  • Method for attaching fibrous batt to plastic substrate
    Publication number: 20030146544
    Abstract: An improved, economical, high speed method 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 the 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.
    Type: Application

  • Apparatus for attaching fibrous batt to plastic substrate
    Patent number: 6530773
    Abstract: An 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 to melt the surface of the plastic substrate, compressing the fibrous material against the melted surface of the 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 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.
