<p>PROBLEM TO BE SOLVED: To prevent the application of an excess load on a dust collecting sheet for an air cleaner when the sheet is fed from a supply table to be taken up onto a take-up table. SOLUTION: A dust collecting sheet 20 is pulled out from a dust collecting sheet roll 20a on a rotatable supply table 10 and from the opening 3a of a dust collecting wall 3 outside the wall 3, wound on a dust collecting periphery and returned, and returned again from the opening 3a to the inside of the dust collecting wall 3 to be taken up onto the winding core of a take up table 12. The supply table 10 and the take-up table 12 are equipped with a pulley A and a pulley B, which are connected together by a belt 18. By rotating/operating the take-up table side, the table 10 is rotated by a driving system consisting of the pulleys A, B and a belt, and the sheet 20 is pulled out smoothly to be taken up.</p> |
