Abstract
An article turnover assembly (16) for transporting flat envelopes and the like while turning them over 180 degrees includes upper and lower crowned entrance and exit pulleys (22 and 24; 52 and 54) having two flexible endless belts (18 and 20) extending between the lower entrance pulley and the upper exit pulley and the upper entrance pulley and the lower exit pulley. The belts are twisted 180 degrees between the entrance and exit pulleys with each having at least one span contiguous to a corresponding span of the other. Registration of envelopes (10) is established at the entrance and is maintained by a horizontal flat registration plate (60) located about half of the travel distance between the entrance and exit pulleys. In addition, two opposed idler wheels (64 and 66) bias the spans together above the horizontal flat registration plate at about 3/5 of the travel distance through the assembly. Contoured stationary plows (84 and 86) are included at a downstream end of the contiguous belt spans to assist in turning the envelopes over.
