摘要：An apparatus and a method embodied in a guide for an advancing strand of yarn. The guide retains the strand on a receiver which is supported on a cushion of air. The receiver is pivotally retained between oppod members extending from a ba of the guide. The strand urges the receiver toward the ba and the cushion of air, which is introduced between the members proximate the ba, urges the receiver away from the ba. As the air is vented about the receiver the advancing strand is substantially out of contact with the air to prevent removal of coatings from the strand or entanglement of filaments of the strand. Respon of the receiver to variations in the force exerted thereon by the strand may be programmed by regulating venting of the air about the receiver.
