Abstract
The method of detecting a mailpiece of the open mailpiece type such as a non-wrapped magazine consists in causing the mailpiece (3) to pass on edge through a first conveyor (2A) arranged to move the mailpiece (3) by nipping it while holding it tightly over substantially the entire height of the mailpiece, then to pass on edge through a second conveyor (2B) arranged to move the mailpiece (3) by nipping it while leaving a top end (3B) of the mailpiece free to fan out. Two measurements are taken of the thickness of the mailpiece (3) respectively when the mailpiece is in the first conveyor (2A) and when it is in the second conveyor (2B), for the purpose of determining, by differentially comparing the two measurements, whether the mailpiece is an open mailpiece.
