In order to reduce the required time when changing full hank rovings for empty roving tubes, it is proposed that the rotary conveyor chain (12), on which the empty roving tubes (14), which are provided for the changing procedure, are hanging, and onto which the full hank rovings (9) are hung during the changing procedure, is mounted in a bobbin table (11), which for the changing procedure can be moved into the flyer frame (1) between the lower edge of the wings (6) and the upper edge of the full hank rovings (9), which are positioned on the bobbin carriers (8) of the bobbin bank.
