In one embodiment, an article of footwear includes a first braided layer and a second braided layer. The first braided layer passes along an upper surface of a midsole while the second braided layer passes along a lower surface of the midsole. In another embodiment, an article of footwear includes a first braided layer and a second braided layer. The first braided layer passes along an upper surface of a plate while the second braided layer passes along a lower surface of the plate. The plate includes a plurality of apertures. The plurality of apertures are configured to receive ground engaging members. In another embodiment, an article of footwear includes a unitary braided component that includes a first layer and a second layer.

A braiding apparatus includes a platform, a base plate, a core unit, a transmission unit, a track assembly, and strand carriers. The track assembly is divided into two braiding track groups each provided with transmission discs. The transmission discs of both braiding track groups are sequentially connected to define two braiding routes. The strand carriers shuttle on both braiding routes respectively and incessantly. Two intersection points are defined when the two braiding routes intersect. Accordingly, carrier strands fed by the strand carriers are wound around a core strand fed by the core unit while shuttling incessantly and are interwoven with each other while passing through the two intersection points during the incessant shuttling motion, thereby wrapping a multi-convolutional braided layer around the core strand to complete a rope. Each convolution of the braided layer has two crossing points, which increases the practicability of the rope.

A method of manufacturing a braided footwear upper is provided. The method includes braiding a two-layer, single-tube structure with a first end that couples a first braided layer to a second braided layer, and second end that couples the first braided layer to the second braided layer of the tubular braided structure. The first end is proximate the second end. At least one yarn from the first end, and at least one yarn from the second end are braided with at least one draw yarn. The draw yarn is braided to be easily removable, such that the first end is selectively de-coupled from the second end. When the draw yarn is removed, the double-layer tubular braided structure is expandable to form a larger diameter tubular braided structure.

A medical balloon with a variable diameter that is reinforced with continuous fibers woven to form a fabric with a varying number of layers and fiber densities. Portions of the balloon having a relatively smaller diameter are reinforced with a fabric having a reduced fiber density and an increased number of layers to facilitate the placement of the layers. The fabric also includes a braiding pattern that facilitates the transition from a single layer fabric to a multiple layer fabric. Also described is a manufacturing method for the braiding and layering.
