る。2. Description of the Related Art In recent years, a synthetic resin window frame material has been used together with a metal window frame material as a window frame material for a window sash. This synthetic resin window frame material has been widely used for window sashes because it is inexpensive to manufacture as compared with metal window frame materials, and has excellent heat insulation properties and is hardly dewed. I have. On the other hand, synthetic resin window frame materials have drawbacks in that they are inferior in terms of weather resistance and heat resistance and are inferior in terms of design, but acrylic resin with excellent weather resistance and heat resistance is provided on the surface of the window frame material. A resin coating sheet made of, for example, or a decorative coating sheet that has been subjected to wood grain printing or the like is attached to improve weather resistance and heat resistance, or to improve design.

下せしめるという新たな欠陥を発生させていた。[0003] The window frame of the synthetic resin window frame material is joined by heat welding in a state where the end surfaces of both ends of the synthetic resin window frame material are abutted to each other, and the window frame body assembled by this heat welding. Is used to compose a sash window. However, if the synthetic resin window frame material is joined by heat welding with the end faces thereof abutting against each other, a raised weld bead portion is formed at the welded joint portion. Therefore, it is necessary to remove and correct the weld bead portion. When the bead portion is removed by cutting or the like, the tint on the resin surface changes to white at the bead-removed portion (brushing)
This has caused a new defect of significantly reducing the appearance of the sash window frame product.

According to this prior art, a cover sheet is adhered to the surface of a synthetic resin window frame material, and a relief portion that is brought into a non-contact state with the adhered portion of the cover sheet when these are joined to the butted end surfaces of both members to be joined. Are formed mutually, and the butt portion avoiding the relief portion is fused while pressing in the butt direction, whereby the end faces of the relief portion are brought into a butt state, so that the welded joint portion is inevitably formed. The formation of a raised weld bead portion is prevented.

が極めて悪いという欠点を有していた。However, according to the above-mentioned welding method, there is a large disadvantage that the bonding strength is weak because a non-welded portion is present in the surface layer. In this case, a relief part which requires a relief must be formed, and a great deal of time is required for forming the relief part. Further, according to this method, it is considered that a raised bead portion is not generated at the weld joint portion, but a slight welding mark portion is generated at a portion where the relief portion is provided and welded and joined. Needless to say, finishing work for the welding mark was required. Therefore, this method did not sufficiently solve the problem. On the other hand, as a method of correcting the whitening phenomenon of the welded part surface,
There is a conventional technique called a touch-up method.
A paint of a similar color to the color of the material surface, that is, a touch-up paint is applied to the site where the whitening phenomenon occurred,
Since the curing time of the touch-up paint is long, the productivity is extremely low.

異なるため、その欠陥の修正が一層必要となる。Next, the bead removing portion 14, which is the seam of the end portion 12 of the synthetic resin window frame material 10 from which the weld bead portion 13 has been scraped off as described above, is provided on the surface of the resin material by the above-mentioned cutting process. Plastic deformation is caused, and the hue changes to a white color at the portion, that is, a whitening phenomenon called brushing occurs. Such a whitening phenomenon that has occurred in the bead removing section 14 significantly reduces the commercial value of the synthetic resin sash and is not preferable. In particular, when the wood grain pattern skin layer 10a is provided on the synthetic resin window frame material 10, the hue of the whitened bead removing portion 14 and the hue of the wood grain surface layer portion are significantly different, so that the defect needs to be further corrected.

It has been found by experiments of the inventor that the warm air radiation basically requires only a short required time of about 1 to 2 seconds. Due to this warm air radiation, the color that temporarily changed white due to the plastic change returns to the original color or pattern of the synthetic resin. The hot air radiated by the hot air heater 40 is heated in a temperature range of + 30 ° C. to −30 ° C. of a glass transition temperature according to the material of the synthetic resin window frame material,
By relieving the stress generated after the bead is removed, the whitening phenomenon is eliminated and the defect is corrected.

る。An embodiment of the above-mentioned warm air blower 40 will be described with reference to FIG. The hot air device 100 shown in FIG. 7 includes the above-described hot air blower 40 and the compressor 90, which are connected by an air hose 41. The warm air heater 40 uses a hand-held industrial dryer having a main body having a size of about 200 mm, and is used when welding a synthetic resin such as vinyl chloride. The hole diameter of the nozzle 42 at the tip is about 3 mm, and the nozzle 42 is heated and radiated to the material to be processed at intervals of 50 to 60 mm. 43 is a power cord, 44 is an ON-OFF switch, and 45 is an air volume adjusting lever. The air volume is arbitrarily adjusted by the member to be processed. The hot air heater 40
Shows an example, and about 200
Any material can be used as long as it can be heated at a high temperature of about ° C. In addition, the same device as that described above is appropriately employed as a device for laser beam irradiation or infrared irradiation.

し、好ましくはない。When the heating temperature exceeds the glass transition temperature + 30 ° C. due to the above-mentioned hot air radiation, fluidization of the surface structure of the synthetic resin window frame material becomes active, and the shape and surface appearance of the material to be treated change. As a result, the plastic change occurring on the surface, that is, the whitening phenomenon is eliminated and corrected by stress relaxation. The heating temperature is glass transition temperature -30 ° C.
If it is lower, it takes time to relieve the stress, which impairs productivity and is not preferred.

まい好ましくはない。A similar effect can be obtained by laser beam irradiation, infrared ray irradiation, heating by contact with a heat plate, or any combination thereof, instead of the above-described warm air blower 40. In the case of the above-mentioned heating method using hot air radiation, the heating range is desirably spot heating of only the defective portion, and the hot air emission time is preferably about 1 to 2 seconds. In the case of laser beam irradiation or infrared irradiation, the spot is heated, and the time is 1 to
2 seconds is appropriate. When the heating temperature is low, it is needless to say that a time of 2 seconds or more may be applied. However, if the temperature is too high for a certain period of time, the gloss of the surface of the material is undesirably reduced.
