Method for producing air-laid products

A device for producing an air-laid product or a non-woven fabric from at least one starting material, the device comprising:

• at least one comminution line with at least one comminuting device for comminuting at least one starting material into at least one comminuted material;
• at least one material buffer for receiving a comminuted material respectively assigned to the at least one material buffer, wherein the at least one material buffer includes at least one controllable metering device for metered removal of the respectively assigned comminuted material from the at least one material buffer and for feeding the at least one comminuted material to at least one processing line, wherein the at least one processing line includes at least one defibration system that is configured to defiberize the at least one comminuted material into at least a defiberized material;
• a production machine configured to produce an air-laid product or a nonwoven fabric from the at least one defiberized material;
• and
• a control unit configured to control the at least one metering device in such a way that a continuous mass flow of defiberized material is fed to the production machine.
