Abstract
An adaptive hot melt feed system includes a melt system, a feed system, a gas control device, a sensor, and a controller. The melt system includes a heated vessel. The feed system is configured to deliver a solid material to the vessel of the melt system for melting. The gas control device is configured to control a supply of gas provided to the feed system to drive the solid material from the feed system to the melt system. The sensor can be configured to detect an amount of material in the vessel of the melt system. The controller is in electronic communication with the gas control device and is programmed to signal the gas control device to vary the supply of gas to the feed system based on a fill metric determined by the controller.
