Abstract

Improved apparatus for treating flat sheets, especially leathers, spatially bending, stretching and pressing alternately in both directions of the direction which is normal to the sheet feeding plane, consisting of at least one unit of support and pressure cylinders which are provided with mutually overlapping treatment elements, characterized in that the treatment elements are arranged in the rings that are aligned next to each other in the support cylinder and in the pressure cylinder of the unit, the adjacent rings always being angularly displaced between yes in the middle of the passage of the treatment elements.
