Rieter is an industrial group based in Winterthur, Switzerland, and operating on a
global scale. Formed in 1795, the company is a leading supplier of short-staple
spinning machinery and technology components, and has the widest product
range in this industrial sector worldwide. Rieter has a presence in 9 countrieswith 18 manufacturing facilities and a worldwide workforce of about 4 500
employees, some 26% of whom are based in Switzerland. The company
comprises two Business Groups: Spun Yarn Systems develops and manufactures
machinery and systems for processing natural and man-made fibers and their
blends into yarn. Rieter seeks to maintain continuous growth in sales andprofitability, primarily by organic growth, but also through strategic alliances and
acquisitions.

A blowroom has its qualitative influence on the end product. Otherwise it would
have an adverse impact on yarn properties. High-performance Rieter blowroom
line enables cheaper material to be used and reduce cost via raw material as yarn
cost depends 50-70 % on raw material. However it is achievable by professional
and competent raw material management. Rieter blow room line promises gentle,
cleaning and blending of the fibers. It is equally efficient for both natural and
synthetic fibre.
Key features of rieter Blowroom line
Effective machine design & operation result
Major energy savings
European technology with worldwide reliability
Automatically controlled & continuous feeding system

Economy
Produces upto 1 400 kg/h
(carded sliver).
Bales are laid down over a length of
7.2 to 47.2 meters. Eliminates labor-intensive manual
alignment of the bales.
Qualit y
Effective cleaning and dedusting by
subsequent machines.
Ensures gentle extraction of the
tufts irrespective of the direction of
rotation of the take-off roller.
Consistent cleaning
F lexibilit y
Erocess up to 4 assortments
simultaneously.
The width of the take-off unit can be
selected between 1 700 and 2 300 mm.
Cottons of all origins and man-made fibers
up to a staple length of 65 mm are pro
The UNIfloc A 11 processes the
fiber material gently and
efficiently into microtufts, from
which impurities can be
removed very readily in thesubsequent processes.
