Abstract:
1. In combination, a roll of tape, and a tape roll core assembly for mounting the roll of tape thereon such that regardless of the internal diameter of a particular roll of tape that may be selected from a plurality of rolls of tape, said tape roll core assembly can tightly engage the particular roll of tape, comprising: a roll of tape disposed upon a tape roll core having an internal peripheral surface which has a predetermined internal diametrical extent; a tape roll cartridge core member defined around an axis for supporting said roll of tape thereon when said roll of tape is mounted upon said tape roll cartridge core member; a first set of threads defined upon a first external peripheral surface portion of said tape roll cartridge core member for defining a first part of a threaded connection; a second set of threads defined upon an internal peripheral surface portion of a nut member for threaded engagement with said first set of threads defined upon said first external peripheral surface portion of said tape roll cartridge core member so as to define a second part of said threaded connection; an annular collar portion defined around said axis of said tape roll cartridge core member upon a second external peripheral surface portion of said tape roll cartridge core member, wherein said second external peripheral surface portion of said tape roll cartridge core member, upon which said annular collar portion is defined, is directly connected to said first external peripheral surface portion of said tape roll cartridge core member upon which said first set of threads is defined; and an annular ring member, separate from said annular collar portion of said tape roll cartridge core member and said nut member, and interposed between said annular collar portion of said tape roll cartridge core member and said nut member, so as to be movable along said annular collar portion of said tape roll cartridge core member in an axial direction, and having diametrically adjustable structure defined thereon for progressively engaging said annular collar portion of said tape roll cartridge core member as said annular ring member is moved axially along said annular collar portion of said tape roll cartridge core member in response to said second set of threads, defined upon said nut member, being progressively threadedly engaged with said first set of threads, defined upon said tape roll cartridge core member, such that said diametrically adjustable structure of said annular ring member progressively increases the external diametrical extent of said annular ring member and thereby tightly engages said internal peripheral surface of said tape roll core of said roll of tape mounted upon said tape roll cartridge core member such that regardless of the particular internal diametrical extent of a particular tape roll core of a particular roll of tape, selected from a plurality of rolls of tape having different tape roll cores having different internal diametrical extents, said particular roll of tape may be fixedly secured upon said tape roll cartridge core member.
