A method of constructing a rotary drum filtering apparatus, the method comprising the steps of: placing a cover element end on a support portion, placing an overlying portion over the cover element end and inserting a respective tab into a respective opening in the support portion, moving the overlying portion along the support portion, so that the tab second portion is then under the support portion, thus holding the cap on the clip, with the cover element end trapped in between. |

1. A method of constructing a rotary drum filtering apparatus including: a drum structure that supports a circumferential filter medium, the drum structure having filtrate compartments communicating with openings in the filter medium for receiving liquid drained through the latter, the drum structure including a supporting drum, rib elements supported on the drum and defining the filtrate compartments which extend generally longitudinally along the drum circumference, and cover elements, each having an end mounted to the rib elements by a clip and an overlying cap, the cover elements forming a cover circumferentially around the supporting drum over the filtrate compartments, each clip having a cover element edge support portion, and each cap having a cover element edge overlying portion, the overlying portion including a plurality of tabs spaced apart along the longitudinal axis of the overlying portion, each tab having a first portion that, when the drum is assembled, extends perpendicular to the support portion, and a second portion angled relative to the first portion and extending parallel to the longitudinal axis of the cap, the support portion having tab receiving openings spaced apart along the longitudinal axis of the support portions,
the method comprising the steps of: placing the cover element end on the support portion, placing an overlying portion over the cover element end and inserting each respective tab into a respective opening in the support portion, moving the overlying portion along the support portion, so that the tab second portion is then under the support portion, thus holding the cap on the clip, with the cover element end trapped in between. |
