This document provides information about various finishing machines used after fabric production. It describes the slitting machine, which opens tubular fabric into open width. It also describes the squeezing machine, which extracts water from dyed fabric. Finally, it outlines the stenter machine, dryer machine, and hot air circulation systems, which apply heat to dry fabrics and set chemicals. The main purpose of these machines is to finish fabrics by opening, squeezing, drying, and setting them for further processing or end use.

3. Finishing:

4. slitting machine
• The slitting machine is used in processing fabrics
in the open line in the fishing section. The slitting
machine consists of a blade and a sensor
attached to the blade which indicates the needle
line during slit opening the fabric for processing.
In the slitting machine the fabric is passed
through the twister over the basket containing
exhaust fan for circular dropping of the fabric and
the blade for cutting the needle line of the fabric
and then from the padder and immersion roller
through to the turning and delivery roller. Finally
the open width fabric is delivered.

5. Function of the Machine:
• Slitting the fabric to turn tubular fabric to
open width fabric.
• Softening the fabric by applying softeners.
• Reducing the content water in the fabric.
• Squeezing the fabric for proper chemical
penetration.

6. Main Parts of the Machine:
• J-Box.
• Twister.
• Centering Roller.
• Basket with Exhaust Fan.
• Knife.
• Padder/ Immersion roller.
• Turning Roller.
• Tension Roller.
• Sensors.
• Free Roller

9. Squeezing Machine
• Squeezing machine is used for extracting water from
dyed fabric by squeezing through rollers having
different pressure. Squeezer machine designed to
extract water from piece goods treated in rope form.
They are used as an intermediate devices such as
washers or autonomous devices. In the latter case they
are usually full-width squeezers. The first padder rollers
gives proper squeeze to the fabric and extracts the
water and the second squeeze roller passes the fabric
half the speed of the first squeeze roller which causes
the softener chemicals to properly pass into the fabric.

10. Function of the Machine:
• To reduce fabric surface water content.
• Squeezing the fabric for proper softening
chemical penetration.
• Applying softening chemicals to the fabric.

11. Main Parts of the machine
• Polyreference or Centering roller.
• Bello.
• Bello Alarm.
• Chemical Tank.
• Tension roller
• Squeezing roller.
• Guide Belt.
• Guide Roller.

14. Stenter Machine:
• The Stenter machine consist of 7 drying
chambers, padder rollers and a weft straightening
section which enables the machine to control
Spirality, Shrinkage, GSM during the fabric
passage. During processing first the fabric is
passed through the padding section or squeezer
for properly squeezing the fabric and processing
softening treatment of the fabric through feed
roller and guide roller. Then it goes through the
weft straightening section where by bowing roller
fabric spirality is controlled and then passed
through chain rail for shrinkage control.

15. Function of the Machine
• To make the fabric dry.
• For heat setting in case of Lycra, Viscose fabric.
• To Control Fabric GSM.
• To control Shrinkage.
• To Control Spirality.
• To control fabric Diameter.
• To make the fabric soft by applying chemical.
• Width control.

16. Main Parts of the Machine:
• Heating Chamber.
• Blower
• Width Control Device.
• Biasing Unit
• Selvedge Trimming Device.
• Softener Application Tank.
• Divider Box
• Guide roller.
• Finger Roller.
• Rider Brush.
• Blower.
• Over feed Roller.
• Bowing Roller.
• Photocell.

19. Dryer Machine
• Dryer machine is used for removing the
residual water contained in the fabric after
squeezing by applying heat on the fabric. In
this machine the fabric is fed on the drying net
at low over feed speed and the humidity is
continuously measured. Drying is done by
applying heat through burner nozzles. During
drying the total heat passed through the
machine is extracted by the exhaust fan

20. Functions:
• To dry the fabric with the help of blower and
burner.
• To control the shrinkage of the fabric.
• To prepare the fabric for next subsequent
process.
• To dry fabric without tension.
• To remove residual water containing in the
fabric.

21. Main Parts of the Machine:
• Drying Net.
• Heating Chamber:
• Blower.
• Burner.
• Free Roller.
• Centering Roller.
• Scroll Roller.
• Folder.
• Rubber Belt for fabric delivery.
• Exhaust fan.

24. Hot Air Circulation System:
• In Stenter and Dryer machines air is recirculated which
passes from the exhaust stubs and air controller flaps.
Then the air is passed over the nozzles through which
fabric is passed and routes it over to the heat
exchanger which lets the air to be heated by the
burner. The circulating air fan allows the hot air to pass
uniformly through the nozzles to the fabric where the
air controller flaps control the upper and lower nozzle
air and thus the fabric is heated. Finally the used hot
air is passed on to the exhaust air duct.
