Beschreibung
Zusammenfassung:	A wire feeding mechanism (2) includes feeding rollers (21A, B) and a cushioning mechanism (25). The feeding rollers (21A, B) feed a wire (891), which is drawn from a wire supply source (28), along a predetermined feed path. The cushioning mechanism (25) is arranged between the wire supply source (28) and the feeding rollers (21A, B). The wire (891) has an intermediate portion that extends from the wire supply source (28) to the feeding rollers (21A, B). The cushioning mechanism (25) applies tension to the intermediate portion while the length of the intermediate portion is changing.
