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[…]
Woven fabric is produced by the weaving process in the weaving mills. Sectional warping is an important process in these weaving mills. It is used to produce warp beams for weaving. So it is the preliminary process of weaving. In this article, we will learn about the sectional warping machine working process. Introduction The sectional warping[…]
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[…]

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[…]
