    • A generally planar fabric for forming into cylindrical reinforcing cages for concrete pipe includes a set of wire strands for forming the longitudinal wires of the cage, a first set of transverse strands for forming the cage circumferentials welded onto one side of the longitudinal defining strands, and a second set of transverse wire strands for forming cage circumferentials welded on the other side of the longitudinal defining strands. Each of the second set strands is preferably but not necessarily, in line with a corresponding first set strand on the opposite side of the longitudinal defining strands. This fabric is formed into a cylindrical cage, and in one embodiment, the inside circumferential strands are narrower in diameter than their corresponding outside circumferential strands.
    • 用于形成用于混凝土管的圆柱形加强保持架的大体平面织物包括一组用于形成保持架的纵向线的线材线,用于形成焊接在纵向限定线束的一侧上的保持架圆周的第一组横向线束,以及 用于形成保持器周向焊接在纵向限定线束的另一侧上的第二组横向线股线。 每个第二组股线优选但不一定与在纵向限定丝线的相对侧上的对应的第一组股线一致。 该织物形成为圆柱形保持架,在一个实施例中,内周向股线的直径比其对应的外周股线窄。
