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.
Claims8
Pneumatic thread stretcher, in particular for a rapier weaving machine or a knitting machine, comprising a substantially straight tube body having one end communicating with a pressurized air supply and remote from the one end having a blow-out end which defines a thread guiding channel and air current guiding channel, and an air current deflection surface arranged in front of the blow-out end substantially in the vicinity of a theoretical extension of the axis of the tube body, the air current deflection surface being bent in a blowing direction from the blow-out end in curved fashion away from the axis of the tube body, wherein the air current deflection surface is a seamless, sidewardly limited prolongation of an inner wall of the guiding channel.
