Untwisting: A small length of both the ends is untwisted by any mechanism.
Intermingling: The untwisted ends are intermingled together by a suitable mechanism.
Retwisting: The intermingled fibres of both the ends are twisted together again.
In this way, the splicing of broken ends gets completed. The various kinds of splicing devices getting used in textile industries are given below:
1 - Untwisting of fibres of both tails.
2 - Drafting of fibres of both untwisted tails.
3 - Re-twisting of drafted fibres of both tails.
Working procedure of mechanical splicer
When two ends of yarn are introduced between the two disks, first of all, the fibres of both the ends are untwisted, in next stage, the untwisted fibres are drafted well. Now the fibres are brought together to create the centre. The extra yarn on the both ends is unstrung the yarn ends and re-joining of spliced yarn together takes place. This yarn joint gets re-twisted next. The disks are open now and both the ends of yarn are gotten spliced together. In this splicing device, the quality of the spliced yarn does not get affected by the presence of wax on the yarn surface. A protection cover is used to prevent the dust to enter in it. The protection cover opens only when splicing is getting performed.
The air and water are used to splice a single and plied cotton yarns and blends by applying the appropriate mingling chamber in the aqua splicing. The Mesdan company is offering such types of splicers. The aqua splicing device has the capability to join (splice) the all count range and all types of yarns.
