  • Pipe producing apparatus and existing pipe rehabilitating method employing the same
    Patent number: 8347477
    Abstract: In an embodiment, a shaping frame (2) of a pipe producing apparatus (1) includes a plurality of linking bodies (20) in which a pair of linking elements (21, 22) are rotatably coupled via a coupling shaft (23), a bending link (30) with opposite ends of which coupling elements are rotatably coupled via coupling shafts (23) and which expands or contracts the shaping frame (2), a drive unit (40) with opposite ends of which coupling elements (25, 25) are rotatably coupled via coupling shafts (23) and which forcedly sends out a profile strip (100) from the inside, and a joint unit (80) with opposite ends of which coupling elements (21, 22) are rotatably coupled via coupling shafts (23) and which is provided at a joint portion (120) of a winding of the profile strip.
