摘要：
Bulked and crimped yarn is produced by a process comprising driving heated yarn forward to form an elongated package of compressed yarn, to which yarn is continually added at one end and withdrawn from the other end. The magnitude of the deviation of the position of the take-off end from a predetermined position is measured and used as a control parameter to control the temperature of the heated yarn.
