A liquid filter and method is disclosed comprised of a housing (12) defining a filter chamber (14), with a filter belt (22) advanced into the filter chamber (14) and receiving liquid flow to filter the liquid. Different sections of the filter belt are alternately positioned in the filter chamber (14) by a pair of drive-take up rollers (28, 30) each positioned on one side of an entrance opening to the filter chamber (14), which are driven in opposite directions after alternate cycles. Each section of the filter belt (22) is scraped when exiting and subsequently cleaned with washing sprays as the particular section is advanced back into the filter chamber (14). The filter belt (22) is detachably attached at either end to a respective roller by a sewn in flexible element received in an undercut groove in the roller surface. <IMAGE> |
