The Care and Feeding of a Carrier Rope System - William Kenyon

The dryer groove depth is the major factor in determining carrier rope diameter and style. Typically older machines have a rope groove that can range anywhere from 1/2″ to 1″ deep and 1 1/2″ to 2″ wide. Use of a small-diameter rope in these cans will affect threading, as the rope speed will be considerably lower than the dryer surface.
