ABSTRACT:
A machine for braiding filaments around a common axis including: two coaxial annular arrays of filament bobbins; there are filament guides for the radially outer array which alternately move their filaments radially inwardly of and then radially outwardly of the alternate ones of the radially inner array of bobbins; the motion of the filament guides is coordinated with the positions of the inner array of bobbins; one embodiment of the improvement relates to the filaments from the outer array of bobbins being maintained at a constant tension, without tensioning compensation means being required, as the filament guides shift the filaments from the outer array alternately radially inwardly and radially outwardly of the radially inner array of bobbins; in the other embodiment, the support for the braiding machine carries deflectors for deflecting the outer array bobbin filaments radially inwardly or outwardly, and the deflectors are adjustably positionable around the periphery of the inner bobbin array for enabling the deflectors to be used for rotations of the bobbin arrays in reverse directions.
