ABSTRACT:
An apparatus (3) is installed in place of a cigarette support, for example. The force applied by loads (22, 23) to a force-measurement cell (31), mounted on a motorized slider (33) and moving parallel to said loads, is measured as a function of the displacement. A processing unit plots a graph depicting the force measured as a function of the displacement; any imperfection of the surface condition of the slides (22a, 23a) can be spotted on the graph. The movement-checking method and apparatus apply to the checking of any rectilinear movement of a guided object subjected to a constant force, and particularly to the checking of the state of wear of the slides of equipment for measuring the compressibility of articles produced in the tobacco industry.
