<p>A guide body (11) has two longitudinal flat surfaces (15,16) olaced at 90 degrees and enclosing the guide body. A handle (12) is fitted to the guide body by screws (21,22) one of which serves as a swivelling point for the handle, while the other fits in a tapping of the guide body and has a tightening nut. The base (23) of the handle has an opening (24) so that after loosening the nuts, the blade (14) fitted to the handle can be swung sideways, placing it off the angle bisector to the required amount. The cut is then led along a line with an additional width of the strip, so that the edge bears up exactly against the wall of the room.</p> |
