Abstract
A screen assembly for a vibratory separator has been invented, which, in certain aspects, has a ridge-valley series of undulating screening material with a plurality of alternating ridges and valleys of screening material, each of said ridges having two spaced-apart ridge ends, a ridge top and a ridge bottom, and each ridge end with a portion of screening material that tapers down from its corresponding ridge's ridge top to a level of screening material at its corresponding ridge's ridge bottom.
