Abstract: Disclosed is a guiding device (100) for receiving an elongated metal object being propelled by a first propulsion means and guiding it towards a second propulsion means. The first propulsion means and the second propulsion means being configured to propel the elongated metal object along a longitudinal axis (101), wherein the guiding device (100) comprise guiding means for receiving the elongated metal object and guiding it towards the second propulsion means. The guiding means (100) have a shape configured to guide the elongated metal object to a predetermined position along a first axis (103), the first axis (103) being perpendicular to the longitudinal axis (102), wherein the predetermined position is determined by the shape of the guiding means (100).

Abstract: A clamping jaw assembly and cutter assembly employed in machinery used to manufacture nails, screws, rivets, and similar objects starting with wire material. The invention includes a groove design having a smooth wave that reduces the wear rate of the groove improving the life expectancy of the hard material clamping jaw insert. A clamping jaw assembly and cutting assembly that are both easily accessible for permitting quick replacement and/or indexing of the carbide-clamping inserts.

Abstract: A metal rod (20) having a conical or pyramidal cut extremity (20a) is used to make a mandrel for blind rivets. The rod is held in place between a pair of die segments (11) such that its end (26) of a preset length, including the tip protrudes from an upper surface (14) of the segments. Subsequently, a free intermediate portion of the swageable end (26) is axially compressed to form a mandrel head (27) by a punch (12) which has a lower face (17) parallel to the upper surface (14) of the segments with a conical or pyramidal recess (18) formed on the end. The free intermediate portion of the swageable end (26) swells radially outward to form the head (27) having a flat flange (31) from which the tip intrudes. The mandrel, which has the head formed uniformly without any eccentricity about the longitudinal axis of a mandrel body, can be produced inexpensively using a prior art nail manufacturing apparatus.
