Embodiment Construction

[0031] figure 1 The corrugation (plate) 1 shown in side view is a thin metal plate bent to form regular corrugations. The repeating profile of the corrugation (plate) 1 is zigzag with curved sides 9, with upper 6 and lower 7 peaks with the smallest possible radii.

[0032] The elevations 3 and depressions 5 are formed at least in the slope of the corrugation. The protrusions and depressions are of the same shape so that a protrusion 3 viewed from one side (face) of the strip becomes a depression when viewed from the other side (face) of the strip.

[0033] The corrugated (plate) 1 is made by simple bending and stamping of a thin flat (flat) metal strip with a device A comprising two opposing die blocks, namely a lower die block 11 and an upper die block 12, The lower mold block 11 and the upper mold block 12 are alternately moved towards and away from each other.

[0034] Each mold block has two teeth projecting towards the other mold block, which are indicated by reference...

Abstract

According to the method of the invention, folding and stamping a strip is carried out through consecutive steps by means of two opposite work rest blades (11, 12) that move alternately towards and away from each other, said work rest blades having textured active surfaces (11, 12) that are not combined with the two surfaces of the wave, and the surface of the strip (17) is textured before carrying out the folding and stamping. The invention can be used for air distillation columns.

Description

technical field [0001] The present invention relates to a method for the manufacture of structured corrugated packing from perforated or non-perforated strip sheet material, the overall surface of which is mechanically textured (texturée), and essentially Formed by moving a repeated (profiled) profile parallel to the edge of the strip along a line with a main orientation, which line is inclined relative to the edge of the strip and which may or may not be straight for at least part of its length. [0002] The invention also relates to corrugated packing produced by this method. Background technique [0003] Cross corrugated packing is used in different equipment - including mixers for single phase only and devices for heat exchange and / or mass transfer between two fluids. A special application is distillation, especially atmospheric distillation. [0004] The packing consists of several modules or "laminations", each of which is formed from a stack of strips corrugated obl...
