Description

technical field

[0001] The present invention relates to a device for forming a shed in a loom of the Jacquard type. Background technique

[0002] In Jacquard-type weaving systems, it is known to drive in opposite phases two multi-hooks each bearing a hook adapted to move vertically via a pulley or slider and tackle mechanism, connected to the heald / harness cord. A knife box (griffe) or a frame for horizontal lifting of the knife.

[0003] It is also known, for example from EP-A-0933456, to alternately move the heddle of a Jacquard machine, using an electric rotary actuator-controlled pulley for more or less winding a cord-like element. This prior art performs the function satisfactorily, but as hitherto each actuator controlled one or a small number of heddles, requiring the use of a large number of electric actuators. If several healds are controlled by the same actuator, the relative inclination angles of the healds connected to these heddles must be small to limit frict...
