摘要

A process for the manufacture of corrugated or ribbed or plain, straight or curved sheets of asbestos cement from the plastic state of a known preliminary preparation, according to which the corrugation or rib is effected by means of an inverter-stacker complex, in the wherein the undulation occurs with the help of an aspiration on the underside of the sheet and the sheets are stacked alternately or not with rigid molds, characterized in that said corrugator-stacker group is substantially constituted, in order, by the fresh sheet that it is necessary to undulate, by the corrugating device, by a mixed stack of corrugated sheets and molds, by rigid corrugated molds; said stations presenting above a mobile trolley between two positions carrying three suction lifting devices, of which the first one takes out the fresh flat sheet to be undulated and takes it to the second station on the corrugating device; the second one takes out the corrugated sheet from said device and carries it over the mixed pile of the third station; the third, working in phase opposition with the second, removes the molds from the fourth station and carries them over the mixed pile of the third station; and in that said inverter-stacker group is strictly coupled with the ends of a closed circuit of travel, of suitable length and of any conformation, and preferably with conditioned air, temperature and humidity, which is resorted by the mixed piles with the sheets fresh wavy alternating with the molds until the hardening and the first consolidation of the sheets have been completed.
