A braiding apparatus for braiding the perforated braid with constant intervals of perforation forms a first braid section to braid one strand with a plurality of yarns, sequential braid section to braid a certain length of braid with two strands and another sequential braid section to braid a final strand with the previous strands. The braiding apparatus equips a carrier guide plate (10) which has a pair of core yarn holes (12, 12null), two tracks of carrier contours (14, 14null) and a plurality of coupling holes (13, 13null), a base plate (40) disposed underneath the carrier guide plate (10), a plurality of carriers (20), feed gears (30) rotatably mounted on the base plate (40), feed discs (31) which are fixed on top of feed gear shafts (32), a pair of carrier contour changers (50, 50null), actuators (42, 42null) mounted underneath the base plate (40) for repetitively crossing and separating operations. Thus, various kinds of braids with constant intervals of perforations can be produced by using a differing number of core yarns and carriers.
