Abstract (en)

[origin: WO2008145356A1] The invention relates to a method for production of a mineral wool product, in which a raw unbonded web (3) composed of mineral wool provided with an unhardened binder is passed, on a conveyor device, for the shaping of the product and for the hardening of the binder, into a curing oven (2) designed in the manner of a tunnel oven, and having an upper belt (21) and a lower belt (22). According to the invention, between the raw unbonded web (3) and the upper belt (21) and/or the lower belt (22) here there is a permeable separator belt (5) arranged. The invention further relates to a corresponding apparatus (1) and to a mineral wool product produced therewith. The result is an improved method of production of a mineral wool product, where in particular the cost of downstream operations on the mineral wool products discharged from the curing oven can be reduced.
