Abstract: The machine has a framework (1) with a rotation drive, spinning stations, a yarn withdrawal unit (2) and yarn winding devices (3) disposed thereon. Each spinning station comprises a fibres feed unit (4) and a spinning chamber (5), having a housing (14) installed on the framework (1) so that it can be withdrawn from the fibres feed unit (4). The yarn withdrawal unit (2) comprises a driving shaft (22) mounted on the framework (1), and pressing rollers (23), which in operating position are resiliently pressed to the driving shaft (22) and can be withdrawn from said driving shaft. Each yarn winding device (3) is mounted at a respective spinning station and comprises a bobbin carrier (27) and a yarn spreader (28). According to the invention each pressing roller (23) is mounted on the housing (14) of the respective spinning chamber (5), and each yarn winding device (3) has operative connection (31) with the housing (14) of a respective spinning chamber (5) to disengage and engage the rotation drive.

Abstract: The drawing mechanism comprises a housing accommodating a feed couple defined by a pair of endless belts. One endless belt is mounted about a driving cylinder, and moves in engagement with a movable guide and transmits motion to the other belt running about the pressure roller of the feed couple and said other belt moves in engagement with a stationary guide, and the drawing mechanism also includes a delivery couple defined by its own driving cylinder and its own pressure roller. At the inlet of the feed couple there are mounted a guiding member and a compacting member adapted to precompact the fibrous product being fed into the feed couple. The pressure roller of the delivery couple and the pressure roller of the feed couple, the stationary guide of the feed couple, the compacting and guiding members are mounted on a common removable plate provided with an adjustable retainer means for retaining the common removable plate in its position.
