SPREADING
It is a process of laying down many layers of
fabric each on the top of proceeding ones by
several methods and machines as per the fabric
and garment characteristic.

SPREAD
A spread or layup is the total amount of fabric
prepared for a single marker.
The height of spread is limited by :-
Vertical capacity of the spreaderCutting method
Fabric characteristic
Size of order placed

Spreading table should be covered with layer of
paper before the fabric is spread. Reason being:-
Protects the fabric from spots on table surfaces.
Prevents the base plate on the cutting knife fromdistorting lower plies of fabric.

Spreading surface needs to be about 10 inches
wider than the fabric

PIN TABLES
Pin tables have rows of pins located below the
surface that can be extended through slats to
hold fabric in a precise location for accurate
matching of pattern repeats.

VACUUM TABLES
Vacuum tables are used to compress the lay-up
and prevent shifting or movement during cutting.
The spread is covered with plastic film that forms
a seal over the lay-up when a vacuum is applied.
E.g. quilted fabric

AIR FLOATATION TABLE
These tables when activated, allow easy
movement of a lay-up on to an adjacent cutting
area. It reduces friction and allows the lay-up to
be moved easily without putting stress on the
fabric. It helps the operator to shift fabrics likedenim easily.

CONVEYOR TABLES
Servomotor controlled conveyor table. The fabric is
correctly aligned with cutting machine by means
of the conveyor belt

TRANSFER
Transfer tables to move spreading machines to
other tables and feed different cutting lines

FABRIC CONTROL DEVICES IN A
SPREADING MACHINE
Tensioning
It involves synchronizing the rate of spreading
with the rate fabric is unrolled
Positioning devicesThis device and sensors monitor position and
control fabric placement during spreading.
Electronic edge sensors monitor selvages as
fabric is spread. Alignment can be held to 1/8th
inch as tolerance.

Width indicators
It may sound an alarm to alert the operator when
ever fabric becomes narrower than the
established width
End treatment devices
They are used with spreaders but are separate
and placed at the end of the spread. The specific
end treatment equipment needed depends on
whether the spreading mode is face to face or face
one way.

KNIFE BOX
A knife box contains a cutting unit (a small
rotary knife) that operates in a track and cuts
across the fabric width when engaged
