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.

(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

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.

47. Hand Lubrication Points
 The clamp and clamp
support of the tucking-in
devices.
 The clamp and clamp
support of the tucking-in

case of important dust
production).

lubrication of the U-
shaped guides.
 The tucking-in devices.
 The sley bearings.
 The rotary selvedge
device
 The bobbin holders of the
rotary selvedge device.
 The harness guides.
 Transmission mechanism

48. Hand Lubrication points:
 Transmission
mechanism of
harness connection.
 The warp beam
gear.
 The rod guide.
 The bearing of the
tucking-in device.
 The engaging

slipping clutch of
the cloth roll.
 The cloth roll drive
& connection at the
LH and RH machine
side.

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.
