The invention concerns a braid structure comprising a plurality of braided layers of stranded material in which the layers are laid down in a single pass of a braiding machine, with at least one strand of each layer extending into a contiguous layer to form an interlock between the layers. The invention also concerns a machine and a method of making the structure by supplying groups of strands, (R, B, G, O, W), to a braid forming station, whereby each group of strands forms a braid layer. A strand (R) from one of the groups passes into or through the strands (B) of a group of an adjacent layer to form an interlock therebetween.

Apparatus for making a braid structure

A solid braid structure comprising a plurality of interlocked layers is created by causing a plurality of package carriers of yarn to move along a plurality of defined serpentine paths by track modules. The track modules extend in a first direction to define a longitudinally extending path corresponding to a first layer of the braid structure and in a second direction to provide at least one crossover path between adjacent serpentine paths. The package carriers which move in the first direction create a first layer of braid and, at a crossover path, move between adjacent serpentine paths to cause the yarn forming the first layer of braid to interlock with the braid of an adjacent layer.
