  • Patent number: 9598196
    Abstract: A manual wrapping apparatus includes: a wrap roll having a wrap wound around the outer surface thereof; a support rod, one end of which is provided with a first gripping area for the operator and the other end of which is coupled to the wrap roll; and a rotating grip portion which is rotatably coupled on one side on the outer surface of the support rod in order to provide a second gripping area for the operator. According to the present invention: the operator does not have to bend his or her body during the wrapping operation but can carry out the operation while maintaining a standing position so that there is no burden on the body of the operator despite the wrapping operation being performed over a long period of time; sufficient tension is added to the wrap being wrapped around a target object by using an additional stopper member so that the target object can be firmly fixed; and consumption of wrapping is reduced by the amount of the added tension so that logistics costs can be reduced.
