  • Patent number: 5310102
    Abstract: A vegetable sleever is disclosed suitable for field-wrapping of vegetables such as leaf lettuce at the time of harvesting in order to prevent shipping damage. The sleever contains a steel frame assembly having three hangars for holding plastic sleeves. For each wrapping, a sleeve is individually opened, the product inserted and the sleeve removed from the sleever assembly and placed in a packing container. The sleeves are protected from wind and dirt by a front shroud covering the sides and lower front, and protective flaps on top. The frame assembly may be either used with a harness and attached to the lower leg while working in the field or mounted to a fixed support on a harvester or in a vegetable preparation area.
