摘要： A die (1) for mounting in an associated die holder (20) for the production of heads on elongate bodies such as nails or screws. The die has a body (2) with a top surface (3) provided with a through-going groove (4) for receiving and holding an elongate body longitudinally in said groove. Furthermore, the die has a recess (5) on one side merging into the groove (4) at one end of the groove (4) suitable for forming the head of a nail or screw. The die has a side surface portion, e.g. conical, shaped for press fit by contact with a corresponding inner surface portion of a bore or hole (30) in the associated die holder. Further, a second side surface portion (9), e.g. a plane portion, of the die serves to engage with a corresponding inner surface portion of the bore or hole of the die holder. Hereby, it is ensured, that angular orientation of the groove (4) is fixed relative to the die holder (20), and it has been proven that the two different side surface portions of the die, e.g. with a conical portion and a plane portion, provides an efficient press fit which ensures a long lifetime of the die. Further, the die is very simple to mount in the die holder, e.g. by hand, and it is simple to eject by a tool. Thus, altogether a highly efficient nail production can be obtained with such die and die holder system.

摘要： A die holder mounts a die to form heads on nails or screws. A top surface of the die includes a groove for longitudinally receiving and holding an elongate body. The die has a recess merging into the groove at one end of the groove to form a nail or screw head. The die is conical for press fit by contact with an inner surface of a bore or hole in the die holder. A top surface of the die is planar to a top surface of the die holder with a bottom surface engaging bottom part of the die holder. The bottom portion of the die has a recess or engaging with a corresponding protrusion die holder fixing an angular orientation of the groove relative to the die holder. Two opposite dies are brought together by two opposite die holders forming the head.

摘要： A machine for the mass production of flechettes consisting of a plurality of in-line units, each unit including outer and inner coaxial tubes. The outer tube being rotatable while the inner one is stationary. Axially spaced, spring loaded, radially slidable dies are carried by the inner tube and the outer tube is provided with similarly arranged cam lobes which force the dies inwardly and simultaneously or sequentially upon rotation of the outer tube to perform fin shaping, pointing and cutoff operations on a wire which is fed axially through the inner tube. All units are rotated by ring gears on the outer tubes and a single driven gear.
