  • Patent number: 4251975
    Abstract: An apparatus for stuffing cushions, mattresses, and the like. The apparatus includes a cantilevered hollow support with multiple perforations in its upper wall and selectively operable means for evacuating air from the hollow support. Cushion stuffing material is placed on the support and covered with an air impervious film advanced from a supply member carried by the apparatus and cut by a cutter adjustably mounted on the apparatus. The film closes exposed perforations of the support which are not covered by the stuffing material. The apparatus is used to evacuate the air from the stuffing material, thereby shrinking the material to allow the rapid application of a cover over the stuffing and support, followed by withdrawal of the cover and contained stuffing from the support.
