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: A staple-forming and inserting apparatus 10 is provided having an apparatus 22 for movement of the cutter box 20 to allow automatic variations in staple length for one or more staple-forming and inserting apparatus 10 said staple-forming and inserting apparatus 10 being provided with a staple crown 105 supporting shoe 56 to permit supported insertion of the staple into the workpiece the device 10 having blades 50a, 50b for pinch-cutting of the staple wire 72 to provide chisel ends to legs 101 of stable 100 device 10 have key and rail construction to allow the operating drive 16 and bender 18 rails to travel on keys 32 that may be replaced to avoid wear on drive 16 and bender 18 rails and replacement of the rails and a floating bender rail 18 that prevents overstrike and damage to knives 50a, 50b.

Abstract: A device for connecting products composed of stacked and continuously conveyed webs or sheets of paper or the like, wherein the webs or sheets are connected by a wire-like stapling material which can be cut and deformed into individual clamps. The stapling device includes a supply roll with conveying unit for the stapling material, a cutting device for cutting the stapling material to a length required for forming the clamps, a clamp forming unit, a plunger for pushing the formed clamps into the product and a clamp closing unit. The supply roll with the conveying unit, the cutting device and the plunger of the stapling device are mounted on a rotatable drum-shaped body which approximately contacts the product on one side thereof transversely of the conveying direction.

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: An apparatus for attaching a plurality of studs on a flexible sheet material such as work fabric, leather or the like according to a desired pattern comprizes a holder for holding the sheet material, a supply device for supplying studs severally, a plastic working device including a punch and die set for attaching the studs on the sheet material, and a drive device for varying the relative position between the holder and the plastic working device. The studs may be supplied severally and attached sequentially to the sheet material while the relative position between the holder and the plastic working device is varied by the drive device.

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.
