Abstract
A free end portion of sheet wrapping material is grasped and pulled from a dispenser transversely past and spaced from a cutting element mounted on a housing. The cutting element is displaced in response to the movement of the withdrawn material by generating a displacement force, latching the cutting element against displacement in a normally guarded position in which the cutting element is inoperative for cutting, and thereupon unleashing the displacement force in response to a further movement of the material to drivingly displace the cutting element from the guarded position to a cutting position in which the cutting element is in a position to sequentially pierce and cut the sheet material that is subsequently moved toward the same. Methods of dispensing the sheet material and of wrapping items also are disclosed.
