A winding machine without anti-patterning device has the following particulars:
Cylindrical winding drum diameter: 75 mm
Number of crossing on drum: 2
Rotational speed of the drum: 2860 rev/min
Traverse length: 150 mm
A 3.5 degree constant taper cone is built on the above cone winder with no movement of the point of drive during the package build up. At mean cone diameter of 150 mm the package rev/min is 1375.
The number of times major patterning will occur in producing 200 mm mean diameter package on 40 mm mean diameter core is
