Appiiatiba fii'a March-2 \My invention lrelates I'to braiding carriers,

and my main objectiisto enable the use of.

a loaded'bobbin of t-he maximum' diameter and capacity permittedby the requisite pass- 5 ing of they carriers in 'their intersecting paths. o ,this end the invention provides iiorthe avoidance of any` carrier parts which pro- -jeetv radially beyond the'` l'loaded bobbin, by iixedly mounting thelatter upon' a hollow axial ,standard fot-they carrier, and vby em-V ploying a lthread--tensioning `unit which Vis rotatably lmounted in Jsaid hollow standard .and intermittently rotated therein as .autolmatically controlled bythe tensioning ofthe bobbinfleaving thread -as `vfully set fforth :in connection Witlrthe accompanying drawings Iillustrating a preferred embodiment of the invention, the novel features-'of which are clearly'deiined inthe subjoined claims.

from theusualnbase portion 10 yof the carrier rises a central .e tubular standard' 11. Upon thisrigid standard is removably but non-rotatively mounted the bobbin 12; the tubular body of which` fits loosely thereon and is notched at its b'ase'lla so as to engage the correspondingly notched seat lll on the fixed standard 11, and the top of'vvliich is providedwvith a locking head 13 provided lwith paivlfengaging teeth as showngsaid bobbin thus becoming a iXed part of the standard When in operating position thereon. As indicated,thread material 12a is Wound directly upon the tubular bobbin to any lamount desired within the limit fixed by the 0 required free passing of cooperating carriers; there being no radially projecting carrier parts in my improved construction to otherwise limit the loaded diameters the iXedly mounted bobbins.
