摘要： A package of a carbonaceous filament strand in the form of a square-end cheese, which is free from "thread dwell" on the shoulders of the package. The package is formed by distributing turning points of the traverse motions in the area near the package ends. Such distribution of the turning points is achieved by repeating two to six kinds of strokes in a cycle of successive traverse motions. The difference between the maximum and the minimum strokes is preferably within a range of 2% to 20% relative to the maximum stroke.
