Abstract
PURPOSE:To facilitate adjustment of pressure application time, the compression rate of an air chamber is changed by changing the distance between a die and a bolster even if the time for one cycle of a crank shaft and the stroke thereof, are constant. CONSTITUTION:A die having a heat panel 5 whose temperature setting is freely adjustable is provided above a bolster serving as a receiving table for a material to be pressure-molded such as inorganic fiber crude boards before drying for example and can be clamped on and separated from the bolster 1. When subject to load at the lower position thereof, the die 2 does not descend to the lower limit B correspondingly to the cycle C of the rotation of a crank shaft 4, but to the contact point D thereof with the material, and compression is made during the contact time t of the die with the material. Therefore, compression time is adjustable by changing the distance between the contact point D and said lower limit B, and pressure by the pressure of a chamber 3.
