ABSTRACT:
An annular end member of plastic material for insertion into an end portion of a hollow cylindrical core member of a tubular core assembly for a roll of paper or other sheet material has an outer annular surface securable to an inner annular surface of the core member and an inner annular surface shaped to receive a roll supporting chuck. A radially-projecting lug adjacent an end of the end member is engageable in a lug-receiving notch in the core member, and a plurality of circumferentially-spaced axially-extending channels are provided in the inner annular surface of the end member to receive radially outwardly movable portions of a chuck. The channels have side walls engageable by the radially moveable chuck portions to enable rotational movement of the chuck to be transmitted to the end member. The end member also has a notch for receiving a projection of a roll supporting chuck, the notch extending inwardly from the end of the end member immediately radially inwardly of the lug. The end member can be constructed so as to be a universal fit on various different types of chuck.
