Abstract
System for delivering air-filled packing cushions to a point of use in which a continuous string of the cushions is fed into an elongated duct with the string extending longitudinally of the duct, and an air flow is established in the duct to convey the string of cushions through the duct. In one disclosed embodiment, the air flow is created by a blower mounted externally of the duct, with a baffle plate inside the duct directing the air flow in a longitudinal direction. In a self-contained system in which the cushions are made at the point of use, the duct extends vertically, and the cushions are fed directly into the lower end of the duct by a machine which makes them. The string of cushions is discharged from the upper end of the duct into a bin from which they can be withdrawn as needed for use in cartons supported by a stand positioned beneath the bin.
