<p>Reinforced sheet(s) are placed in one section of the open mold (1) by a manipulator including pressing units (6a, 6b, 7). Th push the sheets (4) against the surfaces of the mold section, first in one location, then another, whilst preventing displacemen the first location. The mold is closed and the product is subsequently extracted. An Independent claim is included for the gripping system employed. Claims also cover: the assembly applying the sheets agai the mold; and the corresponding line of manufacturing equipment. Preferred features: The location(s) pressed correspond to edge( or the central zone of the reinforced sheet(s). Pressing units comprise actuators with rigid pressing blocks mounted upon them. block alternatively includes sections parted by intervening, inflatable inserts which cause best conformation against the mold shape. The grips include needles parallel to the direction of mold closure, mounted on the same support as the pressing units. T needles undergo lateral displacement for mold conformation, occurring as the sheets are located in it. Pre-shaping is undertaken The plane of mold separation is vertical. Grips are carried by a manipulator arm. A grip is pulled towards the first mold sectio to press the sheets against it using a frame moving with respect to it. The sheet(s) are molded-over, against the first molding surface, by introduction of complementary plastic to fill the cavity. This plastic is introduced into the open mold first, or el is injected into the closed mold.</p> |
