Document Type and Number:
Japanese Patent JPH10505297
Kind Code:
A
Abstract:
A method and apparatus for producing tubular molded products from molding material includes a mold casing and a mold core having a common longitudinal central axis which is vertically disposed. The mold casing and mold core are spaced from one another to define a molding space therebetween. A supply device supplies molding material from above the molding space into the molding space. Treatment apparatus is disposed at treatment zones on the mold core for treating the molding material in the molding space, the treatment including treating the molding material by shaking the molding material or treating the molding material by heating the molding material, or both. The mold casing has an axial length which is less than an axial length of the molded product, to be produced and apparatus is provided for lowering a lower end of the column of molding material in the molding space in a direction parallel to the central axis from an initial position to a lowered position which enables production of a molded product of a desired longitudinal length.
