    摘要: A method and apparatus for vulcanizing tires are provided. An unvulcanized tire is transferred and loaded onto a lower mold member when a plurality of arcuate sector mold members aligned along the peripheral direction locate at the radially outermost positions as well as upper ends of the sector mold members incline radially outwards about their lower ends. An upper mold member moves toward the lower mold member while the sector mold members are swung about their lower ends to straightly stand the sector mold members, and the sector mold members are then synchronously displaced radially inwards, so that the unvulcanized tire is hermetically enclosed in a mold space formed by these mold members. The unvulcanized tire is vulcanized within the mold space to give a vulcanized tire. The sector mold members are synchronously displaced radially outwards, and swung such that the upper ends incline radially outwards about the lower ends while the upper mold member is moved away from the lower mold member, so as to remove the vulcanized tire out of the mold.

    摘要: The fracture-free paving block (1) comprises a cement block substrate (1-1) and a top solid layer (1-2), and is characterized in that the top layer is selected from a cured cement mortar layer and a tile-like layer firmly bonded to the substrate with cement mortar; the top layer is bonded to the block substrate with lateral margins (2) of 1 to 8 mm wide in horizontal distance (1.sub.5) from the peripheral edges of the substrate: and the vertical distance (1.sub.6) from the surface of the top layer to the peripheral edge of the substrate is 5 to 50 mm. The method for producing the paving block (1) having a tile-like top layer comprises applying adhesive cement mortar between the back of the top layer (1-2) and the upper surface of the substrate (1-1); placing the top layer on the substrate with the above-mentioned margins (2) of the substrate surface: and applying vibration and/or pressurization between the top layer and the substrate.
