Plates (2;) are conveyed continuously in a conveying direction, whereby at least a first edge (15) of a plate Is provided with an edge profile by means of a rotating edge milling tool. A corner (16) connecting, the first edge and a second edge (17) of the plate is rounded at least partly by means of a rotating milling tool (12a, 12b) having a peripheral profile corresponding to a desired corner edge: profile of the plate. The rotating corner milling tool is controlled to be displaced along the continuously moving plate so if) at the rotating garner milling tool moves next to a corner to: he mimdeell and Is subsequently controlled to fee displaced simultaneously in the conveying direction (D) and m a transverse direction to Hie conveying, direction so that if follows a trajectory describing at least a part of: a desired rounding of the corner in a coordinate system fixed to the continuously moving plate.
A method of continuous edge processing of plates (2), whereby the plates are conveyed continuously in a conveying direction (D), and whereby at least a first edge (15) of a plate (2) is provided with an edge profile by means of a rotating edge milling tool having a peripheral profile corresponding to a desired edge profile of the plate, characterised by that at least a corner (16) connecting the first edge (15) and a second edge (17) of the plate (2) rounded at least partly by means of a rotating corner milling tool (12a, 12b) having a peripheral profile (13) corresponding to a desired corner edge profile of the plate, by that the rotating corner milling tool (12a, 12b) is controlled to be displaced along the continuously moving plate (2) so that the rotating corner milling tool (12a, 12b) moves next to a corner (16) to be rounded, and by that the rotating corner milling tool (12a, 12b) subsequently controlled to be displaced simultaneously in the conveying direction (D) and in a transverse direction to the conveying direction so that the rotating corner milling tool follows a trajectory describing at least a part of a desired rounding of the corner (16) coordinate system fixed to the continuously moving plate.
A method of continuous edge processing according to any one of the preceding claims, whereby subsequently to rounding the corner (16) connecting the first edge (15) and the second edge (17) of the plate (2), the first edge is provided with a layer of lacquer by means of a lacquer application roller (23) having a peripheral profile corresponding at least substantially so the desired edge profile of the plate, whereby the lacquer application roller, over at least almost the entire length of the first edge, rolls on the first edge of the plate with a peripheral speed corresponding at least substantially to the velocity of the plate in the conveying direction, and whereby, when the lacquer application roller is at a position at the corner connecting the first edge and the second edge of the plate, the peripheral speed of the lacquer application roller is changed in relation to the velocity of the plate in the conveying direction so that an extra amount of lacquer is deposited at said corner.
A method of continuous edge processing according to any one of the preceding claims, whereby the following steps are performed in succession:
A continuous edge processing device for edge processing of plates, including a conveyor (3) for continuous conveyance of plates (3) in a conveying direction (D) and a rotatable edge milling fool having a peripheral profile corresponding to a desired edge profile of a plate and being adapted to provide at least a first edge of a plate with an edge profile, characterised in that a rotatable corner milling tool (12a, 12b) having a peripheral profile corresponding to a desired corner edge profile of the plate is adapted to round at least a corner (16) connecting the first edge (15) and a second edge (17) of the plate (2), in that the rotatable corner milling tool (12a, 12b) is arranged displaceably in the conveying direction (D) and in a transverse direction to the conveying direction, in that a position and/or a velocity detection device is adapted to continuously detect the position and/or velocity of the plate in the conveying direction, and in that a control unit is adapted to, on the basis of the detected position and/or velocity of the plate, control the position of the rotatable corner milling tool to follow a trajectory describing at least a part of a desired founding of the corner in a coordinate system fixed to the continuously moving plate.
A continuous edge processing device according to claim 28, wherein a first laser detection device is adapted to detect the leading or trailing edge of the plate at said certain position in the conveying direction.
A continuous edge processing device according to claim 38, wherein a second laser detection device heated at a position after the position of the first laser detection device in the conveying direction is adapted to detect the leading or trailing edge of the plate at said certain position in the conveying direction.
