Edge weaving device of weaving machine

The invention relates to an edge weaving device of a weaving machine, in particular to an edge weaving device of the weaving machine for weaving leno edges. The edge weaving device comprises an upper yarn guide and a lower yarn guide, wherein the upper yarn guide vertically swings and also transversely swings intermittently, and the lower yarn guide vertically swings. The upper yarn guide and the lower yarn guide vertically swing to form a back-and-forth crossed opening identical to the cloth fell size and the opening time of the weaving machine, accordingly two edge weaving yarns form a leno weave in the crossing changing process without leno healds, and therefore weaving motion of the weaving machine is simplified, reciprocating motion of a motor is avoided, control programs of the motor are greatly simplified, service life of the motor is prolonged, rotating speed of the weaving machine is greatly improved, and the edge weaving device is suitable for a new generation of water spray high-speed weaving machine. The edge weaving device is simple in structure and compact and stable in transmission, reduces fault rate of the weaving machine, greatly shortens the stroke of an edge weaving mechanism, accordingly shortens the yarn reciprocating motion path, is favorable for controlling yarn tension, reduces yarn breaking, improves the production efficiency of the weaving machine, and meets market demands.
