ABSTRACT:
An apparatus for the centered feeding of pieces of laundry to a conveyor comprises a support for hangingly supporting a piece of laundry to be fed to the conveyor, the support is reciprocally movable parallel to the centerline of the conveyor between a first position where a front face of the support is in front of the conveyor and a second position where the front face is disposed above the conveyor. The support comprises a hollow body with a front face formed by a belt with apertures therethrough. The belt is movable transversely of the conveyor centerline and the hollow body. A vacuum source is connected to the hollow body through a valve. Application of vacuum pressure to the hollow body allows an edge of a piece of laundry to be held against the apertured belt. Transverse movement of the belt allows centering of the piece of laundry with respect to the conveyor centerline. After centering, the support is moved to the second position, vacuum pressure is released and the edge of the laundry piece is allowed to fall onto the conveyor in centered relation thereto.
