Abstract:
A method of packaging a cylindrical article having a packaging sheet wrapped therearound, the cylindrical article having a hollow region therein, comprising the steps of:(a) moving a distal end of a presser disposed in opposition to the cylindrical article and having a core tube mounted axially therein, toward the cylindrical article to a position wherein said distal end of said presser is accommodated within an end of the packaging sheet;(b) projecting a distal end portion of said core tube from said distal end of said presser into the cylindrical article;(c) holding, using a plurality of first packaging sheet holders disposed concentrically around said presser, said end of the packaging sheet against the distal end of said presser while the distal end of said presser is accommodated within the end of the packaging sheet;(d) rotating said cylindrical article such that the end of the packaging sheet is coiled and gathered onto said distal end portion of said core tube;(e) holding, using a plurality of second packaging sheet holders disposed concentrically around said presser and disposed axially inwardly closer to the cylindrical article than said first packaging sheet holders, said coiled packaging sheet against the distal end portion of said core tube on which said packaging sheet is coiled; and(f) moving said presser toward the rotating cylindrical article when the end of the packaging sheet is fully gathered on said core tube, to press the gathered end of the packaging sheet into the hollow region in the cylindrical article;wherein said core tube is withdrawn by moving said core tube axially away from the hollow region before the gathered end of the packaging sheet is fully pressed by said presser into said hollow region.
