End Margin Pattern
Unfinished & Finished
Due to the layout of punches in perforating tools, when end margins are specified, the perforating process typically results in an unfinished pattern. Because finished end patterns are not always possible, unfinished end patterns are considered industry-standard.
To find out if a desired pattern can be produced with finished ends, contact someone from our customer service department. Except for those tools that automatically produce a finished end pattern, unless otherwise specified, unfinished ends are supplied. Examples of unfinished and finished ends for most hole types are shown below and on the facing page. If margins are not specified, then “Safe Sides, No Ends” in the specified pattern are supplied.
An example of "Safe Sides, No Ends" for 60° Actual Center is shown.
