<p>The invention concerns a device for controlling and limiting the drum rotation in a wiping material dispenser comprising a housing (1), a cover (3), the housing having flanges (2) supporting a reel stand (4), a drum (5) with a cutting device (6), the drum including at one of its ends an eccentric element (7) associated with a release and return spring (8) the other end being associated with a control flywheel (9). The invention is characterised in that it is formed by a single component (10) arranged and shaped like an irregular crown to ensure various functions controlling and limiting the drum (5) rotation when a strip of material is cut, said component being in the form of a planar part and having an external profile combining curvilinear and rectilinear irregular successive shapes with projecting zones, and said component is fixed on one of the drum lateral flanges in free and floating assembly, and capable of moving according to the drum rotating conditions, in normal or accelerated rotation for controlling and stopping the drum.</p> |
