Adjustable spindle assembly for rollfeed media in an inkjet printer/plotter

摘要

A spindle assembly for rollfeed media in a printer/plotter includes a spindle having differently sized hubs which are removably mounted on the spindle. One end of the spindle is used for axial referencing and includes an end cap having an axial latch and a rotational stop for manually actuated engagement/disengagement with hubs of different sizes, shapes and configurations. Each pair of matching hubs have outwardly extending arms for gripping a roll of media in a predetermined radial and axial location on the spindle. In a preferred embodiment, a small diameter spindle includes hubs capable of gripping opposite ends of either one inch diameter or two inch diameter rollfeed media cores. In addition, a hub design incorporates a plurality of cantilever arm members which require relatively low insertion force in order to adequately install the hubs into the rollfeed media cores.
