    • A process and apparatus for producing a dry-pressed molding from a particulate or granular molding material such as a ceramic molding composition in which the composition is initially drawn into a loading cavity by applying a vacuum thereto. The loading cavity is formed by a first mold half and a shooting head having a molding surface the shape of which determines the shape of a premolding which is formed upon entry of the composition into the loading cavity and sufficiently compressed to retain its shape after the shooting head has been removed to allow a second mold half to be positioned over the first mold half. The shape of the part of the premolding formed by the shooting head molding surface differs from that of the second mold half in such a way that, on final pressing, the compression starts in the areas of relatively greater thickness of the premolding before it starts in the areas of relatively smaller thickness so that the compression ratio is maintained approximately constant over the whole of the area of the molding.
    • 一种用于从颗粒或颗粒模制材料(例如陶瓷模制组合物)生产干压模制品的方法和装置,其中组合物最初通过向其施加真空而被抽吸到装载腔中。 装载空腔由第一半模和具有成型表面的成型表面形成,成型表面的形状决定了在组合物进入装载腔中时形成的预制件的形状,并且在拍摄之后充分压缩以保持其形状 头部被移除以允许第二半模定位在第一半模上。 由拍摄头成型面形成的预成型部分的形状不同于第二半模的形状,使得在最终压制时,压缩开始于在其开始之前预成型件的较大厚度的区域 厚度相对较小的区域,使得压缩比在整个模制区域保持近似恒定。

    • An apparatus for firing ceramic shaped products, particularly porcelian tableware, comprising a kiln provided with a through tunnel and a heating device, grid-like pallets for holding the shaped products during their passage through the through tunnel, feed means for feeding the unfired shaped products onto the pallets, and discharge means for discharging the fired shaped products from the pallets. The pallets are covered with product holder plates, preferably plane parallel product holder plates, adapted approximately to the format of the respective shaped products. More uniform action of the firing atmosphere on the shaped products is thereby acheived. The product holder plates are more easily produced than the kiln furniture hitherto used.
    • 一种用于焙烧陶瓷制品的设备,特别是瓷器餐具,包括设置有通孔的窑和加热装置,用于在成形产品通过通孔期间保持成形产品的格栅托盘,用于将未烧成形产品 托盘上的排出装置和用于从托盘排出被烧制的成形制品的排出装置。 托盘覆盖有产品支架板,优选平面平行的产品支架板,其大致适应各个成形产品的格式。 因此,能够使成形品上的烧成气体的均匀动作更加均匀。 产品支架板比以前使用的窑具更容易生产。
