1. A device for producing a three-dimensional shaped consolidated fibrous product from a fibrous base material, comprising:
a rotary drum, defined as a rotary conveyor with a peripheral surface extending in a circumferential direction, with at least one product shaping area in the form of at least one cavity being formed on said peripheral surface, the peripheral surface is pervious to air at least in the product shaping area;
at least one fiber feed device to feed the fibrous base material into the at least one cavity, the fiber feed device arranged to feed the fibrous base material substantially as single fibers or particles;
a vacuum device designed to generate a negative pressure at least in the at least one cavity, thereby generating suction directed towards an interior of the rotary conveyor;
at least one consolidating device that comprises at least one heating device configured to provide thermal energy to the at least one cavity and fibrous base material contained in the at least one cavity, the at least one consolidating device being located downstream of the fiber feed device and heat-sets the fibrous base material by subjecting it to a consolidating treatment whereby the fibers in the fibrous base material in the cavity are at least partially adhered; and
wherein the rotary drum is defined by a first zone and a second zone, and wherein the at least one heating device is configured to provide a heat of a first temperature to the first zone and heat of a second temperature to the second zone.
