Abstract
A method and device for stacking a plurality of vertically oriented mailpieces into a stack, wherein mailpieces are sequentially received into the back end of the stack. A paddle is used to support the front end of the stack in order to prevent the top mailpieces from falling forward. A conveyor belt is used to move the mailpieces in the stack and relieve the pack pressure so as to allow new mailpieces to join the stack. Information indicative of the mailpiece thickness is provided to a movement control module so that the conveyor belt is moved according to the thickness of the mailpieces received into the stack. As such, the pressure in the stack can be properly adjusted. The thickness information can be obtained from an upstream collator, for example.
