  • Patent number: 4885843
    Abstract: A laminated guide bar is provided with a center or core laminate comprised of an adhesive-foam material that is configured to form the guide groove. The adhesive-foam core resists deformation, strongly adheres to the interfacing outer laminate sides, and is inert and impervious to oil. The core is formed in place between the outer laminates with a fixture surrounding the outer laminates and maintaining their spaced relationship. A cavity is provided in the fixture that conforms to the desired core configuration. The foam material has a controlled activation to allow assembly of the fixture and upon activation, produces the desired properties mentioned. It is desirable to roughen the inner sides of the outer steel laminates to assist the bonding action of the foam material.
