This document discusses recent developments in comber machines. It focuses on increased automation, including fully automatic transport and lap changing systems. It also describes improvements to key machine components like nippers, circular combs, detaching rollers, and drafting systems that have increased production rates and fiber quality while reducing waste. Modern combers now feature highly automated processes, reduced vibrations, self-cleaning top combs, and precision gearing for higher quality sliver production.

2.  Introduction
 Auto-motion
 Auto motion preparatory
 Robo lap
 Nipper
 Circular comber
 Detaching roller
 Drafting system

3. In this challenging world “improvement and
innovation” is the only formula to survive in
ever growing market.
So the main focus of this presentation is to
acquaint you all with the modern
developments in comber.

4.  In general, automation in combing can be
subdivided into:
1.Transport automation and
2.Machine automation.
1. TRANSPORT AUTOMATION :
 Semi-automatic transport and
 Fully automatic transport.

5. Semi auto-motion Full auto-motion

6.  Automation of lap changing and batt piecing was an
engineering challenge some 15 years ago. Succeeded in
solving this problem with its ROBOlap automatic lap
changing and piecing device.
Automatic lap changing and batt piecing

7.  SB D 22 + E 35 Omega lap (Latest)
 Homogeneous lap build-up.
 Good fibre orientation and batt structure.
 Even tension through belt lapping system.
 Fully automated Servo trolleys.
 Prodn 520Kg/hr
 Higher batt Weight till 80g/m

8.  Latest development in Lap changing system

9.  Prodn increased by 2% under same Quality.
 Piecing quality measurably improved.
 Fiber wastage reduced.

10.  In modern combers nipper have to open
more than 8 times/sec.
 General construction of nipper assembly
1. Guide plate
2. Top nipper
3. Bottom nipper
4. Pivot point(a)
5. Spring

11.  Metal used – Aluminum magnesium alloy for side body
& jaws are made of fine steel.
 Introduction of web guide plate near feed roll.
 Distance b/w feed roll & nipper mouth has been
reduced.
 Reduced vibrations.
 Clamping line distance reduced
 Concentric synchronize movement of the nippers

12.  Circular combs mainly the core element.
 They remove short fibers, trash neps &
seed trash. Fibers are parallelized at the
same time.
Advancement
o Ri-Q-Comb from graf.
o Large combing area - 130°.
o Different combs acc. To staple length.

13.  With separately exchangeable segments.
 No. of point increases from 160 up to approx.
900 points/inch.
 Ensured distance of the lower nipper to the
clothing points of the comb remains exactly
the same over the total angle.

14.  Ri-Q-Top top combs.
 Top combs equipped with self cleaning technique.
 Top comb holders are equipped with air flow which blows
even air for self cleaning.
 Sequence can be varied from 2 nips to once in 64 nips.
(2,4,16,32,64).
 Better combing Quality due to 100% cleaned top comb.
 New geometry that matches the curve of detaching
roller.

15.  Helical fluting with larger distance and fine
diagonal.
 Convexly ground, i.e. their centre diameter
is slightly increased.
 Proximity sensor which monitors the sliver in
condensation process.

16.  Clamping line distance reduced.

17. By Reiter
• Top roll diameter
increased(Ø 45MM)
• Steel stripper
• Steel plunger
• Extraction from abv.

18.  By Trutzschler
• Individually controllable pneumatic loading.
• Toothed belt drives ensure
low-maintenance operation
and quiet running.
• Feed top roll remains on the slivers
and thus prevents the slivers from
slipping back
• Pneumatic web threading.

19.  New gear with
compensating elements
for high nip values and
low energy consumption
and use of timing belts.
 For higher precision the detaching rollers are driven
by double cams. An oscillator with differential gear
allows longer overlapping during
piecing
