Device forming flat objects of adjustable thickness depositing a fluid substance on a support

摘要

Thin flat objects or cakes are made from a fluid substance spread over a surface in the required shape. The fluid material is fed to the spreader from a hollow shaft (8) positioned axially through a circular drum (1). The drum has an opening (4) in its wall, the shape and size of the desired product. Material passes from the shaft (8) through a radial spreader (17) which is in contact with the inner surface of the drum. As the drum rotates the spreader is sealed until it reaches the opening when a layer of fluid material is spread onto the surface below (23), the same shape as the drum's opening, and the same thickness as its wall Manufacture of any thin product from a liquid material, such as pancakes or thin biscuits. It can also be used to produce filter discs or refractory material discs from a ceramic material. Photo sensitive coatings can also be prepared. High production rate of regularly shaped products can be achieved.
