Abstract
Abstract The application describes a method and apparatus for roll pressure bonding a plurality of stripes to a substrate. Through unique roll arrangements and designs, stripes of controllable thickness are produced, as conditions which cause non-uniform roll pressures are eliminated. Furthermore, these unique roll arrangements and designs protect the substrate in the areas between the stripes from surface damage such as roll scratching. Additionally, novel means are provided which both guide and heat the materials.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
152 words
Apparatus for roll pressure bonding a plurality of spaced apart stripes to a substrate including in combination means for supplying a plurality of spaced apart widths of striping material; means for supplying a substrate; roll pressure bonding means for applying substantially uniform pressure to each width of striping during bonding, said bonding means comprising a lower work roll which contacts said substrate, a plurality of individually adjustable upper work rolls aligned to contact said plurality of spaced apart widths of striping material, said plurality of upper work rolls being spaced apart at distances corresponding at most to the respective distances between the spaced apart widths of striping material to which they are aligned; means for guiding said plurality of spaced apart widths of striping material to said roll pressure bonding means; and means for receiving said substrate from said roll pressure bonding means with said plurality of spaced apart stripes bonded thereto.
