Abstract: Apparatus for winding a package rotatably mounted on a spindle assembly and held against a roller bail with selectively adjustable decreasing winding pressure as winding progresses and the spindle assembly moves across dead center, with gravity first urging the package toward the roller bail and then away from the roller bail. Upon initiating winding, a primary spring urges the package in a direction away from the roller bail to reduce winding pressure and then second and third springs urge the package against the roller bail. The second and third springs are connected with a lever or, alternatively, each is connected with a respective lever, for adjusting the point at which these springs come into play to regulate the winding pressure.
