    • 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.
    • 用于分配颗粒材料的设备具有基本上封闭的刚性壳体,其具有纵向设置的壁和平行的侧壁,其在壳体中具有用于从其中分配颗粒材料的开口,以及适合于壳体的至少一些纵向壁的柔性片状内衬 其一端附接到壳体的一部分,其另一端附接到当壳体填充有颗粒材料时符合纵向壁的内衬的卷取辊。 内衬的安装部分,卷取辊和分配口相对设置成使得当片状内衬被卷取辊吸收时,颗粒材料为 通过内衬输送到分配开口并通过其分配。 在优选实施例中,颗粒分配器是用于静电印刷机的显影剂外壳。
