Abstract

A method of applying a strip to a surface is disclosed. The strip is laid out spaced apart from a path guide. The path guide is referenced with least two longitudinally spaced apart reference guides to guide an applicator transversely spaced from the reference guides over the strip. The strip is lifted upstream of the applicator with a strip guide longitudinally spaced from the applicator to space the strip from the surface. Heat is applied to at least one of the strip or the surface in a location longitudinally between the applicator and the strip guide. The applicator is moved along the strip to apply pressure to the strip against the surface to bond the strip to the surface. A related apparatus for applying the strip to the surface is also disclosed.
