4. Blow Room
Blow room is the initial process of the spinning operation where
the fibre is opened, cleaned, mixed, micro dust removed and
evened thus passed to carding machine.
Objects of Blow room:
1. To open the baled fibres into small tufts.
2. To clean the fibres by removing the foreign matter as the
waste.
3. To mix thorough the different component fibres of a mixing.
4. To form a compact & uniform sheet of fibres called lap.
5. Basic operation in the Blow room:
1. Opening
2. Cleaning
3. Mixing or Blending
4. Micro dust removal
5. Uniform feed to the carding machine
6. Recycling the waste
8. Blendomat
Blendomat is a system in which, the bale is opened by
tufting.
It contains-
Rolls with teeth
Supporting rolls with teeth
Greed's beside the rolls
Leaver’s are connected with inversion
mechanism.
One suction zone where the tuft cotton are thrown.
9. Working Principle
Here,
A and B are two roll’s which added teeth, C is the grid, 퐷1,퐷2, 퐷3
are the supporting roll’s and 퐸1 and 퐸2 are the leavers of A and B
roll connected with inversion mechanism.
10. Roll (A) and (B) with there fine teeth plug into the top
bale surface. The teeth actually pass through the sits of the
grid (C). Small tufts are picked by the teeth and are
thrown in the suction zone. Roll (A) and (B) work
opposite to each other. When A and B start tufting, both of
they are individually come down upto 10 m.m. on the
bale.

Tuftomat system
1. Modern tuft blending installations hold a key
position in the value chain, because blending
faults often become obvious only after
finishing.
2. Trützschler tuft blending concept relies on
reproducible top blend quality.
3. Ensures the perfect speed when blending
natural and synthetic fibers of different
lengths, fineness's and colours.
4. Mix six components in one process step and
achieve optimal CV values.
13. Advantage of Integrated mixer
Opening with optimum quality chain
Simple and secure operation
Large bale lay-down
Flexible layout of bale groups
14. Advantage:
High capacities up to 2,000 kg/h
Precise the blending ratio.
Blending of up to 6 components per process step
Automatic tarning.
A lot of change in recipe memory.
Direct measurement of weight

17. Uniclean / Pre cleaning
Since removing finer trash particles is difficult, seeds and
bigger trash particles should not be broken. Due to treat
this problem we have to use pre cleaning/uniclean.
18. Unimix
The machine is made up of three parts
1. A storage section
2. An intermediate chamber
3. A delivery section
19. Storage and feeding machine UNIstore A 78

20. Features and functions of UNIstore A 78
• The UNIstore A 78 is used as a storage, dedusting and feeder
machine in the blowroom.
• Its main purpose is to provide intermediate storage for
material in order to ensure trouble-free blowroom operation.
• The UNIstore A 78 is used where a mixing opener proves
unsuitable for financial, technical or technological reasons.
• The structure of the feeding and opening unit guarantees
gentle fiber opening.
• The UNIstore A 78 is used where a mixing opener proves
unsuitable for financial, technical or technological reasons.
• The integration of a mesh screen filter inside the UNIstore A
78 eliminates the transport air, and creates an efficient
dedusting.
22. Features and functions of Card C 60
• Maximum raw material utilization at carding
output of up to 240 kg/h.
• The modular machine design reduces
maintenance-related downtimes to a minimum.
Efficient, gentle removal of trash particles
facilitated by the higher centrifugal forces
generated by the card geometry.
• Automatic sharpening of the card clothing with
the Integrated Grinding System (IGS) for long
clothing service life and consistent sliver quality.
• Gentle processing of man-made fibers and
blends while meeting the highest quality targets
