Abstract:
Apparatus to apply a spiral wrap to a bundle of conduit ducts, said apparatus including: a frame rotatably supporting a rotator driven by a drive for rotation about a central axis extending perpendicular to the plane of rotation by said rotator, said rotator including two rings joined to form a unitary rotator with each ring having an U-shaped cross section defined by inner and outer concentric ring sections joined by a radial flange section, said ring sections forming bearing supports and wherein said frame includes two frame sections joined to form a unitary frame with each frame section having a L-shaped cross section defined by carrier plate section joined with an annular outer flange section; between said inner ring section and said outer flange section for rotatably support of said rotator by said frame, said rotator having an internal passageway of a size sufficient for the internal passage of an elongated bundle of conduit ducts arranged in a preestablished geometrical array along said axis which is generally parallel with the extended length of the elongated bundle of conduit ducts; at least one binder support arbor secured to said rotator for rotatably supporting a supply of an elongated binder, said binder support arbor being driven by said rotator in an orbit about said axis; a binder guide supported by said arbor to extend generally radially toward a geometrical array of conduit ducts as advanced through the internal passageway of said rotator for directing the binder from said binder support arbor to wrap in a spiral fashion about the outer periphery of the bundle of conduit ducts.
