A tape winding apparatus including a base member which revolves around a body around which a tape is wound such as a coil conductor used in a large-size rotary machine and advances or retreats in the axial direction of the revolution; first supporting means for a wound tape which is attached to the base member and can deliver the free end of the tape; a second support which is pivotally mounted about an axis to the base member by means of a pivot and is rotatable substantially normal to the rotational direction of the base member; a first roller projecting from the base member in the advancing or rewinding direction of the base member so that the peripheral surface of the first roller is close to or contacts the axial line of the axis thereof; and a second roller which is mounted to project from the second support and be separated from the first roller so that a given portion of the peripheral surface of the second roller is constantly positioned on or close to the axial line of the pivot, wherein the free end of the wound tape to be supported by the supporting means is wound around the body successively through the first and second rollers.
