Claim 15

The screen of claim 11 wherein at least one of the channels of the panel is formed with a substantially planar bottom surface between two ridges and has at least one of the plurality of openings formed in the bottom surface.

Claim 16

The screen of claim 11 wherein the panel includes two substantially planar and side surfaces forming a ridge having a substantially triangular cross-section, each of the two flat sides of the panel having defined therein at least one of the plurality of openings.

Claim 17

The screen of claim 11 wherein the first and second webs of wire mesh are tensioned across each one of the plurality of openings.

Claim 18

The screen of claim 15 wherein the first and second webs of wire mesh are tensioned across each screen cell by heating the first and second webs of wire mesh prior to bonding with the support panel.

Claim 19

The screen of claim 11 further including a third web of relatively coarse wire mesh immediately adjacent and underlying to the second web mesh for supporting the first and second webs of wire mesh.

Claim 20

The screen of claim 11 in combination with a shaker for separating solid particles from a fluid flow.

Claim 21

The combination of claim 18 wherein the screen is supported on the shaker such that the ridges are oriented in a direction that is substantially parallel to the direction of the fluid flow.

Claim 22

A screen for a shaker comprising: a first web of wire mesh; a second web of wire mesh immediately adjacent to the first web of wire mesh, the first and second webs of wire mesh cooperating to prevent particles having a dimension greater than selected size from passing through the screen; and a relatively rigid support panel including a series of alternating parallel ridges and channels lying in substantially a horizontal plane when attached to a shaker and to which is bonded the first web and the second web to create a complementary series of alternating ridges and channels of wire mesh; wherein, the panel includes a plurality of openings, the first and second webs of wire mesh being bonded to the panel around each one of the plurality of openings to form a plurality of screen cells within the screen, each screen cell being thereby independently supported by the panel; each of the ridges in the panel including two flat sides forming a substantially triangular shape, each of the two flat sides having defined therein at least one of the plurality of openings; and each of the channels includes a substantially flat, horizontal bottom surface between two ridges and the bottom surface includes at least one of the plurality of openings is formed therein.
