An elliptical garment hanger simulates a garment wearer’s shoulder and upper chest and back so as to prevent hanger bumps on garments. The feeding and conveying system includes at least one feeder having a magazine containing a plurality of articles of sheet material, for example, signatures, a rotatable disk for separating the sheet material from the magazine, and a feed drum for transferring the sheet material from the magazine to a conveyor. In a preferred embodiment, a plurality of signal samples of the frequency shifted signal in each of said bands are accumulated to produce a vector for each band, and the frequency estimate is selected in one of said bands, based upon the magnitude of the corresponding vector. The arrangement is such that the support member is movable along the length of the base member.
