ABSTRACT:
A method of producing a mat consisting of filament loop aggregations. The first step is that of forming a first filament loop aggregation low in the filament density wherein many filaments are made. These by extruding a thermoplastic synthetic resin out of a T-die and arranging the resin longitudinally and laterally at intervals for continuous molding. The resin is deposited on a boiling water surface. The filament temperature is maintained close to the temperature at the time of molding by heating while the filament bundle is vertically lowered toward a cooling water surface and is sunk into water in the vertical direction. It is lowered at a speed less than the filament extruding molding speed, while a high density thermoplastic synthetic resin layer is conveyed under heating by a conveyer controlled to be at a feeding speed equal to the sinking speed in water of the above mentioned filament loop aggregation and is sunk into the cooling water along the outside of the filament loop aggregation at the delivery end. The filament loop aggregation and thermoplastic synthetic resin layer are fused together on their contact surface.
