Abstract: A stitching method and a wire stitcher having a stitching head for stitching sheet-like materials using annular-eyelet staples, includes a staple support with a supporting body in the stitching head. The staple support supports a region of the annular eyelet during a driving-in operation and is moved out of the annular eyelet only when legs of the staple passing through the sheet-like material, have been largely bent over.

Abstract: A pneumatically operated stapler that has a single selectively operable adjuster operatively associated with a staple leg diverter. The single selectively operable adjuster is constructed and arranged to be adjusted within a range of leg deflecting positions to affect the lateral movement of the staple leg diverter. The different leg deflective positions effects an amount to which the diverter will deflect the legs of the driven staple during a drive stroke. A single operation of the single selectively operable adjuster both moves the adjuster and retains the adjuster in an adjusted position within the range of leg deflecting positions.

Abstract: A forming plate and a driver plate are held at a front portion of a path of supplying connected staples in a laminated state. A staple in a C-shape formed at an inside of a strike out path formed between a front end face of a supply path and a back face of the face plate arranged on a front side of the supply path is pressed to supply to inside of the strike out path toward the face plate by a pusher urged by a spring. The staple is struck out by the driver plate. The pusher is made to constitute a first pusher, and a second pusher for pressing a leg portion of the staple to the face plate is aligned to be arranged to a side of a staple strike out port of the first pusher.

Abstract: A stapler both forms and drivers staples from connected staple blanks retained in a magazine. The stapler includes a driver and a former. The former eliminates jams caused by the last staple in a magazine becoming rotated prior to being formed and struck by having the capability of simultaneously forming a staple being struck and the staple blank connected to the staple being stuck.

Abstract: A pneumatically operated stapler that has a single selectively operable adjusting mechanism that is constructed and arranged to be adjusted within a range of leg deflecting positions is disclosed. The stapler includes a staple leg diverting member that is carried by a portable structure for lateral movement into and out of a drive track. Successively driven staples are driven with a selected leg deflection between a minimum deflection and a maximum deflection. The adjusting mechanism is selectively adjusted within the range of positions to adjust the amount of bias of a biasing structure acting on the leg diverting member.

Abstract: A stitching apparatus for manufacturing stitching wire staples, in particular annular eyelet staples, for stitching stacked sheet materials, includes a stitching head basic body having a driver for driving the stitching wire staples into the stacked sheet materials in a downward movement of the driver. A former shapes the stitching wire staples, in particular annular eyelet staples. The former is pivoted away during the downward movement of the driver. A wire clamping lever is mounted pivotably in the former. The wire clamping lever has a control element which runs on a control cam in such a way that the former is supported as a result in the upward movement of the driver, with the result that the former is pivoted-in in the upward movement to a different point than the pivoting-out of the former in the downward movement.

Abstract: The invention proposes a staple-forming apparatus which is intended for stapling machines for forming staples and may be designed to be smaller than priorart apparatuses. This is achieved according to the invention in that a locking bar (9) for locking a pusher in the forming apparatus during the operation of forming the staple is fitted in a moveable manner in the pusher and a fixed stop (13) for the locking bar (9) is provided on the housing (2) of the staple-forming apparatus.

Abstract: A stapler attachment for use with an electromechanical device driver comprises a staple holding member which is spring mounted to a staple closing member, which is, in turn, mounted to a threaded driver element concentrically mounted about a threaded shaft such that staple closing member and the staple holding member can be advanced and retracted along a track within a housing. A staple is advanced by the rotation of the threaded shaft until the staple holding member is stopped against an opening lip formed in an opening at the distal staple discharging end of the housing. At this position, the prongs of the staple have been advanced out of the distal staple discharging end and into the tissue to be joined. The staple closing member continues to advance as the spring between the staple holding member and the staple closing member compresses. This advancement permits the staple closing member to deform the staple into a closed D-shape conformation.

Abstract: A staple wire cutting element (4) is mounted displaceably on a stapling device (1) in which staple wire segments are shaped into a staple and driven into a sheet stack. A control lever (8) that is in engagement with a radial cam unit (6) engages the cutting element (4). The radial cam unit (6) is driven via an overrunning clutch (10), one end of which has a gear (11) which is fixed to the radial cam unit (6) and engages into a gear (5b) of a stepping motor (5). The other end of the overrunning clutch (10) has a gear (12) which is fixed to a transport wheel (13) for staple wire transport. A gear (27), which is mounted displaceably along its rotation axis and is mounted rotatably about the same rotation axis as the gear (5a), engages into the gear (12). The gears (5b, 27) are equipped at their sides facing one another with tooth sets (28).

