Summary
This document details the index cycle in modern comber, and how the detaching timing can be altered to cause the fibers to be laid more or less over each other. It also covers lap feeding and feed amount range, as well as piecing, detaching roller distance, and separation of fleece. The optimization of index disc is carried out by analyzing spectrograms.

Index Cycle in Modern Comber Index Cycle in Modern Comber Nipper movement Forward – 0 to 23 Backward – 23 – 36 Total dist. Moved – 52 mm Nipper opening – 12 – 23 Nipper closing – 23 – 32 Index Cycle in Modern Comber Lap feeding Forward feeding - 14 – 23 Backward – 26 – 32 Feed amount range - 4.7 to 5.9 mm Index Cycle in Modern Comber Detaching roller Backward – 10 – 18 Forward - 18 – 28 Piecing – 18 - 23 Detaching roller distance – 60 mm Piecing distance – 31.5 mm Separation of fleece – 23 – 28 Index Cycle in Modern Comber Top comb in action – 18 – 28 Circular comb in action – 32 - 8 Index disk – Setting the overlap With the Index disk the detaching timing can be altered to cause the fibres to be laid more or less over each other. The index disk is graduated from –1 to +2. For short staple cotton a typical setting could be +0.5 whereas for long staple cotton it could be 0.0 or even a negative number Optimization of index disc is carried out analyzing spectrogram
