Experimantal apparatus for deep-dralwing of rectangular, chiefly square shell of about 100mm width, was made, and effects of shape of blank and dimensions of tools were studied about aluminium plates mainly of 1 mm thickness. Results are as follows : 1) Fairly rounded corner shape of blank is the best to avoid unevenness of edge, and octagonal shape is permissible when corner radius of shell r_1 is larger, but square shape is unsuitable. Corner radius of blank R_0 is desirable to be (5～10)% larger than Rc calculated, assuming the surface area is constant. 2) Maximum drawing force Pm relates linearly to (R_0/r_1) when l_1, r_1, r_d remained constant, and also relates linearly to (R_0h_c)/r_1・(l_1-2r_1) practically. Braking force is nearly estimated from the tensile strength of the blank material when r_1 is about 20mm, but is nearly the half when r_1 is smaller. 3) The limits of drawing expressed by (R_0/r_1)_<lim> just before tearing go up to 6, and 8～10 by (h_c/r_1)_<lim>. They are larger when r_1 is smaller and l_1, l_2 are larger, and relate to (l_1/r_1) nearly linearly. 4) Distribution of strains at the corner denote the similar tendencies with drawing of cylindrical shell.
