Wire-working apparatus including an electric motor machine which draws, i.e., sizes linear stock, such as, rod stock, bar stock, wire stock, etc., as it is advanced or fed to be operated upon intermittedly in a discretely driven fabricating machine, for example, a header or a cut-off machine located a short distance away. The machine for drawing the stock has a reciprocable die which is spring-biased in the nonworking direction and is intermittedly advanced along the stock in the stock working direction by a power-actuated movable member having a predetermined stroke and with respect to which the die is relatively movable, a movable stop for limiting movement of the die in the nonworking direction the position of which stop is changed as a function of the slack in the stock between the two machines, an automatic wire grip assembly at the fabricating machine side of the die, selectively operable power means for rendering the grip assembly inoperative to grip the stock and/or selectively operable power means to prevent return of the die and thus discontinue the advancing of the stock through the die.
