Abstract
A device for forming a pointed wire tip on the ends of wires is provided. The device has receiving elements for receiving a wire, and heating device. The device stretches the wire causing the wire to taper and break resulting in the formation of a pointed wire tip at the point of breakage.
Claims20
Device for forming a pointed wire tip, characterized by
- a first means (12) for receiving the wire;
- at least one second means (14) for receiving the wire;
- at least one heating device which heats the wire in a section between said first receiving means (12) and said second receiving means (14);
- and
- at least one means which stretches the wire in the heated section according to pre-defined conditions in the direction of the longitudinal axis of the wire, wherein said stretching of the wire causes the wire to taper and break, thereby forming said pointed wire tip.
