Methods and apparatuses for separating glass ribbons

A method of separating a glass ribbon comprising:

• traversing the glass ribbon along a travel path past a glass cutting device and through a severing zone and along a travel direction after exiting the severing zone;
• introducing an acoustic wave into the glass ribbon with an acoustic transmitter positioned in a first direction from the severing zone;
• detecting a presence of the acoustic wave in the glass ribbon with an acoustic receiver positioned in a second direction from the severing zone that is opposite the first direction;
• inducing separation of the glass ribbon with the glass cutting device into an upstream portion and a downstream portion;
• detecting separation of the glass ribbon in the severing zone when the acoustic wave that was introduced to the glass ribbon is interrupted at the acoustic receiver;
• and
• modifying a conveyance direction of the glass ribbon toward a manufacturing component that is positioned in a downstream direction from the severing zone subsequent to detection of separation of the glass ribbon.
