Abstract: An apparatus for assembling and packaging mail items, comprising a transport track which includes an endless conveyor with mail item forwarding projections and a conveyor drive, as well as at least one feeding device with a feeding device drive, which feeding device is arranged above and in-line with the transport track for the purpose of feeding documents, such as for instance supplements, the feeding device comprising a feeding device delivery gap located some distance above a transport surface formed by the transport track, characterized by a document guiding device arranged downstream of the feeding device delivery gap, which document guiding device comprises a first endless conveyor and a second endless conveyor each having a portion of a transport part in mutual abutment and thus forming a document guiding path bounded by a document guiding path infeed gap and a document guiding path delivery gap, with a drive of the first and the second endless conveyor being independent of the feeding device drive, an

Abstract: The cotton module builder comprises a mobile, open-bottomed rectangular frame structure into which field cotton can be deposited. A compacting mechanism is mounted at the open top of the frame structure in order to compress the cotton therein into a compact, self-supporting stack (or module) which can be left in the field when the module builder is moved to a new location. The stack can then be picked up later and transported to a cotton gin.An improved side frame structure for the module builder increases the structural rigidity thereof and includes a continuous side wall beam of triangular cross sectional configuration interconnecting the side wall struts. This beam provides high torsional resistance and minimizes the horizontal deflections at the base of the vehicle, especially when the rear door of the module builder is open as when the stack or module of cotton is being deposited in the field.
