Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
239 words
Apparatus for winding a package, comprising means for engaging the periphery of the package during package winding, 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 control means operable as said holding means moves between said first and second positions to maintain a substantially constantly decreasing pressure between said package and said engaging means, said control means including first means for urging the 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, second means for urging said holding means toward said engaging means under increasing force correlated with increase in size of said package as said holding means moves in sAid second position, lever means arranged for pivotal movement relative to said holding means, said second means being connected with said holding means and said lever means, and means for locating said lever means to render said second means inactive during at least a portion of the movement of said holding means in said first position and thereafter render said second means active to exert said increasing force on said holding means.
Claim 2
Dependent Claim
239 words
Apparatus for winding a package, comprising means for engaging the periphery of the package during package winding, 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 control means operable as said holding means moves between said first and second positions to maintain a substantially constantly decreasing pressure between said package and said engaging means, said control means including first means for urging the 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, second means for urging said holding means toward said engaging means under increasing force correlated with increase in size of said package as said holding means moves in sAid second position, lever means arranged for pivotal movement relative to said holding means, said second means being connected with said holding means and said lever means, and means for locating said lever means to render said second means inactive during at least a portion of the movement of said holding means in said first position and thereafter render said second means active to exert said increasing force on said holding means.
Claim 3
Dependent Claim
71 words
Apparatus as set forth in claim 1 wherein said holding means is mounted for pivotable movement between said first and second positions, said lever means is pivotable in a sense corresponding to the sense in which said holding means is pivoted as said package increases in size, and said locating means for said lever includes stop means limiting the pivoting motion of said lever means as said package increases in size.
Claim 4
Dependent Claim
70 words
Apparatus as set forth in claim 2 wherein said holding means includes a frame with a spindle assembly mounted thereon proximate one end thereof for supporting said package; said first means is connected with said frame at a locus proximate the opposite end of the frame from said one end, and said second means is connected with said frame at a position intermediate said spindle assembly and said opposite end.
Claim 5
Dependent Claim
41 words
Apparatus as set forth in claim 3 wherein said frame is pivotable about a horizontal pivot positioned intermediate said spindle assembly and said opposite end, and said second means is connected with said frame between said pivot and said spindle assembly.
Claim 6
Dependent Claim
17 words
Apparatus as set forth in claim 1 wherein said second means includes a plurality of biasing elements.
Claim 7
Dependent Claim
61 words
Apparatus as set forth in claim 5 wherein said biasing elements include at least first and second extendable members, and including means mounting said first member in position to be extended and thereby exert a biasing force on said holding means for a predetermined interval before said second member is extended to exert a further biasing force on said holding means.
Claim 8
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 control 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 9
Dependent Claim
20 words
Apparatus as set forth in claim 1 wherein said second means is connected with said lever means by adjustable means.
Claim 10
Dependent Claim
33 words
Apparatus as set forth in claim 1 wherein said second means includes a plurality of extendable members, and said lever means includes a separate movable lever for receiving each of said extendable members.
Claim 11
Dependent Claim
34 words
Apparatus as set forth in claim 1 wherein said second means includes a plurality of extendable members, and said lever means includes a lever having one end of each of the members connected thereto.
