<p>PURPOSE: To provide the finely controlled temperature distribution without irregularity to a part corresponding to a can body part of a blank of a metallic sheet on which the thermal transfer is achieved from a thermal transfer roll of a manufacturing equipment of the laminate metallic sheet for the can of body-bottom integrated type. CONSTITUTION: When a recessed part 3 of approximately equal shape to that of a can bottom part is formed on the position of the can bottom part of a thermal transfer roll 1, a number of small holes 11, 12 are provided before the lamination is made by a laminate roll after the thermal transfer in the prescribed part 8 except a part which is not blanked and a part where the recessed part 3 of a can body part 5 are connected so as to provide the shortest distance. The whole temperature distribution of the part corresponing to the can body part 5 of the metallic blank 4 can be accommodated within the prescribed temperature range. The blank 4 around the recessed parts 3 is cut out of the manufactured laminate metallic sheet, and this blank is pressed such as by the deep drawing to obtain the member for the can of body-bottom integrated type.</p> |
