Spindle mechanism for protective packaging device

A web handling system, comprising:

• a spindle extending from a base portion, the spindle having:
• a spindle magnetic coupling portion including a plurality of magnets located on the base portion, wherein the spindle magnetic coupling portion includes a face on the base portion which is defined by a flange from which the spindle extends with the plurality of magnets located on the flange face, the plurality of magnets being permanent magnets, and
• a spindle mechanical coupler including a plurality of teeth forming coupling features along at least a portion the spindle proximal to the base portion, wherein the plurality of permanent magnets are located between the coupling features, that extend axially along the spindle from the face;
• and
• a roll core configured for receiving the spindle for mounting thereon, the roll core having:
• a roll core magnetic coupling portion that has a magnetic attraction to the spindle magnetic coupling portion,
• a roll core mechanical coupler that corresponds to and is engageable with the spindle mechanical coupler, wherein the magnetic attraction engages the roll core mechanical coupler and the spindle mechanical coupler axially along the spindle when the roll core is mounted on the spindle and the engagement between the spindle mechanical coupler and the roll core mechanical coupler is operable to transmit torque between the spindle and the roll core,
• a face operable to mate with the face of the spindle and the roll core face includes the roll core magnetic coupling portions.
