Abstract

PURPOSE:To perform efficiently continuous production of even a long-sized and wide matter of a sheet made of synthetic resin or rubber, by a method wherein butted end faces of the sheets are joined by welding to each other. CONSTITUTION:End faces of sheets 2 made of synthetic resin or rubber, which are to be joined to each other are butted against each other and the end faces are joined to each other. On this occasion, butting end faces of the sheets 2 are joined to each other by welding. Hereupon, since the sheets 2 are joined to each other by butting against to each other by welding by making use of heating of a material as a material of the sheet, joining can be performed not only between the sheet 2 comprised of materials identical with each other but also between the sheets 2 comprised of materials different from each other. Since joining by welding is performed like this, continuous production of even a long-sized and wide matter.

In recent years, large-sized laminated glass has been required as the opening of buildings such as buildings has become larger. ing. In order to produce such a wide laminated glass, a sheet sandwiched between the glasses as an intermediate layer is also required to have a large size. Therefore, a method of obtaining a sheet of a desired size by joining a plurality of sheets Has also been tried.

た。However, when the ends of the sheets are overlapped and joined together by using an adhesive or the like, the overlapping portions become thicker, so that the sheets are not uniform in thickness, and the degassing of the laminated glass is poor. It is also not preferable in terms of appearance and optical distortion. In addition, when a synthetic resin or rubber sheet is used for joining in addition to the use of laminated glass, a flat sheet cannot be obtained if there is a laminated portion, and there is a problem in appearance.

Among these joining methods, the methods mainly used are a method of applying an adhesive to the abutting portion to join the sheets, a method of joining the sheets by adhering a tape-like thin sheet from above the abutting portion, (See JP-A-3-55348 and JP-A-63-255454).

ことを知見した。Means and Actions for Solving the Problems As a result of earnest studies to achieve the above object, the present inventor has abutted the end faces of synthetic resin or rubber sheets to be joined to each other and joined the end faces to each other. In the joining method, by joining the abutting end faces of the sheets by welding, that is, instead of abutting and joining with an adhesive, the abutting end faces of the abutted sheets are irradiated with laser, ultrasonic waves, high frequency, or the like. A wide sheet can be efficiently and continuously produced by causing the sheets to generate heat by the heat generating action and by joining the abutting end faces of the sheets by the melting action of this heat generation, and the joined portions of the sheets are not conspicuous. We also found that a wide sheet with excellent appearance can be obtained.

的にも歪みのないものであった。Example 9 Two sheets were joined in the same manner as in Example 7 except that a 0.1 mm PET film was used and the welding time was 2 seconds. This bonding sheet had sufficient strength on the bonding surface, and the laminated glass produced using this bonding sheet was such that the bonding portion was not visually recognizable and there was no optical distortion.
