Abstract
A drywall trim device incorporating a metal core covered on the exterior by a cover strip fabricated from fibers mixed with a strengthening compound to encapsulate the fibers. The method of the invention may involve mixing the strengthening compound with the fibers in a beating process, putting the fiber in a film or layer and drying the film or layer before bonding to the metal core by a bond.
Claims24
A drywall trim device for drywall construction, comprising:
- an elongated metal rigid core configured with at least one flange formed with inward and outward facing surfaces;
- a cover constructed throughout its thickness of fiber segments encapsulated with strengthening compound at the time of manufacture and curing such mixture in a strip;
- and
- a bond bonding said strip to said outer surface of said flange.
A method of making a drywall trim for use in drywall construction, including the following steps:
- selecting a metallic core having an outer surface;
- manufacturing a material layer including mixing fibers with a strengthening compound to encapsulate such fibers in said strengthening compound;
- thereafter making a covering strip from such material layer;
- and
- adhering said strip to such outer surface to provide a cover to such core.
A drywall trim device for dry wall construction prepared by a process, including the following steps:
- selecting a metallic core having an outer surface;
- manufacturing a material that is composed of cellulose fiber mixed with a strengthening compound to encapsulate such fibers in the strengthening compound;
- making a covering strip from said material;
- and
- adhering said strip to said outer surface.
A drywall trim device for dry wall construction prepared by a process including the following steps:
- selecting an elongated angular metallic core having an outer surface;
- selecting a material that is made by many cellulose fibers mixed with a strengthening compound to encapsulate such fibers in said strengthening compound;
- making a covering strip from said material;
- and
- adhering said strip to such cater surface to provide a cover to such core.
A drywall trim comprising:
- a core having an outer surface;
- a covering strip fabricated by mixing fiber segments and a strengthening compound during manufacture to encapsulate said fiber segments and to fill pores between the fiber segments to inhibit concentration therein of moisture and consequent contraction of such strip relative to said core upon exposure to a reduced humidity environment;
- and
- a bond bonding said strip to said outer surface.
A drywall trim device for drywall construction, comprising:
- an elongated metal core configured with at least one flange formed with an inward facing surface and an outward facing surface;
- a cover fabricated from synthetic fiber segments encapsulated throughout at the time of manufacture by a strengthening compound;
- and
- a bond bonding said strip to said outer surface of said flange.
