Abstract
A texturing machine for crimping an advancing yarn and which includes a plurality of processing units and a plurality of feed systems. At least one of the feed systems is formed by a driven feed roll and a rotatable guide roll mounted in cantilever fashion on a machine frame, and about which the yarn is looped. A threading device is associated with the rolls for an initial threadup of the yarn before the start of the process, and by which it is possible to lay the advancing yarn against the circumference of the rolls with a total looping greater than 360°.
