<p>A towel dispenser for a continuous band (40) includes a cabinet containing a frame (30) formed by two parallel walls (31, 32) between which there are pivoted a drive roller (50) rotatable around an axis (38) due to the friction of the band (40) being unwound by the user's pull, a roller (60) for winding up the soiled band (40) onto a second roll (46) through a kinematic connection with said drive roller (50), a roller (57) for taking up the soiled band (40) within the cabinet through a kinematic connection with an energy accumulator charged by the winding roller (60), an idle roller (70) arranged above the drive roller (50) and pivoted between two plates which are in turn pivoted on the walls (31, 32) so as to oscillate forward under the pulling action exerted by the user on the band (40), as well as a ratchet gear mobile between a rest position wherein the energy accumulator is free and an engagement position wherein the energy accumulator is charged by the rotation of the winding roller (60). The engagement position is reached due to the above-cited forward oscillation of the plates and is maintained for a certain time after the ceasing of the user's pulling action thanks to a pair of suction cups which delay the return of the multiple lever ratchet gear to the rest position and the subsequent release of the energy accumulated by the accumulator which drives the take-up roller (57) so as to take up the soiled band within the cabinet, the length remaining outside being pulled close to the lower surface of the cabinet whereby the soiled band is not visible and the next user does not have the tendency to wipe his hands in the exposed soiled band rather than pulling out a clean portion thereof. <IMAGE></p> |
