Abstract
A braiding bobbin includes a shaft and a spool from which a fiber thread can be drawn off through a thread guide mounted to rotate on the shaft. At least one torsion spring joins the shaft and the spool to each other. The spool is rotatable in a draw-off direction against the spring force and in an opposite, backwinding direction by the spring force of the torsion spring. A brake having an adjustable braking torque brakes rotation of the shaft in the draw-off direction.
