摘要：
A wire-feeding mechanism comprises a rotatably mounted pulley formed on its edge with a continuous circumferential groove and plural rollers arranged to hold an endless flexible belt against a segment of the edge of the pulley. The belt thus is adapted to hold the wire in the groove as one roller is driven.
