ARRANGEMENT FOR SPLICING PANELS TOGETHER TO FORM A CYLINDRICAL SCREEN
First Claim
1. A filter screen, comprising:
- a plurality of rods arranged parallel to one another in a first direction, the rods having first and second ends and first and second edges, the first ends of at least some of the rods adjoining the second ends of at least some of the rods to form joints;
a plurality of wires arranged parallel to one another in a second direction perpendicular to the first direction and attached to the first edges of the rods; and
a plurality of bars alternatingly welded between adjacent ones of the rods at the joints.

Abstract
Panels of a filter screen have a plurality of rods and a plurality of wires. The rods are arranged parallel to one another in a first direction. The wires are arranged parallel to one another and are attached in a perpendicular direction to the rods. The rods have jointed ends with a tab and a bevel along one edge of the panels and have flush ends along an opposite edge of the panels. The panels are connected together edge to edge in an elongated sheet by adjoining the jointed and the flush ends of the rods and then welding a plurality of splice bars alternatingly between adjacent ones of the rods at the joints. The elongated sheet is then rolled into a cylindrical tier that can be used as a portion of a basket, centerpipe or other cylindrical screen for a radial flow process or the like.
