ABSTRACT:
A fiber opening device in a spinning unit of an open-end spinning machine wherein an opening roller is mounted within a housing with the housing being integrally formed from a drawing-in opening past a trash discharge opening to a fiber discharge opening and including integrally therewith a drawing-in trough and wall portions at the trash discharge opening. The housing is pivotally mounted to accommodate variations in the silver feed at the drawing-in roller. In an alternate form, the housing is stationary and the drawing-in roller is mounted for relative movement with respect thereto for the same purpose. The opening roller has a fiber opening surface to which the fibers are confined by side flanges on the opening roller and the trash discharge opening is of a width no greater than the width of the fiber opening surface. The opening roller inlcudes a drive shaft rotatably mounted in the housing so that the opening roller and housing are a unit for easy removal and replacement.
