Palletized materials are delivered in controlled quantity into a pulse modulated air stream. A vortex of compressed air gates the pellets into flexible small diameter tubing for transit to a hot melt adhesive application apparatus. Pellets of different materials, sizes, and shapes can be combined in a defined ratio within several seconds of melting at the application point. Pellet delivery air can be utilized for spray application of the melted material.
