A system for fabricating a sheet product. A first rotatable roller includes a rotatable drum portion having an outer surface that rotates about a rotational axis in a first direction and conveys a sheet product. The rotatable drum portion also has a plurality of ports communicative between an inner surface and an outer surface. The ports extend along and around the drum portion. The first rotatable roller emits a pressurized fluid. A second rotatable roller has an outer surface arranged proximate to the outer surface of the rotatable drum portion of the first rotatable roller, and a heat source portion to heat the second rotatable roller to dry the sheet product. The second rotatable roller rotates in a second direction that is opposite to the first direction. A gap is defined between the second rotatable roller and the first rotatable roller through which the sheet product passes.

An oven for baking a thermally curable binder in a mat of mineral fibers, including plural compartments through which the mat of fibers passes successively, the mat being compressed and transported through the compartments by gas-permeable upper conveyors and lower conveyors, each compartment having a length along a direction of movement of the mat and including a mechanism introducing a hot air flow, located either below or above the fiber mat, and a mechanism extracting the air after having passed through the mat, respectively arranged either above or below the opposite face of the mat, so that the binder is progressively brought to a temperature higher than its curing temperature. In one compartment the mechanism introducing hot air includes air inlets that open partly on openings formed on a first lateral side of the compartment and partly on openings formed on the opposite lateral side of the compartment.
