Abstract
Abstract A spindleless spinning machine having a rotatable spinning turbine and coaxial outlet by which the thread is withdrawn. The device is provided with means having deflecting zones or surfaces, at the end of the outlet farthest from the turbine. This deflecting means is adjustable to selectively present one of a number of arrays and combination of deflecting surfaces to the thread, in order to obtain more selective results.
