A device (1) for drawing in and intermediately storing a thread (2), comprising a suction chamber (3), wherein the suction chamber (3) includes an entry opening (8) and an exit opening (9), which define a direction of flow, wherein negative pressure can be applied to the exit opening (9) in order to generate an air flow (4). Moreover, the device comprises a depositing surface (5) arranged in the suction chamber (3), on which the thread (2) can be intermediately stored, and a flow element (6) arranged in the suction chamber (3), with the aid of which the air flow (4) can be directed through the suction chamber (3). The suction chamber (3) is divided into a first region (14) and a second region (15) with the aid of the depositing surface (5) and the flow element (6) is displaceable between a first position, in which the air flow (4) is guided through the depositing surface (5) and through the second region (15), and a second position, in which the air flow (4) is guided past the depositing surface (5) through the first region (14). A textile machine comprising a plurality of workstations arranged next to one another in the longitudinal direction of the textile machine is characterized in that the workstations each comprise such a device. In a corresponding method for drawing in and intermediately storing a thread (2), the thread (2) is sucked into the suction chamber (3) with the aid of an air flow (4) and is intermediately stored on a depositing surface (5) arranged in the suction chamber (3). The air flow (4) is directed through the suction chamber (3) with the aid of the flow element (6). The suction chamber (3) is subdivided into a first region (14) and a second region (15) with the aid of the depositing surface (5) and the flow element (6) is displaced between the described positions.
