Braiding machine with continuous tension filament control

Abstract From the Canadian patent

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 …
