| Select the first letter of the conveyor, conveyor belt or rubber
belting term from the list above to jump to appropriate section of the glossary. |
| - A - |
- A firm or steady contact between two surfaces. In rubber, generally it applies to the
"grab" of rubber to rubber or rubber to metal, fabric, plastics or other
components of a finished product.
The maximum angle at which a given material will stay at
"rest". Example: the angle of stockpile sides.
- Allowable Working Tension.
|
| - B - |
- Bankboard
- A bulkhead mounted on the dozer trap to prevent material from spilling directly onto the
belt and thereby allow a deeper surge pile over a trap.
-
- Backstop
- A device incorporated into the conveyor drive train that prevents belt roll-back in the
event of power loss.
-
- Ball Trays
- Device used to prevent material build up on screen surface of a vibrating screen deck.
Ball trays consist of a series of compartments containing resilent rubber balls.
-
- Belt Feeder
- A short conveyor belt utilized to meter the flow on to the main belt, typically
incorporated into the feeder hopper and feeder trap.
|
| - C - |
- Carcass
- The fabric, cord and or metal reinforcing section of any rubber product such as a belt,
as distinguished from the rubber.
-
- Carding
- "Carding" arranges fibers into a loose rope called a sliver. Many slivers may
be drawn together to form a thin strand called a roving. This roving is twisted on a
spinning frame to form yarn.
-
- Closing Space
- The center-to-center distance between troughing idlers. As the closing space is
reduced belt sag is lessened.
- Coefficient of Friction
- The ratio of the force required to move a package across a belt surface to the weight of
the package.
- Conveyor Frame
The supporting structure for idlers, drive etc., also referred to as
conveyor boom.
- Crowned Pulley
- A pulley with a greater diameter at the center than at the edges.
|
| - D - |
- Declined Conveyor
- A conveyor designed to carry material down hill (slope).
- A unit of weight of a yarn, 9,000 meters weighing one gram is one denier, or 15 denier
yarn weighs 15 grams per 9,000 meters (0.529 ounces per 29,520 feet or 5.59 miles).
- Discharge Hood
- Device attached to discharge end of conveyor to direct material straight down from the
head pulley.
- Drive Pulley
- The drive pulley is used to drive the conveyor belt, may be smooth faced, crowned wing,
or rubber lagged, depending on the friction necessary to drive the belt.

|
| - F - |
- The governmental organization known as the Food and Drug Administration.

|
| - H - |
- Discharge end of a conveyor.
-
- A classification of belts rated at 160 lbs. PIW and over.
|
| - I - |
- Impact Idler
- An idler designed to absorb the impact of material as it is fed onto the conveyor belt.
- Incline Conveyor
- A conveyor carrying material on a uphill slope.
- A type of belt construction similar to that of a solid woven belt, with plies
"interwoven" such that it is impossible to separate them.
|
| - J - |
- Jackleg
- Support structure installed below head end of a portable conveyor to provide additional
support for a vibrating screen, grizzly or pugmill.
|
| - K - |
- (empty)
|
| - L - |
- Lagging
- A smooth or embossed covering on a pulley to increase friction between the belt and the
pulley.
- A belt with a working tension of less than 160 pounds per inch of width.
- A series of rollers over which objects are moved by application of power to all or some
of the rolls.
|
| - M - |
- Refers to one of several measurements of stiffness or resistance to deformation.
- A single extruded strand of material.
- Moderately Oil Resistant.
- Many extruded fine strands of filaments grouped together.
|
| - N - |
- National Industrial Belting Association.
|
| - O - |
- (empty)
|
| - P - |
- Per Inch of width.
|
| - Q - |
- (empty)
|
| - R - |
- A conveyor bed that is formed by a series of rollers.
- Resorcinol-Formaldehyde-Latex is the most commonly used treatment for rubber to fabric
adhesions, but sometimes other coatings such as special resins or isocyanates must be
used. This RFL coating is applied at the fabric mill, where the fabric is dried and heat
set at the same time.
- Rubber Manufacturer's Association, who established specifications for conveyor belt
grades several decades ago. Though many of the early members of that association are no
longer manufacturing belting, those standards have been passed along with suitable changes
to accommodate more "modern" raw materials presently used in belt work.
|
| - S - |
- An additional short length of belting added to an existing belt for repair.
- Styrene-Butadiene Rubbers.
- Belting made in wide widths and long lengths for later slitting into narrower widths and
cutting into shorter lengths.
- A stationary surface on which a belt slides.
- A belt cut to lesser width.
- A pulley adjacent to a drive pulley that increases the arc of contact on the drive
pulley to increase the effectiveness of the drive.
|
| - T - |
- Tail End
- End of conveyor opposite the direction of travel (flow).
- The belt pulley near the loading end of the conveyor system.
- Take-Up
- Device used to apply tension to the conveyor belt.
- Maximum safe working tension recommended by the manufacturer.
- Capable of being repeatedly softened by heating and hardened by cooling and in the
softened state can be shaped by flow.
- Training
- Referring to training a conveyor belt, the belt should ride on all idlers without
skewing, accomplished by proper structural alignment and by adjusting troughing and return
idlers.
- The property of a belt that permits it to conform to the contour of troughing idlers.

- Alternate term for "wire cloth".
