Abstract
A method for forming and conditioning insulating felts of fibrous products whereby an insulating blanket is transported continuously on a transporting device, the insulating blanket is cut into a plurality of fiber strips, the fiber strips are driven by at least one branching-off and convergence device towards at least one reception conveyor, the fiber strips are superposed one on top of another so as to form at least one longitudinal stack, the at least one longitudinal stack is compressed by a compression device, and the compressed stack is cross cut to form the insulating felts. Such a method is implemented on a device including a transporting device, a longitudinal cutting device, at least one branching-off and convergence device, at least one reception conveyor, a compression device, and a cross-cutting device. The at least one branching-off and convergence device includes individual conveyor belts with each individual conveyor belt having a departure point at a junction of the transporting device and an arrival point aligned along a vertical axis and above the at least one reception conveyor. The fiber strips are superposed one above another on the at least one reception conv…
