Abstract (en)

A method of controlling a textile machine comprising a row of workstations arranged next to each other (1), in which at each workstation the presence of the sliver (2) is continuously monitored before entering an entry silver (2) device independently of the other workstations. At each workstation (1) the presence of the sliver (2) is monitored at least at a distance (Y) in front of a member for yarn formation, whereby the distance (Y) is determined by the velocity of the sliver (2) motion and the period necessary for the controlled stopping of the workstation with yarn (P) situated in the travel path at the workstation when the yarn (P) end is not wound on the bobbin (C) after stopping the workstation. The invention also relates to a textile machine comprising a row of workstations arranged next to each other (1), each of which comprises a member for yarn formation, behind which are in the direction of the movement of the fibrous material arranged other subunits for yarn formation (P), for drawing-off yarn and for winding yarn on a bobbin (C), whereby at each workstation is arranged a detector (6) of the presence of sliver (2). The detector (6) of sliver (2) is located at each workstation at a distance (Y) in front of the member for yarn formation, whereby the distance (Y) is determined by the velocity of the movement of the sliver (2) and the period of time required for the controlled stopping of the workstation with yarn (P) in the travel path at the workstation when the yarn (P) end is not wound on the bobbin (C) after stopping the workstation.
