Abstract

1,229,944. Making hollow-ware. M. LACHAUSSEE, and A. MAIGRET. 29 Aug., 1968 [15 Sept., 1967], No. 41285/68. Heading B3A. A method of making metal articles, e.g. basins 3a or cupels, from blanks 3 located in rows in echelon in a metal strip comprises forming the blanks by cutting the strip only along portions 4 of the peripheries of the articles so that the blanks remain attached to spacing webs 6 of the strip by elements 5 which retain the blanks as the strip is advanced through means for stamping the articles to shape. Circular or star-shaped holes 2a, 2b, 2c are formed before the cuts 4 so as to separate the webs 6, and more than two rows of blanks may be formed of circular or other shape. The strip is fed in steps under a series of tools for effecting various operations. After forming the slots 4, the blanks undergo various stamping operations to form the basins 3a, which result in expansion of the slots 4 into crescents 8 and half-crescents 7.
