the rolls of the drafting arrangement extending throughout the machine such as e g the bottom roll 9 are supported in the machine frame 3 in a manner known as such the longitudinal beam 4 is connected at both its ends with a respective arm 12 and 13 arranged at right angles thereto the beam 4 and the arms 12 13 forming a rigid frame or frame means 14 at their free ends the arms 12 and 13 are pivotably supported on a related pivoting axis or shaft 15 in the machine frame 3 in this arrangement the machine frame 3 is provided with an extension 16 the shape of the machine frame 3 however obviously can be chosen as desired the shafts or axes 15 of both arms 12 and 13 coincide i e are in alignment with one another and form the virtual longitudinal axis of the machine about which the flyers 5 of a row of flyers can be pivoted from their operating position into their doffing position furthermore the machine frame 3 contains a related stop 17 for each of the arms 12 and 13 respectively by means of which there is determined the operating position of the frame 14 and thus of the flyers 5 in fig1 the frame 14 is shown in the operating position in which the arms 12 and 13 are pressed against the stops or stop means 17 in this position the spindles 2 and the flyers 5 rotate about their axes and the delivery rolls 9 10 of the drafting arrangement deliver rovings 11 to each spinning position winding of the roving.
