These brushes start as straight strip brushes and are formed into a cylinder shape with the metal on the outside and the filaments pointing towards the center. The brush is then stretched open to the required pitch, sometimes referred to as lead.
Rotary coil brushes, also called cylinder brushes, are industrial cleaning, moving, or sorting brushes made for a variety of applications & industries. The brushes are made to be mounted to equipment, known as "loose coil" or can be adhered to a steel shaft for standalone use.
Industrial coil brushes are made by winding straight metal-backed channel strips on a mandrel, core or shaft to form rotary cylinder brushes. By varying the pitch between each coil, a wide rage of brush densities is possible. From very dense close-wound coil brushes, to progressively less dense more open wound coil brushes, depending on pitch.
This type of brush can be supplied as a complete assembly pre-mounted on a core with journals, wound directly on to a shaft, wound on a customer’s core or shaft, or as replacement coils for in-house installation. Typical applications include conveyor cleaning, panel dusting, glass washing, screen cleaning, material handling (as screws and augers), lint removal and fruit and vegetable washing. Carolina Brush is capable of designing and manufacturing any custom coil brush to meet our customers’ application.
