RBNO - Horizontal Dyeing System

An international best-seller.

European Patent and other patents pending in all developed countries.

High-temperature high-pressure dyeing apparatus with horizontal autoclave and
modular yarn carriers fitted with vertical spindles, RBNO processes all kind of
yarns dyed in conventional machines.

Over 75 complete industrial plants in operation, covering all processing fields,
confirm the outstanding success of the original Bellini design.

Operation at 5.0 kg/cm² pressure,140°C temperature. Internal liquor expansion
and pressurization by compressed air cushion. Loading capacities: from 65 to
1500 kgs. Construction completely in AISI 316 stainless steel.

Flexibility and variable loading

RBNO operates with interchangeable modular carriers for flexible response.
Carriers are interchangeable between machines of different sizes. RBNO can be
loaded between 30% and 100% at almost constant liquor ratio by load reducers.
Modular carriers permit extreme flexibility for dyeing:

-Compressed and rigid yarn packages of different diameters and traverses ·
-Worsted tops and bumps.

Automatic coupling systems with total liquor exchange for dyeing of large
batches.

Ground floor installation.

RBNO can be installed on a normal flat floor.

Elimination of overhead travelling crane, mezzanine or underground pits, special
foundations and sewage systems determines large savings in terms of building and
utilities investment costs.

Rapid plant installation and easy maintenance of all components, due to compact
design.

Easy robotisation by shuttle on rails and gantry robot for package handling. Low
liquor ratio.

Dyeing liquor ratio varies from 1:4 to 1:7 according to package density. Only
the carrier and pump are flooded.

Low liquor ratio saves process water, energy, dyeing chemicals and reduces waste
waters pollution. Liquor ratio can be increased by 30% to speed-up the wash-off
phases.

Patented “Pulse Rinsing” device to reduce water consumption and cycle
duration.

High dyeing quality.

Liquor circulation by helicocentrifugal pump with high flow rate/high head
pressure diagram, equipped with built-in flow direction reversal system and flow
rate regulation device. Intensive liquor exchange allows perfect dyeing
uniformity on high-density large diameter packages.

Liquor flow reversal with motor in operation in same direction. Liquor suction
through internal lateral walls.
