Carrier ropes are used on paper and board machines to thread a narrow section of the sheet from the wet end to the dry end of the machine along the tending side. Once the tail has been threaded the full length of the machine, the sheet is widened out to its full width. A safe and efficient carrier rope system requires proper design and set up, proper operation and maintenance, and safe behavior by personnel. This course discusses the proper operation and maintenance. It covers routine inspection items, rope cleaning precautions and techniques, shut down maintenance, rope replacement (with and without the old rope on the machine), putting a rope back on a sheave, safely dealing with sheave failure, and rope splices.
