A breathing circuit component includes an inlet, an outlet and an enclosing wall. The enclosing wall defines a gases passageway between the inlet and the outlet. At least a region of the enclosing wall is formed from a breathable material that allows the passage of water vapor without allowing the passage of liquid water or respiratory gases. The breathing circuit component is the expiratory limb of a breathing circuit.

The invention relates to a device (1) for manufacturing an unconsolidated textile elongate member (11), the device comprising a frame (2) with a longitudinal main guide (3) in a direction X, said main guide (3) being attached to the frame (2) and two modules (4) arranged in series around the guide (3) in direction X, each module (4) comprising a feed ring (5) surrounding a section of the guide (3), feed means (6) arranged on the ring (5) and capable of feeding at least one ribbon (10) to the main guide (3) at a feed rate V1, each ribbon (10) being capable of winding around the main guide (3) or onto the upper layer of ribbon (10), and means (15) for driving the ring (5) which are capable of rotating the ring (5) at a speed of rotation V2.
