Abstract
Method of direction control consisting in producing one or more parallel reference lines (7,8) that may be manipulated in such a way that their directions become parallel to the intended direction and with the help of plane mirrors making images (9,10) of the reference lines and images (12,13) of the object the straightening up of which is to be controlled. Implement for use at the method.
