Spreading equipment• Spreading table • spreading machine• Shears• Weight bars

Page 3: Spreading ppt

Spreading table• Made of wood or sections of

masonite• Surface should be level and smooth• Telescopic metal table legs to

compensate uneven flooring• Popular widths are 48”and 72”• Vertical tilt tables are obsolete

Manual - Face-up-one-way spreading, Infra-red edge

control ,Permanent and moveable End Catcher

Page 9: Spreading ppt

Stationary spreader• Remain in one position on the

table during spreading process• Obsolete• Consist of two upright supporting

rod which hold bolt of fabric.

Page 10: Spreading ppt

Features• Time consuming method• Require operator at each side of table• Fabric secured by weight or clamps• Fabric cut by shears or end cutter• For cutting checks ,stripes etc,.• Fabric may be spiked on to a series of

sharp spikes set vertically on the spreading table.

Automatic spreading machine

Page 12: Spreading ppt

Automatic - Can travel from table to table for continuous spreading

Page 13: Spreading ppt

Automatic - Built - in loader

Page 14: Spreading ppt

Automatic - Spreading knitted fabric without centre crease

Page 15: Spreading ppt

Loader will transport rolls from the floor to the spreading machine

uprights

Page 16: Spreading ppt

Traveling spreaders• Transverse the length of the spread

during spreading process• Basic components:1. Frame or housing2. Journey or table wheels3. Fabric support rod or platform4. Guide collors – aid in correct unrolling

of fabric

Page 17: Spreading ppt

Features• Motor: to drive carriage• Platform: on which operator rides• Ply cutting device with end catcher: to hold end of ply

in place• Ply counter• Alignment shifter: actuated by photo-electric edge

guide.• A turntable• Direct drive: on the fabric support, synchronized with

the speed of travel, to reduce or eliminate the tension in fabric while spreading.( No stretching of fabric)

• Indirect bolt drive : It pulls the fabric from the bolt. The pull rotate fabric and unwind bolt.

Cond……..• Surface leveling blade• Cloth inspection light unit• Preset spreader for no. of plies with

audible signal• Automatic lifter at the end of the table• Automatic sensing of previously

marked flaws or damages• Spreaders for tubular knitted fabric

Page 19: Spreading ppt

Specifications• Maximum fabric width :2m or 3m• Weight -120 kg• Speed 100m/min• Max height of spread 28 cm• Dead heading: when spreading

machine dispenses fabric when traveling in one direction, but returns to first end without spreading.

Multiple bolt bars• Sandwich spreading • Tandem spreading

Turn table: it is a linkage system which permits which permits the fabric bolt to be rotated laterally
