摘要： A braiding machine of the maypole form having co-acting horngear assemblies positioned in a cylindrical housing and arranged to drive spool carriers along a double undulating and intersecting drive track groove as groups in opposed directions. The form of the groove is such as to avoid discontinuities both in normal and in tangential components of acceleration forces on the spool carriers. Drive is transmitted from the horngear assemblies to the spool carriers by drive forks each carried on a pivot shaft mounted for oscillating rotation through restricted arc on the respective horngear assembly. Oscillating rotation of the drive forks is effected by a cam follower arrangement engaging a cam track such that the drive forks propel the spool carriers along the guide track groove with constant or substantially constant linear velocity.
