The STA 40 of small-format delivery is specially designed for
optimal handling of small-format products [final length between two
and about eleven centimeters (0.79 to 4.33 inches)], such as
packaging inserts with multiple folds. This delivery prevent folded
products from "popping up", because they are stacked
against a spring-loaded vertical stop in a horizontal position with
the spine down on the delivery table.
