Abstract: A high speed braider, characterized in that the main shaft, driven by a prime motor, drives the rotating shafts of the inner and outboard spindle driving disks through a set of cylindrical gear transmission mechanism, the set of cylindrical gear transmission mechanism includes a main shaft gear and two translating gears, the main shaft gear engages with one of the cylindrical gears on the shaft of the inner or outboard spindle driving disks, and the two translating gears rotate together, of which, one engages with the cylindrical gear on the main shaft, another engages with the other of the cylindrical gears on the shafts of inner or outboard spindle disks, and the transmission ratio between the rotating shaft of inner spindle driving disk and the main shaft equals to the transmission ratio between the rotating shaft of outboard spindle driving disk and the main shaft.

Abstract: A rotary braiding machine interweaves strands to form a braid for a work piece, such as a hydraulic hose or the like. A frame has a central axis about which strands of fiber are braided. Inner bobbin-carrier assemblies and outer bobbin-carrier assemblies are carried circumferentially on the frame. The inner bobbin-carrier assemblies are rotatably supported by the frame radially outwardly of the central axis, are separated by recesses, and each supports a strand supply bobbin. Each of the inner bobbin-carrier assemblies has an inner tensioning and control assembly to pay-out a first strand of one or more fibers from its bobbin and to position the first strand in substantially perpendicular relation to the central axis of the frame. The outer bobbin-carrier assemblies are rotatably supported by the frame radially outwardly of the central axis and of the inner array of strand supply bobbins.
