ABSTRACT:
A roll carding unit, particularly for processing synthetic fibers for the oduction of non-woven textiles which includes a high-speed rotary drum and at least one worker roll rotating tangentially to the drum at a much lower speed than the latter to take up and card the fibres. Each worker roll is associated with two tile-shaped members which are disposed adjacent the surface of the drum upstream and downstream respectively of the position at which the latter touches the worker roll. The first member comprises an output section extending close to the zone of touching to convey the flow of fibers thereto and the second member comprises an input section at an angle to the surface of the drum to connect it with the surface of the worker roll.
