Abstract
Abstract The interior structure of a tape laydown shoe or roller has an axle supporting solid rings, shoe members, and the like on ball joints. Thus, the solid members adapt to surface contour changes to back up an elastomeric facing element. The ball joints provide for force division of the principal tape head force into plural components directed at the contour surfaces.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
156 words
In a tape laminating machine having a tape laying head for dispensing and pressing tape to a tape laydown surface, and having means for directing a tape laydown force against said laydown surface, a tape presser member assembly carried by said head, comprising: (a) a base frame coupled to said head; (b) an axle carried by said frame with its longitudinal axis substantially normal to the direction of said tape laydown force to transmit said force radially through said axle; (c) force divider means carried by said axle for dividing said radial force into at least two separate radial components; (d) at least two solid members in contact with said force divider means, said members including means for mounting said members and providing limited movement of said members in multiple directions; (e) a distortable presser strip spanning and connected to said members; and (f) means for stabilizing and biasing said presser strip into an undistorted shape.
Claim 2
Dependent Claim
156 words
In a tape laminating machine having a tape laying head for dispensing and pressing tape to a tape laydown surface, and having means for directing a tape laydown force against said laydown surface, a tape presser member assembly carried by said head, comprising: (a) a base frame coupled to said head; (b) an axle carried by said frame with its longitudinal axis substantially normal to the direction of said tape laydown force to transmit said force radially through said axle; (c) force divider means carried by said axle for dividing said radial force into at least two separate radial components; (d) at least two solid members in contact with said force divider means, said members including means for mounting said members and providing limited movement of said members in multiple directions; (e) a distortable presser strip spanning and connected to said members; and (f) means for stabilizing and biasing said presser strip into an undistorted shape.
Claim 3
Dependent Claim
15 words
The tape presser assembly of claim 1, wherein said distortable presser strip comprises an elastomer.
Claim 4
Dependent Claim
64 words
The tape presser assembly of claim 1, wherein said force divider means comprises cooperating first inner and outer spherical raceways carried by said axle and a pair of cooperating second inner and outer spherical raceways carried by said first outer spherical raceway, the spherical center of said second inner raceways being spaced apart and non-coincident with the spherical center of said first inner raceway.
Claim 5
Dependent Claim
27 words
The tape presser assembly of claim 1, wherein said solid members are arcuate members, and wherein said presser strip subtends an arc of circumference on said members.
Claim 6
Dependent Claim
27 words
The tape presser assembly of claim 1, wherein said solid members ae cylindrical rings, and wherein said presser strip is a cylindrical sleeve fitted to said rings.
Claim 7
Dependent Claim
15 words
The tape presser assembly of claim 5, wherein said cylindrical sleeve is an elastomeric tube.
Claim 8
Dependent Claim
172 words
In a tape laminating machine having a tape laying head for dispensing and pressing tape to a tape laydown surface, and having means for directing a tape laydown force against said laydown surface, a tape presser member assembly carried by said head, comprising: (a) a base frame coupled to said head; (b) an axle carried by said frame with its longitudinal axis substantially normal to the direction of said tape laydown force to transmit said force radially through said axle; (c) a pair of force divider means axially-spaced on said axle, each carrying approximately half of the total radial force and each dividing its respective half of the force into two separate radial components; (d) at least four solid members in contact with said pair of force divider means, said members including means for mounting said members and providing limited movement of said members in multiple directions; (e) a distortable presser strip spanning and connected to said members; and (f) means for stabilizing and biasing said presser strip into an undistorted shape.
Claim 9
Dependent Claim
172 words
In a tape laminating machine having a tape laying head for dispensing and pressing tape to a tape laydown surface, and having means for directing a tape laydown force against said laydown surface, a tape presser member assembly carried by said head, comprising: (a) a base frame coupled to said head; (b) an axle carried by said frame with its longitudinal axis substantially normal to the direction of said tape laydown force to transmit said force radially through said axle; (c) a pair of force divider means axially-spaced on said axle, each carrying approximately half of the total radial force and each dividing its respective half of the force into two separate radial components; (d) at least four solid members in contact with said pair of force divider means, said members including means for mounting said members and providing limited movement of said members in multiple directions; (e) a distortable presser strip spanning and connected to said members; and (f) means for stabilizing and biasing said presser strip into an undistorted shape.
