摘要： A corrugated pipe manufacturing apparatus provided with a roller assembly consisting of a plurality of rollers rotatable at an equal speed and having a plurality of projecting rings respectively, each of which rollers forming a generally helical body due to the projecting rings and constituting a substantially one rotary shaft, and a synthetic resin supply unit for feeding synthetic resin strips to the roller assembly, characterized in that the pitch, diameter and width of the projecting rings are reduced gradually in accordance with the coefficient of contraction of the synthetic resin strips, driven rings which can be rotated in accordance with peripheral speed of the outer edge portions of the projecting rings being provided in the roller valley portions between the projecting rings. Owing to such construction, the separation of the synthetic resin strips, which is ascribed to the contracting actions thereof, from the rollers and the vertical wrinkles (strain regarding the interior of the strips) which are liable to occur between the projecting rings and the valley portions can be prevented, and corrugated pipes having excellent molding stability, a high precision and a high durability can be manufactured.

摘要： A welded state monitoring device and method for monitoring on-line the state of an electric-resistance welded pipe, such as the welded state, or the butted state, more correctly than conventional. A mirror (23) provided at a one-end portion in a case (21) receives light emitted from a welded portion (5) of a cylindrical steel sheet (1) sideways through heat-resistance glass (22) to project the image of the welded portion (5) toward a relay lens (24) provided to the root-end portion in a relay lens unit (13). The relay lens (24) transmits the image of the welded portion (5) to a converter lens (12), and the converter lens (12) forms the image onto the imaging surface of a CCD camera (11). Therefore, the welded portion (5) can be imaged sideways with a resolution corresponding to the resolution of the CCD camera (11), and information on the welded portion (5) can be collected on-line more correctly than conventional.
摘要翻译：一种焊接状态监测装置和方法，用于比传统方式更正确地监测诸如焊接状态或对接状态的电阻焊接管的状态的在线状态。设置在壳体（21）的一端部的反射镜（23）将从圆筒形钢板（1）的焊接部（5）射出的光通过耐热玻璃（22）侧向射出，从而将所述焊接部分（5）朝向设置在中继透镜单元（13）中的根端部分的中继透镜（24）。中继透镜（24）将焊接部分（5）的图像传送到转换器透镜（12），并且转换器透镜（12）将图像形成在CCD照相机（11）的成像表面上。因此，能够以与CCD摄像机（11）的分辨率对应的分辨率向侧面成像焊接部（5），并且可以更正确地收集关于焊接部（5）的信息。
