Abstract: Apparatus and a method for winding a package positioned on a spindle assembly and held against a roller bail with substantially continually 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 functions to urge the package away from the roller bail as the spindle assembly approaches dead center and the weight of the package increases. Later, second and third springs come into play to urge the package against the roller bail. Preferably, the second spring comes into play and counteracts the primary spring well before the spindle assembly reaches dead center and the third spring comes into play when the spindle assembly is proximate dead center.
