A dispensing system using dual linear vibratory feeders, aligned along their longitudinal axes with their dispensing ends at substantially the same vertical location. The feeder trough of one feeder penetrates the structure of the other feeder, allowing them to be aligned and compactly located. Isolation mounts may be used to damp the vibration of the feeders. An optional metering pan serves as an intermediate stage which accepts supplied material and transfers it to the feeder without compaction or bridging. Resilient mounts and an adjustable mass on the pan allow the amount of vibrational energy transmitted to the pan to be adjusted independently of the energy supplied to the feeder by the vibratory motor. A counterweight may be used to shift the center of mass of the fixed portion of the feeder into alignment with that of the vibrating portion.

Pass-through dispenser system with aligned feeder troughs

A method and apparatus for simultaneously filling adjacent sides of a window spacer frame with a desiccant material is characterized by a fill head having a discharge port in communication with a desiccant chamber, a releasable clamping device for clamping the open ends of the adjacent sides in alignment with the discharge port, and the chamber is pressurized with air to force the desiccant material through the discharge port for a time interval necessary to fill the sides of the spacer frame. An air conveyor is provided to induce the flow of desiccant material from a reservoir for the purpose of periodically refilling the desiccant chamber when empty, and a filter system in the air conveyor will separate the desiccant material from the air stream while permitting the air stream to be exhausted to atmosphere during the filling operation.
