The present invention relates to a method for manufacturing insulation products based on mineral wool bound by an organic binder, comprising the following successive steps: (a) providing a mineral wool, (b) humidifying the mineral wool, (c) placing the humidified mineral wool fibers in contact with particles of binder comprising a mixture of thermosetting reagents, (d) shaping the mixture of mineral wool and binder particles, and (e) heating the shaped mixture to a temperature and for a period sufficient to allow the condensation of the reagents and the formation of an insulation product based on mineral wool bound by an insoluble and infusible organic binder.

A sheet manufacturing apparatus of the present invention includes a defibrating unit that defibrates a material containing fibers into a defibrated material, and a deposition unit that deposits a defibrated material defibrated by the defibrating unit. The deposition unit includes a material supply port through which the defibrated material from the defibrating unit is supplied, a plurality of opening ports through which the supplied defibrated material passes, and a dwell area disposed between the material supply port and the opening ports so that the defibrated material temporarily dwells in the dwell area. The dwell area allows the defibrated material to temporarily dwell in the dwell area so that a variation amount of the defibrated material that passes through the opening ports becomes smaller than a variation amount of the defibrated material supplied through the material supply port.

A method of making mounting mats comprising the steps of: (i) supplying inorganic fibers through an inlet of a forming box having an open bottom positioned over a forming wire to form a mat of fibers on the forming wire, the forming box having rollers for breaking apart clumps of fibers and an endless belt screen; (ii) capturing clumps of fibers on the endless belt; (iii) conveying captured clumps of fibers on the endless belt so as to enable captured clumps to release from the belt and be broken apart by the rollers; (iv) transporting the mat of fibers out of the forming box by the forming wire; and (v) compressing and restraining the mat of fibers to thereby obtain a mounting mat having a desired thickness suitable for mounting a pollution control element in a pollution control device.

A method for producing a shaped article includes a second web forming step, in which a mixture containing fibers and a binding material is deposited in the air, the binding material containing starch and an alkali metal salt; a moistening step, in which the mixture is supplied with water; and a sheet-forming step, in which heat and pressure are applied to the mixture supplied with water to give a sheet. The alkali metal salt content of the binding material is 2.0% by mass or less of the total mass of the starch.

A sheet manufacturing apparatus including a defibrating unit able to defibrate, in air, feedstock containing fiber; and a forming unit forming sheets, using at least part of defibrated material defibrated by the defibrating unit, by heating and pressurizing, and cutting; conveyance direction of the sheet in the forming unit being the short-side direction of the sheet.

An interior trim part made by a method that includes the steps of bringing a fiber web onto a conveyor, needlepunching the fiber web to form a base in contact with the conveyor, and introducing a binder component on the base. The binder component introduced on the base is a thermoplastic polymer in solid form. The method includes a step for heating the base to cause the thermoplastic polymer making up the binder component to penetrate the base over a thickness smaller than the thickness of the base.
