The document is a presentation about Rajasthan Spinning & Weaving Mills Ltd. in Banswara, India. It discusses the introduction of RSWM, the process of spinning which involves several steps from blow room to cheese winding, and how electronics are used in the textile machinery at various stages. These include uses of photocells, thermocouples, PLCs, servomotors, LED displays, and electronic gauges to monitor processes and optimize production.

• Introduction to RSWM ltd.
• Process of SPINNING
• Electronics in Textile machinery
• Conclusion

3. INTRODUCTION TO RSWM LTD.
• Founder of LNJ group, bhilwara
Mr. L.N.jhunjhunwala established
1st textile industry in Rajasthan
named as RSWM ltd.
• Banswara has two
plants-
• One is for Spinning
• 2nd is for weaving

5. ELECTRONICS IN INDUSTRY
1. ELECTRONICS IN BLOW ROOM-
· Photocell Unit offers protection against
variation in line voltage.
· Thermocouple are used in drying room.
· blow room has three
processes. 1)CLEANING
2)MIXING
3)CONTAMINATION REMOVE

6. 2. ELECTRONICS IN CARDING-
· Balance meter based on PLC programming.
· Microprocessor as memory devices.
· fire sensor

7. 3. ELECTRONICS IN DRAW FRAME-
• LVDT as to change the parameter of twisting
according the change in inductance.

9. COMBER FRAME-
• Recalculation and optimization are the
purpose to use C A P D+(computer aided
process development).
• RIETER COMBERs RIETER developed this kind
of computer programs.

10. SPEED FRAME-
• The silver from draw frame is thread with
fewer diameters than silver. It used for rowing
formation. It is wounded on bobbin.
• SERVOMOTORS are used in speed frame.

11. RING FRAME
• Yarn making stage.
• PLC motors used and observed by LED
indicating system.

12. AUTOCORNER-
• Wind yarn from bobbin to cone.
• Splicing or joining of yarn from different
bobbins.
• An electronic gage is available in autocorner
machine to detect the faults.

13. CHEESE WINDING-
• Connect two or more than two yarns parallelly
without any twist.
TFO-(two twist for one circle):
· To minimize the unwanted knots.
· The process gives strength to the thread.
PACKING-
Cartoon packing and pallet packing.

14. CONCLUSION-
• At last I would like to say that practical training
taken at RSWM has broadened my knowledge
and has widened my thinking as a
professional.
