Abstract (en)

A fine spinning machine includes a fiber bundle condensing device (3) that condenses a fiber bundle drafted by a drafting device (1) that includes a delivery roller pair (2). The fiber bundle condensing device includes a nip roller pair (7) disposed downstream of the delivery roller pair (2), a suction pipe (5) disposed upstream of the nip roller pair (7) and downstream of the delivery roller pair (2), and an air-permeable apron (6). A circumferential velocity ratio of a first drive roller (2b) to a second drive roller (7b) is modifiable. The fiber bundle condensing device (3) includes a pressing mechanism (11) configured to press a first driven roller (2a) or a second driven roller (7a) such that the first driven roller (2a) or the second driven roller (7a) is pressed against the first drive roller (2b) or the second drive roller (7b), and against the air-permeable apron (6).
