Cleaning device

Abstract

Abstract PURPOSE: To wind up a web by each fixed amound at all times and achieve the longer life of the web with simple constitution by providing a roller making press- contact with the outside circumference of the web on one of a winding shaft or feed shaft and revolving this roller at a fixed speed. CONSTITUTION: A cleaning web 7 is suspended by way of a press-roller 8 between a feed shaft 9 and a winding shaft 10 and the winding shaft 10 is held rotatably at one end of a lever 11. A spring 12 is set to the other thereof and this winding shaft is held press-contacted at all times with a constant-speed revolving roller 13 by the spring 12. The constant-speed roller 13, which is driven by a fine speed motor, revolves in the arrow B direction to wind a web 7 subseqnetly on the winding shaft 10 by surface friction force. A thin covering 13a of rubber for the purpose of giving friction force is formed on the constant-speed roller 13 surface. Thereby, the web on the winding shaft 10 may be wound always at every fixed amount and the life of the web may be prolonged. COPYRIGHT: (C)1981,JPO&Japio
