C.4 Calculating Line Speeds
The following table is a general reference to line speeds, showing line
speeds in metres per second according to the product pitch (gap between
products), and the products per minute.
Figure C-3 Line Speed per Product Frequency
C.3.1 Calculation Formula
The formula used to calculate the line speed is defined below, together with
an example. The formula can be used to calculate the speed of specific
product pitches and/or product frequencies not shown in the above table.
Line Speed (m/s)
OR
Line Speed (m/s)
= Number of products per second
Number of products per metre
= Number of products per second x Pitch between
products (in metres)
