A method and apparatus for densification of fibrous material such as harvested cotton, preferably by a movement of the cotton continuously through a compacting zone on the harvester. In one aspect of the invention, the fibers are locked by differential translation of portions of the mass of compacted material to prevent a layer of material from springing back after compression. A continuous mat of compressed material with locked fibers is formed into a uniform, high density bale or module on the harvester. A cotton harvester compacting system includes an air system feeding harvested cotton into an accumulation area and to the compacting zone on the harvester. The cotton is compressed and fed through a shear zone which differentially translates the cotton and locks the cotton fibers into a uniform, compact mat. In one embodiment, the mat of compacted cotton is fed to a round baler on the harvester to form a dense round bale or module. In another embodiment, the mat is layered into a rectangular bale or module on the harvester. An in-line horizontal compaction zone allows any existing voids in the in-feed section or voids resulting from compaction or shearing to be closed. A brake zone can be provided after the shear zone to provide adjustable back pressure for improved locked in compaction and web handling integrity. The brake is adjustable to fine tune the system for various cotton types and for different moisture and trash conditions. The accumulation area allows continued harvester operation during brief compacting interruptions, such as during module unloading.

An improved surgical instrument is provided for applying surgical fasteners, such as staples, to human tissue which is particularly suited for applying one or more rows of fasteners across a tissue lumen. The surgical instrument can be used in thoracic and abdominal surgical procedures where access to the surgical site is restricted. The surgical instrument includes an articulated fastener applying assembly mounted on a rotatable and flexible support shaft assembly to provide more convenient access to restricted surgical sites. The fastener applying assembly has a compact construction including a fixed jaw which supports a fastener cartridge and a movable jaw which supports an anvil for clamping the tissue therebetween. The fastener applying assembly includes a pin placement mechanism which is actuated by the movable jaw to control the movement of a tissue retaining pin on the fixed jaw. A dual cam mechanism is provided for driving the fasteners into the tissue clamped between the anvil and the fastener cartridge. The instrument has an actuator handle assembly with an improved actuator mechanism for closing the jaws and driving the fasteners into the tissue.
