Industrial Fabrics: an extensive range of plush, velvet and brush ‘pile’ fabrics for multiple applications

Schlegel produces an extensive range of plush, velvet and brush ‘pile’ fabrics. All our fabrics are manufactured on purpose-designed narrow pile looms, giving our development engineers the greatest possible freedom in their selection of weaving patterns, densities, and fibre combinations.

The fabrics are manufactured in continuous lengths. Completing them with finishing operations such as back coating, slitting, cutting and co-extrusion enables us to provide ready-to-install components.

To clean printing heads, sensors in ink jet printers and ATM machines, Schlegel has developed special fabrics custom designed using all types of pile fibre materials such as Nylons, acrylics, modacrylics, PTFE, aramid fibres and or a blend of above. The fabrics do have a cleaning sealing function and also can increase the time an ink jet printer stays within register by a factor of 4.

The density and finishing depend on yarn selected, design and application. Products can be kiss cut, self stick, non self stick mounted on a holder etc.

Applications include:

nDust and environmental seals for office equipment, car interiors, car sunroofs and vacuum cleaner nozzles

nToner seals for printers and copiers

nTeflon pile seals for toner cartridges that also act as grease-free bearings

nLight seal velvet for microfilms, photographic equipment and photosensitive paper packaging

nHead cleaning pads for ink jet printers – ATM machines



nAttractive, durable and long lasting component to your entry mat system

nCustom pile colours are available for larger installations

nIdeally suited for the heavy duty contract usage

nPossible installations include: golf clubs, airports, hotels, public buildings, shopping centres, car showrooms, athletics clubs, stadiums and exhibition centres



Industrial Flooring: durable and long-lasting woven pile fabric carpet strips for entry mat systems

Schlegel woven pile fabric carpet strips are designed and manufactured to provide an attractive, durable and long-lasting component to your entry mat system. They feature nylon filament and polypropylene construction that will give years of service under the most demanding conditions.

Available in varying pile heights, widths and colours to compliment any architectural design, the closed construction ensures that all debris is captured by the mat surface for a convenient cleaning operation.

The Schlegel textile engineering group will work with your architect, design engineer or facilities engineers to design and fabricate just the right carpet strip for your needs. Because the fabrics are weaved in continuous length, we can accommodate long lengths where larger entry mats are desired.

Custom pile colours are available for larger installations where a signature color is desired. This benefit is especially attractive where large or multiple public spaces are to be protected such as shopping complexes or arenas and where a trademark colour is wanted.

Schlegel capabilities in both weaving and finishing guarantee you of close dimensional tolerances. This facilitates the insertion of the carpet strip into the extrusion, making Schlegel carpet strips cost effective in both the initial installation and in maintenance cost.

Cleaning Brushes: complete range of high performance brushes for printers and copiers

Schlegel manufactures cleaning rollers using a spiral winding process. The fabrics used in these rollers are specially developed for their individual applications and are generally specific to a given printer or copier model. Available to fit any type of shaft, these rollers are typically used to clean photoreceptor drums and belts in toner-based printers and copiers.

Extensive experience enables us to blend yarns with different properties and fine-tune fabric densities to develop brushes offering unique performance benefits. These fabrics boast an extremely uniform brush surface, unmatched by traditional brush manufacturing processes.

Static Dissipators: reliable, cost-effective solution to passively reduce static electricity build-up

Static electricity can be generated wherever two dissimilar materials come in contact. To complicate matters, the potential for static increases as transport speed increases. The impact of static on machine reliability and performance can be severe and in some cases, the electrical charge reaches such high levels that discharges can be painful for machine operators.

So, it’s easy to see why controlling static has become a bigger concern than ever. Static dissipators are reliable, cost-effective solution that passively (i.e. without power consumption) reduces static electricity to an acceptable level.

As paper, film or other materials pass through critical points of the machine’s path, each piece is lightly brushed by the conductant. The brush draws the charge from the object, dissipating it through the machine frame to ground.

