Abstract: A yarn guide elbow for directing a yarn or filament in a textile process, such as a texturing process. The yarn guide elbow includes a housing, the housing defining a cavity. The housing is provided with a first opening and a second opening, each of which communicate with the cavity. A roller is disposed within the cavity and mounted on the housing for rotation. Each of the first and second openings are disposed substantially adjacent the periphery of the roller. The housing is arranged and configured such that the distance between the first and second openings may be selectively adjusted.
