2. Calculation of different parameters in Knitting from given notation
diagram
Needle Arrangement: 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 ......
Find out the following parameters:
1) Total no of Needle
2) No of active and inactive needle
3) Total no of cam box
4) No of active and inactive cam box
5) Total no of cam
6) No of knit, tuck and miss cam
Where the machine is 8 truck machine and the machine diameter is (a) 29” (b)
39” (c) 49”
Solution
(a) For 29” machine dia

3. M/C dia D = 29”
Gauge = 24 needle/inch
Total no of needle = πDG
= π × 29 × 24
= 2186.54 ≈ 2187
No of active needle and inactive needle = 2187/8 = 273 × 8 + 3
Active needle = 273 × 8 = 2184
Inactive needle = 3
Total no of cam box = 3D = 3 × 29 = 87
Now cam box repeat = 87/3 = 29
No of active cam box = 3 × 29 = 87
No of inactive cam box = 0
Total no of cam = no of cam box × truck
= 87 × 8
= 696
No of knit cam = 18 × 29 = 522
No of Tuck cam = 6 × 29 = 174
No of miss cam = 0
(b)For 39” machine dia
M/C dia D = 39”
Gauge = 24 needle/inch
Total no of needle = πDG
= π × 39 × 24

4. = 2940.53 ≈ 2941
No of active needle and inactive needle = 2941/8 = 367 × 8 + 5
Active needle = 367 × 8 = 2936
Inactive needle = 5
Total no of cam box = 3D = 3 × 39 = 117
Now cam box repeat = 117/3 = 39
No of active cam box = 3 × 39 = 117
No of inactive cam box = 0
Total no of cam = no of cam box × truck
= 117 × 8
= 936
No of knit cam = 18 × 39 = 702
No of Tuck cam = 6 × 39 = 234
No of miss cam = 0
(c) For 49” machine dia
M/C dia D = 49”
Gauge = 24 needle/inch
Total no of needle = πDG
= π × 49 × 24
= 3694.51 ≈ 3695
No of active needle and inactive needle = 3695/8 = 461 × 8 + 7
Active needle = 461 × 8 = 3688

5. Inactive needle = 7
Total no of cam box = 3D = 3 × 49 = 147
Now cam box repeat = 147/3 = 49
No of active cam box = 3 × 49 = 147
No of inactive cam box = 0
Total no of cam = no of cam box × truck
= 147 × 8
= 1176
No of knit cam = 18 × 49 = 882
No of Tuck cam = 6 × 49 = 284
No of miss cam = 0
