Abstract
A machine and method for layering sheets of food material has a conveyor belt for conveying a plurality of sheets of flexible food material lying flat and parallel to one another on the conveyor belt and at least one substantially stationary spiral guide positioned above the conveyor belt. Each spiral guide has a longitudinal axis which is substantially horizontal and at an oblique angle to a downstream direction of flow of the sheets of food material on the conveyor belt and is positioned to enable a sheet of the flexible food material to pass beneath it and then to be guided at least one complete turn around it so that the guided sheet comes to lie above another sheet advancing downstream on the conveyor belt.
