Machine in cigarette factory for consolidation of axially orientated groups of cigarette filter plugs has roll drum with corrugated surface, trapping plugs against rough stationary surface

摘要

The consolidation roller (29) may be a tube with a surface (62) roughened to form a series of axial ridges and grooves. The strands of filter material are squeezed between this rough surface and a roughened stationary surface (54) on a hinged flap. The flap may be spring-loaded.
