  • Patent number: 4954033
    Abstract: A conveyor system for transporting a succession of thin flexible sheets such as plastic bags from a bag forming device to a bag stacking device. The conveyor system includes a first conveyor having vacuum holes for holding the bags in place, with portions of the bags extending beyond the conveyor's edges. The system further includes bag support apparatus such as a pair of auxiliary conveyors located alongside the first conveyor and supporting the overhanginig portions of the bags. The auxiliary conveyors terminate short of the end of the first conveyor, such that for a predetermined distance the overhanging portions of the bags are unsupported, thus permitting a bag stacking device to lift the bags and deposit them onto a stack.

  • Patent number: 4091925
    Abstract: A preferably plastic film flower sleeve has side edge heat sealed front and back panels tapering inwardly in downward extension providing upper and lower open ends. Each panel has a centralized nonperforated area which increases progressively in transverse width during its downward progression bordered by transversely opposite perforated groups decreasing correspondingly in transverse width during downward progression, the perforated groups also being defined by nonperforated upper and lower end portions. A flower sleeve may be rearwardly rack suspended and forwardly hand suspended during insertion of a flower bunch downwardly therein, the flower bunch stems being maintained forwardly aligned with the progressively increasing nonperforated areas to avoid snagging and the stems ultimately projecting from the sleeve lower end while the increased size flowers of the bunch automatically transversely expand the sleeve perforated groups.
