Introduction
Spreading is the process of superimposing
the plies of fabric one over other according to
the predetermined plan.
Spreading speed may affect productivity,
quality and cost of operation
About 40-50% of companies turnover depends
on effective fabric utilization

Requirements of Spreading
• Shade sorting of cloth rolls
• Correct ply direction and adequate lay stability
• Alignment of Plies
• Grain Alignment (bowing)
• Correct Ply Tension
• Elimination of Fabric Faults
• Elimination of Static Electricity
• Avoidance of Fusion of Plies during Cutting

Types of Spreader
It can be categorized into two categories
• Stationary spreaders: portable and fixed
• Traveling spreaders: semi automatic and
automatic
• Stationary spreaders remain in one position on
the table during the spreading process
• Traveling spreaders traverse the length of the
spread during the spreading process

Fabric Control Devices
• These are those mechanisms that control fabric
as it is carried up and down the table and
unrolled by the spreading machine
• These include- Edge sensor
-Tensioning control mechanisms
-Positioning devices
-End treatment devices Width indicator
End catchers Turn table

Fabric Cutting Devices
• Knife box contains a
cutting unit
• Usually a small rotary
knife
• It cuts across the
fabric width when
engaged

Manual Spreading
One operator at each
side of table.
Fabric package
supported on frame.
Operator aligns the
plies manually
Ply cut with hand
shears, circular knife
etc.
Ideal for small-scale
production

Fabrics Preferred for Manual Spreading
• Knitted fabric
• Crepe fabric
• Stretchable fabric (spandex blend)
• Checks
• Stripes
• Regularly repeating pattern etc.
