Winding is one of the most important operation

� Winding is one of the most important operation, which occurred finally in spinning section. � The creation of desired yarn packages that can be easily unwound, is called winding. � This makes usage of yarn on subsequent machines easier and more economical. � Three zones are present in winding machine: 1. Unwinding zone 2. Tension and clearing zone 3. Winding zone

� To prepare the desired package of shape, size and required density. � To remove spinning faults. � To apply wax � To improve if required to yarn. the quality of yarn

There are two types of winding 1. Spindle drive: Where the spindle upon which the package is placed is driven directly. (a) Constant speed winder (b) Variable speed winder 2. Friction drive: where the spindle upon which the package is placed is free to rotate and package is driven through friction by contact with a driven drum.

�CRADLE: It hold cone with the help of package holders. Package can be lifted or lowered by using cradle. �Drum: Its a polished surface metallic drum, slightly cone type. It has cut marks or grooves on surface which guide yarn during winding

� Magazine: Magazine is the main component of the autoconer machine its function is to hold the cops for winding. capacity is up to 9 cops. �Tension assembly: Tension assembly provides sufficient tension to the yarn during winding on to cones.

�Yarn clearer: Its function is to removes the faults such as thin and thick places, slubs and neps. �Waste suction pipe: During yarn cutting and splicing it sucks the waste yarn.

�Bobbin plate: The function of plate is to rotate the bobbins one by one. � Bobbin holder: It is a disk type wheel , its functions is to hold the filled bobbins for unwinding process. �Wax motor: Its function is to run wax cake continuously.

�Wax Cake: To provide smooth surface to yarn wax is applied especially to the yarn intended for knitting, the function of wax cake is to apply wax to yarn to depress its hairs and decrease friction between yarn and needle in knitting. �Suction mouth: When ever yarn breaks during winding the package move in opposite direction with slow speed during that time it sucks the broken yarn end from the package and take it for splicing.

�Retie pipe: It take the yarn end from bobbin toward splicing mechanism. �Splicer: The splicing mechanism performs the knot free joining of the two yarn ends after yarn breakage. Now a days air splicing is used.

�Dust removal unit: It collects the dust and fiber fly. �Traveling cleaner: It moves from one end to another end of machine to remove and suck the dust , fly and other contaminant particles and keeps winding unit clean.
