SPREADING
8/12/2019 Spreading Details
2/20
INTRODUCTION
The process of rolling out layer after layer of cloth, smoothly
without wrinkles, in such a manner that the selvedge on one
side of the cloth is straight, and parallel to that edge of the
cutting table.
Spreading fabric for cutting may be done in a variety of ways.

Spreading Machines by Mode
A variety of machinery may be used for spreading fabrics.
Although investment is often a concern in choosing
equipment, the deciding factor on what type of spreading
machine is required is made by three factors.
First, what modes of spreading are required of the machine
Second, how critical is the need to spread tension free
Third, how heavy (and what diameter) will the rolls of fabric be (and
what diameter) as they arrive from the mill

AUTOMATIC CHANGING

automatic Turntable
The most common has all the features of the automatic rolling
rack, may use either catchers or a cut-off knife mechanism, and
is self powered.
This machine still requires the spreader to manually rotate thefabric turntable rack when spreading F/F modes of spreading.
And other is The FULLY automatic turntable spreader is also
capable of rotating the fabric as well.

Automatic Rolling Rack
Has a drive motor and end switches that permit the machine to
automatically drive itself from beginning to the end of the
table and back.
The spreader then is required to look for damages during
spreading and manage the rolls of fabric mounting them andchanging them.
These machines may have a ride-on platform for the operator
to travel with the machine saving them from walking all day.

DAMAGE CONTROL MARK SENSORS
Newest advances in spreading systems
Use of automatic sensors to identify damages in the fabric.
Mounted with a sensor that detects the tape as it passes
through the electric edge control eye.
The sensor stops the spreading machine permitting the
spreader to locate the damage and remove it during the
spreading process.
Very much useful in face to face spreading.
Permits higher spreading speeds at the same time.

with Electric Eye and
Catchers
Designed with electric eye edge Sensors that use
a servo motor to shift the rack side to side to align
the selvedge on the control side of the table.This saves the spreader time.
a mechanical catcher device is used (A
mechanized cloth weight that automatically liftsand tucks the fabric under it) which is also a time
saving device.

FABRIC CONTROLLING DEVICES

The Vacuum Table
Revolutionary technology
Replacing the use of cloth weights
Through small holes in the cutting table surface, air is sucked
out of the lay.
This compresses the lay and stabilizes it.

Tubular Knit Fabric
Spreader
Tubular knit fabrics pose a special challenge.
As two layers of fabric are being placed on the table from the
roll simultaneously, a frame is inserted inside the tube of fabric
to control both layers as they pass through the machine.
The frame prevents twisting or folding as the fabric is placedon the table.
Positive feed rollers reduce the tension in the fabric during
spreading.

Air Floatation Tables
Cutting tables that have a system of air jets mounted down the
center of the table.
This facilitates moving either a block, or the entire spread
down the table.
This technology facilitates spreading down the length of a longtable, then easily moving the entire spread to the automatic
cutting system.

FeaturesMachine returns back to original position once fabric runs
empty.
The machine power will automatically shut off upon 5 minutes
idle.
The spread laid fabric is not pulled when the emergency stop
triggers.The streamline shape can reduce the wind disturbance, noise
and vibe ration.
PLC Touch Panel, user-friendly operation system.
Non-tension spreading.Simple operation increases production efficiently and also
ensures the best quality.
Tilting Fabric Bucket enables the fabric loading easier.
