Abstract: The device useful as a film cutting tool for removing film projection on a glass edge of a laminated safety glass panel in a laminated glass cutting machine, where the device is integrated or integratable into the laminated glass cutting machine, comprises a plate-shaped mounting element, to which a cutter is provided, extends itself vertical to a surface plane of the laminated glass panel to be processed and protrudes on front-side of a film cutting knife with an operating side. A spacer roller is subordinated behind the cutting edge of the film cutting knife. The device useful as a film cutting tool for removing film projection on a glass edge of a laminated safety glass panel in a laminated glass cutting machine, where the device is integrated or integratable into the laminated glass cutting machine, comprises a plate-shaped mounting element, to which a cutter is provided, extends itself vertical to a surface plane of the laminated glass panel to be processed and protrudes on front-side of a film cutting knife with an operating side. A spacer roller is subordinated behind the cutting edge of the film cutting knife in an operating direction of the film cutting tool and is arranged at the mounting element. The rotating axis of the spacer roller is directed parallel to the cutting extension of the cutting knife. The lateral lines of the spacer roller pointing to the laminated glass panel further projects towards the laminated glass panel than the cutting edge of the cutting knife. The spacer roller consists of plastic. The cutting knife is displaceably arranged, so that its cutting board is changeable from a knife holding block. The spacer roller is displaceably arranged, so that the board of its lateral lines is variable relative to the cutting board. The film cutting knife and the spacer roller are arranged together in front of and back to the mounting element in a relocatable manner. The mounting element is a mounting plate element (1) with two longitudinal edges (2, 3), an anterior front edge (4) and a rear edge (5), where the foil cutting tool element is arranged to a surface of the mounting plate element. A supporting plate (31) parallel to the longitudinal edges is displaceably retained parallel to each other with guiding elements between the mounting plate element and supporting plate on a surface of the mounting plate element. A knife supporting block is fastened to the front end of the supporting plate, and protrudes the anterior front edge of the mounting plate element and mountably, detachably supports the film cutting knife, whose cutting edge runs parallel to the front edge and/or vertical to the glass edge of the laminated glass panel. The knife supporting block and/or the supporting plate is connected with a roller supporting device having a supporting arm, which extends parallel to the supporting plate, is displaceably arranged together with the supporting plate and rotatably supports the spacer roller on the front side e.g. between two fork arms extending towards front. The rotating axis of the spacer roller extends parallel to the knife of the cutter and is arranged in the operating direction of the film cutting tool with a relative small distance of 3-10 cm directly behind the knife. The shaft and/or rotating axis of the spacer roller is adjustable in a back and forth manner and adjustably arranged between the fork arms. A piston cylinder arrangement is arranged next to the supporting plate on the mounting plate element extending parallel to the longitudinal edges, where the rear end of the piston cylinder arrangement is fastened at a bearing block and the knife supporting block is fastened at the front end of the piston cylinder arrangement, which projects the mounting plate element. The laminated glass cutting machine has a feed table and an operating table in transport direction of the laminated glass panel, where the operating table is equipped with operating bridges and has stop elements that are arranged from each other at a distance and extend parallel to the transport direction for the longitudinal edges of the panel and further stop elements that are arranged from each other at a distance and extend vertical to the transport direction for the front edge of the panel. two film cutting tools are integratedly arranged in the cutting machine, where the one cutting tool is fixedly installed at the front end of the feed table that is viewed in transport direction in the area of the longitudinal edge of the feed table and the other cutting tool fits back to a linear guiding device, which is processable in a process direction, in the area of the front end of the feed table. The longitudinal edge of the panel is processed when the panel is transported from the feed table to the operating table. The linear guiding device extends parallel to the front edge of the feed table, and is arranged outside of the transport space path of the panel. The film cutting tool is linearly processably fits to the linear guiding device with corresponding driving unit, so that the front side of the panel is processable. The film cutting tool is automatically displaceably arranged to the linear guiding device, so that it is displaced and/or pivoted from the transport space path of the panel. The mounting plate element is arranged vertical to the plane of the feed plane, so that the cutter of the cutting knife and the lateral lines of the roller are directed vertical to the glass edge of the panel. The linear guiding device is arranged to one of the operating bridges of the operating table. An independent claim is included for a method for removing film projection on a glass edge of a laminated safety glass panel in a laminated glass cutting machine.
