Abstract
A mail inserter has a first web driver to move a web from a web supply and a second web driver to feed the web to a cutter for cutting the web into sheets, wherein the first and second web drivers have different velocity profiles to allow a web loop to form between the web drivers. The loop is variable between a maximum size and a minimum size. When the loop reaches the minimum size, the first web driver is running at its maximum speed. At this point the first web driver is decelerated at a rate such that when the first web driver stops, the web loop is at its maximum size. The acceleration of the first web driver is at a constant rate which is inversely proportional to the difference between the maximum loop size and the minimum loop size.
