摘要

1. Podnasadochnoe device with heater nozzle block comprising a horizontal layer composed of elements in the form of equalizing bars arranged on a horizontal layer of support elements in the form of lattices, the elements of each of said layers have through holes between mutually parallel surfaces of the horizontal elements, one of the layers through holes elements are flared upwardly, characterized in that the widening upwardly through holes formed in the layer elements expr vnivayuschih rings and through openings in elements in the form of a reference grating formed with vertical walls throughout the length of the hole or the same through holes made by expanding down the entire length of the hole, wherein the cross-sectional area of ​​the upper window of each through hole in the support members is equal to or greater than the area of ​​the lower cross-section of the through-hole corresponding leveling tiles. ! 2. Leveling device podnasadochnogo tile stove with a nozzle block having through holes between their surfaces parallel to each other, characterized in that each of said through holes are formed across an expanding aperture length in the direction of one of said parallel surfaces. ! 3. Podnasadochnoe device with heater nozzle block comprising a horizontal layer composed of elements in the form of equalizing bars arranged on a horizontal layer of support elements in the form of gratings, each element of said layers having through holes between the parallel
