METHOD FOR PRODUCING PANELS CONSISTING OF AN EXPANDED RENEWABLE MATERIAL, AND ASSOCIATED DEVICE

摘要

The invention relates to a method for making panels of an expanded renewable material, essentially starch, characterised in that it comprises the successive following steps: extruding unit members or strings having a small section and a substantial length L; assembling by juxtaposing and gluing these strings thus obtained along their longitudinal axis in order to produce a layer having a width A; superimposing and assembling by gluing at least two of said string layers in order to produce a block having a height B and a length L, said block thus exhibiting a section with a side A and a side B having dimensions related to the number of assembled unit members; and cutting said block transversally relative to the longitudinal axis along a length l in order to obtain plates having a maximal section of A x B with a selected thickness l. The invention also relates to a related device.
