Abstract:
1. In an apparatus for processing items of mail initially located in a stack of said items of mail, having a feed station with an item removing device comprising an ejection roller operable to remove an item of mail from said stack in a mail flow direction, the improvement of a modular placement device comprising: a separate modular placement device housing, only for said modular placement device, located upstream, with respect to said mail flow direction, of said feed station; said housing comprising a rear wall with a cavity adjacent to said rear wall; a pressure element mounted to pivot and being configured to be plugged into said cavity; said pressure element being configured to exert a pressure force on said stack in said feed direction that causes a bottommost item of mail in said stack to be pressed against said ejection roller to cause said ejection roller to propel said bottommost item of mail from said stack in said mail flow direction; and said pressure element being configured to change said pressure force by an amount that is dependent on a loss of weight of said stack due to removal of said bottommost item of mail therefrom, to counteract said loss of weight.
