ABSTRACT:
A method of mounting narrower paper rolls for unwinding on a pair of stub chucks spaced for mounting and unwinding full width paper rolls and carried by arms of a pair of multiple reel stands includes providing a narrower paper roll wound on a tubular core assembly having a hollow cylindrical core member and an annular end member of metal or plastic within each opposite end portion of the core member. The end members are removed from the core member, and the core member is mounted at a desired longitudinal location on a full length shaft having opposite ends engageable with the stub chucks. Core member engaging devices are provided to enable the core member to be secured in the desired longitudinal location and to transmit rotational torque from the shaft to the core member. The full length shaft with the narrower paper roll thereon is then mounted on the stub chucks. A narrower paper roll can thus be mounted on multiple reel stands whose stub chucks are spaced for full width paper rolls without interrupting the unwinding operation of another paper roll mounted on the multiple reel stands.
