Abstract

An apparatus for conveying mail flats in an upright position with at least one conveying module has a circulating, horizontally oriented floor belt guided via return rollers, and two endless lateral guide belts guided via deflection rollers. A distance of the lateral guide belts from one another at ends of the conveying modules is greater than a thickest mail item. A height of a first lateral guide belt is less than that of a second lateral guide belt. Below the first lateral guide belt an elastic, narrow, endless pressure belt is provided, which is resiliently pressed against a lower part of the second lateral guide belt by pressure deflection rollers and pressed away from the second lateral guide belt by the mail items according to their thickness. Guide rails are mounted obliquely to a conveying direction and tangentially to the pressure deflection rollers.
