SECTION-B
2. Draw the coil path of a cylindrical package with Traverse Ratio 2.5, length of traverse
10cm and circumference of package 12cm.
3. Mention the working principle of T.F.O. along with its advantages.
4. Mention the testing and yarn conditioning parameters of USTER Classimat- III.
5. Show that the winding speed remains constant in case of a drum driven cheese.
6. Show mathematically that sley reciprocation does not follow the SHM.
SECTION-C
7. a. A mill manufactures in large quantity warper beams containing 300 kg. and 400 ends
of 400 tex yarn. On an average there are 40 breaks/beam, each taking 1.2 min. to repair
and doffing time per beam is 6 min. The warping speed is 550 meters/ min. If a
magazine creel is in use, determine

ii. The average production in kg per hour.
b. Three yarns- 28
s
, 30
s
& 32
s
are twisted together. The resultant yarn weighsl37 lbs.
