Abstract
Layered sheets of food material are prepared by advancing a plurality of sheets of flexible food material on a moving conveyor belt beneath at least one substantially stationary spiral guide, each of which is positioned above the conveyor belt and plurality of sheets and each of which has a longitudinal axis substantially horizontal and at an oblique angle to the downstream direction of movement of the advancing belt and sheets. At least one of the advancing sheets is passed at least one complete turn about a spiral guide for guiding each sheet passed around each such spiral guide so that each guided sheet comes to lie above another sheet advancing on the conveyor belt to form layered sheets of food material.
