Abstract (en)

[origin: EP0690160A1] A weft inserting apparatus for a rapier loom for weaving a fabric by inserting a weft through a shed formed by warps by reciprocatively moving feeding and receiving rapier heads through the shed. The feeding and receiving rapier heads (1; 2) are each constituted by a combination of a stationary gripper member (7; 11) and a movable gripper member (8; 12) made of a magnetic material. Electromagnets (18; 19) are disposed at both ends of a sley (17), respectively, while electromagnets (20; 21) are disposed at a mid portion of the sley. The movable gripper member (8) of the feeding rapier head (1) positioned in opposition to the electromagnets (19; 21) is displaced from a weft grip position to a weft release position by controlling the magnetic action of the electromagnets (18; 20), while the movable gripper member (12) of the receiving rapier head (2) disposed oppositely to the electromagnets (19; 21) is displaced from the weft grip position to the weft release position by controlling the magnetic action of the electromagnets (19; 21). The weft insertion can be carried out with high reliability while positively protecting the weft against injury. <MATH>
