DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a device for dividing laminated glass, especially twin-pane laminated glass, with two plate-shaped supports for the laminated glass, in which one of the two essentially horizontally aligned supports is rigidly attached in the machine frame and the other support is mounted to swivel around a horizontal axis located in the area between the supports and can move in the direction of the plane of the support fixed to the machine transversely to the latter support, with means for fixing the laminated glass on the supports which are located on the support edges adjacent to the area between the two supports, with cutting tools which can be moved in the abutting area between the two supports for scratching the laminated glass on both sides, and with a means for splitting the plastic film located between the two laminated glass panes.
2. Description of the Related Art
A device of this type is known from EP 596 852 A1. In this known device, in contrast to earlier proposals in which the film is melted between the laminated glass panes by supplying heat, the film will be split using a plasma jet which is moved along the opened fracture line in the laminated glass. This device has proven effective in and of itself, however the cost of using a plasma jet or as likewise proposed a laser beam is relatively high; this relates both to engineering and also safety regulations.
SUMMARY OF THE INVENTION
The object of the invention is to devise a reliable device for dividing laminated glass which operates without a heat supply and which has a simple structure, proceeding from the device of the initially mentioned type.
According to the invention, this object is achieved by the device for splitting the plastic film being a cutting device which has one blade and which can be moved in the area between the two supports.
Advantageous and preferred embodiments of the invention are the subject matter of the subclaims.
In the device according to the invention for splitting the film between the laminated glass panes a cutting device with one blade is used; this has the advantage that special measures for producing a laser beam or plasma jet or the heating of air or operation of an infrared radiation source are unnecessary. It is simply enough to move the blade of the cutting device along the opened fracture in the laminated glass; this is easily possible since there are slides and guides anyway along which the cutting tools which act on the laminated glass from the top and from the bottom are moved.
