Abstract
Abstract An apparatus and method for applying a bead filler material to a bead wherein the bead filler material may be applied to the bead at an offset position to compensate for the stretching of the filler material as it is applied to the bead to afford a proper splice of the leading and trailing ends of the bead filler material.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
144 words
An apparatus for applying a filler to a bead comprising: (a) bead holding means adapted to hold said bead and to selectively rotate said bead; (b) transfer means adapted to grasp a leading end of said filler and place it adjacent said bead at a position offset from the bead holding means radial centerline and to grasp a trailing end of said filler and place it in abutting relationship with the leading end of said filler to form an aligned joint; (c) retention means for retaining an outer portion of the leading end of the filler on the bead holding means radially outwardly of the bead to reduce slippage of said outer portion on the bead holding means as the filler is wrapped about the bead; and (d) means for pressing the filler to said bead as said filler is wrapped about the bead.
Claim 2
Independent Claim
144 words
An apparatus for applying a filler to a bead comprising: (a) bead holding means adapted to hold said bead and to selectively rotate said bead; (b) transfer means adapted to grasp a leading end of said filler and place it adjacent said bead at a position offset from the bead holding means radial centerline and to grasp a trailing end of said filler and place it in abutting relationship with the leading end of said filler to form an aligned joint; (c) retention means for retaining an outer portion of the leading end of the filler on the bead holding means radially outwardly of the bead to reduce slippage of said outer portion on the bead holding means as the filler is wrapped about the bead; and (d) means for pressing the filler to said bead as said filler is wrapped about the bead.
Claim 3
Dependent Claim
39 words
The apparatus of claim 1 wherein said transfer means is adapted to affix said filler to said bead wherein the lateral axis of the filler is not perpendicular to the face of the bead to which it is applied.
Claim 4
Dependent Claim
48 words
The apparatus of claim 1 wherein said transfer means is comprised of: (a) manifold means selectively connectable to a vacuum source; (b) linea displacement means for displacing said manifold means in a first direction; and (c) linear displacement means for displacing said manifold means in a second direction.
Claim 5
Dependent Claim
14 words
The apparatus of claim 3 further comprising cutting means adapted to cut said filler.
Claim 6
Dependent Claim
21 words
The apparatus defined in claim 1 in which the retention means is a vacuum port formed in the bead holding means.
Claim 7
Dependent Claim
54 words
The apparatus defined in claim 5 in which the filler has inner and outer circumferential edges; in which the leading end terminates in an end edge; and in which the outer portion retained by the vacuum port is located adjacent a corner formed by the junction of the end edge and outer circumferential edge.
Claim 8
Dependent Claim
44 words
The apparatus defined in claim 6 in which the leading edge extends in an inwardly angled direction from the outer circumferential edge toward the inner circumferential edge as the end edge of the leading end passes the radial centerline of the bead holding means.
Claim 9
Dependent Claim
34 words
The apparatus defined in claim 1 in which the transfer means is a manifold selectively connectable to a vacuum source, and linear displacement means for displacing the manifold in at least two orthagonal directions.
Claim 10
Dependent Claim
131 words
In an apparatus for applying a filler to a bead wherein said bead is retained on a chuck and wherein the first end of said filler is applied to said bead the improvement comprising: applicator means adapted to apply said first end on said bead at position offset from the chuck radial centerline and to apply a second end of said filler on said bead in abutting relationship with the first end; means for affixing an outer end portion of said first end on the chuck to reduce slippage of said first end as the filler is wrapped about the bead; means for rotating the chuck while applying the filler thereto; and stitching means for affixing the filler to said bead and for pressing together the abutted ends of the filler.
Claim 11
Dependent Claim
131 words
In an apparatus for applying a filler to a bead wherein said bead is retained on a chuck and wherein the first end of said filler is applied to said bead the improvement comprising: applicator means adapted to apply said first end on said bead at position offset from the chuck radial centerline and to apply a second end of said filler on said bead in abutting relationship with the first end; means for affixing an outer end portion of said first end on the chuck to reduce slippage of said first end as the filler is wrapped about the bead; means for rotating the chuck while applying the filler thereto; and stitching means for affixing the filler to said bead and for pressing together the abutted ends of the filler.
Claim 12
Independent Claim
175 words
An apparatus for applying a filler to a bead comprising: (a) bead holding means adapted to hold said bead and to selectively rotate said bead; (b) transfer means adapted to grasp a leading end of said filler and place it adjacent the bead at a position offset from the bead holding means radial centerline; (c) retention means for retaining an outer portion of the leading end of the filler on the bead holding means radially outwardly of the bead to reduce slippage of said outer portion on the bead holding means as the filler is wrapped about the bead; (d) cutting means adapted to cut said filler after the filler is wrapped partially about the bead to form a trailing end; (e) said transfer means being adapted to grasp the filler as it is being cut by the cutting means and to place the trailing end adjacent the bead and leading end; and (f) roll means for pressing the filler to said bead and for pressing together the leading and trailing ends of said filler.
Claim 13
Independent Claim
175 words
An apparatus for applying a filler to a bead comprising: (a) bead holding means adapted to hold said bead and to selectively rotate said bead; (b) transfer means adapted to grasp a leading end of said filler and place it adjacent the bead at a position offset from the bead holding means radial centerline; (c) retention means for retaining an outer portion of the leading end of the filler on the bead holding means radially outwardly of the bead to reduce slippage of said outer portion on the bead holding means as the filler is wrapped about the bead; (d) cutting means adapted to cut said filler after the filler is wrapped partially about the bead to form a trailing end; (e) said transfer means being adapted to grasp the filler as it is being cut by the cutting means and to place the trailing end adjacent the bead and leading end; and (f) roll means for pressing the filler to said bead and for pressing together the leading and trailing ends of said filler.
