WIRE KNOTTING MACHINE ABSTRACT A machine operable to twist the end portion of a cross wire around a longitudinal wire disposed at right angles to the cross wire, and then to twist the cross wire end portion about the standing portion of the cross wire, to form a "knot". The machine consists of a knotter die rotatable about the axis of the longitudinal wire to form the first twist, and to force the end por- tion of the cross wire operatively against an anvil configurated to form the second twist so that both twists are formed in a single operation, although the two twists lie in substantially right angled planes. This substantially doubles the speed at which the knots may be formed in automatic machinery. As optional equip- ment, other dies may be added for pressing the wire bend formed in the second twist, and the raw end of the cross wire, closely adjacent the longitudinal wire, so that the raw wire ends are shielded. This knot "finisher" operation is performed at a station different from that at which the knot is initially formed, so that in an automatic machine, the finishing operation does not reduce the production rate.
