<p>A wire feeding system, for use with apparatus that processes the wire in conjunction with intermittent advancement of the wire, the feeding system operating to de-reel the wire and supply the de-reeled wire to the apparatus comprising; a first group of pulleys (20) and a second group of pulleys (21), and structure (27, 28, 32) mounting the groups so that the second group is movable relatively toward and away from the first group; first structure (34) for urging the second group of pulleys away from the first group of pulleys; wire drive structure to positively advance the wire to the apparatus; and the wire successively passing over pulleys in the groups, and successively between the groups, in passing from the reel to the drive structure; whereby the wire is maintained taut as the second group of pulleys moves toward and away from the first group of pulleys in response to intermittent operation of the drive structure; and second structure (37, 38, 39) for controlling the speed of the drive structure in response to sensing of the movement of the second group of pulleys. <IMAGE></p> |
