Abstract
A marble feed system is disclosed for feeding glass marbles into a marble melt glass fiber forming bushing. The system comprises a storage container or hopper, a marble pre-melter, a glass fiber forming bushing, and a chute connecting the container or hopper to the pre-melter. The chute is specifically designed to prevent blockages of glass marbles due to bridging, oversized marbles and broken marbles during feeding. The novel design enables pure gravity flow of glass marbles without the need for external vibration of the feed system or other means of force feeding the marbles through the system.
