ABSTRACT:
A method for assembling an apparatus that removes solid waste material from a stream of water. The apparatus sits in a channel within which the water containing waste material flows. A plurality of vertically oriented, laterally spaced apart, rotating screens are driven by sprocket segments and provide a filtering function. The screens are formed by plural loops of articulated links. Each link includes a horizontally-extending part that lifts solid matter from the stream as the screens rotate. The assembly method includes placing the links on shafts in a predetermined pattern that creates a frusto-conical space bordered by links. The frusto-conical space provides ample clearance space for each sprocket segment and ensures that the sprocket segments will not rub against the links which in turn prevents the parts of the apparatus from becoming misaligned with respect to one another so that the apparatus may operate for extended periods of time without requiring adjustment.
