  • Patent number: 4795031
    Abstract: A method for packaging a playing ball so as to provide a partially exposed surface of the ball which comprises the steps of imprinting selected indicia on a heat shrinkable plastic film loop, placing the loop about the ball in frictional contact with a portion of the surface of the ball, applying heat to the loop and the ball to shrink said loop so as to wrap a circumferential section of the ball, and removing the heat and permitting the loop to cool about the ball in its shrunken state. If the ball is partially deflated, the loop is placed about the ball and the ball is inflated until frictional contact between the ball and loop occurs with subsequent heat application.
