ABSTRACT:
The torsion bar firing device is provided with a striking lever having an end piece at the distal end which acts directly on the abutment face of a projectile on firing. The striking face of the end piece of the striking lever and/or the abutment face of a projectile may be formed as inclined planes or as convex, concave, or concave-convex surfaces. The direct drive of the projectile by the striking lever reduces the masses to be accelerated and braked. This advantageously influences the energy consumption and the weaving efficiency of the projectile weaving loom. The end piece may be integral with the distal end of the striking lever or may be in the form of a rotatably mounted roller of a trapezium shaped element.
