  • a towel dispenser is known from document US Pat. No. 6,267,460 B1 GAIDE ET AL, which dispenses a certain length of used towel after the fresh towel has been pulled out, so that a towel loop is formed which enables the user to comfortably dry his hands.
  • a disadvantage of this known towel dispenser is that improper operation, i.e. by repeatedly pulling out fresh towels briefly one after the other and before pulling in the used towel, can form a bottom loop, which subsequently cannot be completely drawn in while the towel is being drawn in.

Abstract

L'invention concerne un distributeur d'essuie-main (1) comprenant un dispositif d'entraînement (14) comportant en outre un mécanisme de levier (200), qui accouple en rotation le cylindre de guidage (25) et le cylindre d'entraînement (13) lors d'une activation d'une commande à minuterie (16) par l'intermédiaire d'une transmission mécanique (20), de sorte que le mouvement de rotation du cylindre de guidage (25) permette lors du dévidage d'essuie-main propre (6) à la fois de tirer l'essuie-main vers l'intérieur et de l'enrouler sur le rouleau à essuie-main sale (11) par l'intermédiaire du cylindre d'entraînement (13), le mécanisme de levier (200) pouvant être actionné au moyen de la commande à minuterie (16) après l'écoulement de la durée (Δt) par l'intermédiaire de la transmission mécanique (20), de sorte que le cylindre de guidage (25) et le cylindre d'entraînement (13) soient découplés en rotation. Cette invention concerne en outre un procédé pour faire fonctionner le distributeur d'essuie-main (1), comprenant les étapes supplémentaires qui consistent : à accoupler en rotation le cylindre de guidage (25) et le cylindre d'entraînement (13) au moyen d'un mécanisme de levier (200), de sorte que pendant l'écoulement de la durée (Δt), un mouvement de rotation du cylindre de guidage (25) soit engendré lorsqu'une longueur (ΔL) supplémentaire d'essuie main propre (6) est dévidée, de manière que le cylindre d'entraînement (13) permette à la fois de tirer une longueur d'essuie-main (ΔL) à l'intérieur et de l'enrouler sur un rouleau à essuie-main sale (11), une réinitialisation et une nouvelle activation de la commande à minuterie (16) se produisant simultanément ; et à actionner le mécanisme de levier (200) après l'écoulement de la durée (ΔL) au moyen de la commande à minuterie (16) par l'intermédiaire de la transmission mécanique (20), de sorte que le cylindre de guidage (25) et le cylindre d'entraînement (13) soient découplés en rotation.
