The document discusses the simplex machine, which attenuates sliver through drafting and applies a small amount of twist before winding the roving onto tapered bobbins suitable for the next processing step. It describes the parts of the simplex machine and its operations, including creeling, drafting, twisting, winding, building, and doffing. Finally, it lists some common names for the simplex machine and manufacturers, and concludes that the simplex machine is important as it prepares fiber into a shape suitable for ring spinning.

5. Simplex is the machine where the sliver is subjected
to one or more attenuating process and the attenuated
sliver receives a small amount of twist and is then
wound on bobbins suitable for creeling at next process..

6. SIMPEX MACHINE

7. 1
• To draft the sliver to reduce weight per unit length.
2
• To make conical or tapper shape of the
bobbin.
3
• To wind twisted strand on the bobbin.

8. Parts of Simplex
1.Bottom steel fluted rollers
2. Top rollers
3. Aprons
4. Pressure arm
5. Cradle assembly
6. Flyer
7.Condencer
8. Top & bottom cleaners
9. Bobbin Rail

9. 1.Creeling:
To feed the sliver by the help of several rows of
driver rollers to the machine.
2.Drafting:
To reduce the unit length of sliver to make it
suitable for ring spinning system.

10. 3.Twisting:
To insert small amount of twist to give required
strength of roving.
4.Winding :
To wind the twisted roving on to bobbin.

11. 5.Building:
To build the roving in bobbin such a form which will
facilitate handling, withdrawing & transfer to the
next process.
6.Doffing :
To replace an empty bobbin at the place of full
roving bobbin.

12. OTHER NAMES OF SIMPLEX MACHINE
1.Speed Frame
2.Roving Frame
3.Fly Frame

13. MANUFACTURERS OF SIMPLEX MACHINE
Rieter-Switzerland
Toyota-Japan
Lakhsmi machinery works-India
China textile machinery works
Marzoli-Itali

14. CONCLUSION
• Speed frame is the first machine
which enables the winding of the
fibrous material on to a package.
From this machine the fibre gets a
circular shape which is very
advantageous to be used in ring
spinning. So the importance of
this machine is very much.
