摘要： An automatic spinning start-up flyer for a roving frame which has on a flyer arm a swingably-mounted pressing finger comprised of a pressing finger bar and a pressing finger arm with a pressing finger blade. The pressing finger assembly is mounted on a pivot axis at the centrum of the connection of the pressing finger with the flyer arm and is rotated about the bobbin center. The pressing finger rod lies outside the radius along which the pressing finger arm with pressing finger blade are arranged and the pressing finger bar is actuatable by an actuating element effective transverse to the pivot axis upon the pressing finger bar to swing the pressing finger into its outwardly-swung position. With the flyer, a wide opening of the pressing finger can be effected automatically for automatic bobbin change without a loading of the pressing finger against the sleeve or bobbin. This is achieved in that the flyer arm has at least one spring element whose spring force is effective on the pressing finger only in a pivot region thereof in which the center of gravity of the pressing finger lies outside the radius.
