Abstract (en)
[origin: WO2011132134A1] The invention relates to a solution for rapidly grooving a piece of plasterboard, enabling the creation of a plane cutting edge and a precise cut-out of the layer(s) of paper or cardboard. To this end, according to the invention, the cutting is carried out in three main steps by means of a blade having a particular shape and sharpness: a step of grooving, a step of breaking the plasterboard, and a step of levelling the cutting edge. The invention therefore relates to a blade (300) for cutting a piece of plasterboard, characterised in that it comprises at least one grooving corner (301) having a plane face and a bevelled face.
