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.

A device for stretching a rove of fibers during a spinning operation to permit forming the rove into spun yarn, comprising:
- a condenser element located apart from and placed after a means for stretching the rove, wherein said condenser element comprises a movable guiding surface, upon which the fibers are delivered tangentially, said guiding surface permits a pulling force to be exerted on an end of the fibers coming out of the means for stretching and limits the twist run-back communicated by the spinning system.
A device for stretching a rove of fibers during a spinning operation to permit forming the rove into spun yarn, comprising:
- a condenser element located apart from and placed after a means for stretching the rove, wherein said condenser element comprises a movable guiding surface being in the form of a rotary guide, said guide being provided on its periphery with a substantially V-shaped open groove, upon which the fibers are delivered tangentially, said guiding surface permits a pulling 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.
