In such a known two-for-one twisting spindle (DE-PS 23 17 D53 and 23 kZ ZBk) the rotating body is a porous solid body with capillary action. It consists of porous sintered metal or a porous sintered plastic. In both cases, spherical particles are sintered in such a way that small spaces remain between them which are connected to one another. However, it was found that such sintered materials for
