TOOL FOR PROVIDING AN AK TYPE TAPERED EDGE IN PLASTERBOARD

摘要

Tool for providing an AK type tapered edge at straight plasterboard edges, the tool having a metal "Π''-shaped skeleton (1) the vertical components of which serve as guides. A metal blade (3) which is adjustably and obliquely mounted in the skeleton by means of a detachable metal component (2) and three metal screws (4). The tool embraces the edge of the plasterboard so that it is positioned between the guides and reaches the horizontal part of the skeleton (1) whereby the edges are cut by one move of the metal blade (3) along the length, width and thickness of the plasterboard, removing the coating paper and part of the plaster. In this way the cut edges of the plasterboard are shaped into AK type tapered ones.
