FEATURES OF AUTO
SPREADING MACHINES :
• Execute computer order
preciselyTouch Panel Display
• Machine returns to original
position once fabric runs empty
• Brake wires are under two sides
• To control the amount of fabric
• Synchronize the rate of
spreading with the rate
fabric is unrolled
• Electronic edge sensors
monitor selvages as fabric
FABRIC CONTROL DEVICES
• Sound an alarm to alert the
operator whenever fabric becomes
narrower than the established
• End catcher, roller blade
• An overfeed device may be built
into the spreading unit, which
automatically feeds extra material
when a fold is to be made.
FABRIC CONTROL DEVICES
Elements of spreading
Frame or carriage
Wheels travelling in guide rails at the edge of the table
Guide collars to aid the correct unrolling of the fabric
The operator clamps the free end of fabric in line
with the end of the spread
Pushes the spreader to the other end
Cuts off the ply in line with that end
Clamps the beginning of the next ply
Pushes the spreader to the other end and so on.
Include a motor to drive
A platform on which the operator rides
A ply-cutting device with automatic catcher to hold the ends of the ply in
A direct drive on the fabric support, synchronized with the speed of travel,
to reduce tension in the fabric being spread.
Specifications of auto
Maximum fabric width that can be handled is normally 2
m, although extra wide machines capable of handling up
to 3 m are available.
Maximum weight of cloth roll that can be carried by the
larger spreading machines is 120 kg
Maximum spreading speed around 100 m/min
Maximum height of spread cloth 28 cm
When a spreading machine dispenses
fabric when travelling in one direction
but returns to the first end without
spreading to begin the next ply, the
return pass is known as ‘dead heading’.
Enabled the development of more automatic functions
A spreader can be preset to a selected number of plies,
emitting an audible signal when it has reached the selected
number or has come to the end of a piece of fabric.
Automatic turntabling gives automatic spreading even for
corduroys which are normally spread face to face
It repeats the process until it achieves the required number of
This method can be used in conjunction with the automatic
sensing of previously marked flaws and damages.
As the flaw moves past the sensor, the spreader will halt, the
ply cutter will cut across the ply, the spreader will reverse
direction and move back to the nearest splice mark on the
marker plan, and then it will continue its run to the end of the
• May use either catchers or a cut-off knife
mechanism, and is self powered.
• Requires the spreader to manually rotate the
fabric turntable rack when spreading F/F,
N/O/W and F/O/W, N/U/D modes of spreading.
• Capable of rotating the fabric as well
•Matching of checks and stripes in the garment production has always been difficult
and time consuming.
•Traditional methods tend to waste a lot of material, since the patterns are cut out
with a blocking tolerance.
•The task of rearranging the blocked pieces is tedious and expensive.
•The workers involved in this process have to be skilled.
•Each Needle-Bar has pins positioned inside the slots of the table top.
•The Needle-Bars can be moved freely along the length of the table. I.e. they can be
positioned exactly according to the matching requirements of the marker.
•The height of the pins can be adjusted by turning a hand-wheel. So spreading and
pinning becomes convenient, fast and avoids tension in the lay package.
•Reduce fabric consumption
•Improve your efficiency.
•Spreading and matching at the same time
•Do the fine cutting after spreading without relaying
•Fabric savings between 3% and 8% can be achieved (depending on the application)
•Savings in labour time between 30% and 50%
•The demand in the skills of the operators is less.
What is a vacuum table?
In almost all cases, when you are cutting with automated cutting systems, the fabric
is held down using vacuum. Technically the correct thing to say is that the fabric is
held down by lowering the pressure in the cutting table and the pressure
differential between this and the atmosphere applies a strong and even force to the
material on the table. In fact, the pressure differential only needs to be small to give
a very high hold-down force.
The vacuum stops the fabric moving while it is being cut, and makes sure the cut
pieces stay in place while the rest of the job is being cut. With porous fabric, you
cover the fabric with a layer of sacrificial plastic film so the vacuum works properly.
•It facilitates accurate handling of the material to be cut, thus ensuring easy knife
penetration and smooth cutting.
• A sensor detects the if any air leakages are present during the cutting phase.
•The electronic system regulates the vacuum according to different materials to
ensure perfect cutting while maintaining the required pressure.
•Faster return on investment and increase in profits.
Air floatation Table
The force required to move a load over a surface is the product of the weight and
the coefficient of friction. This resistance to movement can be dramatically reduced
by any method that reduces the coefficient of friction.
One such method of reducing the frictional drag is to place a thin film of fluid
between the moving load and supporting surface. Air because of its unlimited
availability and general characteristics is an ideal fluid.
As a result materials handling can be simplified and made considerably more
efficient. In fact, loads weighing hundreds and even thousands of lbs. can be easily
conveyed, positioned or manoeuvred by one workman.
