ABSTRACT:
A paper roll holder having a cylindrical spring freely floating about one end of a spindle to frictionally engage the inner cord of a paper roll as the roll is pushed onto the spindle, retaining the roll securely in position. A thin cylindrical tube interposed between the spring and the spindle prevents interference of the spring with the spindle during insertion and rotation of the paper roll.
