Picanol introduces a truly new generation of airjet weaving machines, combining the latest available technology with over 30 years of experience in airjet weaving. A completely new electronic control platform, integrating state-of-the-art hard- and software, has been combined with a revolutionary new insertion system.
2. An air-jet loom is a shuttleless modern
loom that uses a jet of air to propel the
weft yarn through the shed. It is one of
two types of fluid-jet looms, the other
being a water-jet loom, which was
developed previously.

33. Let off is done electrically.
An electric motor is used to
perform this action.
Let off motion is very important to
maintain accurate warp tension
Speed of let off motor gradually
increases with the decrease of
beam dia.
34. Suggested value of tension for different warp
count
Warp count ( Ne) Warp tension ( kN)
(for 4464 ends)
6 2.40
7 2.30
8 2.20
9 2.10
10 2.10
12 2.00
14 1.90
16 1.80
20 1.65
30 1.65
35. Calculation warp of tension in case of
multi count warp.
Example: (7oe+9oe+12oe) 4:5:3
Warp tension to be set:
(2.30x4)/12+(2.10x5)/12+(2.00x3)/12
=2.15 KN
37. Take up is done
electronically
Take up is synchronized
with the let off motion
with the help of a servo
motor
Take up = Late off+
crimp %
Servo motor drives the
emery roller Fig: Emery roller driven by servo
motor
38. Warp Stop motion
It is constituted with
drop wire and
electrode.
When drop wire fall
(due to breakage of
warp) on the contact
bar a electronic
circuit and send a
signal to stop the
machine
39. Weft stop motion
Filling yarn is detected
by a filling detector.
FD is constructed with a
light emitting diode and
photo electric sensor .
The filling yarn interrupt
the continuity of light
and photo electric sensor
convert it into a
electronic signal.

45. Types of lubrication:
Splash Lubrication
Circulating
Lubrication
Hand Lubrication
Splash Lubrication:
The parts requiring
continuous lubrication
have been placed inside
housings. These
housings are partially
filled with oil. As a
result of the movement
of certain parts, this oil
is splashed onto other
parts. This is referred
to as splash lubrication.
Maintenance
46. Circulating
Lubrication:
Components that need
to be lubricated
continuously and for
which the splash
lubrication is not
sufficient, are
lubricated by means of
a circulating lubrication
system (oil circuit
supplied from the oil
tank).
Hand Lubrication:
The term "hand
lubrication" refers
to the components
that must be
lubricated manually
at specific
lubrication
intervals.

devices.

49. It is difficult to predict machine operating
temperatures, as these depend on machine running
times, machine efficiency, ambient temperature and
load on the machine (fabric, number of frames,
etc.).
Recommended Machine Temperatures:
The normal machine oil temperature should be less
than 55°C;
The Dobby temperature should be less than 65°C;
The cam motion temperature should be less than
60°C;
And the let off temperature should be less than
50°C.
