Meeting your requirements from Start to Finish
SEM SP specializes in producing copier and printer cleaning brushes from end-to-end. We tailor the brush design for the specific cleaning function it must perform. The fabrics used in these rollers are generally developed for their individual applications and are typically specific to a given printer or copier model. These spiral wound soft pile conductive or non conductive brushes are typically used to clean photoreceptor drums and belts in toner-based printers and copiers. The result is a brush that cleans toner from hard, soft or flexible substrates.
The basis of SEM SP’s capabilities is our experience with textiles, the various materials and processes that can be used to produce fabrics. If a material can be spun into a filament or a thread, SEM SP can weave it into a fabric. It is possible to blend two or more fibers, as well as blend monofilament and multi-filament yarns to achieve desired performance. Our engineers specify fiber length, pile density and pile height to satisfy performance that is maintained at the manufacturing stage by careful manipulation of tension, uniformity of yarn speed and synchronized weaving motions. The result is total process control and an unrivaled level of pile fabric uniformity and consistency. SEM SP can blend and enhance fabrics and yarns in a variety of ways to meet application requirements. Typically, spiral wound brushes are produced consisting of fabric on cores of either cardboard, phenolic, or metal materials. All brushes are individually packaged in specially design cartons that protect the pile fabric of the brush from being contaminated or crushed during shipment.
- Cleaning copier toner from photoreceptive surfaces
- Transport belt and paper feed roller cleaners
- Dust removal
– Large diameter rollers (typically 70mm) with a low pile density, used at high impact speeds
– Small diameter rollers (typically 15 to 30 mm) with highly conductive filaments used at low rpm
– Very dense, small diameter rollers that act as toner disturber components, facilitating blade efficiency
– Abrasive brushes for more difficult cleaning tasks
- Pile Fiber Materials: Nylon, Polypropylene, Polyester, Acrylics, Modacrylics, Teflon* fibers, Teflon* fiber blends, Kevlar* aramid fiber and conductive fibers.
- Pile Fiber Length: .Typical range 075 to .750 inches (.2 to 1.9 cm)
- Pile Fiber Density: According to yarn and design criteria
- Plain or phenolic impregnated paper wound
- Plated or unplated steel
- Other metallic in tubular or solid form.
