Abstract:
A laminate sheet having a pressure sensitive adhesive layer, characterized in that the adhesive layer is superimposed on an embossed release layer, whereby embossed shapes of the release layer are transferred onto the adhesive layer. Upon conducting a lamination process the embossed adhesive layer is separated from the release layer and thus functions to prevent the formation of air pockets between the adhesive layer and a subject sheet and the detachment of the laminated adhesive layer from the subject sheet.
Abstract:
A device for eliminating static electricity from protective film of a laminated sheet in a laminator is disclosed. A longitudinal fan is set in the laminator. An air suction port is formed on the bottom wall of the laminator, thus guiding atmospheric air to the fan. An air passage is formed in the laminator so as to guide the pressurized air current from the fan to the rear wall of the laminator. An air exhaust port is formed on the rear wall of the laminator at a position around the rear end of the air passage, thus discharging the pressurized air into the atmosphere. In the fan, a drive motor is installed at one end of a longitudinal housing, while a plurality of longitudinal blades are regularly arranged in the housing so as to form a cylindrical blade body. An inlet opening is longitudinally formed at the lower portion of the housing and guides the atmospheric air to the blade body, while an air outlet opening is longitudinally formed at the upper portion of the housing so as to discharge the pressurized air current from the fan into the air passage.
Abstract:
A laminator film having a plurality of continuous, fine grooves on its surface in the lengthwise direction of the film. When the laminator film and a target film to be laminated are passed between a pair of hot, engaged rollers, the air between the grooved surface and the target film can be guided out through the grooves while the grooves are flattened by the pressure and heat of the rollers. Thus, it is completely preventive of air accumulation by virtue of their continuous fine grooves, giving a great improvement in adhesiveness, surface smoothness and transparency to the resulting laminated product.
Abstract:
A laminating method for objects such as important documents, old documents and other printed matters to prevent a forgery or quality degradation of those objects or to protect the surfaces of those objects. In the lamination method, a released paper sheet, released synthetic resin film or non-released synthetic resin film is laminated using a thermoplastic resin solution, thereby forming a lamination sheet as a medium, so that the resultant synthetic resin thin film on the lamination sheet is subsequently transferred onto an object as the lamination sheet passes through a nip defined between pressing rollers along with the object.
