る仕上げ成形を行うものである。 In the figure, 11 is a cylindrical body, and 13 is a forming spatula. The cylindrical body 11 is made of aluminum and is rotated about an axis by an appropriate rotation means (not shown). Further, the forming spatula 13 is made of steel,
A curved pressure molded part 17 on the base 15 and a protruding ironing protrusion 19 connected to this pressure molded part 17.
are integrally formed. The forming spatula 13 is moved in the direction of the arrow (A→B→C→D→A in FIG. 1) by appropriate means (not shown). The pressure forming part 17 of the forming spatula 13 is for performing preforming in this invention, and the ironing protrusion 19 is for performing finishing forming in this invention.

断により行われる。 In the method of the present invention, first, the pressure molding part 17 of the molding spatula 13 is pressed against the rotating cylindrical body 11. Then, as shown in FIG. 2, the end portion of the cylindrical body 11 is preformed along the curved shape of the pressure forming part 17 of the forming spatula 13. At this time, the end of the cylindrical body 11 is not completely closed yet. Then, in this state,
As shown in FIG. 3, the squeezing protrusion 19 is moved close to the axis of rotation of the cylindrical body (corresponding to "shigo" in the present invention), closing the end of the cylindrical body 11 and squeezing the convex portion 21. Form outward. Furthermore, the ironing protrusion 19 of the forming spatula 13
The squeeze convex portion 21 is cut by passing the rotation axis of the cylinder (see Fig. 4), and the cylindrical body 1 is cut.
1 is finished molded (at this time, the molding spatula 13 is at position C in FIG. 1). In addition,
Since the forming spatula 13 is fixed while the cylindrical body 11 is rotating, frictional heat is generated at the contact area between the two 11 and 13, and as a result, such cutting is performed by fusing.
円筒体１１の仕上げ成形終了後は、成形用へら
１３は回転軸芯方向に離れ（第１図におけるＣ→
Ｄ→Ａ）て元の状態に戻る。 After the finish forming of the cylindrical body 11 is completed, the forming spatula 13 is separated in the direction of the rotational axis (C → in FIG. 1).
