Patent ID: 6907810

Claim:
A braiding apparatus for braiding a perforated braid comprises: a carrier guide plate ( 10 ) providing a pair of core yarn holes ( 12 , 12 ′) at each center of each left half and right half thereof, a plurality of coupling holes ( 13 , 13 ′) formed in radial direction around circumference of each core yarn hole ( 12 , 12 ′) on said carrier guide plate ( 10 ), two tracks of carrier contours ( 14 , 14 ′) formed in circular zigzag patterns with a certain depth along the circumferential coupling holes ( 13 , 13 ′), said two tracks of carrier contours ( 14 , 14 ′) forming inner and outer paths around said coupling holes ( 13 , 13 ′) to cross each other, four square slots ( 15 , 15 ′) perpendicularly arranged each other to form a cross center on time two tracks of the carrier contours ( 14 , 14 ′) at a center of said carrier guide plate ( 10 ), a plurality of carriers ( 20 ) installed on said carrier contours ( 14 , 14 ′) for rotating and traveling along said carrier contours ( 14 , 14 ′), a base plate ( 40 ) disposed underneath said carrier guide plate ( 10 ) at a certain distance, a plurality of feed gears ( 30 ) rotatably mounted on said base plate ( 40 ), a number of said feed gears ( 30 ) being equal to the number of said carriers ( 20 ), a plurality of feed discs ( 31 ) fixed on top of feed gear shafts ( 32 ), and said feed discs ( 31 ) interposed into carrier bases ( 21 ) located at the lower part of said carriers ( 20 ), a pair of carrier contour changers ( 50 , 50 ′) mounted underneath said carrier guide plate ( 10 ) and inserted into the four square slots ( 15 , 15 ′) for operationally providing alternate tracks of said carrier contours ( 14 , 14 ′) to cross and separate the carriers ( 20 ) at the cross center of said carrier contours ( 14 , 14 ′), and a pair of actuators ( 42 , 42 ′) mounted underneath said base plate ( 40 ) connected to said carrier contour changers ( 50 , 50 ′) through an operating rod ( 41 ), a linkage ( 43 ) and a change rod ( 51 ), for repeatedly performing the crossing and separating operations.
