    Abstract: PURPOSE: To continuously produce a fiber-filled material to simply and easily obtain a long-sized cushion material by feeding mixed raw fibers, containing thermal-fusing fibers into a filling chamber together with an air current, heaping the mixed raw fibers while being allowed to collide with a shield body, guiding this heaped fiber lamp into a heat treatment chamber and integrating them. CONSTITUTION: Short fibers and thermal-fusing fibers are mixed by an opening and scutching machine and/or carding machine, and spread staple fibers are fed through a duct 1 and a fan 2 to a staple fiber supply port 3. A filling chamber 4 is disposed proximately to the staple fiber supply port 3, and filled material 8 is formed by being pressed and deposited here. Belt conveyers 5 and 5' are arranged in the filling chamber 4, and belt conveyers 7 and 7' are arranged in a heat treatment chamber 6 disposed proximately to the downstream of the filling chamber 4. The heat treatment chamber 6 has a heater, the filled material 8 is uniformly heated to the inside, and the mixed thermal-fusing staple fibers are fused by heating. A belt conveyer 9 is disposed on the downstream side of the heat treatment chamber 6, and the band-shaped filled material 8 is sent to the next process while being cut into any suitable length or is rolled up into package.

    Abstract: PURPOSE: To provide a fiber-filled material hardly causing deformation and uniform in filling density by laminating multiple thin layer webs in which staple fibers are arranged at random vertically to a plane, and mutually integrating these staple fibers through an adhesive agent. CONSTITUTION: Mixed raw fibers are formed by mixing various staple fibers with staple fibers composed of adhesive agents. The mixed raw fibers are worked by an opening and scutching machine and/or carding machine, then sent into a filling chamber 4 together with an air current by a fan 11. The mixed raw fibers are allowed to collide against a shield body 9 (wire net) in a filling chamber, then heaped laminatededly thereon. The heaped web constitutes a new shield body and further, the new mixed raw fibers are heaped thereon. The shield body 9 is retracted from the filling chamber with the lapse of time as the mixed raw fibers are deposited, and the heaped web is guided to a heat treatment chamber 6 as it is, heated to the melting point or above of thermal-fusing resins contained in the mixed raw fibers, fused and integrated. Thus, the short fibers are filled uniformly within the range of less than ±0.01 g/cm with respect to the average fiber filling density in the longitudinal direction of the fiber-filled material, and the fibers-filled material has a stripe- shaped pattern structure.
