A fleece-laying apparatus with an upper carriage (4) and a laying carriage (5) which move above an output conveyor belt (2) transversely to the transport direction of that belt to lay a card web (11) supplied to the fleece layer in partially overlapping layers on an output conveyor belt (2), an endless card web conveyor belt (14) traveling exclusively in the laying carriage (5) wraps around at least one first laying roller (12) in the laying carriage (5). The belt has upper and lower strands (14o, 14u), which extend between the first laying roller (12) and a deflecting roller (15), which is supported in the laying carriage a certain distance away from the laying roller and around which the belt partially wraps. The lower strand (14u) of the web conveyor belt (14) traveling around exclusively in the laying carriage (5) passes only a very short distance away from the output conveyor belt (2), and its upper strand (14o), namely, a section of the upper strand adjacent to the laying gap, supports a length of the card web (11) to be laid from underneath. This length of the card web (11) is covered by the opposing section of another traveling card web guide belt (6).
