Heissklebeverfahren

摘要

An improved method by which a member having a surface comprising at least a polyolefin and a polyester portion and a member having a polyester surface are thermally fused together. The method comprises subjecting the polyolefin portion of said first surface to a flame treatment, then treating the polyester portion of said first surface and said polyester second surface with hot air, and finally compressing the two surfaces to be thermally fused. If desired, the polyolefin portion of the first surface may be subjected to a flame treatment and then treated with hot air while the polyester portion is only treated with hot air and the polyester second surface is treated with hot air. The method insures that the first surface comprising a polyolefin and a polyester portion is thermally fused to the polyester second surface to produce high bond strength.
