ABSTRACT:
The return device for the projectiles of a gripper projectile weaving machine has an end position brake employing an abutment in the form of a piston which is guided in the cylinder and which experiences the light pressure of a restoring spring. The ratio of the mass of the projectile to the mass of the piston at a given projectile speed is such that the projectile stops immediately upon striking the piston. The piston does not experience local wear over extended periods of time and obviates any need for a means to prevent a bounce-back of the projectile.
