Abstract: Surgical stapling methods and tools which allow a surgeon to create several different predetermined amounts of tissue constriction using the same staple (11) loaded in such a tool (31). A stapling tool (31) holding one or more staples in an effector section (35) contains a mechanism for spreading the pointed ends of a staple to one of several spaced apart distances as controlled by an actuator-indicator (43). Depending upon the distance the pointed ends have been spread when the staple is implanted into tissue (51), the amount of constriction accomplished by the staple is varied. An improved staple construction (61) of increased rigidity is also shown.

Abstract: A stapler apparatus which is provided with a needle feeding mechanism for feeding needles continuously formed in a band-like shape in succession to a driving-in station and which can prevent the band-like needles from moving backward and reliably feed the needles forwardly even if a backwardly moving force acts on the band-like needles in a state in which the leading needle is not bent.

Abstract: Obliquely cohered fasteners may be formed by adhering wires with an adhesive coating to form a strip. The strip is then shaped so that the wires are formed into fasteners of the desired shape. The adhesive coating is then plasticized and while plasticized, each fastener is offset from the next to obtain the obliquely cohered fasteners. Then, the adhesive coating is rehardened. Instead of applying a single adhesive coating, the wires may be adhered with a first thermoplastic coating and a second coating of a non-self-adhesive resin. The second coating may be applied only to that portion of the first coating covering the fasteners. Alternatively, as the fasteners are offset, the second coating may be cracked between fasteners to weaken the second coating, allowing the fasteners to be more easily separated when desired. The off-setting may be performed by a device which applies a force to one of the ends of the fasteners while the other of the ends of the fasteners are displaced.

A cover is pivoted to the frame between opened and closed positions and includes a curved peripheral wall and a pair of marginal side walls along the curved edges of the peripheral wall. A pair of transversely spaced locking elements are fixed with respect to the frame structure and the cover has locking surfaces adjacent the forward end portion thereof for engaging the locking elements to retain the cover in its closed position.

Abstract: A staple forming and driving tool (10) employing a vertical front portion of a staple head base (34), and sheath (40) to provide a space for the reciprocating former member (70) and a driver (80). A spring (50) urges base (34) and the sheath (40) together with spacer lugs (33) maintaining a defined distance between the base (34) and the sheath (40). A belt of staple blanks is fed through an opening (100) in the base (34) by a cartridge. The cartridge extends into the opening (100). A belt advancing means (104, 112) is provided which is held in an inoperative position by the forming tang (75) during a portion of the forming and driving stroke in order to prevent movement of a staple wire (200) during critical portions of the forming and driving stroke. The former (70) is moved during the forming and driving stroke through a path which permits former lugs (72) to guide the formed staple down to a point adjacent the workpiece.

Abstract: This relates to the production of folders such as those commonly used for binding loose sheets of paper into booklet form. There is provided a method and an apparatus for setting fastener elements, such as tangs and eyelets, into selected portions of a blank made of heavy paper or cardboard. The apparatus employs rotary die holding elements defining a nip or nips therebetween for receiving one or more portions of a paper blank, particularly a blank folded to a T-shaped configuration. The apparatus includes means for applying setting forces to the fastener elements during the very brief interval of time that the fastener elements are disposed in the nip or nips between the die holders. Radially movable dies are mounted in certain of the rotary holders and cam means are employed to apply momentary fastener element setting forces to the fasteners.

Abstract: A stapling machine is provided of the type which includes at least one stapling cylinder having a wire transport, a shaped disk which for the formation of the staples bites into a peripheral recess provided in the stapling cylinder, and a fixed staple guide which, with reference to the rotational direction of the stapling cylinder, is positioned after the shaped disk, projects into the peripheral recess and is underrun by the finished staple. The stapling machine is characterized in that the staple guide has, in the area of its surface which is underrun by the back of the staple, a post-bending edge which bites deeper into the recess in the stapling cylinder than does the outer periphery of the shaped disk.

Abstract: Detachably mounted on a sliding table are a plurality of part tape or belt feed units each of which intermittently feeds to a lead wire cutting station a part tape or belt holding a large number of parts of the same type, each of which has lead wires extended in opposite directions and coaxially of a main body of the part and attached adjacent to their ends to parallel strips of tape or belt in equidistantly spaced apart relationship with the lead wires of the adjacent parts. The sliding table moves in either direction so that the desired part tape or belt feed unit is moved to a part feed position at which the desired part tape or belt feed unit feeds the part to the cutting station. At the cutting station a cutter unit cuts off from the part tape or belt the lead wires of the part, thereby separating therefrom the part having lead wires of a predetermined length, and the lead wires are bent in the same direction.
