Method for weighing mail pieces

摘要

A method is provided for weighing a series of mail pieces such as letters, flats or a mixture thereof, that are being conveyed through a weighing module. Each mail piece has a length which falls within a range bounded by a maximum length and a minimum length. The mail pieces are conveyed through the weighing module at a substantially constant speed while maintaining a minimum gap between successive mail pieces as the mail pieces pass through the weighing module. The weight of each mail piece is measured during a measurement time when that mail piece is the only mail piece moving on the scale. The scale is sized so that measurement times for mail pieces between the maximum and minimum lengths will vary.
