cross plate and a drive source to connect the first yarn cross. a first link that rotates the plate; a thread engaging claw provided on the first link; and a second thread cross plate installed at a position opposite to the first thread cross plate across the thread guide hook; a second link that is driven by a drive source to rotate the second thread cross plate; and a thread engaging pawl provided on the second link; A locking part is formed to maintain the old yarn caught and rotated by the yarn cross plate within a predetermined distance from the new yarn locked by the yarn engaging claw, and also to keep the old yarn caught and rotated by the yarn cross plate within a predetermined distance. A thread tying device for a sewing machine, characterized in that a cutter for cutting residual thread produced at knotting is arranged adjacent to a second thread cross plate.
