Major setting point of carding with their effect
setting of carding machine,carding machine setting, effect of carding setting ,carding machine setting effect
1. Lap guide to feed roller:
Settings: 3/4"-1"
Effects: It controls the
selvedges of web. Higher distance make bad selvedge
2. Feed roller to Licker-in:
Settings: 9- 12 Thio
Effect: For higher staple.
heavy lap, setting will be wider Excessive impurities in lap. setting will be
closer
3. Mote knife to Licker-in:
Setting:
A. Bottom 12-15 Thio.
(Closcr setting for heavy dusts) .
B. Top 10 Thio. (Wider
setting for less impurity)
Effects: The sctting should be
sufficiently elose to remove heavy impurities on the Licker-in surface If the
setting is too wide the mote knives operate inefficiently
4. Licker-in to Cylinder:
Setting: 7 Thio
Effect: The object of this setting
is to transfer the fibres to the cylinder& enable the Licker-in to present
clean teeth to the lap fringe. An unreasonably wide selling would not ensure
removal of the cotton from the R-in & in an extreme case, if the Licker-in
became covered with cotton, its action of taking small tufts of material from
the lap which would be performed inefficiently & neps would be formed rd
Back plate to Cylinder:
4.
Back plate to Cylinder:
Setting:
Bottom 12 Thio
Top 10 Thio
Effect: It influences the air
current. Wider setting. high air current, which makes cloudy web.
5. Flat to Cylinder:
Setting:
10 Thio
Effect: Normal & heavy production
ensure this setting. For light sliver closer setting. tends to produce cleaner
web where an exclusive wide setting result in insufficient removal of neps
& in web. Sometimes 5 points setting occur. For synthetic fibre. Setting
will be wider
6. Doffer to Cylinder:
Setting: 5 Thio
Effect : The object of this
setting is to take all god cotton from evildoer to doffer. A wider setting may
be many fibres go round the cylinder unnceessarily more times & wcaken by
the time they are transferred to doffer & a cloudy web will result. These
closer setting will damage each other & leading hook mav result.
7.
Licker-in to Licker-in undercasing:
Setting: 5/16"
Effect: If the setting is too
wide, a loss of fibre may occur. Close setting increases the fibre extraction
with the waste
8. Cylinder to Cylinder undercasing:
Setting
:
1. Back 12 Thio
2. Middle 32 Thio
3. Front 64 Thio
Effect: These setting influence
air currents & production of fly & too wide setting causes loss of good
fibre All settings are done by leaf gauge
