electrodynamic forces for moving waste or trash from beneath and around textile processing equipment are produced by a set of parallel electrodes encased in a plastic panel and connected to a polyphase source of ac power. such an apparatus is known as an electric curtain of the contact type, or more simply, an 'electric panel. ' when the panel is energized, particles in contact with it become charged and are levitated and transported. an electric panel is mounted beneath an experimental opener-cleaner that is considered representative of cotton trash-removing machines. trash is separated from fibers by mechanical action at a rate implied to be a function of the opener-cleaner's velocity and the amount of cotton processed particles of trash, linters, and fine dust fall onto the electric panel and are removed from beneath the opener-cleaner by the electrodynamic forces of electrosweep, which removes trash at its maximum production rate of 20 mg/s.
