ABSTRACT:
Apparatus for dispensing particulate material has a substantially enclosed rigid housing with longitudinally disposed walls and parallel side walls having an opening in the housing for dispensing particulate material therefrom and a flexible sheet-like inner liner conformable to at least some of the longitudinal walls of the housing, one end of which is attached to a portion of the housing the other end of which is attached to a take-up roll for the inner liner which conforms to the longitudinal walls when the housing is filled with particulate material. The portion of the housing to which the inner liner is attached, the take-up roll and the dispensing opening are disposed relative to each other such that as the sheet-like inner liner is taken up by the take-up roll the particulate material is transported by the inner liner toward the dispensing opening and dispensed therethrough. In a preferred embodiment, the particulate dispenser is a developer housing for an electrostatographic printing machine.
