Abstract (en)
[origin: WO8202217A1] A method of driving a heald when flexible transmission members (3a, 3b), such as ropes or the like, connected to the shedding levers of a negative dobby machine, negative cam machine, etc. are provided above a heald frame (11). The flexible transmission members (3a, 3b) and the heald frame (11) are connected via operation levers (4a, 4b) arranged at the side or above the heald frame (11) and a connecting rod (8) or the like, so that the spring tension acting on the heald frame (11) is small and the members (3a, 3b) and an operation member (2) for the negative dobby machine body, negative cam machine body, etc. less wear in case that the tension of the falling warp is larger than the tension of a lifted warp. The heald frame (11) is lowered by the tension of the members (3a, 3b) and raised by the force of spring (13) arranged above or beside the heald frame (11).
