3 Laws of Identity

3.1 identifies the machine should not be produced in the visible range.

3.2 General identification for the following order.

a) the part number, as 1XYZ23456700;

b) specification parts, such as gear module, number of teeth, such as m1.5, Z24;

c) the scope of parts, such as the diameter of the cigarette, filter rod diameter, the length of the filter, cigarette specifications, strip package specifications and so on;
