Abstract
An improved method and apparatus for making yarn packages of cheese form by winding units of a textile machine, wherein a bobbin of a yarn package is rotatably supported by each cradle turnably supported by a pivot shaft secured to a bracket in such a condition that the contacting pressure between a yarn package and a friction roller for rotating the yarn package is gradually decreased in an exponential manner according to the increase in the size of the yarn package and the above-mentioned change of the contacting pressure is attained by utilizing means for compensating the contacting pressure which connects the cradle with the bracket.
