FIELD: process engineering.
SUBSTANCE: proposed device for production of said spool whereon test adhesive thread is wound comprises thread feed assembly with spool whereon thread is wound. It comprises also cutter to cut thread fed by said assembly into preset-length threads. It includes adhesive tape unwinding unit to feed adhesive tape and assembly unit to feed cuts of thread on adhesive tape surface at preset angle and spacing to allow thread cut free ends extend beyond adhesive tape edges. Unwinding unit that unwinds cover tape on adhesive tape surface and thread cuts applied thereon to produce test adhesive tape that comprises adhesive tape, cover tape and thread cuts fitted there between, as well as winding unit whereon test adhesive tape is wound. Invention covers also the method of producing above described spool and method of its use.
EFFECT: ease and efficient use in visualising air flows on surfaces of tested objects.
