Core insertion plant, using several conveyors arranged in a closed, horizontal rectangle along which work cylinders push carriers. On work cylinder pulls a row of cores out of a core making machine onto the carriers, which then travel to the insertion station, where a suction box lifts the cores off the carriers. The suction box is fitted with a vacuum pipe, and can be raised and lowered by a WC fitted on a trolley, which is reciprocated horizontally along rails so tha cores can be moved outside the rectangle and lowered onto moulding boxed on another conveyor track. Each carrier is pref. fitted with a plate carrying a row of cores. Fully automatic insertion of sand cores in moulds is effected, using no manual labour.
