  • Patent number: 5740552
    Abstract: A roll of disposable aprons is formed from an elongated strip of plastic film having a portion along each side which is longitudinally folded over the remaining portion of the strip. The strip contains a plurality of latitudinal perforations at spaced intervals to enable the strip to be readily separated into discrete sheets. Each sheet has a cut-out portion near the top and centered latitudinally in the sheet. Each sheet also has a cut-away portion on each side of the hole portion which begins on the outside edge at the top of the strip, then runs inwardly and downwardly, and then ends on the outside edge of the strip. The cut-out portion defines a neck opening and the two strips of the folded-over portions adjacent and inward of the cut-away portions define two waist tie straps.
