Device for driving lances on looms without shuttle, essentially characterized by being constituted, on each side of the loom, by a continuous transmission, based on pulleys and transmitting belt, or similar, on which rides a clamp in "C", open and grooved, which takes the terminal of the corresponding lance together and moves together with the belt through the action of blocks housed in their grooves, and related by an axis embedded in that belt, causing different directions of movement and speed in said lance, which also combines the action of the drive shaft, which receives its movement from an accelerating mechanism that, by causing accelerated and/or delayed actions in the lance, eliminates dead spaces allowing shorter length of it.
