# How to Calculate Combing Machine Production

Combing:
The process of straightening and parallelizing fibers and the removal of short fibers and impurities by using a comb on combs assisted by brushes and rollers is called combing. Its main purpose is to remove short fiber than a predetermined length so as to enable the spinner to produce finer yarn.

### How to Calculate Combing Machine Production

Example: Calculate the production per day of a combing machine.

when,
Nip/min = 220
Feed/nip = 7mm
Lap weight = 1000 frains/yd
Efficiency = 90%
Noil = 15%

Solution:

Given that,
Nip/min = 220

Feed/nip = 7mm nip
= 0.007m
= 0.007 X 1.09 yds
= 0.00763 yds

Feed lap weight = 1000 grains/yds

……1000
= …………. Lbs/yds
……7000

Efficiency = 90%

……90
= ………
…..100

Noil % = 15

Production per day,
………………………………………………………………………………………………………100-Noil%
= Nip/min X Feed/nip X No. of head X Feed lap weight X Efficiency X ……………….. X 60 X 24
…………………………………………………………………………………………………………….100

…………………………………..1000……..90…….100-15
= 220 X 0.00763 X 8 X ……….. X ………. X ………… X 60 X 24 lbs
………………………………….7000…….100……….100

= 2113.31 lbs (ANS)

The objective of Combing is to take fibers shorter than a predetermined length. As a result, every bit to enable spinner to arrive at finer yarn than that tin shipping away move spun from the same carded sliver. To take neps as well as impurities, arrive at the uniform sliver of required wt /unit length, brand the fiber instantly as well as parallel. So that yarn buys the farm fifty-fifty as well as lustrous.

The combing process is carried out inwards guild to improve the character of the silver coming out of the card. The procedure eliminates brusk fibers, achieves amend parallelization of fibers. It straightens curls, removes neps and residuum impurities. It is clear from these functions that the combing procedure is essentially aimed at obtaining splendid character yarns and to fulfill this objective raw material amongst higher upwardly average physical as well as mechanical features must move used from the real commencement of the spinning process.
