  2. 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.

  3. • 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.

  4. • J-Box. • Twister. • Centering Roller. • Basket with Exhaust Fan. • Knife. • Padder/ Immersion roller. • Turning Roller. • Tension Roller. • Sensors. • Free Roller

  8. • Open the fabric from the rope form. • Reduce the water content • To slit the fabric from tube form • Apply overfeed to give some compaction. • Width-wise stretch the fabric. • Plait the fabric

  14. •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.

  15. 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.

  16. 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 a 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.

  17. Cutting Line Check: Operator checks fabric cutting line. Rotary blade cut fabric through wales line or not. Bow and Slant Check: Operator checks bow and slant at delivery side. Faults Check: As mentioned earlier.

  18. Machine specification: Brand name: CORINO MACCHINE Type/model no: Company: Italy Year: 2005 No of motor: 08

  19. Function of the Machine: 1. Used to remove excess water after pretreatment and dyeing 2. To slit the tube fabric by the knife for opening of the fabric and ready for stentering 3. Delivered fabric is crease free state 4. Before squeezing balloon is formed with the help of compressed air passing by a nozzle or air sprayer 5. It can control the diameter of fabric and GSM and shrinkage by over feeding mechanism 6. To impart soft finish to the fabric by using required softener.

  20. Fabric path of Slitting, De-watering & De-twisting m/c

  21. Production: Capacity: 10 tones/shift Actual production: 7 tones/shift. Utility: 1.Water 2.Electricity 3.Compressed air or Processed air (to form the tube fabric into ballon with a view to remove crease)

  22. Main parts of the machine: • Squeeze roller (to remove water) • Stretcher (to control width) • Over feeding wheels (to control GSM) • De-twisting device (To delivery the fabric roll in untwisted form) • Folding device (to delivery the fabric in folded form) • Squeezing roller • Padder for softener

  23. Controlling points or Control system: •Overfeed control •Pressure •Speed control •Width control Power consumption: Voltage: 400V Frequency: 50Hz Maximum power: 24kwatt Manpower Required: Worker: 02
