The eye link is created by a succession of eye links. Eye links are pieces of wire with a bended eye at both ends. These eyes are connected to one another by means of cross rods consisting of welding heads at the sides. In order to strengthen the belt, rows of metal bar links are woven into it. The eyes could, when desired, be kept on distance. This is realized by means of metal springs whereby a more open belt is obtained.
- – Pitch: 25,4 / 30 / 50 / 50,8 / 75 mm
- – Mesh width: equal to the wire thickness of eyes by means of springs
- – Eye link wire: ø 1,5 / 2,0 / 2,5 / 3,0 mm
- – Cross rod wire: ø 4,0 / 5,0 / 7,0 / 8,0 mm
- – Materials: 1.0304 (non processed) / 1.4301 (SS304) / 1.4401 (SS316)
- – Temperature range: cryogenic up to approximately 250 °C
- – Range of the width of the belt: OGB up to 2000 mm (take a look at clearance at features)
- – Range of the width of the belt: OGB-S up to 6500 mm
- – Heightened side guards are a possibility
- – Possibility to attach cross flights
- – Possibility to confirm a plaatvulling
- – Possibility to install special product carriers
- – Lateral chains are a possibility (take a look at Type 1000: KE)
- The OGB belts are characterised by:
- – Drive on the basis of sprocketss/drums; no chance on belt slip
- – Very straight belt run due to the positioned drive element en the possible application of special ‘’doorgezette’’ bar links.
- – Very heavy loads are possible due to the variable construction of the rows of bar links
- – Support: strips in length direction under the rows of bar links
- – The belt is really dense (little pass range) in the case of an OGB version
- – An OGB belt will, just after usage, exhibit “roof shaped”. This is caused since the belt has been welded relatively tight. If this doesn’t happen protruding cross rods will occur, or an aperture (slit) in the belt starts to exist since the present clearance accumulates in the belt
- – The belts isn’t suitable for small products since the present clearance in the belt will eventually accumulate, this could cause an aperture in the belt.
- – Simple to clean since no residue can pile up in the spirals to the application of special bar links with slits. In case of very vulnerable products, for example with a fragile curst of the product, the chance on product damage can be minimalized by means of special bar link from ‘full material’’.
- – In comparison with other belt types, a long life span can be realized. It is possible to extend it by using eccentric (extra high) bar links
- – Tools are inflexible; not every combination of longitunal pitch/lateral pitch/ spiral wire/cross rod wire is possible.
OGB(-S) belts are the precursors of OGB-L belts. They are therefore common with an extensive application field. Especially when we take stock of the replacing belts. OGB(-S) belts are used relatively little in new installations. Sometimes the OGB belts are preferred when compared to the to OGB-L belts. This is especially the case in installations whereby very low temperatures are realized. A reason for that is that the eyes, near the weld connection with the localisation wire, break off. Tribelt however has a controlled welding process, whereby the input of excessive heat is being avoided. As a result, the change of structure among the materials nearby the weld is minimal. This means that the eyes break off less quickly.
