                   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.

           SPINVISION

The lap winder LW2N 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.

           Lap transport system


A lap trolley for 4 laps is normally used to manually
move the cotton laps and feed the combers.




     Automatic lap transport system


Laps are automatically moved from lap winder
to combers, avoiding laps manual handling and
saving times during the movement.

      Frame of the combing head

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.

      Innovative Mechanical Engineering
      New Solutions To Boost Performance
      Reduction Of The Maintenance Cycle

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.

                                             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

                                      detaching rollers have helical fluting.
                                      The two top detaching rollers have

                                      (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

                                      the machine is immediately stopped.
                                      The sliver formation is done
                                      by condensing rollers.
                                      A plate in stainless steel is used
                                      for slivers guide.
        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.



   Circular half lap comb

Two types of half comb:
STAEDTLER VARIO
4 sectors (90° combing angle)
The sectors can be combined
according to the fibre type, and the
pin density between the strips
depends on the desired noil %
NITTO UNICOMB
Clothed surface at 90°,
with different pin density.

     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.


     New quality monitoring system
     A quality monitoring sensor located
     at the delivery unit accurately controls
     the mass of the delivered sliver.
     Upon exceeding the programmed
     values, the comber immediately stops.
     A production chart is available on the
     screen.


                                                          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.
