Abbreviation for "Feet per Minute".
The duration of time in minutes required for one complete cycle of a conveyor belt.
(1) The resistance to motion of a belt due to the contact between two surfaces. (2) Improperly used to indicate the bond between two surfaces.
An impregnation of rubber material calendered by friction motion to a fabric so that the material is forced into the weave of the fabric.
The exposed portion of a belt finished with a layer of impregnated plastic as distinguished from being completely covered with a layer of plastic.

The ration between the force pressing the surfaces together and the force required to move it.
The force which is required to start a body sliding.
Coated with rubber compound on a friction (uneven speed) calender.
Light scattering surface resembling fine crystals.
Full rated tension
An agent that destroys fungi or inhibits their growth.
An irreversible process during which a PVC compound or platisol undergoes a physical change and becomes a homogeneous mixture by the mutual solvation of the PVC resin and the plasticizer in the compound, as result of heating to an appropriate temperature.
