Abstract
Methods and apparatus for sensing advancement of a web from a web supply remove the web from the supply in successive distinct and constant increments. Each constant increment is sensed upon its removal from the supply. Advancement of the web is then determined from the sensed constant increments. The requisite constant increments may be provided by advancing web from the supply and selectively arresting the supply to limit the advanced web to the constant increment for each advance.
