Abstract
The invention relates to a pneumatic thread stretcher (T) for a rapier weaving machine or a knitting machine, in which the air current deflection surface (19) for deflecting the thread (Y, Y1) forms a seamless extension (12) of the inner wall of the linear guide channel, through which the thread runs. The invention also relates to a device (H) for changing the flow rate or the pressure of the air current along the deflection surface (19) of the pneumatic thread stretcher (T) between at least two different levels, in accordance with the operating cycle o the textile machine.
