Clamping band manufacturing machine and method of manufacturing clamping band

A clamping band manufacturing machine, comprising:

• a main machine part including:
• a band shaping stage for forming a clasp material into a U-shape, welding the U-shaped clasp on a band section made by cutting a long band-shaped material with a prescribed length, bending a mid portion of the band section in an arc by a guide rod, overlapping both end portions;
• a lever welding stage for welding a lever material and the overlapped portion of the band section and extending the lever material from the overlapped ends;
• an examination stage for measuring a length of an overlapped portion of the band section and the lever material;
• an arc shaping stage for bending the lever material in an arc by a fixed die and a shaping die;
• a circular shaping stage for expanding the bent portion of the band section so as to form the band section into a circular loop;
• and
• a conveying mechanism synchronously conveying the work piece including the band section to each of said sages, which are serially arranged, with machining action of each of said stages;
• and
• feeding mechanisms for feeding the band-shaped material, the clasp material and the lever material to said main machine part.
