There are two winding principle
of simplex. They are,
- In simplex the bobbin speed must be higher than the flyer speed for winding.
If the flyer
speed is NF and bobbin speed is NB. They according to the
principle:
NB>NF
So, winding on
speed = NB-NF
Then, NW=NB-NF…………(i).
- If the diameter increases due to winding, then the bobbin speed must be decreased.
Let, the
delivery speed = L inch per minute.
At any instant,
the bobbin dia = d inch.
Then the
winding speed, NW = (L/πd)…………(ii).
Now, from the
equation (i) and (ii) we get,
NB-NF = (L/πd).
Then,
L = πd (NB-NF).
Building
Mechanism of Winding: There are three important tasks are occurred for building
on a package,
