Abstract
The high pressure cartridge feed system of the invention includes a cradle that supports the material cartridge so that the cartridge will not fail at the high dispensing pressures. A powered ram assembly drives a ram head into the cartridge to create the high dispensing pressure. The cartridge is supported on all sides to prevent failure. A smooth connection fitting is provided to allow cartridges to be quick changed. The cradle is pivotably mounted to allow the cartridge to be loaded in a substantially horizontal position. In one embodiment, the cradle is removable.
