Custom Spiral Brushes

Spiral brushes arrange strip, tuft, or wound filament in a helix around a shaft or core. Unlike a straight-row roller, the angled path introduces progressive contact along the working width and can direct loosened material toward one side or away from a process zone.

Helix direction, pitch, number of starts, outside diameter, working length, trim, density, and shaft interface determine coverage and discharge. The spiral must be matched to rotation direction and material flow; the wrong hand or pitch can move residue toward the wrong side or leave gaps in contact.

Provide the shaft drawing, working length and diameter, helix hand and pitch, rotation direction, material-flow direction, residue, line speed or customer-supplied machine speed, installed contact, balance requirement, and replaceable-section preference.
