Abstract: A forming machine including a frame extending longitudinally on either side of a tool. This tool is arranged transversally to the central portion of the frame. Jaws arranged on either side of the tool, are each actuated by two pairs of quasi-horizontal jacks and quasi-vertical jacks. Each jaw comprises a point which is mobile in a vertical longitudinal plane, and this point is held in such plane by means of one of the control jacks of the jaw especially a quasi-vertical jack. This guiding jack includes pads arranged on the upper end of its roll and these pads slide on longitudinal vertical planes integral with the frame. The cradle of the jaw is hinged on the end of the rod of the guiding jack by means of an axis which is perpendicular to the axis of the jack whereof the axis is situated in the guiding plane.
Abstract: The hooking system of the lid (4) to the sliding plate comprises grooves (27) provided in the heating ceramic plate (11), to accommodate rails made of refractory steel.
These rails (26) enable on the one hand to fix the ceramic plate (11) below the metal plate (10), via tension rods (14) and, on the other hand, to hook the lid (4), using H-section parts (22) that nest into T-shaped grooves (25) of the said rails and in identical T-shaped grooves provided opposite to one another in the upper section of the lid (4).
