Open the CIPO recordAbstract From the Canadian patent
An apparatus for automatically removing cake deposits from the surface of filter cloths within a filter press is disclosed. The apparatus includes a rod for suspending the cloth in a substantially inverted "V"-shaped configuration. The cloth is then slackened by lowering a rod over which the cloth is folded. The rod is then suddenly forced upwardly under the driving force of a loading means. The rod draws the cloth to a taut tensioned, condition, imparting a whip-like motion to the fabric of the filter cloth. This imparted motion serves to disengage the cake from the filter cloth.
