Abstract
L'invenzione riguarda un metodo ed un dispositivo per la sformatura di sottili piastre grezze, di calcestruzzo o di agglomerato di pietre naturali, o simili, stampate per compressione in una pressa per piastre. L'invenzione propone di lasciare, all'atto dell'apertura dello stampo, che le sottili piastre grezze s'inflettano, staccandosi pertanto più facilmente dal fondo dello stampo, dopo di che vengono deformate per mezzo di una ventosa aspirante disposta in una campana di espulsione e portate di nuovo indietro alla loro posizione distesa di partenza, mentre vengono tenute e stabilizzate per mezzo della ventosa aspirante all'atto dell'operazione di espulsione fino al loro deposito su un carrello portapiastre, o simili.The invention relates to a method and a device for the demoulding of thin raw plates, of concrete or of agglomerate of natural stones, or the like, molded by compression in a plate press. The invention proposes to allow, upon opening the mold, that the thin raw plates become inflected, thus detaching themselves more easily from the bottom of the mold, after which they are deformed by means of a suction cup arranged in a bell of expulsion and brought back to their relaxed starting position, while they are held and stabilized by means of the suction cup at the time of the expulsion operation until they are deposited on a plate-holder trolley, or the like.
