The duck surface of a fabricated article wherein the exposed duck surface is free of any covering.
Bare duck belt
A belt in which at least one side has the exposed duck surface free of any covering.
Bare pulley
A pulley whose face surface is not covered or lagged.
Bareback surface
A belt surface where the textile surface is without any coating. It is usually the back or pulley side of the belt, but the top side could be bareback, as well.
Base belt
The portion of a closed belt in a closed belt conveyor which remains flat and provides the necessary tensile strength.
Basic tension bearing yarns
One of the two warp systems in a straight warp fabric where the warp yarns are substantially without crimp and provide the tensile strength for the belt.
Basket weave
A fabric with ends of yarn side by side in both the warp and filling in a plain weave construction.
Bead rubber
An extruded polymeric compound used to fill the void between butted joint of two pieces of fabric.
A continuous support surface over which a conveyor belt may slide.
A flexible reinforced band placed around two or more pulleys to carry materials from one place to another.
Belt carcass
See carcass.
Belt clamp
Beams or metal plates secured transversely on both sides of belt ends to hold the ends in a desired position.
Belt cleaning device
A scraper or rotating device pressed against the belt surface to remove material stuck to the belt.
Belt coil
See coil.
Belt conveyor
A mechanical system composed of suitable head, tail, bend pulleys and belt idlers or a slider bed to handle bulk materials, packages, or other objects placed directly upon it.
Belt drive
An assembly of power-driven pulley(s) used to transmit torque when initiating and maintaining motion to a conveyor or elevator belt.
Belt duck
An open weave duck made from plied yarns with strength predominately in the warp direction. Used primarily in the manufacture of conveyor belts.
Belt fastener
A mechanical device for holding the ends of belt together. There are a lot of different fasteners on the market.
Belt fleet
The lateral movement of a conveyor belt to either side of its intended path.
Belt grade
A classification of belting according to the quality and properties of the belt cover.
Belt modulus
The ratio of stress to strain.
Belt pitch line
See pitch line.
Belt sag
The amount of vertical deflection of a conveyor belt from a straight line between idlers, usually expressed as a percentage of the center to center spacing of the idlers.
Belt slab
See slab belting.
Belt slip
Differential movement between the pulley surface and the belt.
Belt slope tension
See tension, slope.
Belt surface finish
Final surface condition or structure of the belt.
Belt tracking switch
A limit switch actuated by the edge of a conveyor belt when the belt moves to either side of its centered path.
Belt training idler
An idler having a belt-actuated swivel mechanism to automatically control side drifting of a conveyor belt.
Belt turnover
A system of pulleys arranged to turn a belt over. Frequently used to prevent building-up on return idlers by turning the dirty side (carrying side) up. See also twist.
Belting deflector
A mechanism which deflects the conveyed material off of the belt at specific points along the conveyor.
Belting, flat conveyor
See flat belt.
Bench test
A modified service test in which the service conditions are approximated by means of a simulation in the laboratory.
Bend pulley
A pulley used to change direction of the belt run.
Bending force
The force required to bend a belt under prescribed conditions.
Bending modulus
The force required to induce bending around a specified radius and, hence, a measure of stiffness.
Bias angle
The smaller included angle between the warp yarns of a fabric and the diagonal line across the warp yarns.
Bias cut
A cut of a textile material or belt ends made diagonally at an angle less than 90 degrees to the longitudinal axis.
Bias laid
Material laid on or wrapped around so the warp yarns are at an angle less than 90 degrees to the longitudinal direction.
Bias seam
The seam at which bias cut fabrics are joined together.
Bias splice
Belt splice on an angle less than 90 degrees.
Binder warp yarn
One of the warp systems in a straight warp fabric interlaced with the filling yarn to provide the strength to hold mechanical fasteners.
See nip.
Migration to the surface of plasticizer, waxes or similar materials to form a film or beads. See also Bloom.
A mark, deformity, or injury which impairs the appearance.
A raised spot on the surface or a separation between layers usually forming a void or air-filled space in the vulcanized or laminated article.
A discoloration or change in appearance of the surface of a rubber product caused by the migration of a liquid or solid to the surface. Examples: sulfur bloom, wax bloom. Not to be confused with dust on the surface from external sources.
A blister between plies of an article.
Bolted plate hinge fastener
Steel plates both sides and both ends of two belt ends to be fastened together (secured to the belt with bolts with the ends of the plates constructed into a circular hole for accepting a hinge pin to secure the two ends of the belt(s) together.
See Adhesion.
Enclosure for the loading end of a bucket elevator belt.
(1) Progressive ply delamination. (2) The separation of plies in belting due to flexing.
Bottom cover
The protective rubber cover on the surface contacting the driving mechanism of a conveyor belt.
(1) Curvature from the flat plane on the surface. (2) The deviation from the straight line of the fill yarn in fabric. (3) The deviation from the straight line of a product when unrolled and laid on a flat surface.
A mark or symbol identifying or describing a product and/or manufacturer: may be either embossed, inlaid, or printed.
Breaker ply
An open weave fabric used next to the carcass fabric and/or in the cover to improve the attachment of the cover to the carcass and to improve cover cut and gouge resistance.
Breaking strength
The tensile which a textile yarn or cable, a steel cord, or a belt is at rupture.
Brushed finish
The mechanical removal of any surface impregnation or coating from the belt fabric.
One of the cups on an elevator belt.
Bucket cover
The cover of an elevator belt next to the carrying buckets.
Bucket elevator
Belt with buckets attached. The belts run usually vertically.
Bucket projection
The distance the bucket protrudes beyond an elevator belt.
Buckled ply
A deformed ply, usually the result of a fold or wrinkle, which distorts it from its normal plane.
Buffing marks
The characteristic surface condition after a buffing operation.
In the operation of a flat press, the alternative application and release of ram pressure to vent trapped air and gases.
Butt seam
A seam made by placing the two pieces to be joined edge to edge.
Butt strap joint
The connection of elevator belt ends with a piece of belting the width of the elevator belt placed over the butted belt ends, usually extending under at least two buckets and secured with bolts to the belt.
