2. Entry structure for feeding fabric to padder

3. One MS section powder coated frame structure

4. One swivel tension arrangement with pair of S.S. pipe

5. One pair E+L make KF2020 pneumatic cloth guiders

2 Bowl Vertical Padder

1. Main frame fabricated from MS plates with box type construction

2. One main roller, 305 mm diameter with ebonite coating running in bearing housed of fixed housing of split construction

3. One top pressure roller, 305 mm diameter with rubber coating shore hardness 75-80 A running in bearing housed of fixed housing of split construction

4. One pair pneumatic cylinders (right and left) for loading the pressure rollers onto the main roller; nip pressure available up to 50 kg/cm applied by pneumatic cylinders for main roller pivoted on pin fixed in main frame control panel for pneumatic control and internal piping the right and left cylinders

5. One trough fabricated from SS-316 with SS 316 guide roller; lifting and lowering mechanism by pneumatics

6. One pneumatic compensator or load cell between padder and fabric draw roller

7. One reduction gearbox, directly coupled to the main roller

8. One 11 kW A.C. motor with invertor

9. One nip guard

Stenter Entry

1. Operators platform

2. Fabric entry system mounting of guide rollers

3. MS fabricated box type body (painted) with powder-coated doors

4. One cross beam with machined and polished plated to rest the rail and enable its free movement based on the signals received from in feed device

5. One driven MS fabric draw roller with antislip fillet, with reduction gearbox coupled to the roller

6. One set SS guide rollers, 140 mm

7. Two operator control cabinets housing push buttons, speed indicators, ampere meters and other controlling buttons

Fabric Transportation

1. One set casted rails with ground finish enabling smooth sliding of the chain; 3300 mm entrance track with ball bearings set

2. One set chain tensioning system

3. One set chain with clip type

4. One set limit switches to control chain tensioning

5. One pair E+L KR 43 photocell with FR 15 sensors for fabric edge sensing and controlling the position of the inlet rails

6. One set pinning device of rubber wheel and brush rollers

7. Seven individual motorized screw spindles with directly coupled geared motors, 0.33 kW motor for adjusting the width by PLC

Dryer

1. Frame structure constructed with heavy angle section

2. Chamber length: 3000 mm each

3. Interiors will be high temperature resistant aluminum painted

4. Vario flow air system: closed circuit air circulation; individual blowers for top and bottom jets - 4 nos. directly couple blower motors per chamber; air ratio between top and bottom jets can be controlled and adjusted easily at fingertip through touch screen at the central control unit

5. Implellers are very small in size which has added advantage of lower maintenance; no mechanical damper, meaning no resistance to air flow giving uniform air distribution widthwise, lengthwise and diagonally; increased air pressure gives higher production

6. Gas fired burners: one per zone of 300 kW each

7. Dual filters: easily removable from outside for cleaning even when the machine is running

8. Box type assembly for panels: no welding in insulation panels avoids heat bridge formation which in turn avoids heat losses and increases drying efficiency; insulation is rockwool with 96 kg/m3 density - 140 mm thick panels

9. Door and panel sealing by silicon

10. Inner walls of the panel are painted with high temperature aluminum paint and outside is powder coated

Cooling and Delivery Section

1. One M.S. fabricated air cooling system with AC motor

2. One set heavy duty bevel gear box rested on machined rails; driven by AC motor; bevel gear box driven by spline shaft and AC motor

3. One controlling knob to adjust the speed of take off roller

4. One driven MS roller with fillet for fabric take off

5. One pair S.S. rollers for fabric threading

6. One small batching arrangement

7. One pair de pinning device

8. One control cabinet consisting of machine digital speed/production display, push buttons to increase/decrease speed, adjust width, plaiting
