A heat insulating/sound absorbing material wherein the entire surface of an inorganic fiber mat is covered with a synthetic resin film or films and a method of producing the same. Front and rear surfaces of an inorganic fiber mat as well as both side surfaces along a longer side thereof are covered with synthetic resin films ; both ends of the synthetic resin films in the direction of a longer side of the inorganic fiber mat are extended from both ends in the direction of a shorter side thereof to thereby cover both end surfaces in the direction of a shorter side of the inorganic fiber mat ; an adhesive is applied continuously or discontinuously along the direction of a longer side of film to a portion in the direction of a shorter side of the inorganic fiber mat whereby the inorganic fiber mat and the synthetic resin films, and a mutually opposing portion of the synthetic resin films are bonded so as to make air communicate through unbonded portions.

Spherical products of a heat-softened material are produced by supplying a molten heat-softened material into a C-shaped channel-like spinner with an open upper surface and a large number of orifices formed in its circumferential wall, at a rate of 0.020 kg/hr or lower per a single orifice of the spinner; rotating the spinner at a high speed to form cone-like fine streams of the molten material from the orifices by means of a centrifugal force; and flowing streams of a hot gas so as to traverse the fine streams of molten material to thereby heat the same resulting in reducing the viscosity of the molten material and to break the fine streams by the hot gas streams.

In a method of restarting operations for manufacturing filaments from a molten mass of a thermoplastic material after the occurrence of the breaking of a filament, the filaments being drawn at a regular, high speed from a large number of orifices formed in the bottom of a bushing, a bead of the molten mass formed at an orifice where the breaking of a filament occurs is detected to thereby generate a signal; the speed of elongating the filaments is reduced upon receiving the signal so that a filament elongated in the vicinity of the bead at the reduced speed is brought into contact with the bead elongated by gravity, and elongates the bead into a filament having a larger diameter, during which operations to produce a regular filament product are stopped; and the speed of elongating the filaments is increased to the regular speed.
