Abstract: 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.

Abstract: A drying oven for crosslinking a continuous mat of mineral or plant fibers includes a plurality of heating boxes through which the mat of fibers successively passes. At least one of the boxes includes, between an external insulating jacket of the drying oven and a central compartment of the box, an in-built hot-gas heating and recirculation device that includes at least one radial turbine mounted horizontally, the axis of rotation of which is arranged vertically, the turbine drawing hot gas along the axis through a gas outlet orifice of the central compartment after it has passed through the mat, and discharging it radially toward a recirculation device that recirculates the hot gas leaving the radial turbine to a gas inlet orifice of the compartment, and at least one heating device for heating the gas circulating in the box.

Abstract: This forming device is intended to be mounted on a flight (6) of a conveyor for transporting a fibrous product through a heating device, where the flight (6) defines a receiving surface (63) for the fibrous product. The forming device has a forming block (8), a main part (81) of which is intended to be arranged at the front of the receiving surface (63), and at least one anchoring element (9) which is intended to be fixed to the flight by being arranged at the rear of the receiving surface (63).
