Abstract (en)

[origin: FR2767494A1] The machine has two spools delivering interlocking strips of material, mounted on a driven rotary circular cage (8). The cage turns about a horizontal axis coinciding with the lengthwise axis of the tubular structure being wound, the structure being formed at a laying point close to the rear face of the cage. The two spools are mounted so they rotate together with the cage, the front face of which carries at least one linear tensioner (31, 31') for the strip material, located between the spool and laying point. The front face of the cage also carries rollers (34) which guide and bend the strips, between the spools and laying point.
