Abstract
A helical brush section consisting of a split tubular support or drum. The drum is offset at the split when the brush strip is helically wound thereon with its ends corresponding to the shoulders at the ends of the offset drum. Then the section is subjected to axial pressure to restore the drum to cylindrical form which distorts and flattens the ends of the brush strip inwardly substantially flush with the drum ends. Multiples of this resulting section are adapted to be disposed on a mandrel with their adjacent edges and shoulders in axially-abutting relationship to form a continuous helical rotary brush with a minimum of bristle gaps at the flattened ends of the brush strips.
