The document describes a modern blowroom line consisting of machines from Rieter, including a bale opener, pre-cleaner, homogeneous mixer, precision blender, storage and feeding machine, condenser, card, and sliver coiler. It provides details on the functions of the Rieter bale opener, pre-cleaner, mixer, blender, storage machine, and condenser and card, which work together to open, clean, blend, feed, and condense cotton fibers into sliver in the blowroom process.

5. Blow room consists of a number of machines used
in succession to open and clean the cotton fiber to
the required degree. 40to70% trashes are
removed in this action
.

6. BLOW ROOM SECTION:

A section in which
the supplied
compressed bales are
opened, cleaned and
blending or mixing to
form uniforms lap of
specific length is called
Blow room section.
This is the first section
of the spinning line.

WE WILL NOW DESCRIBE ABOUT RIETER CO.
MACHINERIES.

9. RIETER

Founded in 1795 by
Johann Jacob Rieter
(1762–1826), the
company initially
produced textile
product.In 1982, Rieter
acquired the British
textile machinery
company Ernest Scragg
& Sons Ltd.

10. IN MOST CASES A MODERN BLOWROOM
LINE CONSISTS OF THE FOLLOWING
MACHINES:
Rieter blowroom line:
1.Bale opener UNIfloc A 11;
2. Pre-cleaner UNIclean B
12;
3. Homogenous mixer
UNImix B 75;
4. Storage and feeding
machine UNIstore A 78;
5. Condenser A 21;
6. Card C 60;
7. Sliver Coiler CBA 4

11. A 11 UNIFLOC AUTOMATIC BALE OPENER:




The UNIfloc A 11 is designed
for output of up to 1400 kg/h.
Bales are laid down over a
length of 7.2-47.2 meters.
The unifloc A 11 can process
up to 4 assortments
simultaneously.
The width of the take off unit
can be selected between
1700-2300 mm.

12. B 12 UNICLEAN PRE-CLEANER:
fiber yield with
simultaneous efficient
cleaning is up to2%
higher than on
conventional units.
Pre-cleaning without
nipping and the use of
mote knives results in
fiber preserving cleaning.
The large dedusting
surface ensure intensive
dedusting even at high
production performance.

13. B 72 / B 76 UNIMIX HOMOGENEOUS
MIXER:
1)The B 72 / B 76 mixing
machine of the bale feed in a
minimum of space even with
unfavorable bale lay-down.
2)eight mixing champers
ensure not only effective
mixing but also high
production performance.
3)T he easy addition of an
opening of cleaner module
provides flexibility with the
capability to respond to
changes in market
conditions.

14. SALIENT FEATURE OF MODERN MIXER :



1. Perfect and homogeneous blending.
2. Simultaneous mixing by doubling over
an extended period of time is achieved in
the case of Aeromixer .
3. In auto mixer, stack mixing principle is
adopted and it permits a controlled
accumulation and doubling of different
layers of material and uniform thorough
blending of material is achieved (ten times
greater than conventional mixer). For
details of salient features of modern
beater, improved openers, automatic
scutcher & automatic lap doffing .

15. A 81 UNIBLEND PRECISION
BLENDER:
 The
UNIblend A 81
precision blender sets
the highest standard for
multi-component
blending with an
accuracy featuring less
than 1 % deviation. The
UNIblend A 81 enables
four different carding
lines to be supplied with
different blends.

16. A 79 UNISTORE STORAGE AND FEEDING MACHINE :

The A 79 UNIstore combined
storage, opening and cleaning
machine processes natural
and synthetic staple fibers up
to 65 mm easily and
efficiently with an output of
up to 1 200 kg/h. Two
versions are available: the A
79S serves to open the tufts,
the A 79R additionally cleans
the tufts.

17. CHUTE FEED
The
Pressure
Transducer will sense
the air pressure of the
main duct line
supplying material
from Blow Room to
Chutes.

18. CONDENSER A 21 & CARD C 60 RESPECTIVELY
 The
other machines of
RIETER blowroomline
is –
 (i)Condenser A 21
 (ii)Card C 60
