The tension head of a strand carrier for a braiding machine comprises coaxial members, the first of which is fixed and the second of which is axially displaceable toward the first member, and a plurality of tension spring cartridges therebetween biasing the second member away from the first member. The spring cartridges are removable without disassembly of the fixed and movable members and each cartridge includes a spring guide supporting a compression spring in a precompressed condition in which the spring has a length considerably shorter than its uncompressed length. When the cartridge is in place, the spring is adapted to be further compressed from its precompressed length to bias the second member away from the first member. The carrier further includes a bobbin coaxial with the first and second members and a clutch arrangement including a clutch plate interposed between the bobbin and the second member of the carrier, and a plurality of clutch spring units interposed between the first member of the tension head and the clutch plate to bias the latter toward the bobbin. Each of the clutch spring units includes a compression spring releasably compressed in place by a corresponding retaining member mounted on the first carrier member. The carrier includes a support shaft on which the bobbin, tension head and strand guide components are releasably mounted by a latch arrangement between the shaft and tension head.
