Abstract
A method for making multi-colored composite laminates comprises stacking a plurality of colored strips in a predetermined pattern and bonding the strips into a composite laminate by continuous bonding. The composite laminate is then rolled before being passed through a deep steel pattern roll which forms a raised pattern on its surface. Next, the laminate is passed through a skiving table where the raised pattern is skived off to expose the multi-colored pattern formed by the underlying layers. The laminate is than flat rolled to a finished dimension and may be reeled up into a cylindrical roll.
Claims23
A method for making multi-layered composites comprising the steps of:
- stacking a plurality of sheets in a predetermined color sequence;
- solid-phase bonding said sheets into a composite laminate;
- forming a raised pattern on an outer surface of said laminate by passing said laminate through a patterned roller;
- removing said raised patterns to form a substantially flat surface and to expose portions of sheets other than said outer surface;
- and
- rolling said composite laminate to a finished dimension having a flat surface and color design thereupon due to said exposed sheet portions.
A method for making multi-colored composite metal laminates comprising the steps of:
- stacking a plurality of colored metal alloy sheets in a predetermined color sequence;
- bonding said sheets into a composite laminate having layers of different colored metal alloys;
- rolling said laminate to a predetermined thickness to ensure complete cohesion of said sheets;
- passing said multi-colored composite laminate through at least one deep steel pattern roller thereby forming a raised pattern on at least one outer surface thereof;
- removing said raised pattern to form a substantially flat surface and to expose a multi-colored pattern formed by portions of said different color sheets;
- and
- flat rolling said composite laminate to a finished dimension.
A method for making multi-layered color karat gold alloy composite laminate comprising the steps of:
- stacking a plurality of color karat gold alloy strips in a predetermined color sequence;
- bonding said strips into a composite laminate by continuous bonding;
- rolling said laminate to a predetermined thickness to ensure complete cohesion of said sheets;
- passing said laminate through a deep steel pattern roller thereby forming a raised pattern on at least one outer surface thereof;
- passing said laminate through a skiving table wherein said raised pattern is skived off to form a substantially flat surface and to expose a multi-colored pattern formed by portions of said different color sheets;
- and
- flat rolling said composite laminate to a finished dimension.
A method for mass producing reproducible multi-colored composite metal laminates comprising the steps of:
- stacking a plurality of colored metal alloy sheets in a predetermined color sequence wherein at least one of said sheets has a color contrasting to the other sheets;
- solid-phase bonding said sheets into a composite laminate;
- embossing at least one outer surface of said composite laminate by passing the laminate through a patterned roller to form an embossed pattern;
- removing said embossed pattern to form a substantially flat surface and to expose portions of sheets other than said outer surface;
- and
- rolling said composite laminate to a finished dimension having a flush surface and repeatable color design thereupon due to said exposed sheet portions.
