Abstract
The tensions in steel ties around compressed Australian-wool export bales vary with the type and weight of wool, the amount of compression, and the tightness of application of the ties. A cube law relating the tie tension and the clean-wool shipping density of a compressed bale has been found. Design data for a variety of packages of wool are presented from which probable tie tensions in projected high-density wool bales may be predicted. Some aspects of safe working practice in banding compressed-wool bales are considered.
