Abstract
An arrangement and method for spinning a yarn from a plurality of yarn components includes a drafting arrangement, a condensing zone arranged downstream thereof and also a ring spindle which twists all yarn components jointly. The condensing zone has a stationary sliding surface for a perforated transport belt which transports the yarn components through said condensing zone. At least one suction slit is located on the sliding surface, which suction slit extends essentially in a transport direction of the yarn components. The condensing zone is defined on its exit side by a nipping roller, which presses the yarn components and the transport belt onto the sliding surface. The at least one suction slit extends to the nipping point. The yarn components may be a sliver or roving and a core yarn, or two slivers or rovings, which, with or without any core yarn, together form the subsequent yarn.
