An apparatus for producing a nonwoven fabric from crimped fibres, in particular from crimped continuous filaments, wherein at least one spinning device or at least one spinning beam is provided for spinning the fibres, wherein an air-permeable deposit conveyor, in particular a depositing foraminous belt is provided for depositing the fibres in a deposition region to form a nonwoven web, wherein in the conveying direction of the nonwoven web at least one first pre-consolidation device for the pre-consolidation of the nonwoven web is provided downstream of the deposition region, wherein at least one suction device is provided by means of which air or process air in the deposition region of the fibres and/or in the region of the first pre-consolidation device can be sucked through the deposit conveyor or through the depositing foraminous belt, wherein at least one second pre-consolidation device for pre-consolidation of the nonwoven web is provided downstream of the first pre-consolidation device in the conveying direction of the nonwoven web, wherein in the region of the second pre-consolidation device air or process air can be sucked through the deposit conveyor or through the depositing foraminous belt, wherein in the region between the first pre-consolidation device and the second pre-consolidation device at least one suction gap section is provided, wherein in the suction gap section no suction of air or process air takes place through the deposit conveyor or through the depositing foraminous belt and/or wherein the suction gap section is adapted with the proviso that a smaller or a significantly smaller suction of air or process air takes place there than in the deposition region of the fibres and/or in the region of the first pre-consolidation device and/or that a smaller or a significantly smaller suction of air or process air takes place there than in the region of the second pre-consolidation device, and wherein the entire suction gap section is arranged on the deposit conveyor on which the fibres can be deposited to form the nonwoven web and on which the pre-consolidations take place with the at least two pre-consolidation devices. wherein at least one second pre-consolidation device for pre-consolidation of the nonwoven web is provided downstream of the first pre-consolidation device in the conveying direction of the nonwoven web, wherein in the region of the second pre-consolidation device air or process air can be sucked through the deposit conveyor or through the depositing foraminous belt, wherein in the region between the first pre-consolidation device and the second pre-consolidation device at least one suction gap section is provided, wherein in the suction gap section no suction of air or process air takes place through the deposit conveyor or through the depositing foraminous belt and/or wherein the suction gap section is adapted with the proviso that a smaller or a significantly smaller suction of air or process air takes place there than in the deposition region of the fibres and/or in the region of the first pre-consolidation device and/or that a smaller or a significantly smaller suction of air or process air takes place there than in the region of the second pre-consolidation device, and wherein the entire suction gap section is arranged on the deposit conveyor on which the fibres can be deposited to form the nonwoven web and on which the pre-consolidations take place with the at least two pre-consolidation devices.
