Adhesion - The clinging, bonding or sticking of two material surfaces to one another.
Breaking Strength - The tensile which the textile yarn or cable, a steel cord, or a belt is at rupture; also called tensile strength.
Carcass - The fabric, cord and/or metal reinforcing section of any rubber product such as a belt, as distinguished from the rubber cover.
Coefficient of Friction - The ratio of the force required to move a package across a belt surface to the weight of the package.
Compound - A mixture of polymer(s) and other materials to give the desired chemical and physical properties in the elastomeric component of belting.
Cover(s) - The outer component(s) of belting.
Crowned Pulley - A pulley with a greater diameter at the center, or other points, than at the edges.
Durometer Hardness - A value which measures the resistance to penentration of an instrument into vulcanized compounds.
Elongation - The measurement of increase in length, expressed as a fraction or percentage of initial length.
Fabric - The structure produced by non-woven, or inter-woven yarns, fibers or filaments.
FDA - The governmental organization known as the Food and Drug Administration.
Interwoven - A type of belt construction similar to that of a solid woven belt, with plies interwoven such that it is impossible to separate them.
Lagging - A smooth or embossed covering on a pulley to increase friction between the belt and the pulley.
Live Roller - A series of rollers over which objects are moved by application of power to all or some of the rolls.
Modulus - Refers to one of several measurements of stiffness or resistance to deformation.
Monofilament - A single extruded strand of material.
Multifilament - Many extruded fine strands of material group together.
Roller Bed - A conveyor bed that is formed by a series of rollers.
Saddle - An additional short length of belting added to an existing belt for repair.
Skim - A layer of compound applied to a fabric.
Slab Belting - Belting made in wide widths and long lengths for later slitting into narrower widths and cutting into shorter lengths.
Slider Bed - A stationary surface on which a belt slides.
Slit Belt - A belt cut to lesser width.
Snubber Pulley - A pulley adjacent to a drive pulley that increases the arc of contact on the drive pulley to increase the effectiveness of the drive.
Tail Pulley - The belt pulley near the loading end of the conveyor system.
Tension Rating - Maximum safe working tension recommended by the manufacturer.
Thermoplastic - Capable of being repeatedly softened by heating and hardened by cooling and in the softened state can be shaped by flow.
Troughability - The property of a belt that permits it to conform to the contour of troughing idlers.
USDA -The governmental organization known as the United States Department of Agriculture.
Vulcanization - A heating process during which a compound becomes less plastic and causes changes in the physical and chemical properties; a general term used when heat and pressure is used to cure an endless splice.
Warp Yarns - The yarns that run lengthwise in a woven fabric or belt.
Weft (fill) - The years that run widthwise in a woven fabric; also called fill(ing) or cross yarns.
