<strong>TRANSDEV</strong> SPECIAL BELTS<br />

Other Special Belts<br />

TransDev Sausage Belts<br />

Sausage belts<br />

Synchronous, FDA approved material, moulded belt backings<br />

for sausage machines. With a moulded backing, having no<br />

overlap joint, belts can run in either direction, with no risk<br />

of delamination.<br />

‘The major cause of premature failure is unskilled staff<br />

running belts in the wrong direction after cleaning.<br />

Moulded backings stop this problem’<br />

Properties<br />

•<br />

Moulded backing, no joint to delaminate<br />

No adhesive layer to be attacked and degraded by cleaning<br />

Antistatic Belts Sprayed<br />

Dielectric materials, such as belt carcass materials, are by definition poor conductors of electricity. When such materials<br />

are separated after contact with either a conducting material or another insulating material, a static electric charge can be<br />

produced by the capacitance effect, which can lead to sparking or crackling.<br />

When these electric particles discharge they can cause the following problems:<br />

Destruction of sensitive electronic equipment<br />

Risk of ignition or explosion of flammable materials<br />

• Radio frequency interference (RFI)<br />

• Risk of shock due to the high voltages generated<br />

The British Standards BS2050 (1978) and DIN 22104 are the<br />

recognized specifications which cover the test procedures and<br />

accepted levels for rubber and Polyurethane timing belts relating<br />

to antistatic properties.<br />

TransDev has developed a post manufacturing electrically<br />

conductive black coating which complies with the above<br />

specifications and is available on all Polychloroprene type rubber<br />

timing belts and currently on 3 different Polyurethane belt<br />

substrates (All BRECO®/BRECOFLEX® & SYNCHROFLEX® belts).<br />

The antistatic timing belt is, therefore, a specific and new<br />

solution for all those who operate in hazardous industrial fields,<br />

where static build-up would present potentially disastrous<br />

circumstances (e.g. chemical, mining, oil and electronics).<br />

Elimination of RFI also makes for easier FCC and CE certification.<br />

It is obvious that during the working life of the drive that the<br />

eventual reduction of conductivity means that the testing<br />

of the belt’s resistance in a planned maintenance schedule<br />

is important. TransDev is also able to supply you with<br />

a belt surface conductivity tester.<br />

Additional Information<br />

• •<br />

The maximum surface resistance for BS2050 is 5x106<br />

x l/(8*b) Ohms and for DIN EN is 3 x 109 Ohms<br />

Certification is available for all belt types<br />

Other substrates may be suitable but please<br />
