<p>The manufacture of plastics products, in particular of board-like articles from scrap or salvaged plastics materials, results by providing a mat of the raw material in particulate form, heating the mat to the softening point of the material by conveying it through an oven (4). After that the mat is compressed between three rollers (10, 2, 8) arranged generally one above the other by being passed between the top and middle rollers (10, 2), then between the middle and lower rollers (2, 8), and then around the lower roller (8) to continue in the direction away from the oven, the middle and lower rollers being of substantially greater diameter than the upper roller (10).</p> |
