Abstract
An open meshwork, hollow cylindrical roll which may be up to thirty feet in axial length and up to sixteen feet in outside diameter has alternate axially-extending, straight and undulated strips of thin material supported in radial grooves in a pair of opposite end rings. The straight strips are imperforate, planar and of substantial width, and the undulated strips are narrow and comprise an inner strip extending between the lower portions and an outer strip extending between the outer portions of each pair of adjacent straight strips. The undulations are V-shaped with at least half of each apex cut away for welding.
Claims11
A roll comprising
- a pair of shaft-supported, end rings each having an inner peripheral face with a plurality of radial grooves spaced therearound and
- an elongated hollow cylindrical grid-like shell said shell having:
- a plurality of straight, wide, thin, planar, strips, each extending axially of said roll, each opposite end of alternate straight strips being seated in one of the radial grooves in said end rings and said strips having inner, intermediate and outer portions,
- and a plurality of pairs of undulated, narrow, thin strips, one strip of each pair extending axially of said roll between the opposite inner portions of each adjacent pair of said straight strips, the other strip of each pair extending axially of said roll between the opposite outer portions of each said adjacent pair of said straight strips, and the intermediate portions of said straight strips being free of any undulated strips,
- said undulated strips having V-shaped undulations with sharp apex portions, each said apex portion being cut away for at least half its width and said undulated strips being interconnected with said straight strips at said sharp, cut away, apex portions to form triangular shaped open mesh therewith.
A foraminous roll of the type having a pair of end rings with a hollow cylindrical, open mesh, grid extending therearound, the grid being formed by alternate, axially extending, straight and undulated strips characterized by
- the straight strips being of predetermined width,
- the undulated strips being of predetermined lesser width and arranged in pairs, one undulated strip of each pair extending between the inner portions of each pair of straight strips, and the other undulated strip of each pair extending between the outer portions of each said pair of straight strips and the intermediate portions of each pair of straight strips being free of obstructions to flow and free of any undulated strips,
- the undulations in said strips being V-shaped with sharp apices, the sharp apices thereof being welded to the adjacent straight strips.
