A hand-held device for dispensing plastic film for wrapping stacked items including a hand-actuated braking mechanism to permit the holder to stretch the film as he winds it around a stack. The braking mechanism is actuated by rotation of one of the handles so that the stability of the roll is not affected during tensioning and wrapping.

A portable device for dispensing wrapping film from a roll comprising: (a) a roll-carrying bar; (b) a pair of roll plugs rotatably disposed on said bar, each plug comprising: (1) a first inner roll end insertion portion adapted to fit into the end of the roll to concentrically engage the inside surf

A portable device for dispensing wrapping film from a roll comprising: (a) a roll-carrying bar; (b) a pair of roll plugs rotatably disposed on said bar, each plug comprising: (1) a first inner roll end insertion portion adapted to fit into the end of the roll to concentrically engage the inside surface thereof; (2) a second roll end abutting portion attached thereto of greater diameter than the inside diameter of the roll, adapted to abut the end of the roll; and, (3) a flat outer surface formed on the outboard surface of said plug perpendicular to the axis of said roll-carrying bar; (c) a pair of pins extending from said second roll end abutting portion toward the roll for penetration into the end of the cardboard roll to hold the roll in mating engagement with said plugs; (d) a sleeve slideably received on one end of said roll-carrying bar and held thereon with a nut threadably received on said bar end; (e) a first arm extending from said sleeve; (f) a cross handle extending from the free end of said first arm; (g) a second arm pivotally anchored to the other end of said roll-carrying bar and extending therefrom; (h) a cross handle extending from the free end of said second arm; (i) a brake cam formed on said second arm adapted to contact said flat outer surface of said adjacent plug; and, (j) at least one friction-producing, compressible washer slidably received on said bar between said second arm mounting sleeve and said flat outer plug surface of said adjacent roll plug to provide increased rotational friction between the roll and said cross handles when squeezed between said sleeve and said outer plug surface upon said brake cam being rotated into contact with said flat outer surface of said adjacent roll plug by twisting said cross handle attached thereto.
