Dobbies for forming the shed on weaving looms

摘要

The present invention relates to dobbies of the type in which each double swinging lever is controlled by two pulling hooks cooperating with pulling knives with reciprocal movement. Each non-selected pulling hook in each pair is raised away from the associated pulling knife by a stirrup coupled to a vertical rod having a gripper at its upper end, the gripper being selectively coupled to a raising knife under the control of the reading mechanism. The raising knife is raised or lowered by a vertical slide mechanism which is coupled directly by a connecting rod to a lowering knife of the dobbie, so that the slide mechanism and raising knife move up and down synchronously therewith. The invention finds particular application in the textile industry.
