75 Reinforcement of Belt Systems By including reinforcement links it is possible to: reduce elongation caused by temperature changes. reduce the permanent elongation which occurs in all belts.

76 Reinforcement and itch Control of Belt Systems On long conveyors used in applications with high temperature variations changes in the length of the plastic modular belt calls for large takeup systems. Reinforced uni OB unichains can offer a solution that reduces the change in the belt length to only 10% of traditional modular plastic belts.

All users should read our "Warnings" and "Design Safety Guidelines" before using our products. 77

78 Warnings Fire unichains plastic products are, unless clearly specified, made from materials which support open flame. roducts made from OM material (D, I, F and SF), when so exposed, will emit toxic fumes. unichains plastic products should therefore not be exposed to extreme temperatures or open flame. Special care should be taken when undertaking repair work particularly when welding at a conveyor if the conveyor is fitted with plastic chains or belts. ersonal rotection Always use safety glasses when mounting or repairing chains and belts and while securing or removing pins. Use only suitable tools in good condition. he weight of some products calls for the use of safety shoes. When installing/removing or repairing chains or belts on a conveyor, the motor must be turned off. Design Safety Guidelines Most plastic products will lose their mechanical properties if exposed to the sun or ultra violet beams, which can lead to chain or belt breakage. his can also happen if the products are exposed to strong chemicals. Generally, this is a problem with ph values lower than 4.5 or higher than 9. Always make sure that there is enough space in the conveyor frame to allow chains and belts to retract or expand when exposed to temperature variations. Never exceed the maximum or minimum temperatures given by unichains. Note: he different materials have different temperature limits. Care should be taken with high chain/belt speeds with which friction can lead to heating and subsequently melting of chain/belt as well as wearstrips. Do not exceed speeds recoended by unichains. Use only original unichains sprockets with unichains belts and chains. When constructing conveyors it is important to always include sufficient cover around the moving parts to prevent fingers and clothing from being caught in the machinery. unichains can also supply safety chains and side flexing belts which leave minimal gaps when turning through curves making them incredibly safe. 78
