ABSTRACT:
A plug is provided for use in packaging roll goods rolled about a hollow, substantially cylindrical core. The plug is adapted for coupling with the core to assist in fixing the position of the roll goods. The plug comprises a cylindrical portion designed to fit within the core with a small clearance so that the axes of the core and the plug are substantially coincident with each other. A flange extends from the cylindrical portion and is engageable with an axial end of the roll goods to limit relative axial movement of the plug and the roll goods with respect to each other. A nose extends axially from the substantially cylindrical portion in spaced-apart relation to the flange. The nose is substantially conical, has a base diameter substantially equal to the diameter of the cylindrical portion, and tapers to a vertex spaced apart from the cylindrical portion. This facilitates blind coupling of the plug and the core even if the plug and the roll goods when making initial contact with each other are laterally offset from each other by a distance up to a half of the diameter of the core.
