PURPOSE: A tube winding device is provided to operate a winding spindle in the whole operational revolving speed range with a large revolving speed spread by arranging a bearing device for supporting a clamping chuck on a spindle support, and allowing the bearing device to cooperate with the clamping chuck in the region of a support end section. CONSTITUTION: Two winding spindles(2,3) are protruded and rotatably supported on a spindle support. The winding spindle(2) has a rotatable clamping chuck(18) to clamp a plurality of wound tubes(14) in sequence. The clamping chuck(18) of the winding spindle(2) has a support free end section(19) at the supported end section of the winding spindle(2). A bearing device(21) cooperating with the clamping chuck(18) is fitted to the spindle support concentrically around the support free end section(19). A bearing base(22) is arranged on a support end section(20) on the opposite side of the clamping chuck(18) at an interval with the end face of the winding spindle(2). The bearing base(22) is connected to the clamping chuck(18) via a pin(23) by shape coupling.
