FIELD: textile industry, in particular, equipment for pneumatic mechanical spinning machine.
SUBSTANCE: apparatus has feeding cylinder, quantizing drum, transportation channel, spinning chamber equipped with rod fixed on spinning chamber bottom in axially aligned relation with respect to said chamber. Rod has thickened part and sharpened end at zone of contacting with fibrous ribbon. Two-pole permanent magnet of variable section is located within rod and is made from high-coercivity alloy having coercive force of at least 600 kA/m. Generatrix of rod thickened part at zone of contacting with fibrous ribbon is parabola continued with straight line.
EFFECT: increased efficiency of apparatus providing improved frictional and strength properties of fibers and allowing fibers of more homogeneous yarn structure and increased physical and mechanical properties to be created.
