Abstract
The contacting arrangement comprises at least one set of parallel plates, which are equally spaced apart and extend at an angle to the horizontal. Each of said plates is formed with a plurality of slots, which are arranged in at least two generally parallel rows, which are transversely spaced apart in the vertical direction. Each of said slots is defined on at least one side by a lug, which is bent from said plate. The longitudinal directions of the slots of adjacent rows of each plate are in mutually opposite senses from the vertical.
