Abstract

An air processing apparatus is disclosed having a feed roll pulling yarn from a source and feeding it to an air entangler at a feed rate. The yarn is entangled by a high pressure air stream in the air entangler, and a delivery roll pulls the yarn from the entangler at a delivery rate. The rolls are driven independently and independent controls are provided to independently vary the feed rate and the deliver rate to achieve a desired overfeed or underfeed of the yarn. A display shows the ratio of the feed rate to the delivery rate. A slub making apparatus feeds yarn to the entangler from a second source of yarn and includes a tensioner for tensioning the yarn as it is fed to the air entangler. An actuator selectively releases tension on the yarn from the second source so that it is rapidly overfed and the air entangler produces a slub in the entangled yarn.
