SPEED FRAME ( SIMPLEX)

SPEED FRAME INFORMATION

1. Total draft should be around 10 for 4 over 4 drafting system

2. Better to use floating condenser in the front zone to reduce hairiness and the diameter of the roving

3. Cots buffing should be done once in two months. top roller run out to be checked and it should be nil. There

should not be any compromise on top roller quality. Top roller cost for speed frame is negligible if it is

compared with ring frame.

4. If possible it should be treated with surface treatment like treatment with LIQIMIX or treated with acid to

reduce top clearer waste which is caused by top roller surface

5. Twist Multiplier should be high enough to reduce stretch in Ring frame. Higher the T.M lower the classimat

"H1" faults

6. If single speed for flyer is used, it is advisable to run less than 1000 rpm

7. When the speed frame bobbin is full, flyer speed should be less than 1000 rpm. Otherwise surface cuts will

increase and thin places also will increase

8. False twisters should be changed once in two years. Variation in false twister will result in high count C.V%

9. Roving tension should be as low as possible and as uniform as possible. Higher the roving tension, higher the

count C.V% and higher the thin places

10. Density of all roving bobbins should be same. Higher the variation, higher the count C.V%

11. Break draft should be around 1.18 to 1.24 depending upon the type of drafting system and total draft

12. Roving hank should be decided in such a way that the ring frame draft is around 20 to 34 for different counts.

13. No sliver piecing or roving piecing from speed frame should be worked in Ring frame. All sliver piecing and

roving piecing will result in thin and thick yarn. Some times it may be cut by the clearer, but all yarn faults

created by piecing are not cut by the clearer.
