Abstract

La présente invention concerne un mandrin de bobinage, un distributeur d'essuie-mains comportant un tel mandrin de bobinage et un procédé d'utilisation du distributeur d'essuie-mains. Le mandrin de bobinage (6) comprend une roue dentée (17), coopérant avec un moteur électrique, à laquelle une tige de serrage (19) est fixée. La tige de serrage (19) est disposée dans une rainure (22) d'une surface périphérique d'un corps de rouleau (20), lequel peut tourner par rapport à la roue dentée (17). Dans une position de chargement du corps de rouleau (20), dans laquelle la tige de serrage (19) est espacée des parois latérales de la rainure (22), une partie d'extrémité d'une bande d'essuie-mains peut être mise en boucle sous la tige de serrage (19). En faisant tourner la roue dentée (17) dans une direction d'enroulement, le corps de rouleau (20) est réarrangé par rapport à la tige de serrage (19) dans une position d'arrêt, dans laquelle une section de la partie d'extrémité entre une surface de butée (24) sur le corps de rouleau (20) et une face de serrage opposée (25) est serrée sur la tige de serrage (19) et elle est maintenue de manière fiable lors de l'enroulement. Si la bande d'essuie-mains est enroulée comme rouleau usé sur le corps de rouleau (20), le serrage à la partie d'extrémité est libéré en faisant tourner la roue dentée (17) dans une direction opposée d'enroulement et le mandrin de bobinage (6) est retiré du rouleau usé vers le côté de la roue dentée (17).
