Abstract

This invention concerns a continuous manufacturing process of sections ( ) or plates from soft matter ( ) which is extruded under heat and encased by at least one strip sheet ( ), said encased matter subsequently being calendered, shaped to the desired profile and finally cut into lengths, process which is particularly remarkable in that the matter used is a mixture containing a non-synthetic binder and water, so that the mixture becomes sticky by undergoing said heat treatment in an aqueous medium, which assures adhesion of the casing onto the matter during calendering, while the product undergoes at least one drying operation after said calendering operation. The binder is advantageously starch-based and the mixture may also contain a plasticizer, for example containing urea. The invention also concerns an installation for implementation of the process and the products thus obtained.
