Simplex Machine is used in the spinning mills. For Ring yarn Simplex machine is necessary. Simplex machine is the machine which converts the drawn sliver into roving form. Simplex process is the previous process of ring spinning process. A slight twist is given onto the roving. We can find different faults in the speed/roving/simplex frame. They […]
Different changes take place in the speed/roving/simplex frame and affects in yarn count. Now we are discussing about it – Draft change pinion (D. C. P): A large wheel reduces the draft and so gives a coarser hank (where the D. C. P is a driven one). Draft constant change pinion: The larger the draft constant change wheel, the greater […]
Roller setting is a very important task in the spinning department. Incorrect settings lead to creation of various problems and hampers spinning conditions. The speed of the leading roller is always greater than the preceding roller. Incorrect setting leads to the variation of weight/unit lengths. If the setting between two pairs of drafting roller is […]
The roller weightings generally applied to the top rollers by a weight hanging below the roller beam are about 20 lbs for a double boss front roller, 14 lbs for a middle roller, and 10 lbs for a back roller, the middle and back rollers may be saddle weighted (spring weighted). In this case, the […]
Suppose, a certain hank is made on a machine and it is desired to change to a higher count. The same sliver or roving is used in the creel. The necessary changes are as follows: Draft: This must be altered in order to make the delivery roving finer. The draft change pinion (D.C.P) will therefore be […]
Cone Drum As each layer of roving is added to the bobbin in the speed frame, its diameter is increased. In flyer leading and bobbin leading frame, it is necessary to increase or decrease the bobbin rpm respectively to maintain a constant surface speed on the bobbin surface as each layer is added to its diameter […]
