Claim:
1. An oven for baking a thermally curing binder present in a mat of mineral fibers, comprising: a plurality of compartments through which the mat of fibers passes successively, the mat being compressed and configured to be transported through the compartments by gas-permeable upper conveyors and gas-permeable lower conveyors, each compartment including a top wall, a bottom wall, a first lateral side wall and a second lateral side wall that is opposite the first lateral side wall, each compartment having a length L along a direction of movement of the mat; means for introducing a hot air flow, which means is located either below or above the fiber mat; and means for extracting the air after the air has passed through the mat, the means for extracting arranged either above or below the fiber mat and opposite the means for introducing so that the fiber mat is positioned between the means for extracting and the means for introducing, and so that the binder is progressively brought to a temperature higher than its curing temperature; wherein at least one of the compartments includes the means for introducing a hot air flow, the means for introducing a hot air flow including an air inlet opening formed on the first lateral side wall of the at least one compartment and an air inlet opening formed on the second lateral side wall of the at least one compartment.
