  • Patent number: 4925511
    Abstract: The invention relates to a method of fitting a plate member with at least one supportive or protective member of a synthetic resin by injection molding of the resin with insertion of, for each resin member, a predetermined marginal region of the plate member in the mold cavity. For example, a vehicle window glass is fitted with two holders to be coupled with a window regulator mechanism. To enhance strength of adhesion of the molded resin member(s) to the plate without making any mechanical or thermal treatment of the plate, the marginal region of the plate is closely covered with at least one sheet of plastic film, which has a thickness of 5 to 250 .mu.m and becomes a melt adhesive to both the plate and the molded resin at a temperature in the range from 50.degree. to 150.degree. C., prior to insertion of the marginal region of the plate into the mold cavity. For example, the plastic film is of an ethylene base copolymer.
