An automatic bobbin transport system

eliminates handling and manual touching

(avoiding contact with dirt as well), the

need of a great number of spare bobbins

and trolleys for their transportation

and reduce the storage space where

the bobbins can accidentally deteriorate.

Also people are reduced, thus helping

the efficiency of the mill and keeping

the quality at a level which is not

possible to reach without the great

help of an automated system.

High productivity and reduced sliver

breakages during operation.

The pressure on the top roller

is individually adjustable and during

the lap formation the winding speed V1

changes in order to keep constant the

lap count.

Lap formation

The controlled pressure variation

ensures a uniform batt weight

and structure during the lap formation:

a considerable reduction of hairiness

is therefore achieved.

The winding speed changes during lap

build-up keeping the production at the

highest possible rate.

It is possible to reproduce previous

production conditions and maintain

same quality standard minimizing

irregularities.

High Performance With Top Sliver QualityAdvanced Electronic Control

New Pneumatic Drafting Head

Production Setup And Control By Software

CM600N

best quality can be obtained and con-

sequently the production costs are

reduced. In order to achieve greater

improvement both in efficiency and in

quality, the drafting unit (3 over 4 +

1 guidance roller) has been designed

with pneumatic pressures and it is

positioned directly over the sliver

coiler unit.

The technological parameters

are set directly on the touch screen.

All the programs are stored

and can be recalled at any time.

All the electrical components are placed

into a centralised electric panel

for quick check-up and maintenance.

The components are from a unique

supplier of outstanding quality and

reliability.

Marzoli has a long history in cotton

comber design and manufacturing,

and the new comber CM600N is the

result of a massive activity of our

expanded engineering department.

The overall kinematics of the machine

has been revised and upgraded.

The mechanical speed (up to 480

nips/min) has been increased thanks

to a modern mechanical upgrade

of the following parts:

- Frame Of The Combing Head

- Nipper Unit

- Driving Head

- Feeding Rollers

Even the CM600N grants the best

fibres selection thanks to the good

geometry of the combing elements.

With a more effective combing the

CM600N

magnesium alloy: the result is a light

weight of less than 2 kg.

Their shape has been designed for lap

weight of 80 g/m, also ensuring

an absolute nipper uniformity on all lap

length. Finally, any uncontrolled

vibrations are no longer possible.

The study of the new nipper unit has

been performed thanks to a special

micro video camera, which recorded

the basic movements and let analyse

the exact flow of the fibre from the nipper

unit to the detaching rollers during the

combing process.

The result is a full set of optimised

components with higher performance.

Nipper unit

The kinematics has been completely

redesign, in order to achieve the

slowest force of impact during the

closing of the jaws.

The jaws are made of an aluminium

Reduction Of The Maintenance Cycle

Extreme Care In The Manufacturing Details

These diagrams show the improvement

in the acceleration of the nipper unit

(jaws) thanks to the new solution

adopted on the machine.

The solution adopted on the comber

CM600N has a lower acceleration,

thus permitting higher speed with lower

vibration and noise level.

CM600N - Diagram of acceleration of the lower jawSpeed = 500 nips/min

CM500N - Diagram of acceleration of the lower jawSpeed = 400 nips/min

The frame of the combing head has been

completely redesigned using an advanced 3D CAD

software, which permitted the simulation

of the dynamic load of the mechanical parts

moving during the combing process.

Every single component of the frame has been

studied, and the deformation which occurs

during high speed operation has been widely

analysed and reduced. The result is a smooth

operation without vibrations and heavy shocks,

also with reduced uncontrolled deformations.

New Solutions To Boost Performance

Reduction Of The Maintenance Cycle

CM600N

Driving head: jaws

The force of impact of the nipper

jaws has been lowered

thanks to an eccentric compensator,

driven by a twin gearing.

Driving head: nipper unit and

detaching rollers

The nipper jaws have a shorter angular

movement and are driven by a balanced

eccentric gearing.

The detaching rollers are driven with

a twin cam (higher precision) with

oscillator and differential which allows

a longer overlapping (26.4 mm).

Headstock with all gears in oil bath.

A very important innovation in the new

CM600N is the fact that with very

simple mechanical settings the machine

becomes suitable to process all the

range of cottons for combed cotton with

very good results in quality and quantity.

Feeding rollers

The feeding of the cotton can be done

with backward or forward movement.

The solution is new and uses a wide

selection of gearings (feeding values:

4,15 - 4,60 - 5,18 - 5,92 mm/nip).

The rugged profile of the feeding rollers

guarantee an uniform and constant

forwarding of the lap.

NovaMARZOLIVOUK

Detaching rollers 2+2

sliver formation

The two bottom tempered steel

detaching rollers have helical fluting.

The two top detaching rollers have

adjustable pneumatic pressures.

The diameter is conical

(bigger in the middle) so as to perform

a correct nipping all along the length.

In order to prevent damages on the

detaching rollers,

there is a proximity sensor which monitor

the sliver during the condensation

process: in case of error (overlapping

of the sliver or fibre missing),

the machine is immediately stopped.

The sliver formation is done

by condensing rollers.

A plate in stainless steel is used

for slivers guide.

Great Attention To Small Details

CM600N

Linear top comb / Self cleaning type

The shape of the top comb has been optimised, in order

to guarantee a better operation during the passage of

the cotton from the nipper jaws to the detaching rollers.

A high removal of the short fibres and an efficient

neps reduction are performed with every type of cotton,

thanks to a wide variety of different comb density:

23 – 26 – 29 – 32 needles/cm.

Self cleaning top combs are recommended for high

quality: a jet of compressed air automatically cleans

the top comb and eliminates the intervention of

the operator. The frequency of cleaning and the

duration of the air blow are determined by an electro-

mechanical system. It has been studied a new system

to program the cleaning of the combs at high speeds.

New quality monitoring system

A quality monitoring sensor located

at the delivery unit accurately controls

Upon exceeding the programmed

values, the comber immediately stops.

A production chart is available on the

screen.

Pneumatic drafting unit

The comber CM600N is equipped with

a 3-over-4 drafting unit + 1 guidance

roller, driven by timing belt for low

maintenance and noise reduction.

Each top roller has an adjustable

pneumatic pressure (40-80 kg).

The drafting unit is positioned over

the top of the coiler.

The insertion of the sliver into

the condensing funnel and then into

the coiler are automatically managed.

This unit is directly manufactured

from the experience made on the

draw frames UMTN.

The comber CM600N can

be connected to Marzoli Spinvision, the

supervision software based on Microsoft

Windows for the remote control of the

spinning machinery. Real-time production

data (output) and machine status (running

conditions, efficiency, alarms) are collected

for further detailed analysis.

SPINVISION

Can changer

The comber CM600N is equipped with

a pneumatic can changer.

The rotating plate is given a surface

treatment to avoid electrostatic charges

and thus allowing high speed.

The sliver is coiled into a rotating can

(24” x 48” with castors): controlled breakage

of the sliver is done when can changing

takes place (automatic process).

A great sliver content in the cans is ensured

by the sliver compacting device.

The machine can be above floor level with the

delivery of the cans through a slide or sunked

with the delivery of the cans at floor level.
