Title: Manufacture of hydraulic inorganic molding
Inventor: MAESAKO HIROSHI
IPC: B28B3/16
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To continuously manufacture a totally homogeneous molding free from outer defects, with high accuracy by spreading a raw material while synchronizing the peripheral speed of the minimal diameter part of a spreading roll with the relative moving speed of a water permeable sheet against the spreading roll. SOLUTION: A water permeable sheet 2 is of the endless belt type and rotates at a constant speed in the A direction. A suction means 4 is equipped with a compression box 5 and plural suction boxes 6, and rotates at an equal speed in the same rotating direction as the water permeable sheet 2 to press an excess moisture contained in a raw material from a water suction hole through the water permeable sheet 2. A raw material supply device 3a, synchronizing its relative speed with the water permeable sheet 2 within a moving range W, spreads the raw material while shuttling back and forth in the moving direction of the water permeable sheet 2.  In addition, as the spreading roll 33 rotates synchronizing the peripheral speed of its minimal diameter part with the relative speed of the water permeable sheet 2, no friction is generated between an object to be shaped and the surface of the spreading roll 33. Consequently, the surface of the molding is not marred due to the causes for a defective appearance such as a tear-off and therefore, the reliable manufacturing of the hydraulic inorganic molding is achieved.
