A control and safety device for a machine for dispensing strips of material having a belt mounted between a drum ( 4 ) and a shaft ( 9 ) in a floating mount. The shaft receiving the belt having an axle of narrower diameter than the shaft in its central part opposite a groove formed on the drum. The axle has a dimension greater than the width of the groove ( 4 b) formed on the drum, so as to enable an oblique lateral displacement of the belt, which thus accompanies, according to a limited amplitude alpha, the longitudinal direction in which, for example, a paper strip is being pulled out of the machine by the user.