Abstract: So that a staple driver does not perform a movement relative to a staple holder until the staple holder comes down on the material to be stapled, provision is made according to the invention for the staple holder and the staple driver of a stapling head to be driven by a common drive device via a cam control mechanism. The cam control mechanism has a cam plate which is made to perform a stroke movement via a drive pin on which it is rotatably mounted. The staple holder and staple driver are driven by two connecting rods which relative to the rotation axis act eccentrically on two sides on the cam plate. A stationary guide rail, against which the cam plate is supported with a guide surface during a first phase of the working stroke, prevents a rotary movement of the cam plate during the first phase of the working stroke and thereby fixes the staple driver relative to the staple holder.

Abstract: A transport table reciprocates between a collator, at which it receives a stack of loose sheets, and a stapling head for stapling the sheets together. Cam followers on the table engage cam surfaces during the reciprocating table movement to cause jogging movements of end and side retaining means to jog the loose sheets into a neat stack. The stack is delivered into a gap between the stapling head and an anvil, and the stapling head moves through a first half cycle, forming a staple and clamping the stack. A gate on the transport table lifts to free the stack while the table retracts, and then the stapling head drives the staple through the stack. The gate lowers when the transport table returns to its original position.

Abstract: A magazine fed, trigger driven surgical stapler to close a surgical incision. The stapler has an anvil and a staple driving die, an adjustable stop for controlling movement of the staple driving die so that staples can be reformed to a range of closed positions. The anvil is pivotable under control of the staple driving die between a staple engaging position and position clear of the staples. A forcep assembly operable under actuation control of the staple driving die acts to draw the edges of the incision into close approximation. A staple blank with a concave back, upper arms extending the concave shape of the back and pointed lower arms extending downwardly and inwardly from the upper arms, which blank on reformation around the anvil will adopt a substantially hexagonal configuration.

Abstract: A chain link type stapler operates in transit at about 45,000 items per minute to staple and crease printed paper products. Only two link chains are required and they have a common contiguous path for receiving and clasping the paper products for transit while being stapled by means of mating, stapler and anvil links. The stapler link operates to receive wire lengths, form staples therefrom, insert and clinch the staples over a cyclic path of the chain. This is achievable by means of a reciprocating wire clip assembly journalled in an internal cavity of the stapler link. Reciprocation is programmed by a cam arm extending externally from the clip assembly and stapler link on which roller means is mounted to ride in a cam track about the chain travel path.

Abstract: A "loop"-type wire stitching machine head includes a reciprocating drive coupled to a staple-forming and driving means and to a wire feed means for feeding a length of staple wire to a holder and severing it. A bender forms the wire over the holder into a generally inverted U-shaped staple. A supporter with a rounded projection is then inserted between the legs of the staple and a drive bar deforms the bight portion of the staple over the projection into a curved loop portion and then drives the formed loop staple into an associated workpiece, retracting the supporter in the process. The supporter is biased to its supporting position and a guide plate guides its movement to that position. A cam positively holds the supporter in its supporting position during forming of the loop portion of the staple and effects positive movement thereof partway to its retracted position after formation of the loop portion to accommodate driving of the staple.

Abstract: A surgical instrument comprises an elongated body having a working zone at a distal end thereof. Kinematically connected between themselves and disposed within the body are: a mechanism for feeding wire into the working zone of the body, a mechanism for forming U-shaped staples from the wire, and a mechanism for reshaping U-shaped staples into rectangular ones, provided with a driver and anvils. The driver is connected with a reciprocating drive along the longitudinal axis of the body and is provided with a working portion in the form of two V-shaped projections. The anvil is disposed in the working zone of the body perpendicularly to its longitudinal axis in a plane of motion of the driver so that it can be moved out of this plane. The length of the anvil is less than the transverse side of the U-shaped staple.

Abstract: A wire stitcher in which a piece of wire is cut from a supply of wire W fed to a stitcher head and formed and driven through a set of sheets to bind the sheets together. The wire is guided into position relative to the driver and former by a guide mechanism arranged in the path of the former and which is resiliently mounted so as to be displaced by the former during forming.
