Abstract
A discharge device for discharging solids of a thermoplastic substance and fibers includes a discharge passage extending longitudinally and having an inner wall surface forming a passage opened at its lower end, a solid supply device for supplying the solids of the thermoplastic substances to a first position in the passage and a fiber supply device for supplying the fibers to a second position in the passage. A cross line on which a part of the inner wall surface extending downward from an upper one of the first position and the second position intersects a vertical plane forms an angle of 0 to 30.degree. with respect to a vertical line, or all tangent lines for the cross line form angles from 0 to 30.degree. with respect to a vertical line.
