Speed Frame Production Calculation
Math 1: Calculate the TPI (twist per inch) produced on a simplex with diameter of front roller 28 mm and its rpm be 30. The rpm of flyer is 1000.
Twisting and Amounts of Twist for Different Materials – why is the amount of twist in a yarn important
The roving coming out of the front delivery roller is threaded through the top of the flyer, passes through its hollow leg around the presser arm on to the bobbin. The purpose of providing twist in roving is to give the strand sufficient strength to withstand the strain during unwinding in the creel of the ring frame. The insertion of twist is achieved by the rotation of the flyer.
Speed Frame and function of speed frame
The output from the draw frame is fed into the roving frame (also called ‘speed frame or simplex machine or flyer frame‘) where the linear density of sliver is reduced by drafting and the resultant product is called the roving. After the drafting operation, the roving is wound on the bobbin. During winding, a little amount of twist is imparted to the roving.
