A method and an apparatus are described for the stress testing of glass containers which are arranged hanging, by impulse action on the bottom of the container through the adjustable action of force on an impacting rod resting on the bottom of the container. For the action of the force, an adjustable source of energy is used which may comprise an eccentric, an ultrasonic transmitter, a magnetic actuating drive or the like, which acts on the end of the rod, resting on the bottom of the container, remote from the bottom of the container. The shaking exerted on the glass container during subsequent filling can be simulated by the action of the force which is adjustable in duration and/or amplitude, so that glass containers suspected of breakage can be eliminated by the stress test before being filled. The action of force can be proportioned in a simple manner so that optimum test vibration values can easily be adjusted. |
