Experiment name: Study on the material passage of Ring frame.
Object:
1. To produce required count of yarn from the supplied roving by the drafting.
2. To insert sufficient amount of twist to the yarn.
3. To wind the yarn onto the bobbin.
4. To build the yarn package properly.
Main Parts Ring Frame:
1. Creel
2. Guide roller
3. Trumpet
4. Drafting rollers
5. Yarn guide
6. Lappet
7. Balloon controlling ring
8. Traveler
9. Ring
10. Spindle
Specification:
I. Name of manufacturer: Platts.
II. No of spindle: 64
III. Ring dia: 6.2 cm
IV. Lift of the bobbin: 9”

Description:
The feed material come from speed frame i.e. roving bobbin is placed on the creel. The creel which is attached to the machine is umbrella type. Then feed material is passed under the guide rollers and through the trumpet in to the drafting zone. Here some draft is inserted in to the roving. The draft system is 3 over 3 drafting system with apron. The delivery material that is delivered from the front roller is reached to the traveler over pneumatic waste collector, lappet and through balloon controlling ring. Lappet is used to control the material path and balloon controlling ring is used to control the balloon formation and spinning tension. Here roving is twisted by the movement of the traveler around the ring. The yarn is then wound on the ring cop.
Conclusion:
Our teacher and lab assistants are very much helpful to us. Their well teaching and instruction help us greatly to understand this practical. I think this practical will be very helpful in my future career.
