The invention concerns a control and safety device characterised in that said transmission means (10) consist of a belt mounted between the drum (4) and the shaft (9) in a floating mount, the shaft receiving said belt being arranged in its central part opposite the groove formed on the drum in a twin-wheel configuration (9a), having a dimension greater than the width of the groove (4b) formed on the drum, so as to enable an oblique lateral displacement of the belt, which thus accompanies, according to a limited amplitude (a), the longitudinal direction in which the paper strip is being pulled out of the dispenser by the user. |
