Provided is a method of producing an inorganic fiber mat, the method enabling efficient adhesion of an aldehyde scavenger to an inorganic fiber mat while preventing the aldehyde scavenger from scattering around. The method of producing an inorganic fiber mat includes a fiber collection step of applying a binder to inorganic fibers and accumulating in a mat-like shape on a conveyor line to form an inorganic fiber web, a binder-curing step of heat-curing the binder applied to the inorganic fiber web to form an inorganic fiber mat, and an aldehyde scavenger application step of applying an aldehyde scavenger to the inorganic fiber mat, in which the aldehyde scavenger application step involves spraying the aldehyde scavenger in a form of droplets having an average diameter of 1 to 50 &#x3bc;m on a front side of the inorganic fiber mat and sucking from a back side of the inorganic fiber mat.

Process for production of inorganic fiber mats

A resin film is provided wherein distortions generated at ear portions of films at shorter sides of a resin film coated heat insulating/sound absorbing material can be eliminated. The front and rear surfaces and both side surfaces in the direction of longer sides of the inorganic fiber mats are covered with band shaped resin films in a state that a predetermined spacing is provided between the mats, and the resin films are cut at a portion between the mats by a cutting blade along a direction of shorter sides in a state that the films are pressed by a pressing member, the resin films are pressed by the pressing member having film setting portions at both ends of a bottom surface thereof, whereby the slopes of the film setting portions prevent the ear portions of the resin films at the cutting portion from spreading sideways.
