ABSTRACT:
A method and apparatus for controllably delivering discrete loose fill dunnage particles from a supply to a packaging site and for applying an additive to at least a portion of an exposed surface on a plurality of particles to cause abutting particles to adhere to each other. The apparatus consists of: a conduit having an inside wall surface defining a conveying path for loose fill particles, an inlet end communicating with the loose fill particle supply, and an outlet end for discharging loose fill particles conveyed from the supply through the conduit to the packaging site; a nozzle for producing a shower of additive through which a plurality of loose fill particles conveying between the supply and the packaging site pass; and structure for delivering a pressurized additive through the nozzle so that the additive is directed by the nozzle in a pattern adjacent to the outlet end of the conduit.
