The drawings illustrate the arrangements of fixed carrying troughing sets with plain or impact rollers,l and the suspended troughing set “garland”.
The carrying troughing sets of three rollers are designed as standard for unidirectional belts, and for this reason have a slight forward inclination of two degrees in the position of the side rollers. This assists the
belt tracking by an autocentralising effect.
For reversible belts the version R is required, which is without the above two degrees.
