Top fabric: Increases flexibility, provides wear resistance
on backside idlers, and joins the belt together.
Cogged: Cogs provide increased flexibility and enhanced
airflow for cooler running for specific types of belts and applications.
Insulation: This component surrounds the tensile cords
to ensure the best possible bond
Cushion/fiber loading: Provides the necessary support
for the cords, preventing distortion and collapsing of the belt.
It provides unidirectional support which helps resists abrasion,
reduces noise and controls the coefficient of friction.
Tensile cord: The material that carries the load of the
belt. Constructed of the strongest Kevlar or polyester material to
reduce the possibility of shrinkage or stretch.
Envelope: Provides a long-wearing driving surface and
the proper coefficient of friction.
