Abstract: A spooling device for load straps comprising a spool, which at one end portion is freely rotatably supported and is formed as a projection and has a centrally passing axial bore for receiving an axle, at the end opposite the free outer end of the spool, the axle is drivingly connected to a manual crank, the spool formed with a V-shaped notch tapering radially towards the bore, and the axle provided with a radially directed, strip-shaped clamping jaw, whose free edge extends parallel to the axis of rotation of the axle/spool and forms the carrier of the axle, for affecting and rotating the spool, the surface of the clamping jaw of the axle, facing the direction of the rotation, and the opposite clamping jaw surface defining the spool notch, form a co-operating clamping surface pair by which the strap end is clamped and kept clamped during the entire spooling operating as long as the cranking is kept up.
