PURPOSE:To efficiently cover a unit cell by inserting a unit cell into the opening of a flat heat shrinkable tube piece, and shrinking the tube by heating to closely cover the unit cell. CONSTITUTION:A pair of upper and lower creases and a pair of right and left creases are press-formed in the lengthy direction of a rolled flat shrinkable tube 1, and the tube 1 is cut in a specified size at either one of creases to form a flat tube piece b. The tube b is bent along a pair of creases positioned at both side ends to open it so as to have a rhombic cross section. A unit cell d is inserted into the opening c of the tube b, and the unit cell d is transferred to a heater 38. The tube b is shrunk to closely cover the outside of the unit cell. By this process, the unit cell is efficiently covered with the resin film. |
