Claim Text:
1. A method of manufacturing a solder column, the method comprising: a first step of conveying a solder wire from an insert opening into a main body section and toward a discharge opening of the main body section, from which the solder wire inserted into the insert opening is discharged and projecting the solder wire from the discharge opening; a second step of cutting the solder wire projected from the discharge opening with a first cutting blade and cutting the solder wire inserted into the insert opening with a second cutting blade wherein each of the first and second cutting blades is a single edge blade in which a parallel surface is in parallel with a direction in which each blade extends an inclined surface is at a predetermined angle to the parallel surface, and the inclined surface of the first cutting blade is inclined in an opposite direction to the inclined surface of the second cutting blade, the second step also including sliding the parallel surface of the first cutting blade against the discharge opening and sliding the parallel surface of the second cutting blade against the insert opening and cutting the wire with said parallel surfaces in contact against outer surfaces of the main body section; and further comprising a step of cutting an end of the solder wire to be inserted into the insert opening with a third cutting blade; and wherein the solder wire is supported between the insert opening and the discharge opening and the solder wire is not supported between the second and third cutting blades.
