3. Introduction
 Weaving is best described by inter-
lacing, typically at right angles, two sets
of threads to shape cloth, a rug or else
other types of woven textiles. Today of
course this progression is for the most
part automated in addition to mass
produced, but the quality and the charm
of handmade, hand woven rugs and
clothing is immeasurable. Weaving is an
important process in textile
manufacturing, which manipulates
threads into a plumb interlocking outline,
which forms cloth.

4. Automation
 Automation or automatic control, is the use
of various control systems for operating
equipment such as machinery, processes in
factories, boilers and heat treating ovens,
switching in telephone networks, steering and
stabilization of ships, aircraft and other
applications with minimal or reduced human
intervention. Some processes have been
completely automated.
 The biggest benefit of automation is that it
saves labor, however, it is also used to save
energy and materials and to improve quality,
accuracy and precision.

6. Automation in Weaving
process
 The six production steps winding, warping, sizing,
weaving inspection and packing include 16 points of
automation. Of these, 12 deal with materials handling or
transport. Only four applications deal with automating
the machine operations themselves. This includes
automated process control on the slasher and the
weaving functions of
 Automatic Pick Repair
 Automated Warp breakage Locator
 Computerized Machine Control. Manual assistance is
still required for beam replacement and repair of warp
breaks.
 Implementation of electronic control such as computer
control in automatic looms has simplified operations as
only the conditions such as yarn type and weave, width
need to be input in order for the optimum operations to

7. Machine requirements in
Weaving Automation
 Weaving is the most widely used method of fabric
production for the decoration, clothing and home
furnishing textile sectors. However, technical textiles,
including wire cloth, are also produced on modern
weaving machines.
Irrespective of the weft insertion method used, very high
cycle and acceleration rates are essential for weaving
machines. Furthermore, weaving machines are
characterized by a large number of nonlinear motion
sequences and time-critical starting times. Mechatronic
solutions devised from a combination of mechanical
cams and servo drives for warp let-off and fabric take
up are the modern state of the art. More recently,
harness motion and weft insertion have also been
implemented with individual electric drives in some
instances.[3]

8. Demands on the automation
The demands on the automation are:
 Constant velocity relation between warp let-off and
fabric take-up as a function of the main drive
 Constant thread tension during the process (uniform
fabric quality)
 Weft insertion synchronized precisely with cycle times
 Fast position-oriented supply of weft threads
corresponding to the color selection
 Increase in machine cycle times
 Different weft insertion processes using a projectile, air
jet, or picker
 Short resetting times for lot changes
 Reproducibility of process data
 Pattern data management and preparation

9. Benefits of automation
process
 To attain even faster resetting times, the mechanical cam can
be replaced by a high resolution SIMOTION cam function for
harness motions.
 The technology functions integrated in SIMOTION,
particularly the electronic cam, make it easy to implement the
required motion control easily and safely for the process.
Furthermore, where necessary, they allow motion profiles to
be modified flexibly and with minimum effort.
 Variable user interfaces enable process parameters to be
quickly adapted to the execution system. These data can be
reproduced at any time and assigned according to process
technology. A lot change no longer requires you to make
manual adjustments.
 Tools for commissioning, configuration and diagnostics
integrated in the uniform, scalable SCOUT engineering
system reduce service and configuration times.
 Drive System : The integrated automation and drives
structure is rounded off by the bus-coupled dynamic
SINAMICS S120 drive system and SIMOTICS S-1FT7/1FK7
motors.

10. Features of the automation
solution

11. Woven sample digitized
artwork
With the help of
computer system,
we can analyze the
woven sample
digitized artwork
instead of real
fabric. We can see
image display on-
screen than after
making fabric. We
can weave selection
and sample
matching on
screen.

12. Analyzing the fabric faults by
X-Ray emitter
When fabric
passes through
from fabric take-
off to fabric beam,
we can analyze
the fabric faults
by X-Ray emitter.
We has not to see
the fabric beam by
naked eye ,we can
find out faults by
using automation
process

13. Controlling one or several
looms/sizing machines
We can
controle one
or more
looms/sizing
machines by
our PC.we
can controle
our system in
our room
instead of go
to machines

14. Sketch jacquard design on
image processor
By
automatio
n process,
we can
analyses
sketch
design on
computer
screen as
image
processor

15. On-loom automation process
Figure shows
when loom is
running, we can
control our PC
which things as
below

16. Important of Automation in
the Weaving Sector
 Global competition ensures that only
the fittest survive. Today's weaver
needs to ensure that he/she is able to
manufacture and supply the finest
quality of fabric, at the lowest cost, in
the shortest possible time-frame.
Automation is the only option which
will allow the weaver to attain this
objective.

17. Conclusion
 Automation has resulted in control of
machines electronically from user
friendly interfaces, produce intricate
jacquard fabrics at the speed of
commodity fabrics, inspect fabrics on
loom, use optical and laser detection of
warp break, reduce downtime due to
higher levels of automation and quick
style and warp beam change. The
machine speed upto 1000 rpm is
possible, 5 to 10 times faster than 20
