Abstract
PURPOSE:To obtain a speaker cone with ribs which is free from shrinkage in the paper-making process by putting the paper-making mesh of the head-cut conical shape containing concavities to be the ribs into the tank with the head-cut part turned upward and then flowing the mesh into the tank together with the fiber like the pulp or the like plus the water. CONSTITUTION:Paper-making mesh holding mold 7 and paper-making mesh 6a are attached to paper-making tank 1 with the face to be outside of the cone set toward opening part 2 and the face to be inside set toward overflow 3 respectively. For mesh 6a, flange 11a is provided to conical paper-making mesh 11, and pieces 13 are arranged in the circumference and radiation directions with fixed space 12 secured between the pieces. The bottom surface is formed in accordance with the curvature of mesh 6a and with hole 14 drilled. The water mixed with the fiber like the pulp or the like is flowed into tank 1. The water is exhausted through overflow 3 by opening exhaustion valve 4, and the fibers are collected thick at mesh 11 and groove part 12 and collected thin to piece 13 each. Thus, a speaker cone with ribs can be formed. With draw-out of such cone from the tank and drying, a rigid and malformation-free speaker cone can be obtained through the paper-making process.
