The invention relates to a continuous annealer (1) for wire, for annealing and recrystalising a wire (12) in a continuous process. The continuous annealer (1) for wire comprises: two contact discs (2, 3) for contacting a first wire portion extending therebetween; an annealing zone (8) situated between the two contact discs (2, 3); and annealing means, in particular conductive or inductive annealing means, for annealing the first wire portion in the annealing zone (8), as a result of which a first partial recrystallisation process in the first wire portion takes place in the annealing zone (8). According to the invention, a recrystallisation zone (11) is situated downstream of the second contact disc (3), wherein, downstream of the annealing zone (8), the first wire portion passes through the recrystallisation zone (11) as the second wire portion, and a second partial recrystallisation process takes place in the second wire portion. The wire (12) is thus provided with the opportunity to recrystallise further after leaving the annealing zone (8) without further heating. By extending the recrystallisation time, the recrystallisation temperature can be reduced accordingly. As a result, the same degree of recrystallisation can be achieved overall with a significantly lower input of energy than when the wire (12) is cooled immediately after leaving the annealing zone (8).

DRAWING SHAFT AND DRAWING ROLLER FOR A WIRE DRAWING MACHINE
The invention relates to a drawing shaft (1) and a drawing roller (2) for a wire drawing machine, wherein the drawing shaft (1) has an external connecting means (3) and the drawing roller (2) has an axial bore (6) and an internal connecting means (4) arranged in the axial bore (6). The two connecting means (3, 4) are provided to form a form-fitting connection with one another, this occurring when the rotation axes (13, 14) of the drawing shaft (1) and the drawing roller (2) coincide and the external connecting means (3) of the drawing shaft engages in the internal connecting means (4) of the drawing roller (2). According to the invention, the external connecting means (3) of the drawing shaft (1) and the space, surrounded by the internal connecting means (4), in the axial bore (6) of the drawing roller (2) each have a convex, non-circular cross-sectional area (11, 12) perpendicularly to the rotation axis (13, 14) of the drawing shaft (1) and of the drawing roller (2), respectively, at at least one point. As a result of the convexity of the two cross-sectional areas (11, 12), the radial spacing between the radially innermost and the radially outermost point of the circumferential lines (9, 10) of each cross-sectional area (11, 12) can be designed to be very small. In this way, the form-fitting connection can also be used for a drawing roller (2) with a small wall thickness, without the wall of the drawing roller (2) being weakened too much.
