Nails with offset heads are used in nail guns, where a strip of nails is used for shooting multiple times before reloading a new strip of nails.

Abstract: A nail machine and a tool ring for securing elongate bodies in the manufacture of heads on the elongate bodies. The tool ring has an axis of rotation, an outer circumference and a surface that extends substantially perpendicular to the axis fo rotation, and wherein the tool ring comprises a number of engagement devices spaced substantially equally at the circumference of the tool ring for receiving and releasably securing the elongate bodies. Each of the engagement devices has two mutually opposed holding jaws, at least one of which is movable and arranged on a movement mechanism so that it can be displaced towards and away from the opposed holding jaw. The engagement devices also have two opposed holding trays which are movable towards one another.

Abstract: A fitting for the tool ring in a nail machine, or a tool ring, said fitting having means for receiving and securing at least one holding jaw in the fitting, and a support face that enables the fitting to abut on a support face which is complementary to the support face of the fitting; and means for clamping the fitting onto the complementary support face; and wherein the fitting has at least one clamp face which is arranged opposite the support face; and wherein the means for clamping the fitting on the tool ring comprise a first element configured for abutment on the clamp face and past the support face and for engaging with an element on a tool ring included therefor.

Abstract: In a method of making a head on an elongate blank (26), the blank (26) is moved into a die (16) having a bottom stop (28) such that part of the blank (26) extends outside the die (16) end opposite the bottom stop (28). The protruding part of the blank (26) is engaged by a pre-upsetting bushing (25) positioned in extension of the die (16) and a punch (27) is slidably movable in the pre-upsetting bushing. The bushing (25) and the die (16) are moved away from each other during the latter part of the deforming procedure. The movement of both the punch (27) and the bushing (25) with respect to the die (16) is positively controlled so that the bushing (25) and the die (16) are moved away from each other at the latter part of the deforming procedure, while the punch (27) continues to press against the blank in a direction toward the die (16).

Abstract: In a method of making an elongate object (49) with a head at one end and a point at the other end, a blank (49) is placed in a die (50) having a through-going channel, following which the head end is subjected to axial pressure by a tool (52), while a stop member (55) is kept engaged with the die (50) at its other end. A pre-formed head is initially provided on the blank (49) so that the head has an excess of material with respect to the size of the final head. A cavity (56) is formed in the stop member and is in extension of the through channel. When blank (49) is subjected to axial pressure the tool (52) causes flow of material in the shank of the blank (49) so that blank material flows into the cavity (56) of the stop member.

Abstract: A method of ejecting an elongate blank (57) from a through bore in a die (58) in which one end of the blank (57) has been formed with a head by a tool. Ejector rods (60, 62) are successively moved into the die (58) against the other end of the blank. A first ejector rod (60), short with respect to the length of the die (58), moves the blank (57) a relatively short distance, and then the blank (57) is completely ejected using ejector rod (62) having substantially the same length as the die (58). A control unit (63) is placed in facing relation to the formed head of the elongate blank at a predetermined distance from the formed head. The control unit determines whether the formed head conforms to a predetermined geometrical condition thereof, specifically by forming the control unit with a slot detector (64) having the same shape as a slot formed in the head.

Abstract: In a method of making screws, rivets or similar objects from a metal wire (6) the wire (6) is moved through a stationary cropping bushing (14) forwardly to a movable cropping bushing (24) present in a receiving position, following which the movable cropping bushing (24) is moved away from the receiving position substantially transversely to the axial direction of the wire to release a blank from the wire (6). The movable cropping bushing (24, 25) is then moved together with the released blank (26) further on to a discharge position, in which a punch (27) is adapted to move the blank (26) partly into a die (16) and to compress the blank (26) sufficiently to pre-upset it by cold flowing in the region between the die (16) and the movable cropping bushing (25).
