Abstract
The invention proposes a solution for cutting a sheet of gypsum board quickly and allowing a flat cut edge to be obtained. The invention relates to a carriage comprising a chassis (101) fitted with: —means (102) for collaborating in a sliding manner with a cutting guide (200); —a handle (110) that can rotate with respect of the chassis (101) and comprises a means (111) for grasping, a retractable engagement claw (113) and a housing (112) to hold a blade (300); —a section piece (120) provided with at least three notches (A, B, C) in which to lock the rotation of the handle through reversible engagement of the claw, the notches being arranged such that: •the first notch (A) allows the blade to be retracted so that it is not in contact with the sheet; •the second notch (B) allows the blade to be arranged at an angle α to the sheet of gypsum board, in firm enough contact with the sheet to score it in order to form a cutting edge; •the third notch (C) allows the blade to be arranged at an angle β to the sheet of gypsum board in firm enough contact with the sheet to trim the cutting edge.
