Spiral Wound Brushes

Meeting your requirements from Start to Finish

Schlegel 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 generally 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.


Characteristics

The basis of Schlegel'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, Schlegel 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 are 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 n unrivaled level of pile fabric uniformity and consistency.

Schlegel can blend and enhance fabrics and yarns in a variety of ways in order to meet application requirements. Spiral wind manufacturing processes consist of fabric on cores of either cardboard or phenolic materials, our newest process includes small metallic cores. The adhesive systems include liquid adhesives or pressure sensitive hot melts. Once the cores have been wound, the brushes are staged for the appropriate finishing operations: endcapping, steaming, combing, shearing, and inspection.

Finally, all brushes are individually packaged in specially design cartons that protect the pile fabric of the brush from being contaminated or crushed during shipment. Schlegel can also construct strip brushes by attaching pile fabric to roll-formed metal.

Applications:

  • 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

Specifications:

  • Pile Fiber Materials: Nylon, Polypropylene, Polyester, Acrylics, Modacrylics, Teflon* fibers, Teflon* fiber blends, Kevlar* aramid fiber
  • Pile Fiber Length: .075 to .750 inches (.2 to 1.9 cm)
  • Pile Fiber Density: According to yarn and design criteria
  • Core Materials:
  • Aluminum
  • Plain or phenolic impregnated paper wound
  • Plated or unplated steel
  • Other metallic in tubular or solid form.

Acoustic Seals

Noise, anywhere it occurs it can distract, annoy or even lead to dangerous conditions. SCHLEGEL acoustic seals will make equipment quieter and help insure compliance with noise emission standards mandated by OSHA, VDE and others. Acoustical seals are made form a durable, flexible cladding and soft resilient foam in several profiles that create excellent barriers to noise.


Characteristics

Resiliency: Schlegel acoustical seals will retain their shape due to their resistance to compressions set.

Flexibility: Open-cell foam yields low compression forces which allow the seals to compensate for irregular mating surfaces. Because acoustical seals are easily compressed, covers and panels are not distorted when shut.

Durability: Tough, yet, flexible outer cladding is UV stabilized, resists abrasion and won’t stiffen, shrink or detach from the foam core. Low coefficient of friction eases operation in sliding applications.

Stability: Outer film cladding on acoustical seals resists elongation and gives the seal tensil strength far greater than common unclad foam strips.


Specifications

Material Composition: Open-cell polyether polyurethane foam bonded to an outer covering of polyethylene or vinyl film. Film colors include black, white, bronze, beige and grey. Please contact Schlegel for availability of profile/color combinations. Profiles: Customer profiles are Schlegel’s specialty. Send your drawing and requirements for evaluation by our design team.

Finishing: Processes include cut-to-length, die-cut, mitered or formed to finished shape. Pressure sensitive adhesive can be applied to surface mount applications. Profiles with pressure sensitive tape should be applied to clean, dry surfaces at temperatures above 32°F (0°F). Recommended storage of taped products at 72°F (22.2°C), 50% RH.


Test Information

With SCHLEGEL acoustic seals, attenuation of 50dB+ is possible depending on the frequency, amount of compression and profile selected. The chart below show the acoustical attenuation performance of one of our most used profiles.

Results shown are typical of a urethane foam formulation. Some values may differ depending on profile size, shape, and foam formulation.
