WARP WINDING PROCESS: Warp winding may be classified into the following categories: • Drum winding • Precision or spindle winding DRUM WINDING: In the drum winding process, the package gets driven negatively. The package is mounted on the spindle which is able to rotate freely. When the surface of the package touches the rotating traverse drum having helical grooves in it, the package starts to rotate due to the surface contact of the drum. In drum winding, the package is formed by a single thread which is laid on the package at an appreciable helix angle so that the layers cross one another and give stability to the package. Since the package is driven through surface contact less elongation in the yarn has occurred. Due to surface contact, there are chances of yarn rupture and hairiness in this process. The drum winding is suitable for spun yarn mainly. The packages formed by this type of winding has low winding density but have more stability. The yarn does not get slipped normally in this winding package during unwinding and handling. Only one coil is used to make these packages. The cross winding method is used in the drum winding process. The package formed by this method has a lower winding density. A minimum amount of yarn is wound. The efficient and uninterrupted unwinding of yarn results in the package. The winding process is so simple and easy to handle. The rate of unwinding is high. The cone, cheese and big spool can be formed by this winding process. ADVANTAGES OF DRUM WINDING: The advantages of the drum winding process are given below: • No need for flanges in the packages. • Efficient yarn unwinding during the various weaving processes. • Stability of package is high. • fewer chances of yarn elongation. DISADVANTAGES OF DRUM WINDING: • The main disadvantages of drum winding are as follows: • A number of turns per inch (degree of twist) in the yarn gets affected in the drum winding process. • Small package size results. • Low winding density of yarn package. • Chances of yarn rupture are possible.
