Edge slitter device for weaving yarns without slitter edges

The invention relates to an edge slitter device for weaving yarns without slitter edges of a shuttleless loom. A static blade is fixed on a waste yarn slitter seat, simultaneously a dynamic blade is hinged on the waste yarn slitter seat by a hinge pin, the static blade and the dynamic blade cooperate, a waste yarn suction tube is fixedly installed on a suction tube air inlet seat, the waste yarn suction tube is erected on an suction tube seat, the suction tube air inlet seat is also provided with an air inlet tube and a waste yarn outlet tube, the air inlet tube, the waste yarn outlet tube and the waste yarn suction tube are always kept in a communicating state, a jet assistant air inlet tube and an assistant nozzle are fixedly installed on the waste yarn slitter seat, the outlet of the assistant nozzle is aligned with the opening of the suction section of the waste yarn suction tube. The invention can remarkably simplify the loom structure, reduce running cost of the loom, lower consumption in power and mate
