摘要： PURPOSE:To make it possible to wind a tape of wide width with a uniform thickness and high accuracy, by dividing delivery filaments to be delivered to a mandrel through a dividing section, collecting them through a gap of an axial symmetry body and rotating the axial symmetry body to an angle which is vertical to a specified winding angle when the filaments are wound on the mandrel. CONSTITUTION:Semi-spherical cone 6 having a rigid circular cylinder on its small diameter side is et on both ends of a mandrel 5. When filaments to be wound on the mandrel is going in the right direction, at the time when the axial symmetry body (i.e. the point of filament delivery) reaches A1 above the end point of the left cone, the axial symmetry body is rotated to an angle (+theta deg.) where the axial symmetry body is vertical to a specified winding angle and the axial symmetry body is moved through points A2 and L2 while this condition is being kept. Then, it is turned in the left direction and at the time when the axial symmetry body reaches A2 above the end point of the right cone, the axial symmetry body is rotated in the opposite direction as much as the above described angle and is moved through points A1 and L1 while (-theta deg.) is being kept and reaches the point A1 in the right direction. The filament winding is carried out by repeating this procedure.
