Title:
PRODUCTION OF COMPOSITE PAVING MATERIAL
Document Type and Number:
Japanese Patent JP3479338
Kind Code:
B2
Abstract:
PURPOSE: To supply a kneaded material into a mold without a space by a method wherein a kneaded material of an aggregate with a melt plastic continuously discharged is preformed into a plate of a width slightly larger than the inner dimension of the mold, the plate is blanked into the same shape as the inner shape of the mold, and the blanked plate is put in the mold to be pressurized.
CONSTITUTION: A kneaded material is supplied to a calendering roll to be calendered into a plate having a predetermined thickness and a width slightly larger than the inner dimension of a mold. The planar material is continuously supplied to a large-size press and blanked into the inner shape of the mold by a blade. Next, the blanked planar material (a first layer) is supplied to the mold one by one to be placed and again pressurized in the mold. Therefore, the planar material can be supplied to all the corners of the mold.
