A relatively open weave duck of approximately square woven construction made with single or ply yarn.
Formation of a powdery surface condition due to disintegration of surface binder or elastomer due in turn to weathering or other destructive environments.
Short shallow cracks on the surface generally due to effect of destructive action of environmental conditions.

Chute lining
Highly abrasion resistant elastomeric lining in a chute to protect the metal chute from abrasion wear.
Chute slope
Angle relative to the horizontal a chute is inclined.
Cleated belt
Transverse raised sections on a conveyor belt to stabilize material carried up an incline.
Closed belt conveyor
A moving, endless conveyor belt formed into a tubular shape by joining its edges while carrying material, and opening the edges while in motion to receive and discharge material.
Cloth impression

Cluster end
A flat disc idler with several discs adjacent to each other at the ends of the idler.
Coefficient of friction
The ratio of the force required to move a package across a belt surface to the weight of the package.
A tooth on the rim of a wheel or rubber product.
Cogged V-belt
A V-belt cut or produced with a series of evenly spaced V-shaped indentations in the inner face to increase the belt’s flexibility.
Tendency of a material to stick to itself.
Usually a squared end belt piece of full manufacturing length but not full manufacturing width. See also slab belting.
Cold bond cement”” usually is an uncured mixture of varied elastomers
Cold feed
The introduction of plastic pellets into processing equipment without milling.
Cold flex
See low temperature flexing.
Cold flexibility
The relative ease of bending following exposure to low temperature.
Cold flow
Continued deformation under stress. See Creep.
Cold splice/bond
Usually the joining of two or more sub-straits together, using a two-part cement that is chemically cured without using supplemental heat from an external source.
Commercially smooth
A degree of smoothness of an article which is acceptable in accordance with industry practice.
A mixture of a polymer(s) and other materials to give the desired chemical and physical properties in the elastomeric components of a belt.
Compression member
The portion of a belt beneath the pitch line as the belt bends around a pulley.
Compression set
The deformation in a material remaining after it has been subjected to and released from a compressive force.
Quality of power of conducting or transmitting heat or electricity.
Contact stain
When staining occurs on the area of an object directly in contact with the rubber article it is known as “contact stain”.
Continuous bucket elevator
A bucket elevator belt that discharges by gravity over the inverted bottom of the preceding bucket on the descending side of the elevator.
A material or a product of known characteristics included in a series of tests to provide a basis for evaluation of other products.
A system for the continuous movement or transport of bulk materials, packages or objects along a predetermined path.
Conveyor belt
A belt that carries materials from one place to another.
Conveyor belt package deflector
A mechanical diverter placed at an angle across the belt to deflect packages off the belt at specific locations.
Conveyor belt stretch
The increase in belt length which occurs when tension is imposed. Stretch is either elastic or permanent. Elastic stretch is a temporary change in length which varies directly with the pull. Permanent stretch is the residual change in length after tension has been removed; it generally accumulates over a period of time.
Conveyor width
In belt conveyors, the width of a belt.
A substance consisting of molecules characterized by the repetition of two or more types of monomeric units.
Several strands of yarn twisted together.
Cord belt
A belt with inserted textile or steel cords for the longitudinal tension-bearing member.
Cord fabric
A fabric with plied or cabled yarns in the warp direction and a light weight filling yarn spaced only sufficiently to process the fabric.
A natural fiber of high cellulosic content.
In a fabric, the number of warp ends, the number of filling picks, or both in a square inch of fabric.
Counter weight
In conveyor belting, the weight applied to the take-up assembly to maintain proper belt tension.

Cover seam
See cover splice.
Cover splice
The transverse joint formed by connecting two lengths of cover stock.
Cover surface profile
A cross-sectional view of the cover surface.
Cover wear
The loss of material during use due to abrasion, cutting or gouging.
A sharp break or fissure in the surface. Generally due to excessive strain.
A small shallow surface imperfection.
A cover surface with many fissures.
(1) The deformation occurring with the lapse of time in both cured and uncured rubber, in a body under stress in addition to the immediate elastic deformation. Some related terms and properties are stress-relaxation, hysteresis, damping, flow, compression set and viscosity. See Cold Flow.
Creeper drive
An auxiliary drive, usually consisting of a small motor and speed reducer, used to keep a belt conveyor in motion at a very low speed during non-operating periods in extremely cold weather. It is used to prevent freezing of a belt and other components.
The difference between the diameter at the center and at the edges of a pulley or a roll.
Crowned pulley
