Spacer is used to introduce the distance between lower edge of the top cradle and bottom apron nose bar which determines the distance between top and bottom aprons. This in turn determines the intensity of pressure applied to the fibers to be under control. Again, pin spacer is made of spacer of different sizes and pin of different heights. Pin that is adjusted on the spacer represents an additional deflection point in the yarn path through the drafting system. In the experiment, 20 tex yarn was produced each time using spacer without pin and using pin spacer. Firstly, spacers of different sizes were used. Then pins of different heights were adjusted with the same spacers and these pin spacers were used to produce yarns. Finally, the properties of the produced yarns were compared in order to analyze the influence of pin spacer on yarn properties in the ring frame.
