Classification of Weaving Machines
 Single-phase weaving machines
 Machines with shuttles (looms):
Hand operated (hand looms)
Non-automatic power looms (weft supply in shuttle
changed by hand)
 Automatic weaving machines
Shuttle changing[Rotary batteries, stack batteries, box
loaders or Pirn winder mounted on machine (Unifil)]
Pirn changing
 Shuttle less weaving machines:
Projectile
Rapier (1. Rigid Rapier 2. Flexible Rapier)
Jet Loom (1. Air Jet Loom 2. Water Jet Loom)

Classification of Weaving Machine:
Multiphase weaving machines
 Wave shed machines (Weft way multiphase)
Weft carriers move in straight path
Circular weaving machines (weft carriers travel in
circular path)
 Parallel shed machines (Warp way
multiphase)
Rapier
Air jet.

Development of multiphase loom

1. Shed progresses in waves
2. Sheds from in succession across the width of the loom
3. This type of machine may be flat or circular.
Wave shed machines (Weft way multiphase):

Circular Multiphase Loom:
 4 to 10 Shuttle Pass in a circular path.
 Widely used for producing Circular fabric for sacking or packaging
material (like Polypropylene circular fabric for heavy loading).
 Wave shedding

Starlinger Circular
Loom
 Optimized design and production of
cam drive mechanism, to ensure the
stability of the machine and the long-
running reduced power consumption;
 Selection of the most advanced
automatic latitude compensation
system to improve machine efficiency
and reduce the incidence of rejection;
 Longitude and latitude detection
devices, real-time monitoring of warp,
weft usage, break through, the weft,
to achieve position-indicating when
the weft end, and automatically shut
down;
 Intelligent boost control to replace the
traditional mechanical weft density
gear change
 Repairing broken weft is tough.

Wave Shedding
Mechanism
 Warp shed is divided into segments
 Each shuttle runs in its own shed
 Cam controls the heald frame or wire
segments from inside via pushrods.
 Only plain and twill weave are
possible.
 Heald is connected elastically, by way
of an elastic traction element locked to
the fixed part of the loom.
 Healds of each section are lowerly
locked to a single connection block
which is connected by a spring catch
connector, which is itself connected to
the end of a cam-controlled operating
lever
 Each cam controls a independent set
of connecting block thus a
independent part of a heald frame.

Filling Insertion of Circular Loom:
Mechanical Shuttle drive
 Oscillating reed: It moves the shuttle and
also simultaneously beat up the inserted
weft thread.
 Striking lever type elements: They push the
shuttle through the warp ends of the shed.
 Rack and pinion system: The drive of each
shuttle is given through two especially
designed gears. One of which is attached to
the revolving cylinder, has teeth of special
profile to accommodate small groups of
warp ends as it mashes with the second
pinion attached to the shuttle within the
warp shed.
 Pressure rollers: The act on the warp ends
of the inner shed and through them on the
shuttle.

Electromagnetic
Shuttle Drive
 Magnetic field: This is
set up in the form of a
magnetic field by which
the shuttle is moved.
 Rotating Electromagnet:
this holds the shuttle
firmly through the warp
ends of the inner shed
and caries it when it
rotates.

Beat Up In Circular Loom
 Spiked Wheel: They
reacting through the warp
ends follow the circulating
shuttle and press the weft
thread against the fell of
the fabric.
 Oscillating Drop wires:
They reach through the
warp ends, after the shuttle
pass and push the weft
threads against the fell of
the cloth. They are pushed
down by the next shuttle.

Flat Multiphase Loom
Shed Formation In flat
Multiphase loom:

Weft Insertion In Flat multiphase Loom
 The Contis C2 and Nuovo
Pignone TZP looms use
positive drive from the
roller on an endless chain
track fitting into the
depression in carriers.
 In Ruti 6000 the weft
carrier is driven by reed
dents which applies
pressure to the rear
inclined surface of the
weft carriers. Fig: Weft carriers are driven by Oscillating
Reed Dents (Ruti 6000)

Beat up In Flat Multiphase Loom:
 Beat up is done by rotating or oscillating reeds in
case of flat multiphase loom. These kind of reeds
also aid in the weft carrier drive.
Fig: Rotating Reed for weft Carrier drive and also for
beat up.

Parallel shed machines (Warp way
multiphase)
 a series of individual parallel
sheds are formed across the
warp direction, one behind
the other along the warp each
extending the whole width of
the warp sheet
 These shed approach the fell
of the cloth
 This concept is called
Sequential Shed principle or
multi-linear Shed Principle.
Fig: Parallel shed (Warp Way
multiphase loom).

Shedding Mechanism of Warp way multiphase Loom
 A shedding rotor is used to form
successive parallel sheds.
 The rotor is consists of shed
forming element and Beat up
Elements.
 The weaving shed-forming
elements consist of lamellas which
are provided with seating on their
top sides in which warp threads can
be received. They form Upper shed
 The yarn which miss this position
and take place at the right side of
the lamellas create bottom shed.
 The position of the warp yarn is
selected by a position selection
element.

Position selection
elements with
thread guides for
the respective warp
threads, whereby
these thread guides
can be laterally
moved between at
least two positions
The number of
position selection
devices and no of
heald frame for a
design will be equal.
And threading of the
guide of the position
selection devices will
be same as drawing
order of the design.

Picking mechanism of Weft Thread in warp
way multiphase loom
The Picking mechanism for
the warp way multiphase
loom is of two types.
 By Rapier (Gentilini
Ripomonte Loom).
 By Air Jet (Sulzer Textil
M8300).

Filling Insertion By Air Jet (Sultex M8300)
 The yarn insertion system consists of
a fixed part on the one hand and of a
part rotating along with the weaving
rotor on the other hand.
 In the fixed part are provided yarn
feed- through ducts, in this case
four, respectively, for the respective
weft yarns with fixed entries. Their
outlets open laterally into the part
which rotates along with the weaving
rotor.
 The Weft conveyor ducts formed by
recesses in the weaving shed-
forming elements.
 several relay nozzles are preferably
provided, spread over the length of
the weaving rotor, which promote
the conveyance of the weft threads
through the conveyor ducts.

Beat up of Warp way multiphase loom:
 Beat up in warp way
multiphase loom is
done by the beat up
elements on the
shedding rotor. It
pushes the newly
inserted weft yarns
into the fell of the
cloth.

Multiphase: The future of weaving System:

Fastest Weaving machine in the world:
 Sulzer textil has developed multiphase
weaving machine and brought it to
maturity. The M8300 multiphase
weaving machine is the most cost
efficient of all weaving systems.
 The advantages of the multiphase
machine make their full impact when
warp densities remain unaltered for a
prolonged period of time.
 Printing ground fabric, bed linen, work
apparel, light denim styles can be
produced in this machine.
 warp density of 114 ends/ inch or 45
ends/cm can be produced in this
machine and yarn count 8-40 Ne.

 The M8300 will be used wherever 25-
30 % lower production cost as
compare to single phase air jet
machines.
 M8300 was used exclusively for
staple fibre yarns count range 14.5-
70 tex (8- 40 Ne). The European and
American customers were using
cotton, polyester, viscose, and blends
of these as raw materials, and
producing fabrics in basic weaves and
less elaborate designs. Filament yarn
can also be woven in range of 50 to
330 dtex.

 With the weft insertion rate
up to 2800 picks per/ min
(5400 m/min) are possible
meaning that up to 1500
linear meter of printing
ground fabric can be
produced daily.
 On the basis of practical
observation it is known that
a complete style change on
M8300 is possible in less the
3 hrs.
