Abstract
A machine wherein wire is being withdrawn from a reel or barrel by a wire comb forming unit which draws the wire at a given frequency has a lever which is pivoted at such frequency by a rotary cam and carries a first roller. The lever is pivotable about the axis of a second roller and the wire is trained first over the second roller and thereupon around the first roller on its way toward the wire comb forming unit. The pivoting lever ensures that the wire is drawn from the reel or barrel at a constant speed in spite of intermittent consumption of wire in the wire comb forming unit. The diameters of the two rollers are the same.
