Abstract
A flip-flow screener machine includes a carrier frame with primary, drive-induced vibration, to which a vibrating frame is coupled in a freely oscillating manner by means of elastic transmission elements and is excited and set to vibrate secondarily by the carrier frame via said transmission elements, transverse carriers being arranged on the carrier frame and on the vibrating frame, a transverse carrier on the vibrating frame lying downstream of a transverse carrier on said carrier frame, with a flexible screen bottom being arranged between two transverse carriers and detachably secured to said transverse carriers, each of the screen bottoms including at least one undercut portion by means of which they can engage behind an undercut on the transverse carrier, and two adjacent screen bottoms abutting one another directly at their front ends.
