Abstract (en)

[origin: EP2083104A2] A weft cutting device for a loom includes a fixed cutter blade (1), a movable cutter blade (2) which is rotatable, and an urging member (5) which causes the fixed and movable cutter blades (1, 2) to be in contact with each other. The fixed and movable cutter blades (1, 2) respectively include edge sections (12, 22) and base sections (13, 23) which continue from the edge sections (12, 22) and which include a rotational center. The base section (13, 23) of at least one of the fixed and movable cutter blades (1, 2) includes a projecting portion (16) which projects toward the other one of the fixed and movable cutter blades (1, 2) in an area which is on a side opposite to the corresponding edge section (12, 22) with respect to the rotational center and which constantly faces the other one of the fixed and movable cutter blades (1, 2) while the movable cutter blade (2) rotates. The fixed and movable cutter blades (1, 2) are caused to be in contact with each other by the urging member (5) at only two positions including a position of the projecting portion (16) and a position corresponding to edges (11, 21) of the edge sections (12, 22).
