DEFINITION

Classification: 57/58.84

(under subclass 58.83) Means in which the strand is controlled by winding on a drum or pulley co-axial with the flyer.

(1) Note. The strand winds and unwinds in response to variations in tension in the loop, thus providing "storage in transit" for a variable amount of running strand material.
