Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
169 words
Apparatus for winding a package comprising, means for engaging the periphery of the package during winding thereof, means for holding the package, means mounting the holding means for movement between a first position where the holding means is gravitationally biased toward said engaging means during a first interval of package winding and a second position, where said holding means is gravitationally biased away from said engaging means as said package increases in size, and regulating means for maintaining substantially constant decreasing pressure between the package and the engaging means during movement of the holding means between said positions, said regulating means including first means for urging said holding means away from said engaging means under a decreasing force correlated with increase in size of said package as said holding means moves toward said second position, and second means for urging said holding means toward said engaging means Under an increasing force correlated with the increase in size of said package as said holding means moves in said second position.
Claim 2
Dependent Claim
169 words
Apparatus for winding a package comprising, means for engaging the periphery of the package during winding thereof, means for holding the package, means mounting the holding means for movement between a first position where the holding means is gravitationally biased toward said engaging means during a first interval of package winding and a second position, where said holding means is gravitationally biased away from said engaging means as said package increases in size, and regulating means for maintaining substantially constant decreasing pressure between the package and the engaging means during movement of the holding means between said positions, said regulating means including first means for urging said holding means away from said engaging means under a decreasing force correlated with increase in size of said package as said holding means moves toward said second position, and second means for urging said holding means toward said engaging means Under an increasing force correlated with the increase in size of said package as said holding means moves in said second position.
Claim 3
Dependent Claim
78 words
Apparatus as set forth in claim 1 wherein the holding means includes a frame positioned for rotational movement about a horizontal axis, and a spindle assembly mounted proximate one end of said frame for supporting said package; said first means is connected with said frame at a locus proximate the opposite end of said frame from said one end, and said second means is connected with said frame at a position intermediate said axis and said one end.
Claim 4
Dependent Claim
42 words
Apparatus as set forth in claim 1 wherein said holding means includes a plurality of biasing elements, said elements being arranged to operate sequentially to provide an increasing force on said holding means as said package moves progressively in said second position.
Claim 5
Dependent Claim
62 words
Apparatus as set forth in claim 3 wherein said plurality of biasing elements includes at least first and second extension springs; and means mounting said first spring in position to be extended and thereby exert a biasing force on said holding means for a predetermined interval before said second spring is extended to exert a further biasing force on said holding means.
Claim 6
Dependent Claim
41 words
Apparatus as set forth in claim 4 wherein the engaging means is a horizontally oriented roller bail, said holding means includes a frame rotatable about a horizontal axis, and said roller bail is positioned in a plane below said horizontal axis.
Claim 7
Dependent Claim
56 words
Apparatus as set forth in claim 1 wherein said holding means passes through a dead center position in its movement from said first to said second position, and said second means is operable to exert a biasing force on said holding means toward said engaging means as said holding means passes through said dead center position.
Claim 8
Independent Claim
126 words
A method of winding a package comprising the steps of, engaging the periphery of the package with engaging means to thereby support said package for rotation during winding, mounting the package in position to be gravitationally biased toward the engaging means during a first interval of package winding and to be gravitationally biased away from the engaging means during a second interval of package winding as the package increases in size, and urging said package away from said engaging means during said first winding interval under a decreasing force correlated with increase in size of the package, and urging said package toward said engaging means under increasing force correlated with increase in size of said package as said package moves in said second interval of winding.
Claim 9
Independent Claim
126 words
A method of winding a package comprising the steps of, engaging the periphery of the package with engaging means to thereby support said package for rotation during winding, mounting the package in position to be gravitationally biased toward the engaging means during a first interval of package winding and to be gravitationally biased away from the engaging means during a second interval of package winding as the package increases in size, and urging said package away from said engaging means during said first winding interval under a decreasing force correlated with increase in size of the package, and urging said package toward said engaging means under increasing force correlated with increase in size of said package as said package moves in said second interval of winding.
Claim 10
Dependent Claim
54 words
A method as set forth in claim 7 including the step of passing said package through a dead center position between said first and second winding intervals, and urging said package toward said engaging means under a force correlated with the size of said package as said package passes through said dead center position.
Claim 11
Dependent Claim
27 words
A method as set forth in claim 7 wherein the step of applying a force during the second winding interval includes sequentially applying a plurality of forces.
Claim 12
Dependent Claim
54 words
A method as set forth in claim 7 wherein the step of applying a force during the first winding interval continues at least until the commencement of the step of applying the force during the second winding interval, and the force applied during the second winding interval continues until winding of the package terminates.
