The apparatus includes a supply assembly, a conversion mechanism, a cutting assembly and a cutting assembly interlock device. The supply assembly supports the paper which is to be converted. The conversion assembly crumples single ply paper into cushioning dunnage and the cutting assembly cuts the newly formed dunnage into desired lengths, where the dunnage is allowed to fall into a container to cushion an item within the container. The cutting assembly interlock device permits activation of the cutting assembly only when the cutting assembly has fully moved into the proper, cutting position. ## Claims ### Claim 1 An apparatus for rotatably supporting a paper roll core on a mount, the paper roll core having a first and second end, a mandrel lock hole located proximate to at least one end, a mandrel positioning hole located at the at least one end and a longitudinal axis extending therethrough, and paper being wound around the paper roll core, the apparatus comprising: a paper tube plug having a core end and a mounting end, the core end for being positioned within the first end of the paper roll core, the paper tube plug including an outwardly biased mandrel lock being located between the core end and the mounting end of the paper tube plug and a stop plate positioned between the outwardly biased mandrel lock and the mounting end, the paper tube plug further includes a mandrel positioning stop located between the outwardly biased mandrel lock and the stop plate, the outwardly biased mandrel lock being complementarily positioned on the paper tube plug so that it is aligned with and extends into the mandrel lock hole when the plug is positioned within the end of the paper roll core to rotatable lock the plug to the paper roll core, the mandrel positioning stop being selectively positioned on the paper tube plug so that when the mandrel positioning stop is within the mandrel positioning hole, the mandrel lock is aligned with and positioned within the mandrel lock hole. ### Claim 2 (depends on 1) The apparatus according to claim 1, further comprising a mandrel handle attached to the mounting end of the paper tube plug, the mandrel handle being co-axial with the longitudinal axis and extending away from the paper roll core along the longitudinal axis. ### Claim 3 (depends on 1) The apparatus according to claim 1, wherein the outwardly biased mandrel lock is spring-loaded. ### Claim 4 (depends on 1) The apparatus according to claim 1, further comprising a second paper tube plug for being positioned within the second end of the paper tube core. ### Claim 5 A combination paper roll core and paper tube plug, the combination comprising: a paper roll core including a first and second end, a mandrel lock hole located proximate to the first end, a mandrel positioning hole located at the first end, and paper being wound around the paper roll core; and a paper tube plug including a core end and a mounting end, the core end being positioned within the first end of the paper roll core, the paper tube plug including an outwardly biased mandrel lock located between the core end and the mounting end of the paper tube plug, the outwardly biased mandrel lock being complementarily positioned on the paper tube plug so that it is aligned with and positioned within the mandrel lock hole, the mandrel lock rotatable locking the plug to the paper roll core, a mandrel positioning lock being complementarily positioned on the paper tube plug so that it is aligned with and positioned within the mandrel positioning hole.
