Abstract

Static neutralizing or discharge devices have previously been used to remove static charge or buildup that may occur in copy sheets or other areas in automatic reproducing apparatus. Typically, the static electrical charges are generated by contact by the paper with various parts of the office machines. Buildup of these charges on the sheets can cause the sheets to tend to stick together thereby increasing the difficulty in physically handling the sheets from station to station in a reproducing machine. Static eliminator brushes made from stainless steel fibers about 12.5 microns in diameter configured into the form of a brush strip have been used to contact the copy paper and reduce the static charge that has

been built up on the copy paper. Two difficulties have been observed with the use of stainless steel fibers in that they tend to entangle easily during use which causes an unacceptable short fall in operational lives. In addition, the fibers tend to fracture and form small pieces which may be carried by air streams within the machine leading to contamination of machine. In particular, electrical components succeptable to being electrically sh...
