Abstract

Improvements introduced in the object of the main patent No. 255,438, that is, in a production process of asbestos and cement articles configured by filtering an aqueous mixture comprising asbestos fibers and hydraulic cement dispersed in water, starting from an aqueous suspension to form on a conveyor a sheet or sheet of said subdivided material, and using a flocculating agent as indicated in patent No. 255,438, which are characterized in that the dispersion of the flocculating agent is controlled so that the agent is dispersed in the suspension in certain predetermined places to regulate the relative thickness of sections of the sheet of material subdivided into particles, across the width of the conveyor.
