ABSTRACT:
A brushroll having a spindle and a pair of end assemblies each including a thread guard, a shouldered stub shaft, a bearing and an end cap. The thread guards each include a pair of radially spaced annular wall portions which define channels opening outward from the spindle. The end caps have peripheral walls which extend into the channels defined by the thread guards to prevent threads loosened by the brushroll from fouling the brushroll bearings. Spools formed in the end caps cvapture threads flowing outwardly along the brushroll to prevent the threads from working their way back to the bearing. In a preferred construction, the spindle carries tufts which are angled toward the ends of the spindle in order to encourage the flow of threads toward the ends of the spindle. The brushroll assembly is particularly suited for use with a wooden spindle since the thread guard and the stub shaft synergistically combine to retain the end assembly against the spindle even if the end spindle expands or contracts due to changes in ambient humidity.
