Abstract
A spindle assembly for supporting a roll of paper product is disclosed with features that make the spindle versatile and useable for supporting paper product rolls in a plurality of styles of dispensers. The spindle assembly also includes features that assist in maintaining the supported paper rolls in a desired orientation, such as horizontally in a vertically oriented dispenser. This resists skewing of the rolls in the dispenser and facilitates the separation of the rolls as paper is used from a lower roll in a dispenser. Also, brake members are provided to engage the core of a supported roll of paper to slow down the rotation of the roll of paper when pulled upon by a user.
