    • 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).

    • 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.

    • 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. After the first ejector rod displaces the formed head towards the control unit, the geometrical condition of the slot is determined by the slot detector (64). Thereafter the blank is displaced from the die by the second ejector rod.

    • 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). In an apparatus of making screws, rivets or similar objects the movable cropping bushing (24, 25) is secured to a transport device (15), by means of which it can be moved from a receiving position opposite the stationary bushing (14) to a discharge position opposite a die (16) between said die and a punch (27), which is adapted to move the blank (26) partly into the 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).
