Slitting Machine

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. 

Function of the Machine:

•Slitting the fabric to turn tubular fabric to open width fabric.

•Reducing the content water in the fabric.

•Squeezing the fabric for proper chemical penetration. 

Program :

If fabric contain crease mark, padder pressure will be less (Normal pressure 4-5 Bar) or padder will be of(For water finish fabric).

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

Function of main parts

•J-Box:   Squeeze the fabric to reduce the water contains. Water reducing percentage depends on J-Box pressure.

•Detwister:   By the detwister rope formed fabric become untwists form. (due to action of sensor)

•Hand Wheel:   It is manual and used for guiding the rotary blade.

•Turn Wheel:   It controls the fabric rotation

•Rotary Blade:   To cut the fabric through break wales line.

•Ring:   To help cutting.

•Guide Roller:   To guide the fabric to plaiting

•Plaiter:  To plait the fabric.

•Sensor:  Sense for cutting through break wales line. 

Basic Operation Principle: 

The bianco tensionless tubular fabric slitting and opening lines are used after the wash process or the dyeing station.

1.The fabric, placed in a basket in rope form.

2.It is made to pass through the squeezing unit where most of the impregnation liquid is 

extracted.

3.Then it enters the detwister, which eliminates the tension of the rope and is prepared for   

the slitting and spreading processes.

4.The container is placed on a platform whose rotation, synchronized with the action of the 

detwister, untwists the rope preceding the entrance to the detwister.

5.The latter is placed at the top of the structure, for optimal distance from the automatic

slitter, so as to enhance the effectiveness of rope detwisting and spreading.

6.Then the untwist form fabric is transferred to the basket by means of motorized belts and 

then it moves on towards the slitter without stresses that would can be widened upto

a diameter of 80 cm.

7.The cutting line can be controlled by means of basket rotation.

8.From conveyor belt fabric is passed through dogal centering roller (It constitutes 

9.compacata fabric centering system, with faster centering action and enhanced efficacy  

compared to traditional centering devices.

10. The open with fabric is passed through squeezing system to extract the greatest possi-ble

quantity of impregnation liquid from the fabric, by squeezing it between two rub-ber coated

rollers. (It structure is highly compact and sturdy, and it can be made either of iron  or of

stainless steel).

11.  After squeezing the fabric it go to the plaiter to plait on a trolley.
