PROBLEM TO BE SOLVED: To form a lamp assembly of a conductive sheet with a hole to accept a bulb. SOLUTION: A strip cut out of a sheet 40 has a main part 60, an end part 66 bent in parallel to the sheet 40 in the condition that it matches a hole 42 but is ranging over 180 deg. to be apart therefrom and a middle part 62 to connect the end part 66 of the strip to the main part 60. The adjacent ends of folding lines 68, 70 are mutually isolated in parallel to the folding lines 68, 79. In this way, a press tool punch is moved perpendicular to the main part 60 of the strip to bend the strip 60 along the second folding line 70. |
