Glossary of Terms

Aligned belt A Flat-Flex belt, which has had shapes, formed in each strand of the belt forming distinct rows in which a product can rest.
Belt supports (or carry ways) These may also may be referred to a wear strips and provide belt support on either product carrying side or return side or both. Depending on the material used, they can greatly influence the tension in the belt.
Blank   A support disk, similar to a sprocket with no teeth.
Bottom belt The product-carrying belt in a dual belt system, such as in a fryer. See “hold down” to describe top belt.
Catenary sag A belt hanging under its own weight between two (2) supports in the curved shape. This is our preferred gravity take up.
Cleat See flight
Compound belt A Flat-Flex belt made with one or more special strands with “flights” formed into a repeating pattern.
Gravity weight A weighted roll within the belt circuit, which is used to tension the belt at a constant, level.
Crown Flat-Flex belt, pre-stressed in a positive camber across the belt width, so when heat is applied, the belt will remain flat.
Decline conveyor A conveyor whose product exits at a lower elevation than the loading level. See also incline conveyors.
Discharge end Unloading end of the conveyor.
DLE Abbreviation for double loop edge. Reinforces the outside edge of the belt. Available with finer wires only. For single loop end, see SLE.
End roll The shaft at either end of a conveyor, but not a drive roll.
Enrober A machine used to coat products, most commonly referring to a chocolate enrober.
Enrober Belting Flat-Flex Type belting, as used on enrobers.
Flat-Aligned A Flat-Flex belt with a horizontal formation, in every space, to create a ‘Meat Roller’ belt.
Flex-Turn A conveyor, manufactured by Wire Belt, which transfers product gently and in line around corners.
Flight A shape pre-formed into the Flat-Flex strand that typically sticks out above the mesh. Usually used to help push a product up an incline. See compound belt.
Gear    See sprocket.
Hold down belt Also called “submerger belt” or “top belt”. Used in a dual belt system, this belt is used as means to hold product under a liquid such as in a fryer.
Idle roll A non-driven shaft in the conveyor circuit. Often referred to as the infeed roll or discharge end roll, end roll, or a support roll.
Idler rollers Steel or plastic pipes which spin freely on an end roll. Prevents damage to the “joints”. Commonly used as supports for belt return.
Incline conveyor See also decline conveyors. A conveyor with discharge higher than the infeed.
Infeed drive Belt is being driven or pushed from the loading end of the conveyor.
Infeed end The loading end of the conveyor.
Joint The bend in the wire, which in relation with another, defines a “space”. Looks like a “Z” on Flat-Flex. Point where the belt hinges. Same as Z bend.
Mesh Sizing designation for Flat-Flex belts, i.e. pitch and the wire diameter.
Metal fatigue How metals fail (and “snap”) after a period of cyclic flexing.
Nose bar  A type of non-rotating end roll, usually UHMW, used for minimum diameter transfer where shaft deflection would be a problem.
Pitch The dimension from the centre of one wire to the centre of the next along the length of the conveyor (measured in mm.).
Polyacetal Ac, otherwise referred to as Acetal or POM
(or acetal)
Strong, thermoplastic with low coefficient of friction. Temperature range -40°C to 65°C. Good balance of mechanical and chemical properties.
Reverse bend  Same as reverse roll, or reverse shaft. The path Flat-Flex belt takes when it is flexed in the opposite direction from a normal transfer.  Typically, this is a shaft used to increase the wrap around a drive or to assist the belt’s change of direction.
Reverse Crown A Flat-Flex, pre-stressed with a negative camber across the width of the belt, usually done on a “hold down” belt.
SLE Single loop edge. This is the standard Flat-Flex edge configuration.
Shuttle conveyor These conveyors constantly push the belt and then retract to discharge/drop product in lanes. Used to spread product across wide belts from a single lane product supply.
Space The distance between the centre of two adjacent belt joints or Z-bends in Flat-Flex belts.
Sprocket A machined part with any number of teeth, as on the rim of a wheel, arranged to fit and engage Flat-Flex belts. They are specifically made to fit on a shaft that together with the sprocket positively drives the belt.
Tensile A measurement of the “pull” strength (to failure) of a material.
Tension A measure of “pull” in a system.
Transfer rollers Spool shaped rollers that turn freely on a shaft where Flat-Flex joints run in the groove.
UHMW Ultra high molecular weight. This is a high-density polyethylene resin used in the manufacture of wear strips with excellent wear characteristics.
USDA United States Department of Agriculture. Federal agency that regulates equipment that may be employed in meat, dairy and poultry processing.
Wear strips Plastic or metal strips that the belt rides on to increase the useful life of the frame and prevent wear to the conveyor belting.
Wire Metal drawn into a very long thread or rod, usually circular in cross section.
Wrap The amount of belt in contact with the drive sprocket; normally 180°, but could range between 120 to 220°.
Z bend The bend in the wire, which in relation with another, defines a “space”. Looks like a “Z”. Point where the belt hinges.  (Same as  joint)
