SPREADING MACHINE


2/16

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.


3/16

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

BASIC SPREADING EQUIPMENT

CONSIST OF:-

Spreading surfaces

Spreading machine

Fabric control devices

Fabric cutting devices


5/16

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.


6/16

Spreading surface needs to be about 10 inches

wider than the fabric

TURNTABLE

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.


9/16

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.


11/16

CONVEYOR TABLES

Servomotor controlled conveyor table. The fabric is

correctly aligned with cutting machine by means

of the conveyor belt


12/16

TRANSFER

Transfer tables to move spreading machines to

other tables and feed different cutting lines


13/16

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.


14/16

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.


15/16

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
