This is one of GIRON SA's leading products. We invented this type of screen and patented it in 1951.

These screens have the same wear-resistant qualities as the ONDAP GOMME. These screens are interesting when the feed is made of big size materials and when small separation is required, or also when the feed rate is very important.

This screen produces excellent results when confronted with heavy clogging. The absence of any contact between the warp wires prevents the agglomeration of fines.


We manufacture screens with mesh of between 1 and 60mm and with wire of between 0.7 and 7 mm.

This screen, copied by many others but never rivalled, eliminates plugging (elements wedge in the mesh) and clogging (very fine particules adhering to a screening surface). All the wires are independent of each other and lonely vibrate. This prevents very fine products from clustering or clogging together and thus blocking the mesh. Moreover, in case of high levels of abrasion caused by fine products under water screening, the ONDAP GOMME screen has a higher lifetime than a classical woven mesh. A precise and stable square mesh of evenly spaced wires is ensured by the presence of steel wefts in all the rubber bands on the anti-clogging screen. The use of rubber rather than polyurethane wefts enhances the flexibility of the screens and thus increases the efficiency of vibration.

Alternating crimped and straight wires facilitates de-clogging and de-plugging whilst maintaining high rigidity and wear-resistance levels. Should temperature levels of above 90C be required - which is, notably, the case with cements process - MIXTE ACIER steel screens are recommended. The rubber bands are replaced by steel wefts and by special sheet metal providing satisfactory mechanical strenght to wear.

In relation with the form of the mesh and the possibility that long elements may pass through it, the conditions under which the ZIGZAG GOMME screen is used must be determined with care. All this, to define the form of the crimp the best suited to the screening problems involved.
