The smooth tube (45) is corrugated by means of a corrugation plate (43) located in a corrugation head (42) which can be driven rotationally. The corrugation head (42) is driven directly by a hollow shaft motor (37, 38).Type: GrantFiled: January 16, 2001Date of Patent: June 18, 2002Assignee: NexansInventors: Christian Frohne, Ernst Hoffmann, Wolfram Klebl, Dieter Muller

Publication number: 20010032870Abstract: The clamping band manufacturing machine is capable of full-automatically manufacturing the clamping bands and highly increasing the manufacturing efficiency. The machine comprises a main machine part and parts feeding mechanisms. In the main machine part, a band shaping stage welds a clasp on a band section, bends the band section in an arc, and overlaps both end portions of the band section. A lever welding stage welds a lever and the overlapped portion of the band section. An examination stage measures a length of an overlapped portion of the band section and the lever material. An arc shaping stage bends the lever in an arc. A circular shaping stage expands the bent portion of the band section. A conveying mechanism synchronously conveying the band section to each of the sages, which are serially arranged. The feeding mechanisms feed the parts, e.g., the clasp, to the main machine part.Type: ApplicationFiled: April 12, 2001Publication date: October 25, 2001Applicant: Kabushiki Kaisha MihamaInventor: Takeshi Nakamura
