Abstract
The packing is made up of layers each of which is deformed into a zig-zag shape. Each layer has contiguous rows of deflecting surfaces which are interconnected by bridges and with every other deflecting surface being stamped out so as to be bent out of the plane of the layer. The stamped out deflecting surfaces of adjacent rows are offset from one another by the width of one deflecting surface and are bent out of so far as to be parallel to the next flank.
Claims13
A packing comprising a plurality of layers disposed one over the other, each said layer having a zig-zag shaped profile to define a plurality of flank planes with a plurality of contiguous transverse rows of pairs of deflecting surfaces and a plurality of bridges connecting said rows of deflecting elements to each other, each said deflecting surface of a respective row being disposed in angular relation to an adjacent deflecting surface of said row with every other deflecting surface of a row projecting from said flank planes in parallel relation to the adjacent flank plane whereby said layers define a structure of crossing deflecting surfaces.
A layer made of deformable material having a plurality of transverse rows of spaced apart bendable tabs defining an alternating sequence of integral deflecting surfaces and bendable deflecting surfaces and a plurality of bridges interconnecting said tabs in said transverse rows, said tabs being disposed in pairs in longitudinal rows of said sheet with said pairs of tabs being disposed in alternating manner with pairs of integral deflecting surfaces in said longitudinal rows.
A layer having a zig-zag shaped profile to define a plurality of flank planes with a plurality of contiguous transverse rows of pairs of deflecting surfaces and a plurality of bridges connecting said rows of deflecting elements to each other, each said deflecting surface of a respective row being disposed in angular relation to an adjacent deflecting surface of said row with every other deflecting surface of a row projecting from said flank planes in parallel relation to the adjacent flank plane.
A process for making a regular packing comprising the steps of
- forming a flat sheet with a plurality of transverse rows of spaced apart tabs to define an alternating sequence of integral deflecting surfaces and bendable deflecting surfaces;
- deforming the flat sheet to form a zig-zag shaped profile having a plurality of flank planes with two adjacent rows of said surfaces being disposed in a respective flank plane;
- and
- bending each tab of each row outwardly of said respective flank plane into parallel relation to an adjacent flank plane.
