Abstract. Dynamic model of unwinding yarn off the spool has been
formulated on the basis of previous research. The expressions for determination
yarn tensile force have been derived at the time of yarn separation from
the spool and creation of a balloon. The results obtained on the basis
of this model have been compared with experimental results of the research
and the evaluation of suitability of dynamic model has been made.
Key words: dynamic analysis, unwinding yarn off the spool
TEORIJSKA I EKSPERIMENTALNA ISTRAŽIVANJA
ODMOTAVANJA PREĐE SA KALEMA
U radu su izvršena teorijska i eksperimentalna istraživanja premotavanja
pređe sa kalema. Matematički model, postavljen na osnovu teorijskih i eksperimentalnih
istraživanja, dobro prati sam proces premotavanja što je utvrđeno upoređivanjem
rezultata sile zatezanja dobijenih teorijskim i eksperimentalnim putem.
