Binding machine

A binding machine, comprising:

• a pair of feed gears configured to feed a plurality of wires;
• a curl forming portion comprising a curl guide and a leading guide, the curl forming portion configured to constitute a looped feeding path for winding the plurality of wires fed by the pair of feed gears around a binding object;
• and
• a binding portion comprising a wire locking body and a sleeve, the binding portion configured to twist the plurality of wires wound around the binding object, wherein
• the curl guide is configured to curl the plurality of wires fed by the pair of feed gears,
• the leading guide is configured to lead the plurality of wires curled by the curl guide to the binding portion,
• the curl guide includes:
• a first wire guide configured to regulate a position of at least one of the plurality of wires toward an outer peripheral side in a radial direction of the looped feeding path along a circumferential direction of the looped feeding path;
• a second wire guide configured to regulate the position of the at least one of the plurality of wires toward one side in an axial direction of the looped feeding path along the circumferential direction, and having a second guide surface protruding inward along the radial direction from the first wire guide;
• a third wire guide configured to regulate the position of the at least one of the plurality of wires toward another side in the axial direction along the circumferential direction, and having a third guide surface protruding inward along the radial direction from the first wire guide;
• a parallel guide portion provided on a downstream side of the curl guide with respect to a feeding direction of the wires;
• and
• a parallel orientation leading portion provided on an upstream side of the curl guide with respect to the feeding direction of the wires, and having a radial dimension larger than that of the parallel guide portion,
• the parallel orientation leading portion includes a delivery portion provided on an upstream side with respect to the feeding direction of the wires and inclined in the axial direction with respect to the radial direction of the looped feeding path and extending in the feeding direction of the wires, and
• the curl guide is configured to allow the plurality of wires to pass therethrough while being arranged in the radial direction of the looped feeding path.
