TAPE WINDER

An increased-diameter curved-surface part 6 that holds a roll tape 1 at the distal end of an arm 3 coupled with a turning shaft 4 secured to a rotating body 5, and that contacts the arm 3 turning during rotation, is provided. Within an angular range in which the arm 3 contacts the increased-diameter curved-surface part 6, the arm 3 is pressed in a rotationally outward direction while rotating, whereby the tape is wound on an object 9 while the tape stretched from the roll tape 1 to the object 9 is drawn out. In an angular range in which the arm 3 does not contact the increased-diameter curved-surface part 6, the tape that was drawn out first from the roll tape 1 is wound while being taken up by the object 9, without drawing out the tape. Repeating these operations in an alternating manner suppresses displacement from the rotational center axis of the object and results in suitable winding being carried out. 提供了直径增大的弯曲表面部分6，该直径增大的弯曲表面部分在臂3的远端处保持卷筒胶带1，臂与固定到旋转体5的转动轴4联接，并且该直径增大的弯曲表面部分与在旋转期间转动的臂3接触。在臂3与直径增大的弯曲表面部分
