    • PURPOSE:To automate cylindrical shaped article packaging work and save labor in the said work, by inserting a mandrel in the inner hole of a cylindrical shaped article, then releasing a paper end holding equipment, and expanding a multiple number of segments on the mandrel one by one. CONSTITUTION:A mandrel is set at the center of an inner hole 1a of a coil to be packaged 1; under a condition where a packaging paper 10 is wound around the mandrel, and the paper end is held by a holding equipment 36, the mandrel is inserted in the bore of the coil to be packaged; by a segment expanding screw 32 and the operation mechanism 31, the outer diameter of the mandrel is expanded to a required dimension when necessary. The paper end holding equipment 36 is made to retreat; a short stroke cylinder for individual segment 34-1-8 is operated as 33-1-8; the packaging paper 10 is spread on the internal hole 1a of the coil to be packaged 1. The overlapped portion of the packaging paper 10 will locate at a same position with a taping equipment 40; under that condition, the taping equipment is made to operate to conduct a taping in the axial direction of the coil to be packaged 1 along the overlapped portion of the internal packaging paper; thus the installation of the internal packaging paper is completed.
