. ABSTRACT OF THE DISCLOSURE A simple method employing liquid spraying means is described for preventing the partial breakdown of the edges and side walls of shaped mats composed of substantially dry discrete resin coated particles during their emergence from the depositing means and their transportation into the hot press for consolidation. The mats are usually several inches thick so that many of the dry particles from the sides along the top edges of the mat invariably cascade down the sides because of vibration of the caul, or carrier, during trans- portation. Consequently, in order to insure that all the edges of the pressed board are solid after the board is trimmed to the desired size, the width and length of the deposited mat have to be substantially increased. By spray- ing a liquid along the edges of the mat immediately after its deposition of the particles, sufficient integrity is thereby imparted to the edges to hold the particles in place during transportation to the press and thus allow the size of the deposited mat and therefore the width of the trimmings and waste of material to be substantially reduced.