Technical Details

Passive static dissipators have traditionally been manufactured using conductive carbon filaments or stainless steel yarns (typically 10 to 14 µm in diameter). A number of special conductive manmade yarns now offer cost-effective alternatives. Newer approaches use electrically-conductive plastic films or non-woven materials. Most anti-static devices feature an aluminium or stainless steel frame to enable simple mechanical assembly techniques. Grounding harness, studs and terminals can be pre-mounted.

Self-adhesive versions using electrically conductive, pressure-sensitive adhesives can be used when appropriate.

Fuser Roller Cleaning Components: high performance components that oil as well as clean

Most toner-based printer engines use hot rollers to fuse the latent toner image onto the paper. Schlegel offers a variety of high-performance cleaning components, which remove the toner residues that accumulate on these fuser rollers. Although some components solely have a mechanical cleaning function, most of them also dispense silicone oil.

Oil rollers

Schlegel has developed a range of different systems for applying silicone oil on fuser rollers to clean them. As the fuser area operates at temperature of 200°C or above, all the materials used have to be designed to withstand these extreme temperatures. Aramid yarn resists high temperatures. It is used to produce a brush fabric that is wrapped around a core containing high-viscosity silicone oils. A number of different oil storage media can be used, including felt, foam, paper, ceramic foams and hollow shafts. Constant and uniform dispensing of the oil together with a continuous cleaning action is essential to ensure these components enjoy a long service life.

nTypical diameters from 15 to 40 mm with a 2 to 3 mm fabric thickness (pile or felt)

nOil storage capacity: 5 to 50 g or higher

nOil storage media: aramid yarn converted into felt paper or non-woven, paper, open or closed-cell silicone foam, perforated metal tubes (with oil flow controlling barrier layers or film), ceramic foams

Oil cleaning webs

Your guarantee of constant cleaning and oiling. The type of non-woven material to choose depends on the type of cleaning desired, as well as the temperature range and oil dispensing required. Possible materials include nylon, polyester, aramid, Teflon and blends. Oil webs require a more expensive machine that includes a drive mechanism. But the superb cleaning and oiling they provide is more than justified in high-volume and colour printers.

nA wide range of non-woven blends

nThicknesses ranging from 10 to 70 µm

nWeights of 20 to 50 g/m2

nOil densities from 5 to 40 g/m2

nWeb lengths up to 100 m

Oil pads

Stationary high-temperature brushes or velvet strips impregnated with silicone oil are used as a cost-effective, low-performance alternative.

nAramid felts or fabrics with 5 to 10 g oil capacity

nPlastic or metal carriers

Corona Wires: produces the various charging and discharging cycles in photoreceptors, drums and belts

Corona wires are widely used in toner-based printer engines, being a highly reliable, cost-effective component for producing the various charging and discharging cycles in photoreceptors, drums and belts. Corona wires allow extremely uniform charging, even in the fastest high-resolution printers. Regular cleaning ensures corona wires offer a long service life. Modern office equipment designs enable precise control of the ozone generated by corona wires during operation.

Carefully selected tungsten alloys are used as the base material. The finished product is a pre-mounted corona wire with eyelets, springs, terminals or other connecting devices.

Uses and finishes

Corona wires are used in various stations as charge, pre-charge, clean transfer or separation coronas. They have tightly-controlled diameter tolerances and offer the highest tensile strength for any given diameter, enabling maximum pre-tensioning to avoid vibration at minimal diameters.

A range of different surface finishes are available to reduce contamination and the onset of corrosion on the wire surface:

nChemical cleaning: the tungsten wire has no additional surface finish; in this state the wire already has superior purity and smoothness

nOxidisation a controlled oxidation process deposits a thin even layer of tungsten oxide that tempers further oxidation in the printer engine processes

nGold or platinum plating: the tungsten wire is covered with a thin layer of precious metal to suit the specific print engine processes. This coating significantly increases the service life of the corona wire

The cleaning interval depends on the surface finish selected.
