An improved, economical, high speed method and apparatus for attaching a fibrous material to a plastic substrate involves positioning a fibrous material over a surface of a plastic substrate, directing a stream of heated air through the fibrous material and at the surface of the plastic substrate to melt the surface of the plastic substrate, compressing the fibrous material against the melted surface of th e plastic substrate, and allowing the melted surface of the plastic substrate to cool and resolidify, whereby fibers of the fibrous material become embedded in the resolidified plastic. The apparatus generally comprises a fixture for supporting the plastic substrate and a fibrous material over a surface of the plastic substrate, a tool supported adjacent the fixture for directing heated, pressurized air toward the plastic substrate and for compressing the fibrous material against the plastic substrate, and an actuator for reciprocating the tool between a position in which the tool is spaced away from the plastic substra te and from the fibrous material, and a second position in which the tool compresses the fibrous material against the surface of the plastic substrate. |
