Rotational control device for wiping material dispensing drum comprises lever articulated at base by two spindles against return spring, lever upper end extending beyond upper edge of drum receptor cheek web

摘要

The drum rotational control device is equipped with a profiled lever (20) articulated at its base against a return spring. The lever is equipped in its upper part with a support spindle of a pair of freely rotating pulleys (15,16). The lever is articulated by two spindles (20b,20c) located along an angular sector concentric with the drum articulation axis (4a). The drum receptor cheek web (2c) has two oblong slots formed in sectors concentric with the drum axis opening and reception zone. The upper end (20d) of the lever goes beyond the upper edge of the reel holder cheek web.
