A plurality of clamp devices are mounted on the frame and spaced along the length thereof for holding the wire. A plurality of drive devices are operatively connected respectively to the clamp devices to move them into and out of an operative position in a path of travel of the carriage where the clamp devices engage the wire. A plurality of position sensors are operatively connected respectively to the drive devices and sense the approaching of the carriage toward the respective clamp devices disposed adjacent thereto to produce a sensing signal in response to which each drive devices is operated to move the clamp device associated therewith out of its operative position.
