Abstract: A water feed device for feeding water to a moistener for moistening envelope flaps, which moistener is incorporated into a mail handling machine, the water feed device including a water tank which is mounted on a support and from which a quantity of water flows through a water feed pipe to a water reservoir in which part of a piece of foam is dipped, the quantity of water serving to impregnate the piece of foam for moistening the envelope flaps as they pass between a top surface of the piece of foam and a moistener brush, the water tank support being tilted at a determined angle ? relative to a horizontal reference plane, and the water tank itself being tilted at a determined angle ? relative to the water tank support.

Abstract: A document guiding device for an automatic document feeder for a folding and/or inserting machine, the feeder being of the type including a feeder body support plate extending over a sheet inlet chute, at least two loading trays capable of cooperating with said inlet chute in various modes of operation, at least one of the trays including a tilting base capped by a die, constituted by a lip covered in a rough coating and capable of occupying either a closed position for automatic insertion of documents, or an open position for manual insertion, the device including first deflector means disposed upstream from a document feed roller, cooperating selectively with the tilting base so as to orientate each inserted document directly towards the inlet chute to eliminate any points where the lower edge of the document might catch on the roller, or on the feeder body.
