Abstract
This invention relates to a flexibly and permanently interlocked manifold assembly of superimposed sheets or webs, and the method and apparatus for producing this assembly, wherein the superimposed sheets of the assembly are fastened by a stress-relieving means composed of crimps formed in one exterior sheet of said assembly and any intermediate sheets thereof; the crimps being formed in registry and the terminal margins thereof having an adhesive coated thereon and attached to the interior surface of the opposing exterior sheet of the said assembly.
Claims12
A manifold assembly comprising a plurality of superimposed flexible sheets and an exterior base sheet;
- fastening means for attaching said superimposed sheet to said base sheet;
- said fastening means comprising at least one crimp leg struck from each of said superimposed sheets and depressed toward the interior surface of said base sheet;
- said crimp legs having adhesive applied at their free terminal margins and attached thereby to the interior surface of said exterior sheet so that said crimp legs do not extend below said interior surface of said exterior base sheet;
- said crimp legs being depressed when attached to said interior surface of said exterior sheet at an angle of less than about 90.degree. from the plane of the sheets from which said crimp legs are struck when said sheets of said assembly are disposed in contiguous, unstressed planar alignment;
- said legs acting as stress-relieving members for fastening said superimposed and base sheets in planar alignment while permitting a reversible longitudinal shifting of said sheets with respect to each other in response to distortion of said planar alignment.
