  • Carton hold-down apparatus
    Patent number: 4173921
    Abstract: Apparatus for holding the flaps of a carton to allow the glue to set and seal the flaps in the closed position. After glue has been applied and the flaps are folded to the closed position, there is a short time period that the flaps must be maintained closed by an external force. Because of the uneven contour of the flaps, the subject invention is provided to apply this force in a firm yet yieldable manner to allow for the uneven carton contours while not exerting unneeded force on the carton contents as it moves through the apparatus.
