Abstract
The present invention concerns a flyer for roving frames. According to the invention the flyer arms (14,16) at their free ends are connected rigidly with a ring (17). Furthermore, an enclosed guide duct with a guide tube (22) is provided for the roving, which guide tube (22) is supported to be pivotable about its longitudinal axis and supports a presser finger (25). Thus, a flyer of relatively low weight results, but of high solidity, permitting high rotational speeds. The guide duct for the roving can be of enclosed shape over a maximum of its length.
