Q.80- What is the purpose of making Traction Band?
C.80. The slivers from the card come to the draw frame. The thickness (diameter) of the bands is not the same everywhere. There are thin and thick places that follow each other along the band. In the draw frame, removing the unevenness of the belt is only possible by combining (dubbing) 6-8 belts together. Thus, it is seen that the unevenness is largely eliminated by replacing the thick places of some bands and the thin places of others. Bands thickened by dubbing are thinned by applying traction (6-8). Normally the mechanical drafting rate is kept close to the number of draw frames fed, as there is a limitation to the fineness that a sliver can be drawn.

Q.85-Which machine is the Roving Ribbon obtained from?
C.85. Since it is not possible to feed the yarn machine as a band from the draw frame (except for the OE spinning system), the bands need to be thinned a little more.
