  • Patent number: 4953687
    Abstract: An apparatus for transferring groups of pantyhose from loading stations to an unloading station with intermediate accumulating stations inbetween. An endless conveyor belt advances the pantyhose groups from either of the unloading stations to the next empty intermediate accumulating station, from one intermediate accumulating station to the next, and from an adjacent intermediate accumulating station to the unloading station. The belt operates in either direction depending on location of the station from which the pantyhose groups are to be advanced with respect to the unloading station. The conveyor belt is formed of a plurality of spaced elements and the platform is formed of spaced strips provided for extension through the spaces in the belt to support and retain pantyhose groups at a station while the belt advances pantyhose groups between other stations. The platform is retractable through the belt to place the pantyhose group on the belt for advancing from the station to the next station.
