Method and apparatus for molding fiber mixture

摘要

A method and apparatus for molding a cushion member from a fiber mixture (1) by a filling process comprising filling a fiber mixture (1) composed of synthetic matrix fibers and binder fibers dispersed therein into a mold cavity (c) of an air-permeable mold (6,7) by a transportation air stream and a heat-treatment process comprising making a molding air stream for heating and/or cooling the fiber mixture filled in the mold cavity to pass through the fiber mixture, wherein a contact surface of the mold with the fiber mixture is divided into a plurality of contact sections, and a flow rate and/or pressure of an air stream passing through each of the contact sections are regulated to a predetermined condition so that the air stream in the mold cavity is differently controlled in the filling process and the heat-treatment process.
