Abstract (en)

[origin: EP3539686A1] A Machine for producing a portion of a mould comprises a bolster arrangement (140) a flask (121) and an upper compacting system (110). The bolster arrangement (140) comprises a bolster frame (144) and a bolster plate (141). A pattern (131) is positioned on the bolster plate (141) in the bolster frame (144). The bolster frame (144) is positioned on a machine table (172) and the bolster plate (141) is positioned on a stroke device (171). The pattern (131) and the upper compacting system (110) are movable towards each other by a movement of the bolster plate (141) and the bolster frame (144) relative to each other
