ABSTRACT:
Apparatus for laying-up fine filaments, i.e. filaments which may be readily broken by bending, tension or torsion stresses, which comprises a rotatable platform carrying a plurality of filament bobbins, each bobbin being supported on the platform so that it can rotate about its own axis and about an axis perpendicular thereto, a drive system for rotating the bobbins about the latter axis as the platform is rotated to produce one rotation of each bobbin about the latter axis with each revolution of the platform, braking means for the bobbins which varies the braking force in accordance with radius of a filament winding on a bobbin, tubular guides extending between each bobbin and the laying-up point and supporting discs intermediate the bobbins and the laying-up point which are rotatable with the platform, the tubular guides being rotatably supported on the discs.
