Abstract
Methods of sealing boxes by applying multiple lengths of box sealing tape on box flaps are described. The box may be of the type where the outermost pair of flaps are shortened such that they do not meet each other when the flaps are folded toward each other and for boxes where the outermost pair of flaps do meet each other. A tape source is provided that includes a cylindrical core assembly that has an outer surface about which plural tape lengths are circumferentially wound. The cylindrical core assembly may either comprise a single core or may comprise multiple cores that are attached to each other in a manner so that the multiple cores function in use as a single core. The methods of sealing boxes in accordance with this invention are carried out with box sealing tape used on a box sealing machine.
