Abstract
A device for stretching a rove of fibers during a spinning operation to permit forming the rove into spun yarn, the device comprising a condenser element placed after the actual stretching system. According to the invention, the condensing element is in the form of a movable guiding surface on which the fibers are delivered tangentially, the guiding surface pulling permits a force to be exerted on the end of the fibers coming out of the stretching system and limits the twist run back communicated by the spinning system.
