PURPOSE:To eliminate the protruding of a paste, by forming turning up ribs at both sides and at the proper positions in the middle of an expanding grid body, at the thickness larger than that of the grid body and suitable to maintain the paste. CONSTITUTION:At both sides and at the proper positions in the middle of a grid body 1 made by expand-processing a sheet of copper or a copper alloy, ribs 2, 2' and 2'' turning up to the front aud to the back sides to form in the thickness thicker than the grid body 1 and suitable to maintain a paste are furnished respectively. Thereby, it is made possible to have an enough thickness when the paste is filled, by utilizing the ribs 2, 2' and 2', to make it easy to fill the paste and to improve further the adhesion of the paste to the grid body 1. Moreover, by forming the turning up parts at the both sides, the paste will not be protruded from the grid 1. |
