Abstract
A system for providing dunnage to packages as the packages are formed is disclosed. The system includes a dunnage forming machine having a work station for inflating and sealing plastic pouches to form dunnage units. An accumulator is positioned below the station for receiving and collecting such units as they are formed. The accumulator includes an outlet opening laterally offset from the station. A pair of counter rotating brushes having axes journaled in spaced relationship are mounted at the outlet. Each of the brushes includes circumferentially spaced bristle sets defining unit receiving spaces between adjacent sets. A motor drive is operably connected to the brushes for causing counter rotation. A unit volume sensor is provided for emitting a machine start signal when the volume of units in the accumulator reaches a predetermined low volume. A process for providing dunnage in packages being formed is also disclosed.
