Abstract
An apparatus and method of manufacturing a trim strip with an outer heat settable molding bonded to a base with an adhesive attaching member. The method includes heating a liquid heat settable material to be bonded to a hard base with an adhesive member at very low pressures to form a trim strip.
Claims22
A method of manufacturing a trim strip during a low pressure molding process comprising:
- providing a mold;
- pouring a desired amount of a liquid heat settable resin elastomer material into said mold, wherein said heat settable resin elastomer material is a plastisol;
- heating said mold containing said desired amount of heat settable material to cure said heat settable resin elastomer material;
- applying a backing member to said heat set material;
- bonding said backing member to said heat set material;
- thereby forming a trim strip at low pressure from said heat settable material and backing member;
- and
- removing said trim strip from said mold.

A trim strip formed by
- providing a mold;
- pouring a desired amount of a liquid heat settable resin elastomer material into said mold, wherein said heat settable resin elastomer material is a platisol;
- heating said mold containing said desired amount of heat settable material to cure said heat settable resin elastomer material;
- applying a backing member to said heat set material;
- bonding said backing member to said heat set material;
- and
- thereby forming a trim strip at low pressure from said heat settable material and backing member.
4 more elements
A trim strip comprising:
- a base layer having two sides, said base layer formed from a substantially hard or stiff plastic material;
- an adhesive tape layer positioned on one side of said base layer for bonding the trim strip to a surface;
- and
- an outer layer bonded to the other side of said base layer for providing an aesthetic appearance, said outer layer being a vinyl chloride resin elastomer wherein said vinyl chloride resin elastomer is a plastisol which is heat set prior to being bonded to said base layer during a low pressure molding process, said vinyl chloride resin elastomer originally being in a liquid form at the beginning of said low pressure molding process.
