ABSTRACT:
An apparatus for making a yarn consists of at least one ring spinning mechanism and a drawing mechanism, which precedes the ring spinning mechanism and defines at least one draft path for drawing a fibrous roving and includes two delivery rollers defining a clamping nip for the drawn roving, wherein one of said delivery rollers constitutes behind the clamping nip a guiding surface for deflecting the drawn roving. In order to increase the strength of the yarn, it is proposed that the delivery roller which constitutes the guiding surface for deflecting the roving constitutes at least near the delivery end of the guiding surface a slideway for guiding the roving transversely to its axis as the roving is twisted between the ring spinning mechanism and the drawing mechanism.
