FIELD: ceramic nozzle-type core of apparatus for producing of looped thread.
SUBSTANCE: ceramic nozzle-type core as part of texturing nozzle for producing of looped thread has wall with substantially constant thickness and is reduced in size in the region of thread processing channel functioning as main part where air blowing and discharge of thread for looping are performed. Thread processing channel has at least one cylindrical portion and at least one conical portion. Blowing device is positioned within cylindrical portion. Nozzle-type core is made by forming process.
EFFECT: increased quality of thread texturing and reduced core manufacture costs.
