Introduction Roving Frame or Speed Frame or Simplex is the machine of a spinning mill, where the sliver is subjected to one or more attenuating process and the attenuated sliver receives a small amount of twist and is then wound on bobbins. The output product of speed frame machine is called Roving. So it is…
Introduction Drawing is a process by which carded slivers are make up form parallel, remove hook and ultimately converted into drawn sliver. In this process, the sliver is elongated, doubled, leveled when passing through pairs of rollers. The tasks of draw frame are equalizing, parallelizing, blending and dust removing. There are mainly three actions are…
Introduction Carding is a mechanical process that disentangles, clean and intermixes fibers to produce a continuous web or sliver suitable for subsequent processing. This is achieved by passing the fibers between differentially moving surfaces covered with card clothing. In carding, fibers are opened to more or less single fibers. Dust, dirt, small trash particles, nep…
Introduction The section, where the supplied compressed bale is turn into a uniform lap of a particular / specific length by opening, cleaning, mixing and blending is called Blow Room section. It is the first step of spinning. Blowroom consists of a number of machines used in succession to open & clean the cotton fiber…
Experiment name: Study on driving mechanism and production calculation of tappet loom. Introduction: A tappet having a rotary motion depresses a follower and a lever, known respectively as the anti-friction bowl and the treadle arrangement, by means of which the heald shaft is operated. A tappet is a cam having some dwell period which controls…
Production Calculation in Spinning is one of the principal tasks for the production manager who is responsible for spinning the floor. Maximum time textile engineers forget the common spinning production calculation formula. In this article just I want to try to give a production calculation formula in cotton spinning. Spinning is a major and ancient part…
