<p>The wire-section dispensing unit (14) has an advancing device (28) for advancing the wire (18) stepwise. The two advancing wheels (110, 112) are driven intermittently via a four-bar mechanism (120) and a freewheel (114) in the direction of the arrow (E, E'). It is ensured by means of the wire guiding element (34) that the beginning of the wire (18) is reliably inserted in each case into the recess (42) of the receiving part (40). The groove-shaped recess (42) is open towards the bottom and, before a wire section (10) is cut off by means of the knife (38), is closed by a transfer part passing by the opening (44) of the recess (42).
