  • Apparatus for heat sealing plastic strapping
    Patent number: 5858164
    Abstract: An apparatus for heat sealing two pieces of plastic strapping together. The apparatus includes a heating element, upper and lower pressure elements, a rotation actuation member and a sealing actuation assembly. The heating element is movable between an engaged heating position--which orients the heat element between the pieces of plastic strapping--and a retracted position. The lower pressure element exerts pressure upon at least the bottom piece of plastic strapping during the heating of same by the heating element, and, in cooperation with the upper pressure element, upon both pieces of plastic strapping again during direct attachment of the melted portions of the plastic strapping after the heating element is relocated to its retracted position.
