	%X The aim of work is to define the distribution density of
winding yarn on cylindrical and conical bobbins. It is known that
parallel winding gives greater density and more regular distribution,
but the unwinding of yarn is much more difficult for following
process.
The conical spool has an enormous advantage during unwinding
and may contain a large amount of yarns, but the density distribution
is not regular because of difference in diameters. The variation of
specific density over the reel height is explained generally by the
sudden change of winding speed due to direction movement variation
of yarn. We determined the conditions of uniform winding and
developed a calculate model to the change of the specific density of
winding wire over entire spool height.
