A needle element (14) is provided in the at least one channel (9a, 60). The needle element can be displaced lengthwise inside the channel (9a), using a drive device (27). According to the invention, the needle element (14) is combined with a screw spindle (13) that is screwed into a nut (16). The screw spindle (13) or the nut (16) can be rotationally driven by a drive device (27) so that the needle element (14) can be displaced in an axially defined manner in relation to the die cavity (1a) at will. |
