Abstract

Improvements in the object of the patent 338,816, by method for the manufacture of bodies of light specific weight, based on foam material, particularly heat insulating bodies of own strength and relatively high stability, according to claim 1 of the main patent, characterized because of at least partial replacement of the solid matter powder that is mixed with the mass of rounded grains of foam material after having wetted the surface thereof with liquid binder mass and hardenable to coat the binder coating layers of the grains, fibrous material of an average fiber length of 1 to 4 times greater than the average diameter of the grains of foam material is used, in order to increase the tensile strength of the hollow cell structure produced in a mold after the hardening of the binder by pressing the loose mass of grains of material rounded and double coated foam that has been obtained.
