    • A series of individual single tooth thread cutting tools are rotated concurrently about the axis of a pipe and are applied in cutting relation thereto in succession, at the same starting point, by movement radially of the pipe in a time delay relation to each other. They are maintained in cutting relation concurrently until they advance near to the end of the portion to be threaded. They are then retracted from the pipe in succession in the same order in which they were engaged with the pipe, in the same time delay relation to each other, all at the same location endwise of the pipe and substantially the same location circumferentially of the pipe.
    • 一系列单个单根螺纹切削工具绕管的轴线同时旋转,并且在相同的起始点处以相互间的延时关系沿着管道径向移动而连续地与其相切地施加切割关系。 它们同时保持切割关系,直到它们靠近待螺纹部分的末端前进。 然后,它们以与管道接合的相同顺序连续地从管道中缩回,并且在相同的时间相互延迟的关系中,全部位于管道的相同位置处,并且管道的周向基本相同的位置 。
