Abstract: Device for making a thread reserve on coil tubes for textile spools, having a coil frame for exchangeably holding the coil tubes while being rotated at an operating speed in a given direction, a take-up coil, and a winding cylinder, comprising friction wheel means driveable by the winding cylinder against the surface of a coil tube for rotating the coil tube for a short time at initial winding of the take-up coil at a speed lower than the operating speed, and means for driving the winding cylinder at a speed lower than the operating speed in a direction opposite the given direction while the thread reserve is being made.
